Abstract: A gatherer stitcher for collating signatures made of paper, paperboard and the like, for stitching the collated signatures and for delivering the stitched signatures, includes a gathering section, a stitching station and a delivery station. The stitching station has a stitching carriage with at least one stitching head and, during a stitching operation, the stitching carriage is moved by a stitching carriage drive at a speed of the collated signatures. A switching unit is disposed between the stitching carriage drive and the stitching carriage for adapting a stitching carriage movement to a gatherer chain pitch, that is to say for adapting a horizontal reciprocating movement of the stitching carriage, and for adapting a horizontal distance between the stitching carriage and the delivery station.

Abstract: An automated multiple point fastener driving system is disclosed for driving fasteners into a plurality of structural elements for connecting the elements together while the elements are substantially continuously moving along a path The automated multiple point fastener driving system includes a frame with the path extending through the frame for movement of structural elements, a moving assembly for moving a plurality of structural elements along the path in a substantially continuous manner, an entry clamping assembly for clamping together the structural elements as the elements move substantially continuously along the path, an alignment assembly for aligning at least one edge of the plurality of structural elements as the elements move substantially continuously along the path, and fastener driving assembly for driving fasteners into the plurality of structural elements as the elements move substantially continuously along the path.

Abstract: A transport table reciprocates between a collator, at which it receives a stack of loose sheets, and a stapling head for stapling the sheets together. Cam followers on the table engage cam surfaces during the reciprocating table movement to cause jogging movements of end and side retaining means to jog the loose sheets into a neat stack. The stack is delivered into a gap between the stapling head and an anvil, and the stapling head moves through a first half cycle, forming a staple and clamping the stack. A gate on the transport table lifts to free the stack while the table retracts, and then the stapling head drives the staple through the stack. The gate lowers when the transport table returns to its original position.
