A feed system for a punch press includes a first clamping and advancing mechanism for gripping feed stock and moving it toward the press, and a second clamping and advancing mechanism for gripping the stock and conveying the stock away from the press. A controller causes the first clamping and advancing mechanism to be operated until a predetermined number of punching operations have been performed upon the stock while the second clamping and advancing mechanism remains inoperative. After the predetermined number has been attained, the second clamping and advancing mechanism is activated and punch operations continue until a second predetermined count has been attained. Thereafter, the stock is conveyed away from the press. The invention permits stock to be conveyed through the press very rapidly, and it prevents damage to the press by accurately determining the position of the stock relative to the press.
A feed system for delivering individual pieces of stock to a punch press, the press having a punching station, an infeed portion upstream of the punching station, an outfeed portion downstream of the punching station, and a control mechanism to control operation of the press, the combination comprising:
