Abstract: In a feed device (1) for a perfect binder, it is proposed that a vibrator device (5) features at least one first vibrating plate (6.1) that is inclined relative to the horizontal line and on which the sheet stacks (2) are aligned while they stand on first sheet edges (2 a) and second sheet edges (2 b) contact an aligning element (6.2) that is stationarily arranged in a plane lying perpendicular to the first vibrating plate (6.1), and that a conveying device (30) is realized in the form of a clamping conveyor (30, 31.1 . . . 4) for receiving aligned sheet stacks (2) from an inclined, stationary position (21) in the vibrator device (5) and for synchronously, positively transferring (22) said sheet stacks to the continuously driven book block conveying device with the block spine (2 a) positioned horizontally.

Abstract: In a feed device (1) for a perfect binder, it is proposed that the conveying device (30) features at least one clamping carriage (31.1 . . . 4) that takes hold of sheet stacks (2) that were aligned in the vibrator device (5) and stand on the block spine (2 a) laterally on the block spine (2 a) by means of clamping strips (33.1, 33.2) and supports the block spine (2 a) on supporting plates (32), wherein this clamping carriage receives the sheet stacks from an inclined designated position (21) and horizontally transfers said sheet stacks to the book block conveying device. The sheet stacks (2) are no longer pushed into the perfect binder through a channel, but rather transported by the clamping carriage (31.1 . . . 4) in a laterally clamped fashion.

Abstract: A cover feeding device for a book binding machine features a transport device for feeding covers (1) decollated from a magazine (11), a conveyor (12) that is arranged underneath the plane of motion of the book blocks (7) a pressing device (14) that presses the covers against the spine and a printing unit (17) that prints content (8) onto the cover (1). The transport device comprises a turning device (21, 31a, b, 41) for transporting the covers (1) such that the outside (3) is at least partially directed upward during their infeed, and the printing unit (17) is arranged above the cover transport.

Abstract: A perfect-binding machine (1.1, 1.2), has a main transport system (11.1, 11.2) with revolving clamps (12, 13) and a feeder (21.1, 21.2) including a transporter (22) with pushers (25), a support (26) for the upright book blocks (2) in the spine region, and lateral guides (27). The drive (28) for the transporter is controlled in accordance with the position of the clamps such that an assigned pusher (25) moves aligned in a defined position relative to the corresponding clamp immediately before and/or during the closing of this clamp (12, 13). The book blocks (2) are fed to the respective clamps in an aligned fashion such that the transfer and the alignment of the book blocks on book stop catches on the clamps can be eliminated. Book blocks (2) can be fed to the book block clamps (12, 13) in such a way that they are clamped centrally (M).

Abstract: A book block transport system with a plurality of book block clamps (1) each having a supporting frame (2) that is supported in guides and carries an inner clamping jaw (3) and a pivot frame (4) that is suspended on a shaft (6) of the supporting frame (2) extending parallel thereto for accommodating an outer clamping jaw (5). The pivoting movement for opening and closing the outer clamping jaw (5) is controlled by a cam track, with a spring element (13) that generates the clamping force between the inner and outer clamping jaws (3 and 5). A book stop catch (30, 40) is carried on the book block clamp (1) for aligning the book block supplied by an infeed device. In order to reliably and flawlessly transfer and align the book blocks supplied by an infeed device, the book stop catch (30, 40) is arranged on the book block clamp (1) such that it can be moved relative to the inner clamping jaw (3).

Abstract: The invention relates to a book block clamp (1) for clamping and transporting book blocks (2) in book block processing machines, comprising an inner clamping jaw (5) and comprising an outer clamping jaw (6) which is arranged parallel to, and movable in relation to, said inner clamping jaw (5). A support element (20) is associated with the outer clamping jaw (6), which support element (20) can be moved into a position that is spaced apart in parallel in relation to the outer clamping jaw (6), as a result of which the opening width of the book block clamp (1) is reduced, while the distance between the inner and the outer clamping jaw (5, 6) remains unchanged.

Abstract: A method and apparatus for feeding a cover (10, 11, 12, 13) in the production of perfect-bound or saddle-stitched books, brochures, magazines or similar printed products (14, 15) featuring an inner part (2) that consists of a collection of folded sections, layers and/or individual sheets and a cover (10, 11, 12, 13) that is placed around the inner part (2) and connected thereto. A roll (3) comprising a wound-up cover web (4) is supplied, the cover web (4) is unwound and a cover sheet (10, 11, 12, 13) with the desired format height is separated from the cover web (4, 8) and fed to the inner part (2) in order to be placed around the inner part and connected thereto. This allows a reliable and flawless feed of the covers to the inner parts, and the operating effort for the cover feed is reduced.
