ABSTRACT:
A press feed capable of being driven in synchronization with a press. The press feed includes a sensor for sensing a selected phase of a press cycle of the press, structure for engaging stock material adapted to be fed by the press feed to the press, and an infinitely variable release device connected to the stock material engaging structure and communicating with the sensor. The infinitely variable release device operates to move the stock material engaging structure in a first direction relative to the stock material responsive to detection by the sensor at the onset of the selected press cycle phase, and to move the stock material engaging structure in a direction generally opposite the first direction responsive to detection by the sensor at the termination of the selected press cycle phase. The infinitely variable release device may be a servo controlled drive screw.
