A method of manufacturing an extended content booklet label. Sheets are parallel folded to form a spine of a multi-up book log. The book log is overlaminated with an overlaminate to a major web having a longitudinal direction so that the spine is oriented perpendicular to the longitudinal direction of the web. The major web is continuously moved passed three or more longitudinally aligned cutting elements. Each cutting element cuts deeper than the previous cutting element for progressively slitting the major label web and overlaminated multi-up book log in the longitudinal direction only to form two or more minor webs.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a method for manufacturing extended content booklet labels (ECBL).

2. The Prior Art

Frequently product containers are identified by applying an adhesive-backed label to an outer surface of the container. Such labels retain their product-identifying purpose by remaining permanently affixed to the container.

Certain products which require extensive instructions or which are subject to significant government regulations require additional printed matter which is typically inserted into the product container. In the case of pharmaceuticals, the printed matter may be in the form of printed sheets, printed inserts, or printed outserts. An example of such may be seen in U.S. Pat. No. 5,685,530. While these various forms of printed matter have the benefit of providing a relatively large amount of information, their overall effectiveness is limited if they become separated from the product container.

U.S. Pat. Nos. 6,027,780 and 5,830,550 both entitled Booklets and Self Adhesive Labels Including the Same shows single labels and multi-up booklets adhered to a continuous web. A label product including a release liner having an upper surface and a booklet disposed on the upper surface of the release liner. In all embodiments, the outserts and booklets are directly adhered to the underlying web with double coated tape or adhesive transfer tape. In multi-up embodiments, the booklets are die-cut to separate them into individual booklet labels. Die-cutting is problematic as the number of pages in the booklets increase.

U.S. Pat. No. 6,576,315 entitled Multi-Ply Resealable Label shows booklets with windows adhered to a continuous web. A label includes a base label having upper and lower opposed surfaces and first and second opposed ends. A base adhesive coats the lower surface of the base label. A top panel overlies the upper surface of the base label and is joined to the base label adjacent the first end. The top panel has an upper surface. A tab having upper and lower opposed surfaces overlies the upper surface of the base label. An adhesive patch is interposed between the base label and the tab adjacent the second end. The adhesive patch secures the lower surface of the tab to the upper surface of the base label. A laminate cover overlies the top panel and the tab. A laminate adhesive secures the laminate cover to the upper surface of the top panel and releasably joins the laminate cover to the upper surface of the tab.

U.S. Pat. No. 6,432,500 entitled Label with Booklet shows a label with an overlaminate that extends beyond the label perimeter. A label with booklet comprises a liner material and a label having an upper and lower surface located on the liner. The label is secured to the liner by an adhesive layer on its lower surface such that the label can be peeled off the liner with the adhesive remaining on the lower surface of the label. A booklet is affixed to the upper surface of the label and comprises a plurality of stacked pages having edges including a top page and a bottom page, each of the pages being coextensive with each other and of smaller dimensions than the label. The booklet further comprises a cover member entirely covering the top page and extending beyond at least two opposing edges of the top page, the cover member having an upper non-adhesive surface, and a lower surface having an adhesive thereon by means of which the lower surface of the cover member is permanently adhered to the upper surface of the top page. The booklet is completely removable from the label by removing at least a portion of the cover member.

U.S. Pat. No. 5,846,623 entitled Adhesive Label/Leaflet Assemblies shows multi-up leaflets which are die-cut and then covered with a narrow overlaminate that forms shoulders at the edges to facilitate access to the leaflets beneath.

U.S. Pat. No. 6,432,499 entitled Nested Label shows a label with die cut windows applied to a release liner. A nested label includes a liner having a surface release, and a label removably bonded to the liner by an adhesive. The liner and label have respective die cuts spaced apart from each other at a skip in the liner release for obtaining different bond strengths between the label and liner on opposite sides of the label die cut.

U.S. Pat. No. 6,948,743 entitled Multilayer Label and Method of Making Same shows multi-page labels with staggered sheets to facilitate application to curved containers. A multiple layer label and a method of making the same are provided. Specifically, a label having a base layer for adhering to a container is provided wherein the label has an overcoat layer having an end that is removably adhered to the container. Moreover, the end that is removably adhered to the container is grasped by a user of the label and pulled, thereby removing the end of the overcoat layer from the container and swinging the layer away from the remainder of the label and exposing sublayers beneath the overcoat layer. The overcoat layer is adhered directly to the base layer, and at least portions of the sublayers. Each of the overcoat layer, sublayers, and the base layer may have indicia printed thereon for communicating information.

U.S. Pat. No. 6,179,335 entitled Product Label Bearing an Instructional Booklet shows a folded booklet adhered to a portion of a label. A two part identifying and instructional booklet having a label part and a booklet part. The front of the label has a small unvarnished region. The booklet is folded and glued closed with the free edges secured interiorly. An adhesive is printed onto the unvarnished region of the label and the folded booklet is adhered to the unvarnished region. The booklet has a tab portion to facilitate opening of the book during use. The tab portion faces the identifying portion of the label which extends longitudinally outwardly from the unvarnished region. The label may be placed onto a cylindrical container and bent in the longitudinal direction whereby the spine and folds of the booklet remain straight, flat and parallel to each other.

U.S. Pat. No. 6,439,614 entitled Nested Leaflet Label Structure shows a booklet adhered to a label. A nested leaflet label structure having an enhanced information carrying capacity. The nested leaflet label structure includes a base panel having a front face. A first leaflet is adjacent to the front face and comprises a first folded panel having a first fold extending substantially parallel to the first axis of the label structure. The first fold divides the first folded panel into a pair of first leaves each having inner and outer page faces. A second leaflet comprises a second folded panel having a second fold extending substantially parallel to the first axis of the label structure. The second fold divides the second folded panel into a pair of second leaves each having inner and outer page faces. A laminating layer overlies the base panel and the first leaflet. The second leaflet is nested in the first leaflet. An assembling adhesive adheres the second leaflet to the first leaflet.

Fold-out labels made from single sheets are shown in U.S. Pat. No. Re. 34,366 and U.S. Pat. No. 5,830,550. An example of a booklet which incorporates certain advantages of a label is disclosed in U.S. Pat. No. 5,324,559. The patent discloses a relatively simple booklet containing four sheets, i.e., eight pages. In all of these patents, the first page contains information which would otherwise be placed on the product label. The entire back page is adhered to the container leaving only the intermediate pages for instructional information. A further drawback of these patents lies in the fact that if their first page becomes detached from the booklet the product container would be unlabeled. U.S. Pat. No. 6,712,398 shows method for making removable inserts. U.S. Pat. No. 6,737,137 describes a method for manufacturing adhesive image transfer labels.

Accordingly, it would be desirable to provide a method for manufacturing extended content booklet labels which combines the efficiency of a continuous process for handling multi-up book logs with the instructional capacity of a multi-page booklet.

SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention to provide compact labels containing large amounts of information.

It is another object to provide booklets that are compactly mounted to labels.

It is a further object to provide a method for efficiently placing book logs onto a web.

It is another object to provide a continuous and progressive slitting operation to separate multi-up books into individual booklet labels.

