Description

THE FIELD OF THE INVENTION

The present invention relates generally to book forming and, more particularly, to a system for forming fold-lines in a book cover prior to binding of a book block with the book cover.

BACKGROUND OF THE INVENTION

In making a book, a book block (i.e., a plurality of sheets of paper) is typically bound with a book cover by a book binder. The book block includes a body of the book having, for example, a table of contents, text, index, etc. Typically, the book cover is one sheet or piece of material cut to a desired size and includes a front cover, a back cover, and a cover spine provided between the front cover and the back cover.

With a conventional book forming system, the book cover is positioned in a book binder and the book block is positioned relative to the book cover such that a spine of the book block is bound with the cover spine of the book cover. As such, the front cover and the rear cover are openable relative to the cover spine. To facilitate opening of the front cover and/or the back cover relative to the cover spine, fold-lines can be provided in the book cover along lateral edges of the cover spine. Unfortunately, conventional systems for forming fold-lines in the book cover are often very complex and not easily reconfigured for processing differing book covers.

Accordingly, a need exists for efficiently forming scorelines in a book cover prior to binding of a book block with the book cover such that precise fold-lines are provided along lateral edges of the cover spine.

SUMMARY OF THE INVENTION

One aspect of the present invention provides an apparatus for forming scorelines in a book cover. The apparatus includes a pair of scoring counter-bars and a pair of scoring tools. Each the scoring counter-bars have a longitudinal axis and a first surface substantially parallel with the longitudinal axis. Each of the scoring counter-bars include a first longitudinal indentation provided in the first surface thereof and each of the scoring tools include a scoring protrusion provided thereon. As such, the scoring protrusion of one of the scoring tools is adapted to engage the first longitudinal indentation of an associated one of the scoring counter-bars.

In one embodiment, the pair of scoring tools includes a pair of scoring wheels. As such, the scoring protrusion of each of the scoring tools is a circumferential scoring protrusion. In one embodiment, the pair of scoring tools includes a pair of scoring bars. As such, the scoring protrusion of each of the scoring tools is a longitudinal scoring protrusion.

In one embodiment, each of the scoring counter-bars includes a longitudinal protrusion provided on the first surface thereof and each of the scoring tools includes a scoring indentation provided therein.

Thus, the scoring indentation of the one of the scoring tools is adapted to receive the longitudinal protrusion of the associated one of the scoring counter-bars and the scoring protrusion of the one of the scoring tools is adapted to engage the second longitudinal indentation of the associated one of the scoring counter-bars.

In addition, in one embodiment, the second surface of each of the scoring counter-bars is substantially perpendicular to the first surface thereof and each of the scoring counter-bars is rotatable about the longitudinal axis thereof. More specifically, each of the scoring counter-bars is rotatable between a first position which facilitates engagement of the first longitudinal indentation of one of the scoring counter-bars by the scoring protrusion of an associated one of the scoring tools and a second position which facilitates engagement of the second longitudinal indentation of the one of the scoring counter-bars by the scoring protrusion of the associated one of the scoring tools.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

The present invention provides a system for forming scorelines in a book cover prior to binding of a book block with the book cover. As such, precise fold-lines are provided along lateral edges of a cover spine of the book cover. One exemplary embodiment of a book cover prepared according to the present invention is illustrated generally at 10 in FIG. 1 A. Book cover 10 includes a cover blank 20 formed from a sheet or piece of material cut to a desired size. In addition, book cover 10 can include a cover image (not shown) provided on cover blank 20 . The cover image can include, for example, images in the form of characters and/or graphics as is well know in the art. Cover blank 20 is made from sheet material such as paper, cardboard, and/or plastic film suitable for forming book cover 10 . Thickness of cover blank 20 can vary according to a desired durability of book cover 10 . Thickness of cover blank 20 can include, for example, 8, 10, or 12 mil.

Cover blank 20 includes a first major surface 22 and a second major surface 23 , and is substantially rectangular in shape. As such, cover blank 20 includes a top edge 24 a , a bottom edge 24 b , and a pair of side edges 24 c . Bottom edge 24 b is spaced from and substantially parallel with top edge 24 a , and side edges 24 c are substantially parallel with each other and substantially perpendicular to top edge 24 a and bottom edge 24 b . Cover blank 20 has a centerline 26 positioned substantially equidistant between and oriented substantially parallel with side edges 24 c . Centerline 26 is also oriented substantially perpendicular to top edge 24 a and bottom edge 24 b so as to bisect top edge 24 a and bottom edge 24 b.

