Abstract: The invention claimed is directed to a signature collating system comprising stations (2) which are adapted to deliver signatures (3), as well as a transport (4) adapted to pick up the signatures (3) to form stacks (5), a diverting device (7) located downstream from the stations (2) and adapted to controllably convey the stacks (5) out of the transport (4), a reclaim belt (9a) extending from the diverting device (7), to a position of the transport (4) upstream of the stations (2), a signature (3) withdrawal station (9b) located on the reclaim belt (9a) and comprising a pull-out means (12) adapted to remove signatures (3) from the stacks (5), and a monitoring means (6) adapted to detect anomalies in the delivery of the signatures (3) and the positions of the stacks (5), and adapted to control the activation and deactivation of the stations (2), diverting device (7), and withdrawal station (9b).

Abstract: The invention is concerned with the field of devices for spread-applying liquids, and in particular, with a device and method for spread-applying glue on the spine region of a book.The technical problem to be solved was that of providing bookbinding machines which could spread glue controllably and evenly, and apply said glue on all the suitable locations for glueing and only there.The problem is solved by providing a device which has a pair of containment lateral sides arranged at extrusion nozzles and alongside the path followed by said book spines, said lateral sides being movable to and away from each other and defining an extrusion chamber which envelopes both said spine and book edges adjacent it, and has a working chamber operative to supply said nozzles with glue and being confined between two juxtaposed pressure elements which are movable together with said containment lateral sides.
