Abstract

An uncased book, such as shown in U.S. Pat. No. 3,596,929 having end leaves fabricated with pressure sensitive adhesive and protected by release paper is attached to a case of the type having a spine pad also fabricated with pressure sensitive adhesive by the device. A table supports various adjustable members including locators which first gauge the thickness of the uncased book to indicate a case of proper spine width to be selected. The case is placed on the table and centered by use of side and top edge guides. The locators are adjusted so that the spine edge of the uncased book may be guided to contact the center of the spine pad. A guide rod positions the top edge of the uncased book a predetermined distance below the top edge of the case. The uncased book spine now permanently adheres to the case spine. The book covers are closed around the book and the end leaf release paper stripped away, permitting the end leaf adhesive to secure the end leaves to the insides of the covers.

sum anr 4 1 DEVICE AND METHOD FOR CASING BOOKS This invention relates to and improved device and method for casing books. More particularly, the invention relates to apparatus and method for positioning and locating a case (hard cover) for a book and an uncased book in such relationship that the parts may be assembled in permanent fashion employing pressure sensitive material onthe spine of the case which adheres to the spine of the uncased book and pressure sensitive material on end leaves of the uncased'book which adhere to the insides of the covers of the case.

A principal object and advantage of the invention is to reduce the number of operations required to bind an uncased book and to case the book. The labor required is materially reduced and the use of existing bindery equipment is almost entirely eliminated while the deare ordinarily spread out and must be .left in'spread condition while glue dries and while other portions are being completed and assembled. Hence, not only is the amount of labor and equipment greatly reduced by practice of the present invention, buteven the floor space required in a bindery is reduced because of the 2 I FIG. 7 is an enlarged fragmentary plan view showing a step in the assembly of the uncased book to the case.

FIG. 14 is a sectional view through the completed book showing the elements in enlarged scale.

In accordance with the present invention, device 61 is used to assemble uncased book 41 and case 46 as hereinafter appears. Assembly involves a series of steps which are also hereinafter explained The uncased book 41 may be of various types. A preferred type is shown in U.S. Pat. No. 3,596,929. Such uncased book 41 isformed of a plurality of sheets 21 formed with apertures 22 adjacent the spine margins thereof. The uncased book is held together by means of a first plastic strip 26 having integral projecting thermoplastic studs 27 spaced to fit through the holes 22 and a second plastic strip 29 formed with similarly spaced holes 31 preferably having external counterfact that it is not necessary to spread out the book parts the amount of skilled labor required. The operator of the device. hereinafter described does not require extensive training in order to practice the invention.

A principal feature-of the invention is the provision and the uncased book relative to each other. Further, the device provides means for attachment of the uncased book to the spine of the case and the end leaves to the insides of the covers rapidly and conveniently.

Other objects of the present invention will become apparent upon reading the following specification and referring to the accompanying drawings in which similar characters of reference represent corresponding parts in each of the several views.

In the drawings:

FIG. 6 is a fragmentary end elcvational view of a portion of the structure.

i of rapid and convenient means for-locating the cased bores in which rivetheads 33 are formed on the severed. ends of studs 27 by passing a hot knife through said studs spaced beyond said second strip and then moving the hot knife toward the second strip to form rivet-likeheads on said studs. End leaves 23 are provided which fit on the top and bottom of the stack of sheets 21, the spine marginal edges of the end leaves 23 being apertured and receiving the same studs 27 which securethe sheets 21 to the

strips

26, 29.

One of the features of the present application is the use of pressure sensitive adhesive 36 on at least a portion of each end leaf 23. Initially, such adhesive 36 is protected from contact with other objects by release paper 37. Release paper 37, as conventionally manufactured, is ordinary Kraft paper which is coated with polyethylene on both sides so that the paper does not absorb solvents or moisture and'the polyethylene coating is stable. At least the side of the release paper to which the adhesive is applied is coated with a silicone material to facilitate stripping.

Adhesive 36 is usually an acrylic, crossdinked acrylic, nitrile rubber or other polymer which is initially dissolved in a solvent as commercially available. A coating between 4 and 6 mils thick is applied to the'silicone coated surface of the release paper 37 and then the solvent is driven off by drying in an oven so that the adhesive layer 36 is about 1 mil or less in thickness. Such release paper 37 coated with adhesive 36 is then laminated to the end leaf 23 and rolled so that the adhesive 36 sticks to the end leaf 23. The fabrication of the end leaf 23, adhesive 36 and release paper 37 is an adaptation of general commercial practice in the pressure sensitive adhesive art.

