Abstract
Tab material which is wrapped tightly around an edge of a sheet is adhered flat to both faces of the sheet. The sheet is passed through a printer, and indicia is printed on both sides of a tab material fold line on at least a portion of the tab material on one of the faces. Then, the tab material portion is released from that face, folded onto itself on the fold line, and the end of that portion is re-adhered to that face but closer to the sheet edge. Thereby, the folded tab material portion extends out from the edge and has indicia printed on both sides thereof to define a tab. Pursuant to one embodiment, a series of these tab material portions line that face along the edge, separated from one another by die cut lines. The user can then select the portion to be released from the face, folded onto itself and its end attached to the face to define an outwardly extending tab at the desired place anywhere along the edge. Should the desired location of the tab change, the end of the tab defining portion can be detached, the portion unfolded and reattached flat against the face. Another portion at the desired new tab location along the edge can then be released, folded and its end attached to the face to define the new tab. Pursuant to another embodiment, a plurality of smaller end products are defined by microperforation lines on the sheet. Each product abuts an edge of the sheet and wrapped tab material is provided for each. Indicia is printed on each of the tab materials, the end products are separated from the rest of the sheet by pulling along the microperforation lines, and the tab material for each is released, folded and re-adhered. Thereby, a plurality of printed tabbed cards, such as flip-file cards, are formed.
Description




BACKGROUND OF THE INVENTION




The present invention relates to tab sheet and flip-file card assemblies and methods for forming tabbed sheets, dividers or cards with the desired indicia printed on the tabs thereof.




A number of brands of software are available for causing laser, ink jet and other printers or copiers to print the desired indicia directly on tabs of dividers. However. the tabs of these dividers extend approximately one-half inch out from the divider sheet edge, which causes printer feeding problems. Where the body of the sheet has a width of 8-½ inches, the one-half inch wide tab makes the effective sheet width nine inches. Unfortunately, many standard printers or photocopiers can only accept rectangular sheets whose widths do not exceed 8-½ inches.




Also, when tabbed dividers are fed in the portrait direction of the divider sheet using multipurpose or cassette trays into ink jet, electrophotographic or laser printers, the dividers tend to skew as they enter the printer. This skewing occurs because the tabs, by sticking out from the edge of the body of the sheet, do not provide full continuous contact of each divider to the paper guide of the (multipurpose) printer tray. Additionally, since the paper guide is much shorter than the divider itself. the last few tab positions do not contact the paper guide; specifically, the fourth and fifth tabs of a five tab set and the fifth through eighth tabs of an eight tab set do not contact it. When these dividers are fed into the printer, the tabs can catch causing the dividers to not feed straight into the printer.




SUMMARY OF THE INVENTION




Directed to remedying the problems in the prior art, disclosed herein is an improved user-printable divider sheet or page with one or a series of reconfigurable tabs. Thin tab material is wrapped tightly around the edge of a divider sheet and adhered flat against both faces of the sheet. It thereby does not add significantly to the width or thickness dimensions of the sheet and obstruct feeding of the sheet into the printer.




The tab material is selected to accept and display clearly and cleanly indicia which is printed thereon by the printer, as desired by the user. After the indicia has been printed on the tab material on the first face and the sheet removed from the printer, the tab is formed. To form the tab, the tab material is released from the first face (but not the second face of the sheet). Then the released material is folded over onto itself and the distal end attached to the first face. Preferably the tab material is preformed with a fold line on the sheet first face side thereof and (the same) indicia is printed on both sides of the fold line. Then with the released tab material folded on the line to form the outwardly extending tab, the indicia is provided on both sides thereof, easily visible on both sides of the tabbed divider sheet




The tab material can be provided the length (or a substantial portion thereof) of the sheet edge on the first and second faces thereof, and divided into segments on the first face along the edge. Indicia can be printed on each of the segments, and each can be selectively released, folded and attached to form separate printed tabs. The segment selected will be at the desired location of the tab along the edge. Should tab needs change, the tab can be disconnected and that segment reattached in the original tab material position on the first face. If desired, another segment can be released, folded and attached to form a tab at a different location on the sheet edge.




