摘要：A gripper drum for gripping printed products includes a drum shaft; at least one gripper disk coupled to the drum shaft; a gripper shaft disposed on the at least one gripper disk and having a shaft body rotatable about its longitudinal axis; an apparatus for controlling the gripper shaft; and a plurality of grippers disposed on the shaft body. The grippers are adaptable to be rotated about the longitudinal axis of the gripper shaft for gripping the printed products. The gripper drum further includes a tensing apparatus coupled to the gripper shaft for compensating any play between the controlling apparatus and the plurality of grippers. The gripper drum operates to define an opening movement and closing movement of the grippers.
