Definitions

  • the present invention is directed to index sheets that are directly printable by machines such as ink jet printers. It further is concerned with tabbed sheets having fold-over binding edges for feeding into copiers and printers for printing operations thereon. Additionally, it relates to constructions of index divider sheet assemblies, processes of manufacturing them and methods of using them.
  • a popular index divider product that is printable by laser printers is the
  • An adhesive peel-off strip is adhered to the backside of the sheet along the tab edge and behind the tab of the DIRECT PRINT product.
  • the strip defines a straight edge perimeter for the product, improving feeding of the product into and/or passing of the product through a printer or copier.
  • the strip is then peeled off of the sheet after the printing operation and disposed of.
  • This product is disclosed in U.S. Patents 5,743,566 ('566) (Hunter et al.) and 5,792,297 ('297) (Hunter et al.). See also, U.S. Patents 5,558,454 (Owen) and 5,836,710 (Owen).

  • the DIRECT PRINT product can thereby be fed in a portrait direction into laser printers, and the peel-off strip creates a rectangular sheet article that provides a continuous edge to run through the printer.
  • the peel-off strip When it is fed into tabloid-size ink jet printers that are designed to print eleven inch by seventeen inch sheets in a landscape orientation, it is fed binding edge first. This insures proper feeding because if it were fed peel-off strip edge first, the tab edge may catch in the printer.
  • peel-off strip For some of the tabloid-size laser printers when the product is fed in the landscape direction, peel-off strip last, the peel-off strip helps the printer correctly sense the edge of the sheet.
  • the edge of the sheet would be sensed about one half inch early, and once the sensor is triggered the printer does not print, and thus will not print on the tab.
  • these printers are the HP 4V, 5 SI and the Mopier printers from HP.
  • the DIRECT PRINT product When the DIRECT PRINT product is fed in the portrait direction from feed trays in many ink jet printers, the sheets are not reliably picked up and fed into the printers. This is particularly true for the HP DeskJet 500C, DeskJet 1200C, DeskJet 1600C and Lexmark printers, and also the Canon Bubble Jet printers and Epson Stylus Color printers. These feed trays have corner separation tabs, which have a height of about one-quarter inch; more specifically, they are about three- sixteenths inch wide and one-quarter inch deep. The tabs are provided to separate the top sheet off of the rest of the stack for individual feed into the printer. Unfortunately, the DIRECT PRINT product hangs up at its folded-over flap on these clips or tray corner tabs of ink jet printers.
  • an improved index divider sheet assembly is disclosed herein.
  • the assembly similar to the prior art product has a main body sheet having a tab extending out of a tab edge thereof.
  • a binding edge flap is folded (on a score line) over onto the body of the sheet along a binding edge opposite to the tab edge, and held in the folded-over position with releasable adhesive.
  • a peel-off strip is attached to the body along the tab edge and extending out therefrom to a distance slightly beyond that of the tab. The strip thereby "squares" off the tab edge, so that it is straight with no protrusions.
  • the strip assists the proper functioning and printing of the printer on the divider sheet.
  • the strip is peeled off of the divider sheet by the user after the printing operation.
  • the binding edge strip is reinforced with a reinforcing strip.
  • the binding edge strip is provided for securing the sheet together with other sheets in a book-like arrangement.
  • One way of doing this is to form binder ring holes in the strip; another way is to provide a series of small rectangular holes for a comb binding system; and a third way is to glue (with heat-activated adhesives) the strips to similar strips on similar sheets and to document sheets in a stack in a thermally bound report.
  • a disadvantage of these strips is that they extend the effective width of the sheet. They extend it about an inch, which makes the sheet too wide to be fed in a portrait direction into most printers and copiers. Accordingly, the strip is folded over onto the body of the sheet and held there with releasable adhesive, as mentioned above. Then after the sheet assembly has been fed into and passed through the printer or copier, the flap is unfolded to a flat orientation with the divider sheet.
  • the flap has notches cut out (either die cut or hole punched) of opposing end corners with a thin "leg" formed at the corners and along the flap fold line.
  • the legs are narrower than the width of the body portion of the flap.
  • These thin legs which fit under the corner clips in the printer/copier feed trays, allow the assemblies to be individually picked up and fed off of a stack of same in the feed trays into the printer/copier.
  • another definition of the invention is a laser printer feed tray with the corner clips and one or a stack of these assemblies (with the fold-over flap which has the thin legs) in the tray.
  • the present assembly can be fed in a portrait direction into an ink jet printer. It can also be fed in a landscape direction into that printer. However, it would be fed binding edge first and the legs may help reduce stiffness of the corners.
  • the legs may also help the divider assembly feed out of a laser printer cassette tray.
  • the depth of the notch may be any depth greater than 3/16 inch, and preferably is 3/8 inch.
  • the width should be such that a thin area (1/16 inch nominal) is left to the outside of the score line. This extra material allows for the accurate folding of the sheet in the fold-and-glue machine discussed below. Although there should be a two-ply area along the edge, the thinner it is the better.
  • the two-ply area should be substantially narrower than the width of the corner separation tabs (less than 3/16 inch) to facilitate feeding of the assembly into a printer or copier.
  • the notch cut and leg form a single thick area that reduces the overall stiffness at the corner.
  • the double-thick area along the edge provides a smooth edge to slide over the corner tabs. If the product were notched to the edge, the interface between the single and double thickness would likely tend to catch in the printer. Furthermore, the extra material allows for easier folding of the binding edge.
  • the assembly can be manufactured using a nine-and-a-quarter inch wide roll of paper coated with an ink jet receptive coating, with a hydrophobic backside coating for moisture stability and to enable release of the adhesive strip. Also, the roll of paper can be uncoated on the back side to facilitate release of the adhesives. (The release coating is used if the paper is not properly moisture balanced and therefore curls.)
  • the paper is processed by several in-line steps.
  • One step is that it is calendered to reduce its thickness in the binding area by up to twenty percent.
  • the calendered area is scored vertically down the middle thereof.
  • the paper is turned over and a reinforcing strip of polyester is applied to the flap area.
  • the paper is slit to a nine inch width, the holes are punched, the paper is notch-punched and the paper is sheeted to eleven inches.
  • the polyester strip may be spaced about 1/32 inch from the score (fold) line. Thus, the polyester strip longitudinally coats about half of the thin legs.
  • the sheets are then processed through a tab cutting machine where a patch of ink jet receptive coated MYLAR is applied to the tab side and the tab shape is cut out.
  • the tabbed sheets are then processed through a fold-and-glue machine that applies the peel-off strip to the back side of the sheet, applies a fugitive adhesive to the hole-punched binding edge, folds the binding edge over and laminates the fold together. More particularly, the fold-and-glue machine performs the following manufacturing steps: a first aligner straightens the sheet; the peel-off strip is applied; Swift adhesive is Gravure printed onto the sheet; the flap is held by feeding into a narrowing V-shaped channel; and the binding edge is held in place with pressure rollers while the adhesive dries.
  • Alternative manufacturing processes of the invention include conducting the notching step "off line" in a discrete operation after the reinforcing and hole punching steps. Instead of punching and slitting the notch, it can be die cut. Slitting to size is optional and can be done after the notching step, if desired. Many of the steps in the two paragraphs above can be rearranged, as would be apparent to those skilled in the art. Additionally, the tab need not be MYLAR-reinforced. Thus, the notch cut can be formed in-line with punch die sets on a