It is a further object to provide multi-up booklet labels that are pre-trimmed in the longitudinal direction prior to the progressive slitting operation.

It is a further object to provide an extended content booklet that does not interfere with the label conforming to a cylindrical surface when adhered to a container.

According to a first embodiment of the invention there is provided a method of manufacturing an extended content booklet label. Large sheets are printed with information that will form several booklets. In the large sheet format the booklets are aggregated into a multi-up log book. The next step involves primary parallel folding sheets to form a spine 20d, 30d, 40d of a multi-up book log. The multi-up book log is overlaminated with an overlaminate to a major web having a longitudinal direction so that the spine is oriented perpendicular to the longitudinal direction of the major web. The next step involves continuously moving the web passed the cutting elements of a slitting station for progressively slitting the major web in the longitudinal direction only. Each cutting element cuts deeper than the previous cutting element to form two or more minor webs. In other words, the multi-up book log is separated into several booklets, and each booklets is carried on its own separate minor web.

The multi-up book may be further parallel folded to form a secondary fold parallel to the spine. The multi-up book log includes free sheet ends opposite the spine and the further parallel folding step includes further parallel folding the multi-up book to form two secondary folds that are parallel to the spine, where the free sheet ends are enclosed within the log. The web has a width direction perpendicular to the longitudinal direction and the overlaminate and multi-up book log are pre-trimmed in the longitudinal direction.

The major web is a major label web having a release liner and paper stock adhered to the release liner. The overlaminating step includes overlaminating the multi-up book log with an overlaminate to the paper stock. The web has a width direction perpendicular to the longitudinal direction and the overlaminate, multi-up book log and paper stock are pre-trimmed in the longitudinal direction. The overlaminating step includes overlaminating a series of multi-up book logs with a continuous overlaminate web to the paper stock. Alternatively, the overlaminating step includes overlaminating sections of laminate which are pre-trimmed in the longitudinal direction to adhere the log to the paper stock.

The continuously moving step includes continuously moving a major web passed the cutting elements of a slitting station for progressively slitting the major web to form two or more separate and independent minor webs. The continuously moving step includes continuously moving the web passed three or more longitudinally aligned cutting elements for each slit, wherein each cutting element cuts deeper than the previous cutting element. In other words, there are three or more progressive cutting elements for each slit in the major web. The first cutting element cuts the overlaminate, the second cutting element cuts several sheets of the book, and the last cutting element cuts the label web. Additional middle cutting elements may be provided to progressively cut the sheets of the book, depending on the book's thickness.

The continuously moving step separates the multi-up book log into separate booklet labels where the booklet remains unadhered to a label of the minor label web so that the label and booklet can independently conform to a curved surface. Following the continuously moving step, the method further comprises the step of applying the label to a curved surface, wherein the label and booklet can bend independently of each other. The overlaminate includes a first portion adhered to the booklet, a second portion adhered to the label, and a hinge portion disposed between said first and second portions. The spine of the booklet is disposed adjacent the hinge portion of the overlaminate. Following the step of applying the label to a curved surface, the method further includes the steps of pivoting the overlaminate to an open position in which the first portion of the overlaminate and the adhered folded booklet is pivoted away from the label. In addition, the overlaminate may be pivoted to a closed position in which the folded booklet can conform to the curvature of a cylindrical container independent of the label.

The overlaminate includes a tab portion which extends beyond the folded booklet. The booklet includes a second fold that is disposed adjacent the tab portion of the overlaminate. The continuously moving step slits the overlaminate, the multi-up book log and the major label web along the same longitudinal line so that they form a common edge.

In a further embodiment, there is provided a method of manufacturing parallel webs containing extended content booklet labels. A major web having a width and a longitudinal direction is conveyed into a slitting station. The major web includes a series of extended content book log labels each extending across the width of the major web. The book log labels are completely pre-trimmed in the longitudinal direction. The major web continuously moves through the slitting station where it is progressively slit along the longitudinal direction to form two or more parallel minor webs. The progressive slitting trims the extended content book log in the width direction to form a series of extended content booklet labels on each of the parallel minor webs. The major web includes a series of major labels each extending across the width of the web and pre-trimmed in the longitudinal direction, where the web further includes multi-up book logs each disposed on each major label. A further step provides attaching the book logs to the label by overlaminating to adhere the book logs to the labels, where the overlaminate is pretrimmed in the longitudinal direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In this application a “booklet” means an individual instructional piece having a cover sheet, a back sheet and at least one internal sheet. A sheet is a piece of paper having two opposed pages. The smallest booklet featuring one cover sheet (2 pages), one internal sheet (2 pages) and one back sheet (2 pages) would have a total of six pages. Additional internal sheets can be added. A booklet with two internal sheets would have a total of eight pages.

Booklets may be formed from one large sheet and one medium sheet by folding the large sheet in half and inserting the medium sheet into the fold. Such a booklet would have three sheets for a total of six pages.

The booklet may be formed by securing sheets and pages together at the binding by adhesive, glue or other suitable connection means. The booklet may have perforations at various locations on different sheets, to provide pages which can be removed from the book.

Booklets may be formed from one large sheet folded multiple times. The simplest example would be one sheet folded in half, and then folded in half again in a perpendicular direction. Such a booklet would have four sheets for a total of eight pages. The large sheet is bound together at the binding during the first folding step so that when the first fold is trimmed off the sheets remain connected together. Booklets with a greater number of sheets/pages may be provided by folding the large sheet additional times.

Booklets may be formed from two large sheets. The simplest example would be two sheets folded in half and then nested together with their fold lines bound together. Such a booklet would have 4 sheets and eight pages. Each additional large sheet added to the book would contribute another 2 sheets and 4 pages. Alternatively, the two large sheets can be folded in half and stacked together with the fold lines bound together to form a so called perfect bound booklet. Again, each additional large sheet added to the book would contribute another 2 sheets and 4 pages.

Booklets may be formed from large sheets that are folded end-over-end, for example folded end-over-end twice to form a ribbon that is three sheets thick. The ribbon in then folded in half perpendicular to the end-over-end folds. Binding adhesive may not be required. The end-over-end folds are then trimmed off to form a booklet with six sheets and twelve pages. If the original large sheet is folded end-over-end three times, the resulting booklet would have eight sheets and sixteen pages. Accordingly the final number of sheets can be calculated by taking the number of end-over-end folds, adding 1, and multiplying by 2. For 4 end-over-end folds, the resulting booklet would have 10 sheets, i.e. (4+1)*2=10.

Booklets may be formed from large sheets that are accordion folded, for example accordion folded twice to form a ribbon that is three sheets thick. The ribbon in then folded in half perpendicular to the accordion folds. Binding adhesive may not be required. The accordion folds are then trimmed off to form a booklet with six sheets and twelve pages. If the original large sheet is accordion folded three times, the resulting booklet would have eight sheets and sixteen pages. Accordingly the final number of sheets can be calculated by taking the number of accordion folds, adding 1, and multiplying by 2. For 4 accordion folds, the resulting booklet would have 10 sheets, i.e. (4+1)*2=10.

