End-paper gluing unit for an adhesisve-binding machine

摘要

The end papering device for an adhesive binding machine for positioning and laterally bonding end sheets to the first and last folded sheets of a book block has a transfer channel for feeding the book block to a clamping jaw conveyor of the adhesive binding machine with separate end sheet channels along the transfer channel, to which end sheet channels feeding apparatuses are assigned for separating and feeding the end sheets into the channels. The device has transport elements for advancing the book block and the end sheets together into the clamping jaw conveyor and glue application discs for gluing the end sheets to the first and last folded sheets. The end sheet channels (8; 23) make a transition from an initial position, parallel to the transfer channel (2; 18), into a continuously sloping end position. Arranged in the region of this end position are glue application discs (10; 26) which engage from below in the end sheet channels (8; 23) for applying a strip of glue to the regions of the end sheets (1a, 1b) near to the back which are deflected by the end sheet channels (8; 23), the glue application discs (10; 26) have sloping application surfaces (10a; 26a), corresponding to the end sheet channels (8; 23), which application surfaces are in effective connection with contact surfaces (8a; 23b) of the end sheet channels (8; 23). Furthermore, means (30) are provided for pressing on and, if appropriate, means (23, 25) for advancing the end sheets (1a, 1b) to the book block 1. IMAGE
