Abstract
Printed products arriving in an imbricated product formation are fed to spaced gripper units of a transport device by a belt conveyor. The conveying direction of the belt conveyor forms an acute angle with the transport direction of the transport device. The transporting rate or velocity of the belt conveyor is greater than the transporting rate or velocity by the transport device. Each gripper unit comprises a stationary clamping jaw, a pivotable clamping jaw, and a plate-shaped stop. The pivotable clamping jaw is pivoted against the action of a closing spring by a cam structure or the like. The printed products are first accelerated and then pushed into the open gripper mouth until abutting the stop in order to thereby align the printed products at the region of their leading edges. At the region of their trailing edges, the printed products remain under the conveying action of the belt conveyor at least until the gripper units are closed.
