Abstract:
Small batches of books are produced. Each book comprises a cover and pages bound within the cover. Covers are produced first. Supply of the covers to a cover storage and supply station along a conveyor line is detected and used to trigger printing of the pages. Thus the average time that blocks of unbound pages are in existence is reduced, which minimizes the risk loss of blocks of pages. Triggering of printing may be adapted dependent on available binding capacity, to reduce average time that blocks of unbound pages are in existence. Carriers are provided on the conveyor line, each for the pages and cover of a respective one of the books. The carriers have a plurality of vertical levels, for pages and cover respectively and wider level is provided for the cover than for the pages.
Abstract:
A method and apparatus for binding a stack of sheets which can be carried out using a conventional perfect binding machine. A stack to be bound is positioned between a pair of end leafs. Molten hot melt adhesive is then applied to the edge of the stack and to the first and second end leafs, preferably using the perfect binding machine. An elongated spine member is then applied to the edge of the stack and is secured by the hot melt adhesive. The elongated spine member is preferably part of a configuration having a form factor that generally matches that of the conventional cover so that configuration, including the spine member, can be applied using the traditional perfect binder machine. The respective edges of the spine member are secured to the outer sheets of the end leafs by way of pressure sensitive adhesives. In one embodiment, the pressure sensitive adhesive is disposed on the edges of the spine member and covered by release sheets. After the spine structure has been secured by the hot melt adhesive, the user folds the edges of the spine structure away from the stack thereby revealing the release sheets. The release sheets are removed thereby exposing the pressure sensitive adhesive segments. The edges of the spine member are then pressed back against the stack causing the edges of the structure to be secured to the respective end leafs by the pressure sensitive adhesive. Preferably, a hardcover is secured using the end leafs and pressure sensitive adhesive.
Abstract:
Bei einem Verfahren und einer Einrichtung zum maschinellen, selbsttätigen Binden yon Buchblöcken werden in einem Arbeitsdurchlauf die Buchblöcke auf einer Fördervorrichtung stehend durch die einzelnen Bearbeitungsstationen transportiert, in einer Fächerklebebindestation (2) wird Klebstoff von unten gegen den gefächerten Buchblockrücken aufgetragen, in einer Fälzelstation (3) das Falzelmaterial direkt von einer Rolle abgezogen und maschinell auf das vorgegebene Mass selbsttätig zugeschnitten. Das Kapitalband wird ebenfalls von einer Rolle abgezogen und auf die erforderlichen Abmessungen zugeschnitten sowie mittels Schieber an den Buchblock transportiert und auf den Buchrücken aufgebügelt. Anschliessend wird das Vorsatzblatt des mit Kapitalband versehenen Buchblockes zum Aufbringen der Buchdecke am Buchblock geöffnet, vom Buchblock durch Saugwirkung abgezogen und in einer unteren Stationspresse festgeklemmt. Die Buchdecke wird dann bei geöffnetem Vorsatzpapier in einer Deckenstation (5) aufgebracht und der Buchblock mit der Buchdecke fixiert. In einer Rundungsstation (7) wird das Buch durch beidseitige Band-Klemmvorrichtungen erfasst, der Buchblock durch eine zwischen den beiden Klemmvorrichtungen angeordnete Schlaufe gehalten und durch ein seitlich zugestelltes Formteil gerundet, und das mit Decke versehene, im Rücken gerundete Buch in einer Banderolierstation (8) banderoliert und die dem Buch erteilte Rundung dauerhaft fixiert.
Abstract:
A central strip (16) of the inside surface of the cover of a book, ledger or the like is left exposed from laminating material applied elsewhere to the surface so as to bond better to the stack of pages or to a glue strip binding the left-hand edges of the pages of the book. In a preferred embodiment a central strip is cut from a sheet of laminating material as it is drawn from a roll (10) by a pair of cutters (13, 14) the spacing apart of which is adjustable to be not less than the height of the stack or glue strip.
Abstract:
The present invention regards a machine for the application of the hard cover onto a book block, commonly known as "casing-in machine", of the type which comprises a loading zone (100) where the book block (BL) is positioned, a work zone, (200) where the cover (C) is applied onto the book block (BL) and which contains the glue coating device (201), the hard cover adduction and folding device (202) and the pressing device (203), as well as a hardback book (LC) unloading zone (300). Such a machine is characterised in that, in the loading phase, the centrally opened book block (BL), is positioned onto a saddle (1), inside which a blade (2) is positioned, which blade (2), after the resting of the book block (BL) onto the saddle (1), moves therefore gradually projecting from the saddle (1), driving with itself the book block (BL) which, as a result, separates from the above-mentioned saddle (1).

Abstract:
A guide apparatus for applying a cover to a bound stack of sheets, including a base unit which defines a book receiving surface and a first alignment member having a lower cover stop disposed along a reference line, and a first upper cover stop also disposed along the first reference line. A first book stop is included defining a stack engaging surface which is positioned intermediate the cover engaging surfaces of the first upper and lower cover stops and with said stack engaging surface extending a distance past said first reference line towards the book receiving surface. The first upper and lower cover stops are positioned to engage top and bottom cover sections of the cover, with the stack engaging surface being positioned to contact the edge of the stack so as to precisely align the stack with respect to the top and bottom cover sections in one direction. A second alignment member includes elements similar to that of the first alignment member so as to precisely the align the stack with respect to the top and bottom cover sections long a second reference line normal to the first reference line.
Abstract:
Techniques for creasing a cover of a case are described herein. In an example, a creasing tool includes a first plate portion and a second plate portion substantially parallel to the first plate portion such that the first plate portion and the second plate portion define a slot between the first plate portion and the second plate portion for creasing a cover of a case.