That is, according to a preferred embodiment tie entire, for example, an 8½×11 inch, sheet (or other printable media) which is passed through the printer or copier forms the end product, for example, a tabbed divider sheet. Pursuant to another embodiment, the sheet after the printing operation on its tabbed material(s) is divided into separate smaller end products. They can be separated along perforation, substantial cut or through-cut lines, or a combination thereof. These lines are preferably preformed; that is, the sheets are provided to the user with the separation lines preformed therein defining the outlines of the smaller end products. At least one of the edges of the products can be conveniently defined by one or more edges of the sheet, for example at the sheet corner.




Tab material units are attached, as described above, to each of the sheet portions of the sheet, in an unfolded condition and flat against one face of the sheet. When the sheet is subsequently passed through the printer or copier, the desired indicia is printed on each of the tab material units, preferably on both sides of the score lines thereof. The printer or copier can be programmed to print the same or preferably different indicia on each tab unit on the sheet.




After the sheet has passed through the printer or copier and the indicia printed on the tab material units, the sheet is separated into its smaller end product units. Each is separated by pulling or tearing along its separation lines. After separation (or less preferably before), the tab material unit is released from the first face of the sheet, folded on the score line and reattached as described previously. Thereby, a plurality of (smaller) products, each with its own outwardly-extending tab with indicia printed on both tab sides, can be formed from a single sheet. One preferred configuration of these products is a flip-file card or ROLODEX card with the two slots along a bottom edge for fitting onto the rings of a flip-file card holder. The tab material can be attached at different locations along the top edges of the cards, to stagger or offset them from those of adjacent cards, to provide for easier reading and card access.




Other objects and advantages of the present invention will become more apparent to those persons having ordinary skill in the art to which the present invention pertains from the foregoing description taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION




Referring to the drawings, a number of embodiments of the present invention are illustrated. One preferred embodiment is shown in

FIG. 1

by tab sheet assembly


50


positioned in a feed tray


54


of a printer shown generally at


58


. The printer


58


can be an ink jet, electrophotographic or laser printer. An example of a preferred printer


58


is the Laser Jet III printer available from Hewlett Packard.




Tab sheet assembly


50


includes a main body sheet


62


. Sheet


62


preferably comprises paper, such as paperboard, cover stock, or Bristol paper available from manufacturers such as Champion or International paper. The paper is 0.004 to 0.011 inch thick, is an 8-½ by eleven (or thirteen or fourteen) inch rectangle (or is International A


4


size) and has a weight of 100-230 grams per square meter. Holes


66


can be provided near the binding edge


70


for securing the sheet


62


in a ring binder (not shown) or the like. The binding edge


70


can be reinforced by lamination with a strip of high strength plastic film (not shown) such as polyethylene terephthalate adhesively attached therealong.




A strip of flexible sheet material or tab material


74


is wrapped around the opposite edge


78


of the sheet


62


. The material


74


is preferably based on an opaque plastic film, such as polyethylene terephthalate (e.g. Mylar™) having a thickness of 0.002-0.004 inch, which is coated with a composition such as those taught by Rettker et al., U.S. pat. No. 5,407,234, suitable for being printed thereon by common desktop printers, such as (ink jet or laser electrophotographic) printer


58


. A repositionable or releasable adhesive


82


, such as UR-1 adhesive available from Avery Dennison, releasably attaches the material


74


to the first or rear face


86


of the sheet


62


. A permanent pressure sensitive adhesive


90


, such as P-9 adhesive available from Avery Dennison, attaches the material


74


to the second or front face


94


of the sheet


62


. In lieu of the repositionable adhesive


82


, a permanent adhesive


98


such as the P-9 adhesive, applied to the flexible sheet material


74


with a coating


102


to facilitate release applied to the sheet


62


can be used, as shown in

FIG. 3



a


. (While a “permanent” adhesive cannot be separated from the underlying paper sheet without tearing the fibers of the paper, a “releasable” adhesive can. A releasable adhesive also does not leave an adhesive residue.)