The large or medium sheets used to form the booklets are preprinted with indicia before folding. The layout of the printing is designed to provide text in a particular orientation on each page in the folded booklet. In a preferred embodiment, the indicia includes pharmaceutical information about drugs that are packaged with the booklets. The books can be printed by any suitable industrial printing process, for example sheet offset, web offset, flexographic, rotary letterpress, or gravure.

In this application the term “book” refers to a printed article having two or more booklets included therein. The booklets are linearly arranged with a common spine. In addition, a book includes a waste zone in between each adjacent pair of booklets. A book may include a top waste zone disposed above the top booklet. The top waste zone includes the upper edge of the book. The top waste zone may include free sheets and/or folds. A book may include a bottom waste zone disposed below the bottom booklet. The bottom waste zone includes the lower edge of the book. The bottom waste zone may include free sheets and/or folds. By cutting and removing the waste zone(s), the various booklets will be formed from the book. Cutting a top or bottom waste zone that includes folds, will allow the sheets of the resulting booklets to be opened.

The term “multi-up” refers to the orientation of the booklets within the book when the book is disposed onto the web or substrate. The web is a continuous substrate material that is typically wound off a roll and then passes through various manufacturing stations in a longitudinal direction. Therefore, longitudinal is the direction extending along the indefinite length of the web. The width across the web is a direction that is perpendicular to the longitudinal direction. When the book is placed on the web with the booklets oriented one below the other across the width, the book is considered to be multi-up. That is, a discrete longitudinal section of the web contains two or more booklets.

One form of a multi-up book 10 is illustrated in FIGS. 1A-1E. In the drawings, reference numerals having a 6 or 8 prefix, refer to sheets that are used to construct the book. Reference numerals with a 10 prefix refer to the completed book. Reference numerals with a 12 prefix refer to booklets, while reference numerals with a 14 prefix refer to the waste zones. FIG. 1A shows a large sheet 6a and a medium sheet 8a that are combined to form a book 10. Considering the final configuration of the book, sheets 6a and 8a are pre-printed with indicia to create properly oriented text and images for the various booklets that will be part of the multi-up book. Large sheet 6a is folded in half (or twice folded in thirds or additionally folded in other fraction) to form fold 6f. Glue 10e is applied to secure medium sheet 8a to the inside of fold 6f. The resulting book 10 is shown in FIG. 1B. The large sheet now forms cover sheet 10c and back sheet 10b. The medium sheet now forms internal sheet 10a. The resulting book has six pages: the front of cover sheet 10c, the back of cover sheet 10c, the front of internal sheet 10a, the back of internal sheet 10a, the front of back sheet 10b, and the back of back sheet 10b.

Glue for the spine of the books may be selected from various adhesives used in paper converting or corrugated applications that are approved for use in pharmaceutical packaging. Such adhesive may be water-based synthetic resins, for example, WB8147M available from H. B. Fuller of St. Paul, Minn.

The resulting book can be increased in size by adding sheets (to create two additional pages per sheet). For example, to increase to an 8 page book, large sheet 6a can be combined with a further large sheet. The two large sheets can be folded like sheet 6a and nested together with a line of glue at the fold line. Alternatively, the two large sheets can be placed on top of each other and glued together at the spine, in a perfect bound arrangement. To further increase the number of sheets, medium sheets (similar to medium sheet 8a) can be added to form a 10 page book, for example. In this manner, books with increasing number of [paired] pages can be formed by combining 1, 2, 3 or more large sheets and 1 or more medium sheets. In lieu of two medium sheets, one could simply add a folded large sheet.

The book shown in FIG. 1B is fully assembled and as a multi-up book (or log) it contains two or more booklets, each with a complete set of instructions or indicia. To prepare book 10 for use in the subsequent manufacturing steps, it is desirable to tuck in the free edges to streamline the book for further handling. Book 10 is divided into three sections with two fold locations designated as 10x(i) and 10x(ii). The arrow 10y(i) indicates the fold direction as the book is initially folded at first fold location 10x(i). FIG. 1C shows the resulting configuration with a completed first fold 10z(i). The arrow 10y(ii) indicates the fold direction as the book is subsequently folded at second fold location 10x(ii). FIG. 1D shows the resulting configuration with a completed second fold 10z(ii). Note the free ends of the sheets are tucked inside the book so as to avoid interference with the processing and handling equipment. As will be explained in greater detail below, the folded book 10 includes an upper surface 10r that will be adhered to the overlaminate, and a lower surface 10s that will be placed on the web and selectively adhered thereto.

Referring to a perspective view of the folded book, FIG. 1E shows book 10 with two booklets 12b, 12d alternating with a top waste zone 14a, a waste zone 14c and a bottom waste zone 14e.

Multi-up books are an efficient way to print and fold multiple books. The booklet labels described in this application use a single booklet. Booklets for the labels can be produced by forming a book 10 and trimming off the waste zones. The book is also referred to herein as a book log.

The books are made from paper referred to as offset stock having a paper weight between 22# and 60#. The # designation is a measure of paper density measured in pounds per basis ream of 500 sheets of 17″ by 22″ paper. Such paper may be obtained from Twin Rivers Paper Company of South Portland, Me. or Finch Paper, LLC of Glen Falls, N.Y. For example Twin Rivers supplies 22# Custom Plus and 27#, 30#, 35#, 40# Pharmopaque—Regular Finish. Finch supplies 40# Finch Opaque—Wove Finish and 60# Finch Opaque—Vellum Finish. The preferred paper is Twin Rivers 27# Pharmopaque—Regular Finish.

Another form of a multi-up book 20 having 4 sheets and 8 pages made from a single large sheet 16 is shown in FIGS. 2A-2F. In these drawings, reference numerals having a 16 prefix, refer to sheet(s) that are used to construct the book. Reference numerals with a 20 prefix refer to the completed book. Reference numerals with a 22 prefix refer to booklets, while reference numerals with a 24 prefix refer to the waste zones. FIG. 2A shows a large sheet 16a pre-printed with indicia to create properly oriented text and images for the various booklets that will be part of the multi-up book. Large sheet 16a is folded in half to form fold 16f(i). Glue 20e is applied to secure two linear sections of the folded sheet 16a together. As can be most easily seen in FIGS. 2B and 2C, the glue line 20e will form the spine 20d of the book. The sheet is then folded in half again as indicated by arrow 16f(ii). When the two folds are completed, the large sheet 16a forms cover sheet 20c, internal sheets 20a(i) and 20a(ii), and back sheet 20b. The resulting book has eight pages: the front & back of cover sheet 20c, the front and & back of internal sheet 20a(i), the front and back of internal sheet 20a(ii), and the front and back of back sheet 20b.

The resulting book can be increased in size by adding sheets. For example, another one or more large sheet(s) like 16a can be folded and nested within large sheet 16a and/or laid on top of 16a. Using two large sheets like 16a would provide a book with 8 sheets and 16 pages. Alternatively, a medium sheet which is half the size of large sheet 16a can be tucked into the fold and adhered top and bottom with a pair of glue lines similar to 20e. One large sheet and one medium sheet would provide a book with 6 sheets and 12 pages. In this manner, books with increasing number of [paired] pages can be formed by combining 1, 2, 3 or more large sheets and 1 or more medium sheets. In lieu of two medium sheets, one could simply add a folded large sheet.

