. T s l nt onf la '0 t d f d n an seve ing books and the like, andfh'as for one object to make it possible to increase the versatility "of p'rinting press equipment by printing two up and binding sidewire or patent fbound books one-half size, wherein two pages are printed simultaneously side by's'ide on the same 'sheet and "wherein subsequently, either before 'or after "separationthe pages are cut apart and separately bound. Ordinarily, 'when a "signature is assembled and' a plurality of signatures are'broug'ht together in a gathering machine, the signatures are bound together by side'wire binding or. patent binding "and the book lis thereafter trimmed. Under ordinary circums'tances, the binding, whether it be side'wire 'or patent, is placed along the left hand side of the book as you look down limit, and the book then fgoeso'n through the processes for'final delivery. Under these circumstancea thebinding' of the signaturesinto abook takes place alongfone side, and when the book is trimmed, it isre'a'dy for distribution.

This invention involves ,first;printing ,on each sheet of the signature two bookpage s where thelines of type are parallel instead of perpendicular to'the'fold line. Then the ,book or assembly of signatures will'be stitched,'preferably by'sidewirestitching, as they-lie flat,'the stitch being fat thefold, but. each sheet has'bn it two :pages of the book instead of one. The purpose of stitching at the signature is to hold the book together for further manipulation. Once this has been done, the book will be rotated through an angle of ninety degrees with the stitching at the head or at the foot of the page as the case may be. Then the book is cut apart between the pages, the sidewire binding being still left at the foot or at the head of the two pages. Then one book will be fed forward, the remaining book will come down into line with the first one, and then the successive books will be fed through the stitcher and into the covering machine. Before the books reach the covering machine, they will be trimmed, preferably on the three sides but, in any event, on the side along which the first stitching was applied. Thus, the original stitching is really a phantom or disposable stitch, being there for the sole purpose of holding the book together until it can be severed, stitched in the proper place, and covered.

The sequence of covering and severing the two books may be varied. The books might be cut apart and then stitched and then covered, or they might be stitched and covered before they are cut apart. The essential point is that, after the book has been assembled by the proper stitching before or after covering, the two books will be severed. If desired, the head and foot may be reversed in the two books. In that case, the covers might be applied simultaneously, and then after the cover has been applied, one book would have the first page up and the other book would have the last page up. The cover can be severed or cut apart just as the books are, as part of the trimming operation.

It is convenient to hold the signatures together to form a book by stitching. This might be sidewire stitching, or

saddle stitchingor clampsjor'pins might be used. An v nt lQf' Q l i iby chin ,iflha since. he oo must be; trimmed any way, trimming discards the phantom bindingor holding means', the on1y loss, being fa possible 'slight increase in the 'amountf of paper removed and the necessity of twosu'ccessive stitching toperations.

The invention is illustrated nior'ebr 'le'ssfliagr'animati- C ll nf' acc m ny r n s. he i I have shown three'possible variations, all having the 's'ame general "characteristic, "namely; that the book {is originally bouhd'orjstitched or held along'onejside, the head or foot'side' of the printing, is then manipulated sothattwo sides of'the signatures or 'book'will jbe bound. The two sides 'will"'be separately covered and before or "after" such bindingand covering, the two books will be cut apart and theforiginal stitching discarded.

Like parts are indicated by likecliaracters throughout the specification anddrawings. v

Referring first'toFigure l, stationAis a plan view of'the printed material asit will appear in thegathering machine stand, it being understood'that'this printed material includes a plurality of signatures, arranged one on top 'of'the other, 'the 'signat'ur'es being separately folded along the line 1, this'beingthe usual'fold of the signatu're. In this case, the fold is along the foot of the book. This assembled .book is then fed into "the inachine trough atst'ati'on B, beingstitched along thefline 2, adjacent the fold andlying flat. 3 indicates the drive chain anddthe pin which propels the book along the trough. At station C, the book contacts a fulcrum pin 5, andis'rot'ated through an angle of niiiety degree's'int'o the position shown at station D. There, the two books may be cut apart along the line 6. We have now separated the books into books A and books B, both books being identically arranged. Book B will then be carried forward in station E. Book A will be pushed down into line with the carrying chain and will follow book B in station E, then as each successive book passes along the trough, each one is separately stitched as at 7. The books go on into the covering machine, are covered in the usual manner and, at station F, are trimmed, the trim cutting 01f the stitching 2 and the edges, shown in dotted lines, and leaving the stitching 7 along the broader edge of the book, namely: the left-hand side as you open the pages.

