Abstract

In a device for the transport of sheets in a sheet-processing machine, preferably a printing press, provision is made to transport the sheets on chain-guided gripper bars. The gripper bars are fixed respectively to two chain links arranged indirectly beside each other. The forces acting on the gripper bars are more evenly distributed.
