ABSTRACT:
A gripper-accumulator and system for gripping, accumulating and transporting two or more pieces along an production line. The gripper-accumulator is particularly useful in accomplishing higher production speeds in the production of periodicals and magazines. The gripper-accumulator has two or more gripper-fingers and a fixed support extending radially out of a hub. The gripper-fingers are capable of rotating around the hub from a initially open to a eventually closed position adjacent to the fixed support. At the closed position a piece is gripped between the fixed support and the gripper-finger, or between two adjacently located gripper-fingers. Thus, a single gripper-accumulator is provided that is capable of holding several pieces thereby speeding production.
