650 Almanor Avenue, Sunnyvale, California 94086, United States of America WILLIAM H. ABILDGAARD and ELMER G. SZANTO Address for Service: Spruson Ferguson, Patent Attorneys, Level 33 St Martins Tower, 31 Market Street, Sydney, New South Wales, 2000, Australia Complete Specification for the invention entitled: "BINDING STRIPS FOR RECTANGULAR HOLE PUNCHED PAPER" The following statement is a full description of this invention, including the best method of performing it known to us SBR/TGK/197W -2- BINDING STRIPS FOR RECTANGULAR HOLE PUNCHED PAPER This invention relates to new and improved binding strips for use with, for example, rectangular holes punched paper, A commonly used binding system initially produced by General Binding Corporation, (herein GBC) includes punches which cut elongated rectangular holes adjacent the spine edge of paper. Another common binding system produced by Velo-Bind, Inc, (herein Velo-Bind) uses plastic strips, one strip having studs fitting through holes in the paper and the other strip, the excess lengths of which are cut and riveted. The holes of the Velo-Bind System are round as are the cross-sections of the studs.

There are a number of advantages of the Velo-Bind system as compared with the GBC system, including the following: The bind is tight.

The book is not as thick at the spine.

The bind is permanent in that sheets may not be inserted and removed 0 without debinding the strips.

o o The strips used with the Velo-Bind system are less expensive than the o strips of the GBC system.

g ao The present invention uses the Velo-Bind system with paper punched with holes compatible with the GBC system. Thus, the customer has the choice of binding rectangular hole paper either with the GBC system or the Velo-Bind system binding elements. Only a GBC type punch is required.

o0OOO, In one broad form the present invention provides a pair of binding 0o strips for use with sheets formed vicinal their spine edges with a 0 '25 plurality of substantially identical holes, said holes being equally spaced apart a distance x and being longitudinally elongated a second distance y, said strips comprising a first strip having a plurality of first studs, S' each having a longitudinal dimension z substantially less than y extending o o therefrom spaced apart from each other a distance ax where a is an integer 000 and at least one second stud aligned with said first studs and having a longitudinal dimension substantially less than y, said second stud being spaced from one said first stud a distance substantially equal to .a 1/2 and at least one third stud aligned with said first studs and having a longitudinal dimension substantially less than y, said third stud being spaced from one said first stud a distance substantially equal to bx 1/2 where h is an integer is different from a and a second strip formed with second holes spaced and dimensioned to receive said studs.

KLN/1594b i 00 0 0 0 0 0000 o 0 00 0 C 000 3 A further broad form of the present invention provides a book comprising a plurality of sheets, each formed vicinal their spine edges with a plurality of substantially identical elongated apertures, said apertures being equally spaced apart a first distance x and being longitudinally elongated a second distance y, a pair of binding strips, a first said strip having a plurality of first studs extending therefrom each having a longitudinal dimension z substantially less than y spaced apart from each other a distance ax where A is an integer and at least one second stud aligned with said first studs and having a longitudinal dimension substantially less than y, said second stud being spaced from one said first stud a distance substantially equal to ax 1/2 and at least one third stud aligned with said first studs and having a longitudinal dimension substantially less than y, said third stud being spaced from one said first stud a distance substantially equal to bx 1/2 where b is 15 an integer which is different from a and a second strip formed with holes ao spaced and dimensioned to receive said studs, said studs extending through said apertures and said holes, said second stud engaging a first short edge of one said aperture, said third said stud engaging a second short edge of another said aperture opposite said first edge, said studs being fixed to said second strip.

A still further broad form of the present invention provides a method of forming a book comprising providing a plurality of sheets each formed vicinal their spine edges with a plurality of substantially identical oo elongated apertures, said apertures being equally spaced apart a first "2 5 distance x and being longitudinally elongated a second distance y, aligning o: said sheets with said aperture in registry, providing a pair of binding a trips, a first said strip having plurality of first studs extending therefrom, each having a longitudinal dimension z substantially less than y °0 spaced apart from each other a distance ax where A is an integer and at 30 least one second stud aligned with said first studs and having a 0 longitudinal dimension substantially less than y, said second stud being spaced from one said first stud a distance substantially equal to ax 1/2(y-z) and at least one third stud aligned with said first studs and having a longitudinal dimension substantially less than y, said third stud being spaced from one said first stud a distance substantially equal to bx 1/2 where b is an integer which is different from A and a second 00 o c 00 f 0 0 0 0 Oo 0000 0 o 0 0 00 000 0000 oo KLN/1594b >1 4 strip formed with holes spaced and dimensioned to receive said studs, inserting said studs through said apertures and said holes, said second stud engaging a first short edge of one said aperture, said third said stud engaging a second short edge of another said aperture opposite said first edge, cutting off excess lengths of said studs and securing said studs to said second strip.

