摘要： A system for incremently and continuously feeding tubes between dies during a prescribed angle of rotation of a crank assembly in a cold pilger mill. As a main motor drives the crank assembly, a servo-motor, receiving a signal from a digital control unit, which receives a signal from a pulsating encoder associated with the main drive, operates to incremently advance a carriage and shell a controlled predetermined distance between the dies. A reversal of the servo-motor returns the carriage to the initial position in preparation to advance another shell.