In one exemplary embodiment, cover blank 20 includes a first pair of scorelines 28 and a second pair of scorelines 29 . Scorelines 28 and scorelines 29 , also referred to as hinge or fold-lines, are formed by impressions or creases made in cover blank 20 to help position and facilitate folds of book cover 10 . Scorelines 28 are spaced from and oriented substantially parallel with each other, and scorelines 29 are spaced from and oriented substantially parallel with each other. In addition, scorelines 28 and scorelines 29 are each oriented substantially parallel with centerline 26 of cover blank 20 and extend from top edge 24 a to bottom edge 24 b.

In one exemplary embodiment, scorelines 28 are spaced equidistant from centerline 26 of cover blank 20 and scorelines 29 are spaced equidistant from scorelines 28 and, therefore, centerline 26 of cover blank 20 . As such, scorelines 29 are parallel with and spaced laterally outside scorelines 28 . Thus, scorelines 29 are centered about scorelines 28 . Furthermore, scorelines 29 are inverted relative to scorelines 28 . More specifically, scorelines 28 are formed in first major surface 22 of cover blank 20 and scorelines 29 are formed in second major surface 23 of cover blank 20 .

In one exemplary embodiment, scorelines 28 form spaced longitudinal impressions in first major surface 22 of cover blank 20 and scorelines 29 form spaced longitudinal impressions in second major surface 23 of cover blank 20 . Furthermore, scorelines 28 form spaced longitudinal protrusions on second major surface 23 of cover blank 20 and scorelines 29 form spaced longitudinal protrusions on first major surface 22 of cover blank 20 . As such, scorelines 28 and scorelines 29 define a front cover 12 of book cover 10 , a back cover 14 of cover 10 , and a cover spine 16 of book cover 10 . More specifically, front cover 12 is defined generally between one scoreline 29 and one side edge 24 c , and back cover 14 is defined generally between the other scoreline 29 and the other side edge 24 c . In addition, cover spine 16 is defined generally between scorelines 28 such that cover spine 16 is centered about centerline 26 of cover blank 20 . Furthermore, a front cover spine portion 13 is defined generally between one scoreline 28 and one scoreline 29 adjacent front cover 12 , and a back cover spine portion 15 is generally defined between the other scoreline 28 and the other scoreline 29 adjacent back cover 14 .

In one exemplary embodiment, first major surface 22 of cover blank 20 forms an inner surface 12 a of front cover 12 and an inner surface 14 a of back cover 14 . In addition, second major surface 23 of cover blank 20 forms an outer surface 12 b of front cover 12 and an outer surface 14 b of back cover 14 . Thus, scorelines 28 facilitate folding of inner surface 12 a of front cover 12 (including front cover spine portion 13 ) and inner surface 14 a of back cover 14 (including back cover spine portion 15 ) toward each other relative to cover spine 16 . Scorelines 29 , however, facilitate folding of outer surface 12 b of front cover 12 and outer surface 14 b of back cover 14 toward each other relative to cover spine 16 (including front cover spine portion 13 and back cover spine portion 15 ).

Another exemplary embodiment of a book cover prepared according to the present invention is illustrated generally at 110 in FIG. 1 B. Book cover 110 is similar to book cover 10 with the exception that book cover 10 does not include scorelines 29 . As such, scorelines 28 define a front cover 112 of book cover 110 , a back cover 114 of book cover 110 , and a cover spine 116 of book cover 110 . More specifically, front cover 112 is defined generally between one scoreline 28 and one side edge 24 c , and back cover 114 is defined generally between the other scoreline 28 and the other side edge 24 c . In addition, cover spine 116 is defined generally between scorelines 28 such that cover spine 116 is centered about centerline 26 of cover blank 20 .

In one exemplary embodiment, first major surface 22 of cover blank 20 forms an inner surface 112 a of front cover 112 and an inner surface 114 a of back cover 114 . In addition, second major surface 23 of cover blank 20 forms an outer surface 112 b of front cover 112 and an outer surface 114 b of back cover 114 . Thus, scorelines 28 facilitate folding of inner surface 112 a of front cover 112 and inner surface 114 a of back cover 114 toward each other relative to cover spine 116 .

