Device for feeding book blocks into the infeed channel of a subsequent processing arrangement

A device for feeding book blocks (2) standing in an upright orientation on a spine or fore edge cut, to subsequent processing equipment, comprising:

• an infeed channel (11) for the subsequent equipment, having a channel bottom (12), lateral channel guides (13) and at least one pusher (14) with an operatively associated first drive that pushes the book blocks (2) standing on their spine (2 a) or fore edge cut forward into the equipment along a conveying direction;
• a book block feeder (30) that feeds the book blocks (2) into the infeed channel (11) vertically from above, transverse to the conveying direction of the infeed channel (11);
• and
• at least one push-out unit (51) with an operatively associated second drive separate from the first drive, which pushes vertical book blocks from the book block feeder (30) into the infeed channel (11) along said conveying direction.