The different positions are selected so that a stacked set of different tab position assemblies 100 has the tabs 108 thereof staggered in a known fashion so that all are readable when in a ring binder, for example.
  • the assemblies 100 are collated into respective sets. And the sets are then packaged in a known manner pursuant to step IV(b), as in transparent plastic packaging (not shown) with identifying indicia and instructions printed thereon and/or on a separate instruction sheet (also not shown) which is included in the package together with the set of assemblies (100) and then sealed closed.
  • the packaged sets may then be boxed into cartons and then delivered to the ultimate user 390 through ordinary retail channels.
  • the process steps in the converting press 310 can be varied, for example, by moving the slitting process step 1(f) of FIG. 13 so that it is between the reinforcing strip application step and the hole punching step, as shown by process step 1(c) in FIG. 16.
  • a further alternative to the process of FIG. 13 (and the variation thereon of FIG. 16) is to not perform the notch cutting step 1(d) of FIG. 13 in the converting press 310, but rather to transport the intermediate product to a separate notch cutting machine 400, as shown in block diagram form in FIG. 17.
  • a prefe ⁇ ed separate notch cutting machine 400 stamps the sheet with a plate that has sharp steel rules that cut out the notch shape (similar to a cookie cutter). The two end notches will then be die cut out of the end comers of the flap in the notch cutting machine 400.
  • the intermediate product which is delivered to the notch cutting machine 400 will have been subjected to process steps 1(a), (b), (c), (e), (f) and (g) of FIG.
  • the leg 164 serves an important function in the folding step I ⁇ I(e) discussed above.
  • the fold-and-glue machine 330 has a rail that catches where the score line should be. Thus, if the entire comer of the flap 120 (all of the way to the fold line 124) were notched out, the machine 330 would tend to catch on the top comer of the sheet. In other words, without the leg 164, the comer where the sheet transitions from single thickness to double thickness catches and holds the sheet in the tray 230, preventing it from being fed out.
  • the leg 164 prevents the assembly 100 from catching as it is fed out of the tray 230. That is, the leg 164 provides the printer 234 with a continuous area, making the feed step smoother.
  • the dimensions of the leg 164 are defined in substantial part by the location and dimensions of the comer separation tab or clip 238 in the printer feed tray.
  • the height of the comer tab 238 is about one-quarter inch, so the leg 164 is preferably dimensioned to be a slight distance greater, three-eighths inch, for example.
  • the paper 350 can have a weight of one hundred and thirty grams plus or minus ten grams per square meter. It preferably should be thin enough (less than six or six and half mil) and flexible enough to feed through today's ink jet printers.
  • the back side of the paper 350 should preferably have a fairly rough surface of at least one-hundred and fifty Sheffields or about one hundred and fifty to two hundred Sheffields. Sheets with a fairly rough back surface tend to slip less and thus feed better into printers.
  • the paper may have front and back side ink jet receptive coatings 410, 420 as shown in FIG. 8 (and which are not present in the prior art DIRECT PRINT product). Both sides are coated to prevent product curl.
  • the back side 420 coating can be hydrophobic to assist the release of the water-based fugitive adhesive 122 of the flap 120 and the adhesive 132 of the peel-off strip 128 therefrom. It is made hydrophobic by adding an agent thereto wherein the agent modifies the coating 420 such that it counteracts the hydrophilic nature of the binders in the ink jet receptive coatings and enhances the release of ultraremovable adhesives and fugitive adhesives such as the resins-based PVA adhesive. This deadening agent thereby prevents the adhesives from being absorbed into the sheet and thereby aggressively adhering to the sheet.
  • the paper 350 can come pre-coated with the deadening agent or it can be in-line coated on standard two-sided coated ink jet papers to facilitate release of the adhesives. It is also within the scope of the invention to coat the paper only on one side thereof.
  • the flap 120 is formed separately and from a material different than that of the divider sheet and then attached thereto, such as disclosed in the previously-mentioned PCT publications. Also, the flap 120 can be constructed such that adhesive 266 is not used to attach it to the divider sheet 104 in the folded-over position.
  • the tab 128 is not integral with the sheet but is a separate element which is secured to the sheet 104 before or after the printing operation. Additionally, the tab 128 and/or the binding edge 120 flap can be at an end instead of a side of the sheet.
  • a further alternative is to form the leg 164 by means other than cutting the notch out of the paper, as would be apparent to those skilled in the art from this disclosure.
  • the present notch-cut invention can be applied to laminates, such as thick cardstock, where one calenders or removes some facestock to create the same single-thick, double-thick pattern. It is intended, however, that all such variations not departing from the spirit of the invention be considered as within the scope thereof.

