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.
