Abstract

A sheet delivery has an endless conveyor for conveying printed sheets, and a secondary gripper with a gripper bar that receives the printed sheets from the conveyor at their trailing edges and deposits them on a delivery stack. A transmission generates an annular circulatory movement of the gripper bar. The endless conveyor has lower forward strands, running toward the delivery stack, and upper return strands, running away from the delivery stack. The transmission has a first control-cam pair on one side of the endless conveyor and a second control-cam pair on the other side of the endless conveyor and the two control-cam pairs are connected to one another via a common shaft. The shaft is disposed above the return strands.
