Abstract
A method and apparatus for cutting corrugated webs from a strip which is continuously formed to define undulating fins or corrugations extending transversely of the strip. The method and apparatus comprise periodically interrupting the movement of the corrugated strip, spreading a corrugation in the direction of the longitudinal axis of the strip and severing the corrugation at the spread corrugation and the apex of the corrugation. More specifically the corrugated strip is interrupted, the adjacent corrugations are moved longitudinally relative one another to locate the corrugation to be cut and a cutter is moved between the adjacent apices to cut the connecting oppositely disposed apex. In one form adjacent apices are engaged and spread apart. In another form, a finger engages a side of a corrugation to position the corrugation to be cut.
