Abstract

A chain conveyor for transporting sheets in a printing press. The chain conveyor includes two conveyor chains disposed opposite one another and revolving together during operation, and at least one gripper bar extending in a direction transverse to and between the two conveyor chains. An expansion joint is provided to connect one end of the gripper bar to one of the conveyor chains and to allow movement of the gripper bar in the direction transverse to the two conveyor chains. The expansion joint may also allow rotational movement of the gripper bar. The expansion joint reduces wear of the conveyor chains by allowing the gripper bar to move.
