Device For Feeding Book Blocks To A Book Binding Machine

A device for feeding book blocks (2) in the form of sheet stacks (2) to a book binding machine, comprising

• a continuously driven book block conveying device (4) with clamping elements (3) that laterally clamp the sheet stacks (2), with a stack spine edge (2a) downwardly protruding from the clamping elements (3),
• a vibrator device (5) for aligning the sheet stacks (2), and
• a transfer conveying device (30) for the synchronous transfer of the sheet stacks (2) to the book block conveying device,
• wherein the transfer conveying device (30) includes at least one clamping carriage (31.1 . . . 4) that takes hold of sheet stacks (2) that were aligned in the vibrator device (5) and that stand on the stack spine edge (2a), by laterally clamping at the stack spine with clamping strips (33.1, 33.2) and supporting the stack spine edge (2a) on supporting plates (32), and wherein said clamping carriage (31.1 . . . 4) receives the sheet stacks from an inclined designated position (21) and horizontally transfers said sheet stacks to the book block conveying device.
