Abstract: A moving web is divisible into a leader having a first set of registration marks and a trailer having a second set of registration marks. At a transition between the first and second sets of registration marks, a target is applied adjacent the initial mark of the second set. The target is sensed and tracked electronically to a shear. During an order change or a roll-to-roll change within an order, the web is automatically severed transversely by the shear two or more times to chop out a portion of the leader and trailer including the transition between the sets of marks. The leading edge of the trailer is tracked to a station intermediate the shear and the cut-off machine. The cut-off machine knives "crop" cut the trailer at the first registration mark following the leading edge of the trailer and thereafter cut the trailer automatically into blanks in synchronization with the second set of marks.

The target is sensed and tracked electronically to a shear station. During an order change or a roll-to-roll change within an order, the web is automatically severed transversely by the shear at the transition between the sets of marks, and the target is tracked to a station intermediate the shear and the cut-off machine. The cut-off machine knives "crop" cut the web at the target and thereafter cut the web automatically in synchronization with the second set of marks. Operation of the cut-off machine knives in the cut-to-mark mode is maintained without loss of synchronization across the transition in the web. Operator intervention is eliminated, and scrap is minimized.
Abstract: Apparatus and control circuitry used in a copy machine for providing copy paper cut to length in accordance with an original sheet sensed by a single switch in the path of travel of the original. A first feed roller is rotated via a clutch upon energization of a solenoid for the clutch when the leading edge of the original is sensed by the switch to connect the solenoid to a D.C. power supply via a capacitor. When the capacitor is nearly charged, current flow to the solenoid has diminished to a level where the armature of the solenoid is returned to its unactuated position. The leading edge of the copy paper is moved from a solenoid operated cutter to a second feed roller by the rotation provided by the first feed roll in response to the energization of the solenoid for the clutch.
