Abstract
Abstract A print to cut register system for establishing and maintaining registration between a pattern on a moving web and a cutting die by controlling the operative condition of a pair of web feed rolls. The print to cut register system incorporates an electric signal means responsive to the output of a registration error detector. The electric signal means, which may include a computing resolver, provides an output signal proportional to the alteration in the web feed rolls necessary to correct the detected registration error. The electric signal means is connected to electromechanical means having a servomotor for converting the output signal of the electric signal means into a corresponding shaft speed and rotary direction signal. The servomotor shaft speed and rotary direction signal is amplified by the torque amplifier and provided through a differential drive means to the feed rolls to correct the registration error.
