ABSTRACT:
A continuous metal strip is fed lengthwise along a line of dies intermittently from one end of the line to the other beneath a vertically reciprocating ram carrying a plurality of punches that are slidable vertically in the ram from a projecting operating position to a retracted inoperative position. Each punch is selectively movable automatically from either of those positions to the other independently of the rest of the punches so that different punches can punch a strip at different times while the strip is passing through the press.