Abstract

L'invention concerne un ensemble de feuillets intercalaires (104) d'index conçu pour alimenter des imprimantes à jet d'encre et similaire en vue d'une opération d'impression sur le corps de la feuille et/ou d'un onglet (108) dudit ensemble (104). Cet ensemble (104) comprend un feuillet intercalaire pourvu d'un onglet (108) en saillie par rapport à un bord et un volet (120) latéral de liaison renforcé (120). Le feuillet intercalaire peut être fabriqué à partir d'une carte copie blanche à couche supérieure réceptrice de jet d'encre. Une glissière (128) le long du bord de l'onglet permet l'alimentation de l'ensemble (104) et le passage à travers l'imprimante en dépit de la présence de l'onglet (108). Le volet (120) est plié sur le corps du feuillet et ainsi maintenu pour réduire la dimension en largeur de l'ensemble (104), de telle manière qu'il peut être amené dans l'imprimante et passé à travers cette dernière. Après le passage à travers l'imprimante, la glissière (128) est enlevée et le volet (120) est déplié. Afin d'améliorer l'alimentation de l'ensemble (104) à partir du bac à papier de l'imprimante dotée de guides d'angle, le volet (120) est fabriqué de manière à avoir des encoches débarrassées des deux extrémités pour définir des sections minces le long de la ligne de pliage (116) et des deux extrémités des coins du volet (120).