In use, book covers 10 and 110 bind a book block 30 to form books 40 and 140 , respectively, as illustrated in FIGS. 2A and 2B . A width of cover spines 16 and 116 is based on a thickness of book block 30 . A distance between scorelines 28 , therefore, is also based on the thickness of book block 30 . In one exemplary embodiment, centerline 26 of cover blank 20 coincides with a centerline of cover spines 16 and 116 . As such, scorelines 28 and, therefore, scorelines 29 are centered within cover blank 20 . It is, however, within the scope of the present invention for the centerline of cover spines 16 and 116 to be offset from centerline 26 of cover blank 20 .

One exemplary embodiment of a portion of a scoring apparatus for forming scorelines 28 and scorelines 29 in book cover 10 and scorelines 28 in book cover 110 is illustrated generally at 50 in FIG. 3 . Scoring apparatus 50 includes a pair of scoring counter-bars 60 and a pair of scoring tools 70 . Scoring apparatus 50 includes an operational centerline 51 about which scoring counter-bars 60 and scoring tools 70 are spaced. Scoring counter-bars 60 and scoring tools 70 cooperate to form scorelines 28 and scorelines 29 in book cover 10 and scorelines 28 in book cover 110 . As such, one of the scoring counter-bars 60 is associated with one of the scoring tools 70 and, vice versa.

In one exemplary embodiment, scoring counter-bars 60 each have a longitudinal axis 61 and are oriented substantially parallel to each other. Scoring counter-bars 60 each have a pair of end surfaces 62 (only one of which is illustrated) through which longitudinal axis 61 extends. In addition, scoring counter-bars 60 each include side surfaces 64 extending between end surfaces 62 parallel with longitudinal axis 61 .

As illustrated in FIG. 3 , scoring counter-bars 60 each have a generally rectangular cross-section. Thus, side surfaces 64 include four side surfaces 64 a , 64 b , 64 c , and 64 d oriented substantially perpendicular to each other. As such, side surface 64 a faces scoring tools 70 and side surface 64 b faces centerline 51 of scoring apparatus 50 and, therefore, the other scoring counter-bar 60 . Thus, side surface 64 c is opposite side surface 64 a and side surface 64 d is opposite side surface 64 b . It is, however, within the scope of the present invention for scoring counter-bar 60 to have other multi-side cross-sectional profiles.

In one exemplary embodiment, scoring counter-bars 60 each include an indentation or groove 66 formed in one of the side surfaces 64 , for example, side surface 64 a , and a protrusion or rib 67 formed on the same side surface 64 a . Rib 67 is spaced from and substantially parallel with groove 66 . As such, groove 66 and rib 67 each extend longitudinally along side surface 64 a substantially parallel with longitudinal axis 61 . In addition, scoring counter-bars 60 each include a groove 66 formed in another of the side surfaces 64 , for example, side surface 64 b . As such, groove 66 extends longitudinally along side surface 64 b substantially parallel with longitudinal axis 61 .

In one exemplary embodiment, scoring tools 70 each include a scoring protrusion or rib 72 and a scoring indentation or groove 74 , and scoring counter-bars are each rotatable about longitudinal axis 61 . More specifically, scoring counter-bars 60 are each rotatable between a first position ( FIGS. 3 and 5A ) and a second position ( FIG. 5B ) depending on whether both scorelines 28 and scorelines 29 are to be found in cover blank 20 or only scorelines 28 are to be formed in cover blank 20 . In the first position, scoring rib 72 of each of the scoring tools 70 cooperates with groove 66 of an associated one of the scoring counter-bars 60 and scoring groove 74 of each of the scoring tools 70 cooperates with rib 67 of the associated scoring counter-bars 60 (FIG. 4 A). In the second position, scoring rib 72 of each of the scoring tools 70 cooperates with groove 68 of the associated scoring counter-bars 60 (FIG. 5 B).

In one exemplary embodiment, scoring counter-bars 60 and scoring tools 70 are jointly adjustable laterally as represented by arrow 52 in FIG. 3 . More specifically, one of the scoring counter-bars 60 and an associated one of the scoring tools 70 are adjustable in a direction substantially perpendicular to longitudinal axis 61 . It is within the scope of the present invention for one of the scoring counter-bars 60 and the associated scoring tool 70 to be laterally adjustable relative to the other scoring counter-bar 60 and the associated scoring tool 70 or for both scoring counter-bars 60 and the associated scoring tools 70 to be laterally adjustable relative to each other. In addition, scoring counter-bars 60 and scoring tools 70 are vertically adjustable relative to each other as represented by arrow 54 in FIG. 3 . It is within the scope of the present invention for both scoring counter-bars 60 to be vertically adjustable relative to the associated scoring tools 70 , for both scoring tools 70 to be vertically adjustable relative to the associated scoring counter-bars 60 , or for both scoring counter-bars 60 and both scoring tools 70 to be vertically adjustable relative to each other.

