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).

Dependent claims

A device for feeding book blocks (2) into a book block transport system (11.1, 11.2) of a perfect-binding machine (1.1, 1.2), comprising:

a book block transport system (11.1, 11.2) including a plurality of open and closable book block clamps (12, 13) that are connected to one another in spaced relation and are movable continuously with a common drive (17) along a closed loop in a forward direction through a book block receiving location where each open clamp is closed;
a feeding device (21.1, 21.2) including a driven (28) transporter (22) with pusher bars (25) that push upright book blocks (2) forward to said receiving location, a spine support (26) for the pushed book blocks (2), and lateral guides (27);
wherein the transporter drive (28) is controlled by a control device (20) in dependence on a position of each book block clamp (12, 13) such that each pusher bar (25) moves to a defined position relative to the corresponding book block clamp (12, 13) in association with the closing of this book block clamp (12, 13) at said receiving location.