The book shown in FIG. 2C is fully assembled and as a multi-up book it contains two or booklets, each with a complete set of instructions or indicia. In a subsequent step, the top fold 16f(i) will be trimmed off to allow the pages of book 20 to open and separate from each other. To prepare book 20 for use in the subsequent manufacturing steps, it is desirable to tuck in the free edges to streamline the book for further handling. Book 20 is divided into three sections with two fold locations designated as 20x(i) and 20x(ii). The arrow 20y(i) indicates the fold direction as the book is initially folded at first fold location 20x(i). FIG. 2D shows the resulting configuration with a completed first fold 20z(i). The arrow 20y(ii) indicates the fold direction as the book is subsequently folded at second fold location 20x(ii). FIG. 2E shows the resulting configuration with a completed second fold 20z(ii). Note the free ends of the sheets are tucked inside the book so as to avoid interference with the processing and handling equipment. As will be explained in greater detail below, the folded book 20 includes an upper surface 20r that will be adhered to the overlaminate, and a lower surface 20s that will be placed on the web and selectively adhered thereto.

Referring to a top view of the folded book, FIG. 2F shows book 20 with three booklets 22b, 22d, 22f alternating with a top waste zone 24a, intermediate waste zones 24c, 24e and a bottom waste zone 24g. As mentioned earlier, top waste zone 24a contains fold 16f(i) and will be trimmed off.

Multi-up books are an efficient way to print and fold multiple books. The booklet labels described in this application use a single booklet. Booklets for the labels can be produced by forming a book 20 and trimming off the waste zones. Alternatively, by adjusting the printing and size of the sheets, book logs can be produced with four or more booklets separated by waste zones.

Another form of a multi-up book 30 having 6 sheets and 12 pages made from a single large sheet 26 is shown in FIGS. 3A-2F. In these drawings, reference numerals having a 26 prefix, refer to sheet(s) that are used to construct the book. Reference numerals with a 30 prefix refer to the completed book. Reference numerals with a 32 prefix refer to booklets, while reference numerals with a 34 prefix refer to the waste zones. FIG. 3A shows a large sheet 26a pre-printed with indicia to create properly oriented text and images for the various booklets that will be part of the multi-up book. Large sheet 26 is accordion folded twice in thirds to form folds 26f(i) and 26f(ii). Glue 30e is applied within both folds. Each glue line secures two linear sections of the accordion folded sheet 26 together. As can be most easily seen in FIGS. 3B and 3C, the glue line 30e will form the spine 30d of the book. The sheet is then folded in half again as indicated by arrow 26f(iii). When the three folds are completed, the large sheet 26 forms cover sheet 30c, internal sheets 30a(i) and 30a(ii) and 30a (iii) and 30a(iv), and back sheet 30b. The resulting book has twelve pages: the front & back of cover sheet 30c, the front and & back of internal sheets 30a(i) through 30a(iv), and the front and back of back sheet 30b.

The resulting book can be increased in size by adding folds. For example, another one or a larger sheet like 26 can be accordion folded three or more times to produce four or more panels, respectively. That is the total number of folds of form 26f(i), can be represented by ii, iii, iv . . . n. Where the number of panels would be represented by 3, 4, 5 . . . n+1.

In this manner, books with increasing number of [paired] pages can be formed by an increasing number of accordion folds.

The book shown in FIG. 3C is fully assembled and as a multi-up book it contains two or booklets, each with a complete set of instructions or indicia. In a subsequent step, the top fold 26f(ii) will be trimmed off to allow the pages of book 30 to open and separate from each other. If additional folds are present along the top edge of book 30, they will likewise be trimmed off. Similarly, the bottom fold 26f(i) will be trimmed off along with any additional folds present at the bottom edge of book 30. To prepare book 30 for use in the subsequent manufacturing steps, it is desirable to tuck in the free edges to streamline the book for further handling. Book 30 is divided into three sections with two fold locations designated as 30x(i) and 30x(ii). The arrow 30y(i) indicates the fold direction as the book is initially folded at first fold location 30x(i). FIG. 3D shows the resulting configuration with a completed first fold 30z(i). The arrow 30y(ii) indicates the fold direction as the book is subsequently folded at second fold location 30x(ii). FIG. 3E shows the resulting configuration with a completed second fold 30z(ii). Note the free ends of the sheets are tucked inside the book so as to avoid interference with the processing and handling equipment. As will be explained in greater detail below, the folded book 30 includes an upper surface 30r that will be adhered to the overlaminate, and a lower surface 30s that will be placed on the web and be selectively adhered thereto.

Referring to a top view of the folded book, FIG. 3F shows book 30 with two booklets 32b, 32d alternating with a top waste zone 34a, an intermediate waste zone 34c, and a bottom waste zone 34g. As mentioned earlier, top waste zone 34a contains fold 26f(ii) and will be trimmed off. Bottom waste zone 34e contains fold 26f(i) and will be trimmed off

Multi-up books are an efficient way to print and fold multiple books. The book is part of an efficient process to handle and place one large log onto a web in place of handling and placing several small booklets. In addition, the book log includes waste zones that can be used for glue placement and registration marks that are used during manufacturing and will be removed prior to completion of the labels.

Another form of a multi-up book 40 having 6 sheets and 12 pages made from a single large sheet 36a is shown in FIGS. 4A-4G. In these drawings, reference numerals having a 36 prefix, refer to sheet(s) that are used to construct the book. Reference numerals with a 40 prefix refer to the completed book. Reference numerals with a 42 prefix refer to booklets, while reference numerals with a 44 prefix refer to the waste zones. FIG. 4A shows a large sheet 36a pre-printed with indicia to create properly oriented text and images for the various booklets that will be part of the multi-up book. Large sheet 36a is folded end-over-end twice in thirds to form folds 36f(i) and 36f(ii). Glue 40e is applied within both folds. For example, glue is applied in a line down the center of large sheet 36a perpendicular to the folds 36f. The glue line secures two linear sections of the end-over-end folded sheet 36a together. As can be most easily seen in FIGS. 4B, 4C and 4D, the glue line 40e will form the spine 40d of the book. The sheet is then folded in half as indicated by arrow 36f(iii). Glue line 40e is disposed co-linear to the final fold 36f(iii) which cooperatively form spine 40d. When the three folds are completed, the large sheet 26 forms cover sheet 40c, internal sheets 40a(i) and 40a(ii) and 40a (iii) and 40a(iv), and back sheet 40b. The resulting book has twelve pages: the front & back of cover sheet 40c, the front and & back of internal sheets 40a(i) through 40a(iv), and the front and back of back sheet 40b.

The resulting book can be increased in size by adding folds. For example, another one or a larger sheet like 36a can be folded end-over-end three or more times to produce four or more panels, respectively. That is the total number of folds of form 36f(i), can be represented by ii, iii, iv . . . n. Where the number of panels can be calculated as a function of folds as ii+1, iii+1, iv+1 resulting in the number of panels being 3, 4, 5 . . . n+1. In this manner, books with increasing number of [paired] pages can be formed by an increasing number of end-over-end folds.

