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).
