Abstract: In a device for cutting to length and feeding spine strips (3) for a case maker (1), a center strip conveying device (30) is provided that advances the spine strip material (5, 6) by the spine width (BS) transverse to the board feed direction (23) in a cyclic fashion. The spine width (BS) can be changed from work cycle to work cycle without accumulating additional waste. This can be realized because the previously required width sizing on the material web is eliminated.

Abstract: The invention pertains to a method and apparatus for producing cases with rounded corners. According to this method, the corner edge (10) that protrudes in the region of a rounded corner (9) is initially uprighted and turned over and subsequently pressed on the cover boards (7a, b, c) together with the turning-over and pressing-on of the lateral edge (11a) of an adjacent lateral border, in the same station (1). The apparatus comprises at least one rounded corner tool (3) that is arranged in the same station (1) in the which the lateral edges (11a, b) of opposed lateral borders that lie parallel to one another are uprighted, turned over, and pressed on the cover. The rounded corner tool (3) can be moved (b) toward the center of the case and out of the effective range of the lateral turn-in device (24) immediately before the turning-over and pressing-on movement (c, d) of the lateral turn-in device (24).

Abstract: An apparatus for manufacturing book covers having a board feed for supplying cover boards and a spine insert having a covering material feed for supplying covering material, having a covering material cylinder, by means of which the supplied covering material is taken over, conveyed past a glue spreading roller and assembled with the supplied cover boards and having a folding and pressing apparatus as well as having a delivery apparatus and having a drive apparatus for the covering material feed, the board feed the covering material cylinder and the folding and pressing apparatus it is provided that at least the covering material feed the board feed and the folding and pressing apparatus are drivable in each case independently of one another. The covering material cylinder is preferably also provided with an independent drive.

Abstract: An apparatus for feeding spine inserts for a machine for manufacturing book covers having a take-off roller system for withdrawing in clocked synchronism a material web cut to width by further means from a screening roll, having a cutting device for cutting off a portion of the material web as a flexible spine insert, having means of introducing the flexible spine insert into a board feed plane and having a board feed, which pushes the spine insert and further cover boards, for synchronous feeding of the boards onto a covering material, which has been coated with glue at a glue spreading roller and fed by means of a covering material cylinder a take-off roller system is provided, which inserts the material web counter to the board feed direction into the board feed plane and with which are associated guides for guiding the advanced spine insert and means of further guiding the cut-to-length spine insert as far as into the board feed plane.

Abstract: A device for storing and unrolling materials in web form in bookbinding machines having a roll-changing device for connecting a material which is to be unwound from a roll to the end of a material of the same kind unwound from another roll. The two rolls of material are placed, resting on their superficies, in an almost perpendicular shaft and are supported and guided on side walls of the shaft via their end faces. The roll of material to be stored rests on a stationary, almost horizontal floor. The unwinding roll of material rests on movable supporting elements which are set in motion, during the unrolling of the roll of material, when the latter is supported against supporting rollers forming one end face of the shaft.

Abstract: A device for continuous separation of blanks for book cover material, envelopes for brochures or similar bendable sheets of a stack of sheets from a magazine with a conveyor belt with a non-skid surface and openings acted upon by air suction, bearing the stack of sheets, feeding the lowest sheet in each case in timed fashion from the magazine, which has a suction element grasping the lowest sheet and removing it from the stack of sheets, with an air blower for creating an air cushion between the raised sheet and the following sheet and with a removal conveyor system receiving and further transporting the sheet fed with respect to a functionally reliable separation of large-format flexible sheets is characterized by supports (17, 18) on both sides of an open space supporting a stack of sheets (1) in the edge area and by a suction element (14) capable of being driven under the stack of sheets (1), grasping a sheet (1a) in the open space in the edge area, and pulling down from the stack of sheets (1) in order to

Abstract: A sheet feeder for use in a book assembling machine comprises a magazine having a movable base which defines a support plane for a stack of folded sheets. The feeder also includes a pneumatic separator, which creates a gap between a corner of the lowermost sheet of a stack in the magazine and the next adjacent sheet, and a device for injecting air into the thus formed gap to produce an air cushion. The movable magazine base functions as a conveyor to move, with the assistance of the air cushion, the leading edge of the lowermost sheet in the stack in a planar manner to a withdrawal conveying system where the sheet is engaged and subsequently pulled from the magazine. The withdrawn sheet moves, under the influence of a transfer mechanism in one embodiment, into registration with an assembly conveyor.

Abstract: A transfer device for books, inner books, newspapers, stacks or papers or similar products that are fed to a distribution point in a product stream on a high speed conveyor which includes a rotationally driven accelerator/decelerator. The speed of the accelerator/decelerator is controlled in such a manner that the product to be distributed is first accelerated to separate it from the next succeeding product in the product stream and the product is then controllably slowed so that it may be stopped at the distribution point without damage.