The book shown in FIG. 4D is fully assembled and as a multi-up book it contains two or more booklets, each with a complete set of instructions or indicia. In a subsequent step, the top fold 36f(ii) will be trimmed off to allow the pages of book 40 to open and separate from each other. If additional folds are present along the top edge of book 40, they will likewise be trimmed off. Similarly, the bottom fold 36f(i) will be trimmed off along with any additional folds present at the bottom edge of book 30. To prepare book 40 for use in the subsequent manufacturing steps, it is desirable to tuck in the free edges to streamline the book for further handling. Book 40 is divided into three sections with two fold locations designated as 40x(i) and 40x(ii). The arrow 40y(i) indicates the fold direction as the book is initially folded at first fold location 40x(i). FIG. 4E shows the resulting configuration with a completed first fold 40z(i). The arrow 40y(ii) indicates the fold direction as the book is subsequently folded at second fold location 40x(ii). FIG. 4F shows the resulting configuration with a completed second fold 40z(ii). Note the free ends of the sheets (which are opposite spine 40d as shown in FIG. 4D) are tucked inside the book so as to avoid interference with the processing and handling equipment. As will be explained in greater detail below, the folded book 40 includes an upper surface 40r that will be adhered to the overlaminate, and a lower surface 40s that will be placed on the web and remain unadhered thereto.

Referring to a top view of the folded book, FIG. 4G shows book 40 with two booklets 42b, 42d alternating with a top waste zone 44a, an intermediate waste zone 44c, and a bottom waste zone 44e. As mentioned earlier, top waste zone 44a contains fold 36f(ii) and will be trimmed off. If additional top folds are present, they will be trimmed off also. Bottom waste zone 44e contains fold 36f(i) and will be trimmed off. If additional bottom folds are present, they will be trimmed off also.

As discussed above, FIG. 4F shows a multi-up book that is bi-folded in equal thirds to form folded book 40. An alternative configuration is shown in FIG. 5, where the multi-up book is twice folded in unequal sections to form folded book 50. Folded book 50 shows a ramp-up section 50q(i) of double thickness, a center section of triple thickness, and a ramp-down section 50q(ii) of single thickness. The ramp-up and ramp-down sections are useful in certain applications, for example with thicker books. All of the multi-up books described in this application can be folded to include the ramp-up and/or ramp-down sections. As used herein, a ramp section means a section having fewer than all panels present. The ramp sections are located at the leading or trailing edges of the multi-up book. As will be described in greater detail below, the lower section 50s will be placed on the web and remain unadhered, while the upper section 50r will be adhered to the overlaminate. The ramp sections will allow the overlaminate to layer onto the book and web with a smoother transition. That is, the overlaminate can transition off the web to a double thickness, before accommodating the triple thickness. The overlaminate can then transition to a single thickness before re-attaching to the web. As can be seen in FIG. 4F, if book 40 is very thick, gaps may form on either side as the overlaminate transitions from the web to triple thickness and then back down to the web. Books containing ramp sections may be trimmed to form booklets for use in the labels according to the invention.

Multi-up books are an efficient way to print and fold multiple books. The booklet labels described in this application uses a single booklet. Booklets for the labels can be produced by forming a booklet and trimming off the waste zones. Alternatively, by adjusting the printing and size of the sheets and trimming off the folds 36f(i) and 36f(ii), the resulting item 40 can be a single folded booklet.

Referring back to FIG. 5, the upper surface 50r will be adhered to the overlaminate, with all other sheets being free from the overlaminate. The book may be formed with perforation, for example, perforations running in the sheets parallel to the spine of the book. When the booklet is opened, perforation 50p(i) would allow about ⅙ of the sheet to be removed. Such perforations can be included on one or more sheets at similar or different locations. Other perforations 50p(ii) allow about a half sheet to be removed. Where perforation 50p(iii) would allow about 1 full sheet to be removed. The sheet portions that are removed could include coupons, receipts for pharmacists, hand-outs for patients, or other printed or machine-scannable documents. Each booklet could have multiple perforations on one sheet, or several perforations on different sheets. The hand-outs could be similar to each other or different. As can be appreciated, the original large sheets 6a, 16a, 26a, 36a and the medium sheets 8a can be preprinted and perforated to provide indicia and hand-outs in certain orientations and configurations within the individual booklets.

The extended content booklet label according to the invention includes a folded extended content booklet that is secured by an overlaminate to a substrate. The extended content booklet may be formed by various methods as described above. The extended content book log is preferably folded 2 times, so as to enclose the fee ends within the interior of the completely folded booklet. In this manner handling is reduced in that a single book log can be placed on the web to produce 2 or more booklet labels. For example, a 4-up book log can be placed on the web in a single step. A slitting operation then divides the log into four separate booklets. To increase efficiency, the slitting operation is performed as a continuous operation. The web passes through a slitting station at full speed and is progressively slit along the longitudinal direction of the web. In the case of a 3-up book, the major web would be slit four times to form three separate minor webs, and two intermediate waste webs. If the top needs to be trimmed, the major web would be slit five times to form three separate minor webs and three alternating waste webs. In some instances the top and bottom need to be trimmed, as in the case of books formed by folding methods of FIGS. 3A-3F or by FIGS. 4A-4G. In these books the top and bottom need to be trimmed to remove folds that would otherwise hold the upper and lower booklets closed. In this case the major web would be slit six times to form three separate minor webs, and four alternating waste webs.

This continuous slitting operation has a distinct advantage over conventional die cutting. As the book log grows in number of pages and multi-up number, the force required to die cut increases dramatically. For example, a twice folded book log as shown in FIG. 4F is 12 sheets thick plus the thickness of the label and overlaminate. In a 4-up configuration, a die cut must be made through 14 layers at three locations minimum. At the bottom of the die cut stroke, care must be taken to avoid cutting or damaging the release liner. If a different book log is subsequently run, like the 9 sheet book log of FIG. 1D, the die cut pressure must be adjusted to cut through 9 sheets plus the label and overlaminate without cutting or damaging the release liner. Of course, the width of the book log will also effect the amount of die cut pressure needed.

Prior to entering the slitting station, the substrate is referred to as the major substrate, that is, the full width substrate. After the slitting station, there will be two or more parallel narrow substrates, referred to as the minor substrates. The substrate is functionally a web. Prior to the slitting station the web is referred to as the major web, that is, the full width web. Exiting the slitting station are two or more narrow webs, referred to as the minor webs.

The major substrate may be a continuous web with a series of extended content book logs labels adhered thereto in spaced relation to one another. After slitting, two or more minor release liners will be formed as parallel continuous webs. Each minor release liner will include a series of extended content booklet labels.

The substrate is preferably label stock that is adhered to a release liner with adhesive. The major release liner may be a continuous web with a series of extended content book logs labels adhered thereto in spaced relation to one another. After slitting, two or more minor release liners will be formed as parallel continuous webs. Each minor release liner will include a series of extended content booklet labels.

As a broad overview, a web is provided having a series of book log labels which extend across the width of the web. The book log labels are pre-trimmed in the longitudinal direction. The web continuously moves through a slitting station and is progressively slit to trim the book log labels in the width direction to form several narrow webs each having a series of booklet labels.

