Abstract
The actual position of a leading edge of a transversely folded signature is detected. This actual position detection event is used to trigger an instantaneous measurement of the actual angular position of the gripper system used for receiving the signature. If the leading edge of the signature is predicted to arrive at the gripper system of the receiving cylinder at other than the appropriate time, the speed of the receiving cylinder is corrected.
