Abstract

Sheet material handling apparatus comprising a transfer vehicle movable along a guide track between a stack pickup position and a stack discharge position. The transfer vehicle has a clamping mechanism for clamping a stack of signatures at the stack pickup position and for removing the stack of signatures from the stack pickup position. The clamping mechanism is adapted to maintain clamping engagement with the stack of signatures as the transfer vehicle is moved along the guide track away from the stack pickup position and to the stack delivery position, and the clamping mechanism is releasable from the stack of signatures at the stack delivery position.