In one embodiment, the major web consists of label stock strips that extend across the width of the web. The label stock is pre-trimmed in the longitudinal direction. The label strip includes label sections and waste sections corresponding in number and size to the booklets and waste zones of the book. The waste zone of the book logs are glued to the waste sections of the label. An overlaminate is applied to adhere the entire book log to the label sections. The major web is subject to a progressive slitting operation to separate the labels from the waste sections and waste zones. An illustrative example of this embodiment may be seen in FIGS. 6A-6C.

In an alternate embodiment, the major web consists of label stock that is die cut to provide two or more individual labels across the width of the web. The label stock is pre-trimmed in at least the longitudinal direction, that is the label stock is pre-trimmed in the longitudinal direction and the width direction. The individual labels correspond in number and location to the booklets. An overlaminate strip is rolled onto the printed column of the label while the book log is placed onto the booklet placement column. The book log is held in place while the overlaminate is rolled over it. The major web is subject to a progressive slitting operation to separate the waste zones. An illustrative example of this embodiment may be seen in FIGS. 7A-7B.

The web may be chosen from various paper or label stock. In a preferred embodiment, web 600 includes a release liner 600a, and a paper layer 600b coated with adhesive 600c, as shown in FIG. 6B. The release liner 600a is a polypropylene substrate having a thickness between 0.5 mil and 4.5 mils.

Suitable labels include those having between 54# to 60# facestock.

Such label stock is available from Avery Dennison sold under the trademame Fasson®. For example, Avery Dennison supplies 54# semi-gloss facestock (paper) coated with C2500 rubber based adhesive disposed on 40# bleached, calendered kraft stock liner; and 60# semi-gloss facestock (paper) coated with S246 general purpose permanent rubber based adhesive FDA compliant with 21 CFR 175.105 disposed on 40# bleached, calendered kraft stock liner. The preferred label stock is the latter 60# semi-gloss facestock coated with S246 disposed on 40# stock liner.

Glue used to secure the waste zones of the books to the web may be selected from various adhesives used in paper converting applications that are approved for use in pharmaceutical packaging. Such adhesive may be permanent acrylic adhesive, for example, clear, permanent acrylic adhesive S8020 available from Avery Dennison sold under the tradename Fasson®.

FIGS. 6A and 6B illustrate web 600 with three adhesive strips 606a running along the longitudinal direction L of the web. The adhesive strips may be continuous lines of glue, or discrete sections of adhesive that are selectively deposited or printed onto the label sections 604b. The adhesive strips 606a are located in the waste rows passing across the cut sections and the label sections 604b. The waste zones 14a, c and e of the books will align with the adhesive strips 606a to temporarily hold the book in place on the label sections 604b. It should be noted that booklets 12b and 12d will not be adhered to the web. On the right label section 604b, a book 10 has been adhered in place along the right edge of label section 604b. Label section 604b is divided into a printed column 604c and a booklet placement column 604d. The left side of the drawings shows a book 10 being aligned for placement on to the next available label section 604b. A registration mark 604r may be printed on a waste section of label, to indicate to a scanner the distance to the leading edge of the next label section 604b. This process allows a two-up or multi-up booklets to be placed on the web in one step.

Next the web with adhered books passes to a laminating station where a continuous laminate having a similar width to the web, is fed from a laminate spool and applied over the web and books. The laminate is may be opaque, translucent or transparent. If an opaque laminate is used, it may be pre-printed with indicia. In such a case, the laminate would need to be applied to the label section and book in registration. In a preferred embodiment the laminate is transparent without indicia. Accordingly, the indicia 602a and any printing on the upper facing surface of the book can be seen through the laminate. The laminate has a lower surface covered with adhesive and protected by a release liner. The release liner is peeled away and discarded as the laminate dispenses off the laminate spool. A press roller insures that the laminate is closely adhered to the web as it encounters the bumps going from the flat web to the books adhered to the label sections. The continuous laminate may be cut in between each labels section.

The laminate may also be provided as pre-cut sections of laminate 640a. FIG. 6B. shows a bottom view of the release liner 600a with continuous adhesive strips of glue 606a passing over the label sections 604b. Pre-cut sections of laminate 640 will secure booklets 10 to the label sections. Laminate section 640a may include a laminate tab 640e which adheres to the release liner. Laminate section is pressed in place by a laminate roller 640r. For example, two laminate rollers can be aligned with booklets 12b and 12d, thereby avoiding the adhesive strips 606a.

Suitable laminate includes facestock between 0.8 to 1 mil thick coated with adhesive disposed on a liner. Suitable laminates are available from Avery Dennison sold under the tradename Fasson®. For example, Avery Dennison supplies 0.8 mil polypropylene facestock coated with clear, permanent acrylic adhesive; and 1 mil clear printed—treated polyester coated with S8020 clear, permanent acrylic adhesive disposed on 40# bleached white glassine liner. The preferred laminate is the latter 1 mil clear printed—treated polyester coated with S8020 clear, permanent acrylic adhesive disposed on 40# bleached white glassine liner.

Next the laminated web passes through a slitting station 650, as shown in FIG. 6C, where four parallel slits 650a-d are made through the entire web, dividing it into five parallel minor webs. Two of the parallel minor webs contain a series of booklet labels. Three of the minor webs contain waste material carried by the waste liner 600w that is removed. By simultaneously slitting the entire web the laminate, books and labels, and release liner have a clean, common uniform edge.

Two webs of release liner 600a with completed labels 700 are shown exiting the slitting station 650. The D label 622d is shown with an exaggerated thickness to illustrate that the remaining sections of paper 600b have now been removed from the release liner 600a of web 600. The 12d booklet is adhered to the right side of label 622d. The remaining laminate 640 overlies label 622d and extends further off the right side thereof to form laminate tab 640e. Laminate 640a is adhered to the exposed (left) portion of label 622d and is adhered to booklet 12d. Each row of booklet labels may be wound onto individual spools, providing several one-up label rolls.

FIGS. 6A and 6B show the right edge of book 10 aligned with the right edge of label section 604b, that is in the booklet placement column 604d. In an alternate embodiment the right edge of book 10 is spaced from the right edge of label section 604b to create a label tab. The label tab can be unitary with label section 604b, or a perforation can be provided between the label tab 604t and label section 604b. The perforations can be formed within the first die cutting station. This label tab would extend underneath laminate tab 640e, that is the label tab would reside between laminate tab 640e and release liner 600a. An example of the label tab 604t is shown in dotted line in the bottom, center label of FIG. 6C. According to this embodiment, the laminate tab 640e would be peeled from and re-adhered to the label tab, rather than the plastic bottle 800 (as shown in FIGS. 8A-C). If the label tab is perforated, it can be removed if the user prefers to have the laminate tab adhere to the container.

In FIGS. 6A-6C the label sections 604b are provided in strips extending across the Width—W of the web 600. The label sections are pre-trimmed and properly spaced in the Longitudinal Direction—L of the web 600. Pre-cut sections of laminate 640a, approximately the same size as the label sections, are provided to hold the booklets to the labels after the adhesive strips have been slit away. FIG. 7B shows an alternate arrangement where the label web 600 is die cut to form two or more individual labels across the Width—W of the web. Strips of laminate are provided to hold the book log to the labels. Again, the label sections are pre-trimmed and properly spaced in the Longitudinal Direction—L of the web 600.