In one exemplary embodiment, the pair of scoring tools 70 includes a pair of scoring wheels 80 . As such, scoring wheels 80 are generally cylindrical in shape. Thus, scoring rib 72 of each of the scoring tools 70 extends circumferentially around a corresponding one of the scoring wheels 80 and scoring groove 74 of each of the scoring tools 70 extends circumferentially around the corresponding scoring wheels 80 .

In one exemplary embodiment, scoring wheels 80 are each rotatably mounted about an axis 81 and one of the scoring wheels 80 cooperates with one of the scoring counter-bars 60 . Axis 81 is oriented substantially perpendicular to longitudinal axis 61 of scoring counter-bars 60 . As such, scoring wheels 80 are moveable along scoring counter-bars 60 as represented by arrow 56 in FIG. 3 . Thus, point contact is provided between scoring wheels 80 and scoring counter-bars 60 as scoring wheels 80 roll along scoring counter-bars 60 .

In one exemplary embodiment, operation of scoring apparatus 50 is controlled by a controller 58 . Controller 58 controls, for example, lateral and vertical adjustment of scoring counter-bars 60 and scoring tools 70 as well as other operations of scoring counter-bars 60 and scoring tools 70 as described herein.

FIGS. 4A and 4B illustrate one exemplary embodiment of forming scorelines 28 and scorelines 29 in cover blank 20 with scoring apparatus 50 to form book cover 10 . As illustrated in FIG. 4A , one of the scoring counter-bars 60 and the associated scoring tool 70 are spaced a predetermined distance d from the other scoring counter-bar 60 and the associated scoring tool 70 . Predetermined distance d is based on a thickness of book block 30 and is measured, for example, between scoring rib 72 of one of the scoring tools 70 and scoring rib 72 of the other scoring tool 70 .

The thickness of book block 30 is established, for example, by actual or inferred measurement. Actual measurement includes, for example, visual or physical sensing of the thickness of book block 30 . Inferred measurement includes, for example, a count of a number of sheets of paper which form book block 30 . From this count and a known thickness or weight of the paper, the thickness of book block 30 can be calculated. As such, the thickness of book block 30 is communicated to scoring apparatus 50 such that predetermined distance d can be established.

As illustrated in FIG. 4B , cover blank 20 is positioned between scoring counter-bars 60 and scoring tools 70 such that centerline 26 of cover blank 20 is registered to centerline 51 of scoring apparatus 50 . With scoring counter-bars 60 and scoring tools 70 , a predetermined pressure suitable for permanently forming scorelines 28 and scorelines 29 is applied to cover blank 20 . As such, scoring rib 72 of each of the scoring tools 70 cooperates with groove 66 of an associated one of the scoring counter-bars 60 to form scorelines 28 in cover blank 20 . In addition, scoring groove 74 of each of the scoring tools 70 cooperates with rib 67 of the associated scoring counter-bars 60 to form scorelines 29 in cover blank 20 .

As scoring wheels 80 roll along scoring counter-bars 60 , point contact is maintained against cover blank 20 by scoring wheels 80 and scoring counter-bars 60 . As such, pressure is applied to cover blank 20 as scoring wheels 80 roll along cover blank 20 and scoring counter-bars 60 . Thus, scorelines 28 and scorelines 29 are simultaneously formed in cover blank 20 by permanently deforming cover blank 20 under pressure. It is understood that a size and shape of scoring rib 72 and scoring groove 74 of scoring tools 70 and groove 66 and rib 67 of scoring counter-bars 60 can be varied according to a desired profile of scorelines 28 and scorelines 29 .

FIGS. 5A-5C illustrate one exemplary embodiment of forming scorelines 28 in cover blank 20 with scoring apparatus 50 to form book cover 110 . As illustrated in FIG. 5A , scoring tools 70 and scoring counter-bars 60 are spaced vertically relative to each other to permit rotation of scoring counter-bars 60 about longitudinal axis 61 . Accordingly, scoring counter-bars 60 are each rotated about longitudinal axis 61 by, for example, controller 56 such that side surface 64 b of each of the scoring counter-bars 60 faces the associated scoring tools 70 , as illustrated in FIG. 5 B. Thus, side surface 64 c of each of the scoring counter-bars 60 faces centerline 51 of scoring apparatus 50 and, therefore, the other scoring counter-bar 60 .