Referring now to Figure 2, station A is the same as in Figure 1 except that, in this case, the two books are invented head to foot as indicated, folded in exactly the same Way. They then go down into the trough of the machine at station B, are stitched along line 2--2, contact the fulcrum pin or stop 5, to be flipped around through an angle of ninety degrees, to enter station D, but here-- unlike Figure 1, the books are not cut apart. One book is stitched as at 8 and so, now, both books are stitched along one side, the head and foot, and one book is stitched along one side. Then, in station D", the two books are rotated through one hundred eighty degrees, and the top book is stitched at 8. The book then enters station F, being held by the clamp 10, is presented to the gluing roll at 11, and covered in the usual way. The book is then released, enters station G, is rotated one hundred eighty degrees into the carrier clamp of the second carrying machine, which works just as in station F to cover the opposite book. The book then enters station H,

where the two books are cut apart as at 6 and the three sides are trimmed or, if desired, the head and foot are first trimmed and then cut apart for the finish operation.

The turning or flipping of the book can be accomplished by any of the suitable available book handling mechanisms now in common use and not here illustrated in detail. In Figures 1 and 2, I have illustrated a situation where the book, as it goes through the stitching, covering and gluing method, is generally vertical.

Figures 3 and 4 show a modified arrangement of the method of Figure 2. In this case, the book, having left station D, enters station I, being stitched at 8 and 2 as before. Here, the book is horizontal. It passes between hold-down rollers 110 and is presented to edgewise glue applicator rollers 12, and then is covered in the covering machine. In this case, the book 13 at station E is provided with a one-piece cover 14in the previous exemplica-tion, there were two covers, one for each side. This cover will be wrapped around the book by any suitable means, which forms no part of the invention, and the book and cover will then be cut apart along the line 15.

In Figure 4, the book 13 is presented to the vertical rollers 12 with the cover hold-down rollers 11 holding the book against the glue roller. The glue pump 16 will discharge glue through the duct 17 and nozzles '18, against the roller, the doctor blade 19 will insure a proper level of glue, and the remaining glue will be returned to the pump.

It is important that where in the past it has been customary to print a plurality of pages in the signature where the fold line was perpendicular to the line of type in the column, in this invention we propose to increase the capacity or the availability of the press by first printing the pages or columns with the lines of type parallel to the fold line. Then we stitch the phantom or expendible stitches or binding along the fold line merely for the purpose of holding the assembly together so that we can thereafter rotate the assembly through an angle of ninety degrees in the plane of the sheet, after which the pages are bound together by binding perpendicular to the lines of type, that is-perpendicular to the phantom binding 4 after which either as before or in addition to the trimming action, the phantom or expendible binding is cut away and the separate books may be separated before or after the binding perpendicular to the line of type is applied.

We claim:

1. The method of binding books which includes assembling a stack of signatures, each having a plurality of parallel printed pages arranged side by side, head to head and foot to foot, binding the signatures together on a side parallel to the printed lines by disposable stitching rotating the signatures through an angle of ninety degrees, cutting the signatures apart between adjacent pages to form separate books, aligning the separated books each held together by the disposable stitching, one book behind the other, then binding each book along an edge perpendicular to the printed lines, and then trimming to remove the disposable stitching.

2. The method of binding books which includes assembling a stack of signatures, each having a plurality of parallel printed book pages arranged side by side, head to foot and foot to head, binding the signatures together on a side parallel to the printed lines by disposable stitching, rotating the signatures through an angle of ninety degrees, binding the signatures along opposite edges, perpendicular to the printed lines, cutting the signatures apart between the pages to form separate books and then trimming to remove the disposable stitching.

3. The method of binding books which includes assembling a stack of signatures, each having a plurality of printed book pages arranged side by side, binding the signatures together along one side parallel to the printed lines by a disposable stitching, rotating the signatures through an angle of ninety degrees, binding the pages together along lines, associated with each of the book pages, perpendicular to the disposable stitching, trimming the book and discarding the disposable stitching.
