Abstract: An electric motor driven roll feed system for intermittently advancing stock into the work station of a punch press. The roll feed system is designed so that its main rotating elements have greatly reduced rotational inertia. A low inertia overall roll arrangement is characterized by two relatively small diameter cooperating feed rolls that are respectively radially supported by a plurality of light back up rollers that peripherally engage these small feed rolls at locations spaced along the operative lengths of such feed rolls. The spaced rollers thus allow the applied operational stock gripping, feeding and braking forces to be distributed over several support locations along the operative axial length of each feed roll.