As illustrated in FIG. 5C , cover blank 20 is positioned between scoring counter-bars 60 and scoring tools 70 such that centerline 26 of cover blank 20 is registered to centerline 51 of scoring apparatus 50 . With scoring counter-bars 60 and scoring tools 70 , a predetermined pressure suitable for permanently forming scorelines 28 is applied to cover blank 20 . As such, scoring rib 72 of each of the scoring tools 70 cooperates with groove 68 of an associated one of the scoring counter-bars 60 to form scorelines 28 in cover blank 20 . Thus, scorelines 28 are formed in cover blank 20 by permanently deforming cover blank 20 under pressure. It is understood that a size and shape of groove 68 of scoring counter-bars 60 can also be varied according to the desired profile of scorelines 28 .

Another exemplary embodiment of a portion of a scoring apparatus for forming scorelines 28 and scorelines 29 in book cover 10 and scorelines 28 in book cover 110 is illustrated generally at 150 in FIG. 6 . Scoring apparatus 150 includes a pair of scoring counter-bars 160 and a pair of scoring tools 170 . Scoring counter-bars 160 are similar to scoring counter-bars 60 of scoring apparatus 50 . In addition, scoring tools 170 each include a scoring rib 172 and a scoring groove 174 similar to scoring tools 70 of scoring apparatus 50 . Thus, cooperation and association of scoring counter-bars 160 and scoring tools 170 is similar to that of scoring counter-bars 60 and scoring tools 70 of scoring apparatus 50 . Scoring counter-bars 160 and scoring tools 170 , for example, are jointly adjustable laterally as represented by arrow 152 and vertically adjustable relative to each other as represented by arrow 154 . Operation of scoring apparatus 150 including, for example, adjustment of scoring counter-bars 160 and scoring tools 170 is controlled by a controller 156 .

Scoring apparatus 150 is similar to scoring apparatus 50 with the exception that the pair of scoring tools 170 includes a pair of scoring bars 180 . Scoring bars 180 each have a longitudinal axis 181 and are oriented substantially parallel to each other and to scoring counter-bars 160 . Scoring bars 180 each have a pair of end surfaces 182 (only one of which is illustrated) through which longitudinal axis 181 extends. In addition, scoring bars 180 each include at least one side surface 184 extending between end surfaces 182 parallel with longitudinal axis 181 . As such, scoring rib 172 of each of the scoring tools 170 extends longitudinally along side surface 184 of a corresponding one of the scoring bars 180 and scoring groove 174 of each of the scoring tools 170 extends longitudinally along side surface 184 of the corresponding scoring bars 180 .

One of the scoring bars 180 cooperates with one of the scoring counter-bars 160 . Thus, line contact is provided between scoring bars 180 and scoring counter-bars 160 as scoring bars 180 are pressed against scoring counter-bars 160 . Forming scorelines 28 and scorelines 29 in cover blank 20 with scoring apparatus 150 to form book covers 10 and 110 is similar to that described in connection with scoring apparatus 50 .

By forming scorelines in book covers 10 or 110 prior to binding of book block 30 with book covers 10 or 110 , scoring apparatuses 50 and 150 ensure that precise fold-lines are provided along lateral edges of cover spines 16 and 116 , respectively. Thus, positioning and facilitating of folds in cover blank 20 is provided.

In one illustrative embodiment, book covers 10 and 110 are formed in a books-on-demand system illustrated generally at 200 in FIG. 7 . Books-on-demand system 200 receives orders for single and/or multiple copies of a book and produces the book on-demand. More specifically, books-on-demand system 200 retrieves an electronic file of the book and then prints and binds a copy of the book.

In one exemplary embodiment, books-on-demand system 200 includes a processing system 210 , a book block preparation system 220 , a book cover preparation system 230 , and a book finishing system 240 . In one exemplary embodiment, processing system 210 includes hardware and software for receiving and processing a book request. Processing system 210 retrieves an electronic file of a book being requested and produces a print command for a body of the book including, for example, a table of contents, the text, and an index, and produces a print command for a cover of the book.
