Abstract: In a machine (1) for manufacturing perfect-bound brochures (2) that includes a book block conveying device (10) with an endless conveying means (11), a plurality of clamps (14) that are arranged on the conveying means at a fixed pitch spacing (T) and serve for clamping book blocks (3, 3.1 . . . 3.8), and of at least one processing station (25, 18, 19, 20, 21, 22, 30) that can be adjusted in a motor-driven fashion, the cycle time (t0) referred to the conveyance of the clamps (14) by the pitch spacing (T) defined in the at least one processing station is divided into an adjusting segment (tV1, tV2) for resetting and/or adjusting the at least one processing station (25, 18, 19, 20, 21, 22, 30) in accordance with changing printed product characteristics and a processing segment (tB1, tB2) for processing the book blocks (3, 3.1 . . . 3.8) and/or covers (4, 4.1 . . . 4.4).

Abstract: In a cover feeding device (1) for feeding covers (13, 13.1, 13.2, 13.3) separated from a magazine (3, 3?) to book blocks (14.1, 14.2, 14.3) that are transported while being clamped in book block grippers (2), it is proposed that the magazine (3, 3?) features at least a first lateral stop (6.1) that is arranged such that it can be fixed transverse to the withdrawal direction (12) and against which different covers (13, 13.1, 13.2, 13.3) intended, in particular, for book blocks (14.1, 14.2, 14.3) of different thickness can be jointly placed, and that at least the magazine (3, 3?) can be adjusted transverse to the withdrawal direction (12) such that an edge (17) of the spine region of the respective cover to be separated is withdrawn essentially in alignment with the rigid gripping jaw (2 a).

Abstract: A book binding machine for processing book blocks (3) features a transport system (2) with a plurality of book block clamps (40) for receiving the book blocks (3) that can be continuously moved along a closed circulation path and are coupled to a traction mechanism (63), wherein the traction mechanism (63) revolves around a driving wheel (55) and a deflection wheel and is tensioned by means of a tensioning device. Processing stations (70, 80) are arranged in the region of straight sections of the circulation path. The driving wheel (55) is driven by a gearless, rotative electric direct drive (50), wherein a first rotating component (53) of the rotative direct drive (50) is mounted or realized directly on the driving wheel (55).

Abstract: A bookbinding machine for processing inner books includes a transport system with a multiplicity of inner-book clamps continually movable in a closed continuous track. Each of the inner book clamps is articulated to a circulating roller chain and has a rear-edge stop for aligning the inner books. The bookbinding machine includes workstations that perform positionally accurate operations on the inner books including the application of glue, the application of reinforcement or gauze sections, the application of jackets, binding with wire stitches, the introduction of utilisation features (e.g. punched holes, tear-off perforations, etc.) and the like. The transport system of the inner-book clamps and at least one workstation are driven independently of one another. A measuring system for positional detection of the inner-book clamps or of the inner books is provided in proximity to the independently driven workstation.
