  • Patent number: 4361260
    Abstract: A register control (21) is provided for a web handling apparatus (22) having a drive motor (29) operatively moving a web (23) containing repetitive indicia (34) through a sequencially operating function apparatus (27) performing repetitive operations on the web. A control (41) responds to the speed of the drive motor (29) and the position of the function apparatus (27) and the position of the indicia (34) to provide a speed command signal (V.sub.c) to a full wave regenerative thyristor control circuit (38) to operatively control the operating speed of a pair of nip rolls (25, 26) through the controlled energization of a corrective motor (35) to maintain registration between the function apparatus (27) and the indicia (34). The control (41) provides a timed modification to a sensed speed signal V.sub.s for providing a modified speed command signal (V.sub.c) when the system is out of registration.