In a preferred form of the invention adhesive 36 is not applied over the entire area of release paper 37 or end leaf 23 but terminates at line 42 located at about the locations of

strips

26, 29 in the assembled uncased book. To facilitate stripping of the release paper 37, the latter is folded over at about the location of line 42 and extends back in a folded over portion 38 which projects beyond the outer edge of the cased book in an exposed portion 39 which functions as'a pull tab to strip the release paper 37'from the pressure sensitive adhesive 36, as hereinafter appears.

Case 46 is likewise subject to variation, but a preferred form employs cover material 47 of vinyl, leather or other suitable substance and to the center of the case 46 extending vertically in the completed book is a resilient spine strip 48 which is pressure sensitive on both surfaces and is preferably originally covered by release paper (see FIG. 8) which is stripped off at the commencement of the assembling operation. Immediately to the outside of the strip 48 is a hinge forming area 49 which is the thinnest part of the case. Immediately outside of each hinge forming area 49 are boards 51 of cardboard or similar material. The top and bottom margins of the cover material 47 are folded inward in top and bottom turnins 52 at the top and bottom edges of the book, only partially covering the boards 51. Similarly, on each outer edge an edge turnin 53 of the material 47 is formed and the corners54 are preferably mitered, all as in accordance with conventional case manufacturing operations. Thus',-front and back covers 56 and an intermediate central spine cover 57 are provided. In the ultimate fabrication of the book, hinge creases 58 are formed immediately inward of covers 56 and beads 59 formed immediately inward of the hinge creases v58.

In assembling the uncased book 41 to the case 46, the

spine edge of the uncased book 41 is caused to adhere to the pressure sensitive resilient bind strip 48. The top cover 46 (and the bottom cover as well) are unfinished in that the board 51 is shown partly covered by the turned in top and bottom portions 52 and edge turnings 53. The end leaves 23, by means of adhesive 36, adhere to the insides of the boards 51 and to the portions of the turned in

portions

52, 52 and 53 which are ultimately coveredyThe end leaf 23 thus permanently adheres to the covers 56.

Apparatus 61 comprises a plurality of parts which are mounted on a flat table 62 which is preferably rectangularand is large enough to accommodate the largest case 46 to be handled. To protect the underlying surface, a padding 63 of resilient and preferably skid-proof material is furnished. As is shown in FIG. 1, along the right-hand edge of the table 62 are related pairs of holes 64 which are used to locate the case 46 as hereinafter appears. The right-hand holes 64 are used with larger size cases. Spaced inwardly of holes 64 are left holes 66. In general, the holes 64 may be used with wider books such as books printed on paper 8- /inches in width, whereas the holes 66 may be used to locate cases used with smaller sheets such as are used in stan dard textbooks. Associated. with the pairs of holes 64,

- indicia 93 marked on table 62. As hereinafterappears,

66 are indicia 67 which are used to locate in proper position side edge guide 68 shown in perspective in FIG.

4 and consisting of a piece of generally T-shaped plastic bar with one arm of the T being shorter than the other.

Guide 68 has integrally molded depending pins 69' which fit into pairs of

holes

64 or 66. The bar is oriwidth).

Along either side of the back edge of table 62 is a bracket 71, each bracket having upstanding apertured lugs 72. Threaded rod 73 fits through the 'ap'erturesinlugs 72. Preferably, the opposite ends ofrod 73 are oppositely threaded. On one end is a knob 76 and on the opposite end a cap 77. Knob 76 is used to rotate the rod 73. Mounted above and between lugs 72 on either side are brackets 78 which themselves have upstanding threaded apertured outer lugs 79 in threaded engagement'with rod 73 and apertured but unthreaded inner lugs 81. Thus as the knob 76 is turned, the brackets 78 move inwardly or outwardly relative to the center of table 62 in equal amounts but in opposite directions. Each bracket 78 has a forward extension 82 which extends forwardly and inwardly. Extension 82 has upstanding apertured lugs 83 which receive guide rod 84 which is parallel to rod 73. Rod 84 is fixed to the rightmost lug 83 as viewed in FIG. 1 as by welding, but slides in the apertures in the left side lugs 83 so that rod 84 does not inhibit inward and outward movement of the brackets 78 but merely maintains them in parallel.

'Fixed for movement with each of the brackets 78 as they move inwardly and outwardly and also as they pivot about rod 73 are locators 86 which are fabricated of rod stock. Each locator has a straight section 87 whichis parallel to the centerline of table 62. The upper end of each rod 87 as viewed in FIG. 1 is formed with an outwardly turned portion 88 which is welded or otherwise secured to the underside of the inner edge of extension 82 of bracket '78. The forward end of rod 87 is bent in an outwardly turned forward front end 89 which is relatively short and which terminates in a rearwardly'outwardly slanted side 91, the rearward end of which is also welded or'otherwise secured to bracket 78 adjacent its outer edge. As is best shown in FIG. 1, the rod sections 87 are parallel to each other at all times and the locators 86, as best shown in FIG. 3, lie in a common plane at all times, although said plane may pivot about the axis of rod 73.

