Abstract

A sheet delivery has an endless conveyor for conveying printed sheets and a secondary gripper with a gripper bar for holding printed sheets received at their trailing edges from the endless conveyor, to be deposited on a delivery stack. A transmission generates an annular circulatory movement of the gripper bar. A first balance weight and a second balance weight are provided for compensating for interference torques and are braced for rotation in relation to one another by a spring.
