Abstract
A method and apparatus achieve the intermittent feeding of raw material into a shearing station by exerting a drive torque on draw-in rollers in order to effect their rotation in one arcuate direction and hence the movement of the raw material toward the shearing station. A counteracting torque, which is less than the drive torque, is continuously exerted on the draw-in rollers. Thus, during intervals following a shearing operation when the drive torque is terminated, the counteracting torque functions to reverse the rotation of the draw-in rollers and hence retract the sheared end of the raw material away from the shearing station.