Preferred forms of the present invention will now be described by way of example with reference to the accompanying drawings, wherein: Fig. 1 is an end elevational view of a book in accordance with the present invention prior to cutting and heading the studs, the book being partly cut away to improve illustration of the subject matter.

Fig. 2 is a bottom plan view in accordance with the 0000 000 0 0000 0000 0 0 00 o o 00 0C Ko ioN1 0 00 0 000000 KLN/1594b

Y.

1 present invention broken away in several locations more completely to reveal the construction, Fig. 3 is a sectional view taken substantially along the line 3--3 of Fig. 1; Fig. 4 is an enlarged sectional view taken substantially along the line 4--4 of Fig. 2 showing various stages in the cutting and neading of the studs.

Fig. 5 is a fragmentary view similar to Fig. 3 of a modification, The paper 11 used in accordance with the present invention is punched with a GBC type punch forming elongated .oo. rectangular holes 12 adjacent the spine edge of each sheet.

Holes 12 are of uniform length and are spaced apart a uniform distance The holes 12 are spaced inward from o 0 o, the spine edge a predetermined distance but, the punching a 9 operation sometimes results in such distances varying from the desired predetermined standard, Male strips 13, are fabricated of a plastic which is preferably thermoplastic, One suitable plastic is a semi-rigid polyvinyl chloride, In a preferred embodiment of the invention, such strips are approximately 1/4 inches wide and .070 inches thick, Integral with and depending from the 01 strip 13 at approximately 1-1/8 inch intervals are studs 14 having tapered points 18, The studs are approximately .095 inches in diameter, Various lengths of studs may be used depending on the anticipated thickness of the book to be formed, Stud disneters are indicated in the accompanying drawings as and are uniform, The distance between studs 14 is DI; between studs 14 and 16 D2; between the nearest SD/359P stud 14 and stud 17 is D 3 Thus, as best shown in Fig. 2, when the studs are inserted in the holes 12 of a stack of sheets,the stud 17 engages the right-hand edge of the leftmost hole 12 while the stud 16 engages the left-hand edge of the third endmost stud. The remaining studs 14 are located approximately in the centers of respective holes 12.

Studs 14, 16, 17 are shown round in Figs, 1-3. However, as shown in Fig. 5 the studs 14a, 16a, and 17a may be square or other shape. It is understood, of course, that the dimension must be substantially less than As is apparent from Fig, 2, there are preferably only one-half as many studs 14, 16, 17 as there are holes 12, o 04 S° Since, as has been stated, sometimes the holes 12 are 0000 located at varying distances from the spine edges of the o o paper 11, as best shown in Fig. 3, the strip 13 is formed with an extension 19 toward the spine edge of the book which Sconceals the edge of the paper 11 which might otherwise be 0 9 eo exposed outside the strip 13.

Female strip 21 is formed with regularly spaced holes 0 '204 at intervals corresponding to the spacing of the studs 14.

The two endmost holes in strip 21 are aligned with the studs o 17 and 16. Preferably, each hole 22 is formed on the u underside of strip 22 with a counterbore 23 or a countersink. The female strips are formed with lateral extensions 25 corresponding to the extensions 19 of the male strip 13.

To assist in locating the female strip in the binding machine, which may be any of the machines shown in U.S, patents 3,756,625, 3,800,146 and 3,994,035 or 4,270,970 or other similar machines, a locating hole 24 of a smaller SD/359P -6diameter than the holes 22 is formed to receive a locating pin such as the pin 102 shown in Fig. 11 of patent 4,270,970. This locates the female strip 21 laterally relative to the machine and also insures that the extension is oriented in proper direction. To insure that the male strip 13 is properly located, it will be noted that the end pin 17 is considerably longer than the pin 14 at the opposite end.

Thus, with any of the Velo-Bind machines heretofore mentioned, the female strip 21 is located in proper position, Sheets 11 are positioned on top of the strip 21, 8 Strip 13 is then positioned, the studs 14, 16, 17 passing 0 0 S through the holes 12 in the sheets 11 and the holes 22 in the 0 S strip 21, Stud 17 engages the right-hand end of the leftmost hole 12, Stud 16 engages the left end of the third inmost a o" hole 12. Initially, the points 18 extend well below the strip 21 and pressure is applied in accordance with the S Velo-Bind binding system to the strip 13, compressing the sheets between the strips 13 and 21 (Fig, 4, left-hand end).

The machine then cuts off the excess lengths of the studs 14, 0 a 16, 17, leaving stubs 26 (see middle of Fig. Thereupon the machine forms a rivet head 27 filling the counterbore 23.

o (Fig, 4, right'-hand end).