An alternate arrangement is shown in FIG. 7A which represents a continuous label and overlaminate solution. The web 600 of label stock travels to the right at speed Y. Book logs 10 are placed on the label stock at appropriate locations. A continuous web of laminate 640 is placed over the logs and labels and is pressed down by laminate roller 640r. In order to provide the appropriate longitudinal spacing between labels, the labels will be cut and moved to another release liner. Knife roller 650a cooperating with support roller 660c cuts across the entire Width—W of the web down to the first release liner 600a(i). For example, the knife roller 650a is shown with two blades 660b that are placed on a roller. Based on the diameter of the roller, one blade or more than two blades may be provided.

The labels sections 604b which are now completely separated from each other will be transferred off the first release liner 600a(i) as it passes around a small diameter drop-off roller 662. The label sections 604b will then be transferred onto second release liner 600a(ii) as it passes around pick-up roller 664. If the labels are 2 inches long in the Longitudinal Direction—L, and it is desired to separate the labels by 0.2 inches, the second release liner will move at a linear speed that is ten percent faster than the first web. For example, the second web 600a(ii) is indicated as moving at a speed of 1.1 times as fast as Y, the speed of the first release liner 600a(i). The properly spaced book logs that are adhered to the overlaminate are now ready for the slitting station. Note that the labels, books and overlaminate are completely pre-trimmed in the Y (longitudinal) direction of the web. All that remains is to slit the major web into a series of parallel minor webs. Each minor web will be wound onto a separate roll. In this manner, multiple rolls bearing a series of spaced apart booklet labels can be manufactured without having to handle the small booklets. In other words, large sheets can be printed and folded to form large book logs which are easily handled and secured to the web. By the time the web encounters the slitting station, the book are already secured to the web, and once slit into booklets, can be rolled up without needing to handle the small booklets. The cutting elements in the slitting station are stationary. The web moves through the slitting station at full speed. For each slit to be made, the web encounters a bank of aligned cutting elements. Each cutting element within a bank is set to slit progressively deeper. Since a separate bank of cutting elements is provided for each slit, 4 or 5 slits can be made just as easily as 2 or 3. In other words, the slitting of the web is continuous operation where the web moves at full speed and is slit into several parallel minor webs using its forward motion to force the overlaminate and book logs against the cutting elements. The cutting elements are fixed and spaced from a stationary platen. Both the cutting elements and the platen do not move. The progressive slitting operation involves continuously moving the web in between the stationary bank of cutting elements and the stationary platen.

In an alternate embodiment, the label web 600 is fed past a die cut station, where a die cutter 670 moves in a reciprocating movement 670a to form die cuts 604a shown in dotted line. The matrix of waste laminate 640w is peeled away from the release liner, wound and discarded. A series of two or more label sections 604b remain arranged across the Width—W of the release liner 600a. The labels are oriented with printed column 604c on the right hand side. A pre-cut section of laminate 640a is adhered to the printed column 604c. One section of laminate is applied across the Width—W of the web to cover all the labels. A book log 10 is placed on the booklet placement column 604d and held in place while the overlaminate is folded down. Note the labels and overlaminate are pre-trimmed in the Longitudinal Direction—L.

FIG. 7C shows the web of FIG. 7B feeding into slitting station 650. At each discrete section of release liner web 600a there are two or more label sections 604b. In this instance a three-up label arrangement is shown. A single book log 10 extends across all the labels in the Width—W direction. The book log 10 is secured to the label by an overlaminate. The book log is divided into booklets 34a, 34c and 34e. The booklets are separated by waste zones 32b, 32d. Additional waste zones may be provided at the top in the Width—W direction, and/or the bottom in the Width—W direction. As the release liner web 600a passes through the slitting station 650, a series of blades slit the web in the Longitudinal Direction—L. The slits 650a-d form two ribbons of waste liner 600w, that includes the waste zones 32b, d from the book log 10 and the waste laminate 640w that covers each waste zone 32 from the book log 10.

The slitting station 650 includes a series of blades for each slit, i.e. 650a. The blades cooperate with a support with the web passing between the blades and the support at full speed. For example, three or more blades are provided for progressively forming each slit 650a. The slitting station is well suited for thick book logs, for example, a book log with at least three sheets, that is, double folded to present nine sheets thick. The book logs are sandwiched between a label and overlaminate. The first blade slits the overlaminate and a few pages of the book log. The second blade slits the majority of the remainder of the pages. The final blade slits the label, if present, and the release liner. The completed labels 700 may be wound onto individual reels forming a series of labels arranged in a single row along the release liner. When die cutting, a single die is forced through the material. As the thickness of the material increases, so must the force on the die. In addition, if 4 booklets are being formed, more force is required than if 2 booklets were being formed. The slitting operation utilizes a separate bank of cutting elements for each slit. Therefore, doubling from 2 slits to 4 slits does not increase the force on any given bank of cutting elements, since banks would be used instead of 2. In addition, each bank is adjusted to have three or more cutting elements. For thicker books, 5 or 6 cutting elements could be provided in each bank. The first cutting element would slit the overlaminate, the next 4 or 5 would progressively slit pages of the book, and the last would slit the web.

The completed labels 700 from FIGS. 6C and 7C are peeled off the release liner and the label 622d is adhered to a container. FIG. 8A shows label 622d adhered to a cylindrical plastic bottle. The section of overlaminate where it transitions from label 622d to booklet 12d forms a hinge 700a. The hinge holds booklet 12d so that label 622d can freely conform to any radius container. In other words, label 622d can be adhered to the container without interference from the multiple pages of booklet 12d.

Referring now to FIGS. 8A, 8B and 8C (collectively referred to as FIG. 8), there is shown completed extended content booklet labels. FIG. 8 shows a series of one label being adhered to a container, then fully closed, then in the process of being opened. The web may wrap around a peel edge to release the completed label. As the label begins to separate from the web, a bottle is introduced. A roller 810 rotates clockwise while pressed against the bottle which rotates counter-clockwise. As the label is progressively adhered the pages within the booklet can shift and slide without effecting the smooth application of the label to the curved surface. Often in prior art booklet labels, the booklet is adhered to the label. This arrangement ties the overlaminate, booklet and label together. When this ensemble has many pages or bends around a small radius, the outer pages need to travel a further distance than the inner pages. Since all components are tied together, the ensemble will crease. According to the invention, the label can adhere to the container while the booklet and laminate are free to independently conform to the containers radius. Thus, the booklet and label are being pressed against the container at the same time, but are free to shift and slide without interference from the other.

After label 622d is completed adhered, the roller then arrives at the laminate tab 640e. The laminate tab wraps the booklet around the bottle and adheres to the bottle in a location that is totally independent from the label, as shown in FIG. 8B. Accordingly, one label configuration can be used on bottles with different radii. In addition, booklets of different styles, sizes and thicknesses can be used in a standard manufacturing set up. The laminate tab is self adjusting to enclose booklets of any thickness and securely hold them closed until needed. Thus, the laminate tab can adhere to the container closer or farther from the label. If label tab 604t is included, as shown in FIG. 8C in dotted line, it will extend beyond the edge of booklet 12d. When laminate tab 640e is wrapped towards the bottle it will adhere to label tab 604t.

