ABSTRACT:
A transfer vehicle with a special clamping mechanism for clamping a stack of signatures supported on a stacker, and for maintaining clamping engagement with the stack as the transfer vehicle moves the stack to a delivery position. The clamping mechanism can bring an end board over to the stacker, and deposits the end board on the stacker as the clamping mechanism engages a stack. The clamping mechanism also has independently movable clamp members that can move to different coextents in applying pressures to different portions of a stack of signatures during the clamping process. Still further, the clamping mechanism is designed to positively contain a signature stack that is removed from a stacker.