Connected to the right-hand end of the right-hand bracket 78 is a pointer 92 which indicates a plurality of the locators 86 are used to gauge the thickness of the uncased book 41 to be assembled. Such thickness is indicated by the pointer 92 relative to the indicia 93. Various sizes of cases 46 are used depending upon the size of the uncased book, the different sizes being differentiated bythe width of the flexible spine cover 57. Thus, with thinner uncased books 41 narrower spine covers 57 are employed. The width of the spine cover 57 determines the overall width of the case 46 when it is laid flat on table 62 as is shown in FIG. 8. The side edge guide 68 is positioned by selection of the

proper holes

64, 66 so that the case 46 is accurately centered relative to table 62, 'ormoreprecisely, is accurately centered relative to the gap between the rod sections 87.

Further, by way of location of the case 46, there are three short pins 96 and one long pin 97 fixed to table 62 along the back edge thereof and positioned so that they do not interfere with pivoting of the locators 86 or the brackets 78. The function of the

pins

96, 97 is to act as a stop for the rearward movement of the case 46 as it is pushed back with the top edge tangent to said pins. Preferably, the pin 97 is elongated so as to assist in closing of the book as a next to final step in the assembly of the case to the cover, as hereinafter appears. It should be observed that rod 84 is slightly forward relative to pin 96 when the locators 86 are in down position. This is best shown in FIG. 9. Pin 96 (or 97) limits rearward movement of case 46 (i.e., movement to the right as viewed in FIG. 9) while rod 84 limits rearward movement of the uncased book 41. It is desirable that the top edge of the cover of the completed book be slightly higher than the top edge of the sheets 21 of which the uncased book 41 is formed. The location of rod 84 and pins 96, 97 insures this desirable relationship.

ASSEMBLY OF BOOK TO CASE sizes of case 46 to be used/The side edge guide 68 is then installed in a pair of

holes

64 or 66 corresponding to the size of the case which has been indicated and which has been selected and oriented for proper page width. As has heretofore been explained, the holes 64 are used with 8- /2 inch X l 1 inch sheets 21, while the holes 66 are used with the narrower sheets of textbook size paper. The locators 86 are then pivoted backward to the position shown in FIG. 8 or they may be pivoted 180 or all the way back.

The properly selected case 46 is then placedon the table 62 as best shown in FIG. 8 with its right-hand edge against the side guide 68 and with its top edge against the

ends

96, 97. In such position the case 46 is accurately centered relative to the gap between the 10- cators 86. The release. paper is then stripped exposing the pressure sensitive adhesive on the pads 48 which is located in the spine of the case. Thereupon, the locators 86 are pivoted forwardly until they lie on top of the case 46 (see FIG. 9).

Thereupon, the uncased book 41 is lifted by the operator and inserted in the apparatus 61 taking care that its upper edge engages rod 84 and that its spine slips between the parallel rods 87. As has been mentioned, the upper edge of the book 41 is then slightly below the upper edge of the case 46, as best shown in FIG. 9. Downward pressure on the book 41 causes permanent adherence of its spine edge to the pressure sensitive adhesive 48 of the spine portion 57 of the case 46. The locators 86 are then retracted to up position.

The covers 56 0f the book are then closed. To facilitate accurate closing of the covers, the left cover 56 is folded over and its top edge aligned with the higher pin 97. This assures that the top and bottom covers 56 are parallel. The hinge crease 58 is then manually formed in the top cover by using an implement or the fingers to press the spine portion around the strip 26 and form the bead 59. Thereupon, the operator grips the exposed tab 39 of the release paper 38 and pulls the release paper 38-37 completely away. By pressing downwardly on the top cover 56, the pressure sensitive adhesive 36 on-the top end leaf causes permanent adherance of the endleaf to the inside of the cove'r56.

Thereupon, the book is turned upside down and the crease 58 and bead 59 are formed on the back cover in the same manner as they were formed on the front cover. Finally, the tab 39 is used to pull the

rear release paper

38, 37 of the rear end'leaf away exposing the adhesive 36 which causes permanent adherence of the rear end leaf to the rear cover 56.

The formation of the book is thereby completed. It will be observed that the case 46 is permanently bonded to the uncased book 41 atthree separate locations. These are the adherence of the spine of the book to the adhesive 48, which adhesive also overlaps the

strips

26, 29. The other two locations are on the front and back of the book respectively and are each substantially the same. The outside of each leaf 58 engages pressure sensitive adhesive 36, and the insides of the covers 56 likewise engage said pressure sensitive adhesive.