In other words, the flexible sheet material


74


wraps around the edge


78


of the divider sheet


62


, extending onto the front face


94


of the sheet. The reinforcing material


74


is continuous along the front face


94


. It is subdivided according to one preferred embodiment, however, along the back face


86


into segments


106


by die cuts


110


which extend through the film


74


, but not into the sheet


62


, as shown in

FIG. 6



a


, for example. That is, these cuts


110


extend perpendicular to the edge


78


of the sheet


62


and across the full width of the material


74


and divide the material into segments


106


. A score line


114


, parallel to edge


78


, divides the segments


106


into front and rear panels


116


,


118


to facilitate subsequent folding in a later formation step.




The consumer using commonly available software, such as Word available from Microsoft, causes the desktop printer


58


to print indicia


120


,


122


on specific segments


106


of the material


74


on the back face


86


of the sheet


62


. One, some or all of the segments


106


may be printed, as shown in FIG.


2


. Following printing, the user releases the desired segment


106


by peeling it off from the sheet


62


. He then rotates it towards the front face


94


and folds it on the score line


114


. The end


130


of the segment


106


is reattached with the repositionable adhesive


82


to the back face


86


proximate to the edge


78


, as shown in

FIG. 5. A

tab


134


extending out from the edge


78


of the sheet


62


is thereby formed with properly oriented indicia


120


,


122


on the front and rear tab faces.




As shown in

FIG. 5

, the panels


116


,


118


adhere to each other to form a double-thickness tab


134


. The portions of the tab material


74


adhesively attached to the front and rear faces


94


,


86


of the sheet


62


stabilize the tab


134


against pivotal motion.




Although the reinforcing film or tab material


74


is normally much thinner than the base sheet


62


, it may be desirable to indent the base sheet underneath the film, by approximately 0.002 inch. This is to compensate for the thicknesses of the film


74


, to thereby achieve a more or less uniform thickness profile in the assembly


50


prior to printing to facilitate printability. The indenting can be made with the following process: prior to cutting the paper into sheets it is passed between a pair of rollers shaped so as to impress an indentation of the desired depth into the paper in a continuous fashion at the desired position relative to the edge of the page on one or both faces of the web.

FIG. 7



a


is a perspective cross-sectional view through a tab such as shown by line


5





5


in FIG.


4


.

FIG. 7



b


is similar to

FIG. 7



a


but shows an indented embodiment of the invention with the indented area shown by reference numeral


140


.




Using the present assembly


150


, indicia


120


,


122


which later appear on both sides of the tab


134


advantageously can be printed in a single pass through the desktop printer


58


. This is because both sets of indicia (that which will appear on the front and back of the tab


130


) are printed on the same side or face of the assembly


50


, as can be understood from

FIG. 23

, for example.




Unlike pre-cut divider tabs, all tab positions are alike prior to printing. This eliminates the need to possess and select any particular tab position.




The user can “reposition” the tab


134


by releasing the section from the adhesive, unfolding it and reattaching it flat against the body face


84


as shown in

FIG. 6



a


, and unfolding and tab forming another section as shown in

FIG. 6



b


. The same indicia can be printed by the printer


58


on all segments as shown, or different indicia can be printed on each, as shown in FIG.


2


. That is, if needs change and the tab is needed in position #


6


instead of #


3


, then tab #


3


is deconstructed using the repositionable adhesive and tab #


6


is formed, as can be understood by comparing

FIGS. 6



a


and


6




b


. This is in lieu of printing up a new sheet with tab #


6


printed. Color coding and other visual indexing cues, as known to those skilled in the art, can also be used to provide further user convenience.





FIGS. 8



a


and


8




b


show an alternative assembly embodiment


150


. Rather than a single blank strip of material


74


with a series of tab positions along the edge, assembly


150


is a more conventional position-specific design. A page or sheet


154


with a single “shoulder cut” tab construction


158


made using a similar printable reinforcing film releasably attached to the sheet and after a printing operation to print indicia


162


,


164


on opposite sides of score line


168


thereon is shown in these figures. The tab is then released, folded and reattached as shown in

FIG. 8



b


and similar to assembly


50


.