The bottle with enclosed booklet as shown in FIG. 8B is ready to be packaged, shipped and sold. When the booklet needs to be accessed, the laminate tab 640e is peeled away from the bottle, pivoting at hinge 700a to carry the booklet away from the bottle, to a configuration shown in FIG. 8C. If the laminate tab is large or uses very strong adhesive, it may be desirable to reduce the holding strength to facilitate peeling the tab from the bottle. For this purpose, stripes of release material may be printed on the tab. The print area can be adjusted to determine how much adhesive will remain on the tab, thereby controlling the adhesive strength. The booklet can be unfolded at the two fold locations 10x(ii) and 10x(i). The user is presented with 6 or more pages of information, with all pages connected together at spine 10d. For certain applications, perforations may be provided. For example, a portion of the front page may be ripped off at perforation 50p(i). An entire page, e.g. the back page, may be ripped off at perforation 50p(ii).

FIG. 8C shows the spine section 900s adhered to the overlaminate 640a, with middle section 900m and free edge section 900f being unadhered. The booklet could also have its free edge section 900f adhered to the overlaminate. For example, the last page of the booklet within free edge section 900f could be adhered to the overlaminate as shown in FIG. 8D. In this configuration, the free edges 900e would be disposed adjacent the hinge 700a of the overlaminate. In the event the label is used on a flat surface, or a surface curving perpendicular to the bottle shown in FIG. 8A-8C, the booklet could be secured to the overlaminate in an alternate orientation. For example, FIG. 8E shows the booklet with its free edge section 900f opening in a lateral direction from overlaminate 640a (and the substrate/label). As a further embodiment, the free edge section 900f could be adhered to overlaminate 640a with the spine section 900s opening in a lateral direction with respect to the overlaminate (and the substrate/label). For the orientation of FIG. 8A-8D the booklet opens in a longitudinal direction with respect to the overlaminate (and the substrate/label). Other orientations are possible, and would be facilitated if the substrate and overlaminate were provided with angular edges, for example, partial or full hexagonal or octagonal shapes.

The key features of the booklet product according to the invention are a booklet compactly folded, ideally with two or more folds with the free edges tucked inside. The booklet shall remain unconnected to the substrate or label. The overlaminate being adhered to the substrate/label and to the folded booklet. The overlaminate having a hinge portion to pivot the booklet away from the container/substrate/label so that the booklet can be unfolded to allow the pages to be opened.

While various forms of manufacturing books and booklets have been shown and described, it should be understood that additional configurations may be provided within the scope of the application. For example, books with a greater number of pages may be provided. Books having two or more booklets contained therein may be included. Books with different fold locations and directions may be provided. Additional steps, or steps executed in different order are included within the scope of the invention. For example, adhesive and the release liner can be applied to the web before or after the labels are printed. Book logs, overlaminate and labels can be processed in different order or by alternate methods to provide book log labels that are completely pre-trimmed in the longitudinal direction before encountering the slitting station.

Claims

1. A method of manufacturing an extended content booklet label, comprising the steps of: primary parallel folding sheets to form a spine of a multi-up book log;overlaminating the multi-up book log with an overlaminate to a major web having a longitudinal direction so that the spine is oriented perpendicular to the longitudinal direction of the major web; andcontinuously moving the major web passed three or more longitudinally aligned cutting elements, wherein each cutting element cuts deeper than the previous cutting element for progressively slitting the major label web and overlaminated multi-up book log in the longitudinal direction only to form two or more minor webs.

2. The method of claim 1, wherein following said primary folding step, the method further includes: further parallel folding the multi-up book log to form a secondary fold parallel to the spine.

3. The method of claim 1, wherein the multi-up book includes free sheet ends opposite the spine and wherein following said primary folding step, the method further includes: further parallel folding the multi-up book to form two secondary folds that are parallel to the spine to enclose the free sheet ends within the log.

4. The method of claim 1, wherein the web has a width direction perpendicular to the longitudinal direction and wherein the overlaminate and multi-up book log are pre-trimmed in the longitudinal direction.

5. The method of claim 1, wherein the major web comprises a major label web having a release liner and paper stock adhered to the release liner, wherein the overlaminating step includes overlaminating the multi-up book log with an overlaminate to the paper stock.

6. The method of claim 5, wherein the web has a width direction perpendicular to the longitudinal direction and wherein the overlaminate, multi-up book log and paper stock are pre-trimmed in the longitudinal direction.

7. The method of claim 5, wherein said overlaminating step includes overlaminating a series of multi-up book logs with a continuous overlaminate web to the paper stock.

8. The method of claim 5, wherein said overlaminating step includes overlaminating the multi-up book log with sections of overlaminate which are pre-trimmed in the longitudinal direction to adhere the log to the paper stock.

9. The method of claim 5, wherein the first cutting element cuts the overlaminate, the second cutting element cuts several sheets of the multi-up book log, and the last cutting element cuts the major label web to form two or more minor label webs.

10. The method of claim 9, wherein said continuously moving step separates the multi-up book log into booklets and wherein the booklets remains unadhered to a label of the minor label web so that the minor label web and the booklet can independently conform to a curved surface.

11. The method of claim 10, following the continuously moving step, the method further comprises the step of applying the label to a curved surface, wherein the label and booklet can bend independently of each other.

12. The method of claim 11, wherein said overlaminate includes a first portion adhered to the booklet, a second portion adhered to the label, and a hinge portion disposed between said first and second portions.

13. The method of claim 12, wherein the spine of said booklet is disposed adjacent the hinge portion of the overlaminate.

14. The method of claim 13, wherein following said step of applying the label to a curved surface the method further includes the steps of pivoting the overlaminate to an open position in which said first portion of said overlaminate and said adhered folded booklet is pivoted away from the label; andpivoting the overlaminate to a closed position in which said folded booklet can conform to the curvature of a cylindrical container independent of the label.

15. The method of claim 5, wherein the overlaminate includes a tab portion which extends beyond the folded booklet.

16. The method of claim 5, wherein said booklet includes a second fold that is disposed adjacent the tab portion of said overlaminate.

17. The method of claim 9, wherein said continuously moving step slits the overlaminate, the multi-up book log and the major label web along the same longitudinal line to form a common edge.

18. A method of manufacturing parallel webs containing extended content booklet labels, comprising the steps of: conveying a major web having a width and a longitudinal direction into a slitting station, wherein the major web includes a series of extended content book log labels each extending across the width of the major web which are pre-trimmed in the longitudinal direction; andcontinuously moving the major web through the slitting station and progressively slitting the major web along the longitudinal direction to form two or more parallel minor webs, wherein the progressive slitting trims the extended content book log in the width direction to form a series of extended content booklet labels on each of the parallel minor webs.

19. The method of claim 18, wherein the major web includes a series of major labels each extending across the width of the web and pre-trimmed in the longitudinal direction, wherein the web further includes multi-up book logs each disposed on each major label.
