Abstract
A roll type stock feed apparatus for a power press. The stock feed apparatus has a pneumatic system for actuating the feed rolls between stock feed and stock release positions. Pressurized air in a substantially constant pressure is applied to one side of a pneumatic actuator to press the feed rolls into feeding engagement with strip stock between the rolls, and pressurized air is selectively applied and exhausted from the other side of the actuator piston to respectively release and apply feeding pressure to the stock feed rolls. An adjustable stop is provided to limit movement of the actuator pistons in a stock release direction.