Again, by releasing, rotating, folding and reattaching, a sturdy tab, attractively printed on both faces thereof can be created by the consumer using common personal computing and printing hardware and software. This locates the fold at the tab and provides for superior rigidity by anchoring the tab through the “feet” attached to both faces of the page.




The printed tabbed end products, such as a tabbed index sheet, include the entire sheet


62


. However, another embodiment of this invention includes only a portion of the sheet as the end product. That is, and referring to

FIGS. 9-12

, after the sheet


200


has been passed through the printer or copier (


58


), a portion


204


of the sheet to which the tab material


208


is attached is separated away from the rest of the sheet. The tab material


208


is then partially released, folded and reattached similar to the process as described previously to form the printed and outwardly extending tab


212


. (Alternatively, after printing, the sheet portion


204


can be separated after the tab


212


has been formed.)




More than one of these smaller end products


204


can be formed from a single sheet


208


, and a preferred smaller end product is a flip-file or ROLODEX type card. Referring to

FIG. 9

, four of these flip-file (small end product) cards


204


,


216


,


222


,


226


are shown defined on a single sheet


208


.




Two of the cards (


204


and


216


or


222


and


226


) abut opposite (portrait) ends of the sheet


208


, and the cards at each end abut one another. Perforated lines


230


in the sheet


208


define the portions of the card perimeter not coincident or defined by the sheet edges. A separate tab material


208


,


234


,


238


,


242


is provided for each card


204


,


216


,


222


,


226


, the tab material being wrapped around the corresponding edge of the sheet


200


and adhered flat to both sheet faces. The portion of the tab material on one face of the sheet is divided by a (score) line


246


,


250


,


254


,


258


. Indicia


262


,


266


is printed on both sides of the line by passing the sheet


200


through a printer or copier. That tab material portion is then released, folded and reattached, as previously described, to form an outwardly extending tab


212


, with printed indicia


262


,


266


on both sides thereof.




The printable media (


200


) can be a sheet of paper such as ten mil thick cardstock available from Simpson Paper Mill in Pomona, Calif. The paper sheet


200


can have a thickness of preferably between six or seven and twenty mils, and a weight of between sixty and one hundred fifty pounds. Alternatively, the sheet can be a fifty-seven pound vellum bristol, approximately 7.5 mil thick, such as that available from Wausau or Champion, or ninety pound index paper, approximately seven mil thick, such as that available from International Paper.




The microperforations or perforation lines


230


consist of cuts which vary in size from 0.0125 to 0.0135 inch and which are separated by ties that vary in size from 0.0045 to 0.0050 inch. Thus, there are between fifty-three and fifty-nine perforations per inch, with about fifty-six perforations being an average therebetween. However, it is also within the scope of the invention for the perforations of line


230


to be only thirty-five perforations per inch, or in the range of from thirty-five to fifty-nine perforations per inch.




After the printing operation but preferably before this tab forming procedure, the card(s) is (are) separated from the rest of the sheet


200


. By pulling along the perforation lines


230


(and thereby) breaking the ties, the card separates out easily, quickly and accurately. Each of the four cards


204


,


216


,


222


,


226


is separated out and its tabs formed. The remainder of the sheet


200


can be discarded, if desired. As seen in the drawings, bulbous shaped slots


270


,


274


are formed (by the perforation line


230


in the edge of the card opposite to that of the tabs). These slots


270


,


274


are for fitting, in a known manner, the cards onto a ROLODEX type of ringed file (not shown).




Other numbers, shapes and arrangements of flip-file cards defined on the sheet can be provided as would be apparent to those skilled in the art. Each card should preferably abut a sheet edge so that the tab material can be wrapped around the sheet edge and adhered to both faces of the sheet. Instead of flip-file cards, other smaller end products can be formed from a single larger sheet, as would be apparent to those skilled in the art.




From the foregoing detailed description, it will be evident that there are a number of changes, adaptations and modifications of the present invention which come within the province of those skilled in the art. However, it is intended that all such variations not departing from the spirit of the invention be considered as within the scope thereof as limited solely by the claims appended hereto.
