ABSTRACT:
A corrugated thin metal strip is advanced through a cut-off mechanism having a movable upper blade and a lower stationary blade. A curtain of air is directed downwardly against the tip of the corrugated strip to momentarily arrest its movement with a return bend between a pair of adjacent convolutions of the strip centered over the stationary blade. The upper blade descends and shears the strip transversely along a return bend.
