ABSTRACT:
A machine for corrugating lengths of continuous strip stock that includes first and second sets of corrugation-forming rollers for receiving strip stock from associated coil rolls and feeding corrugating stock to vertically spaced slots in a shared cutting station. Running length of each corrugated strip is measured and the cutting station is controlled so as to obtain severed stock sections of predetermined lengths, which may be variably programmed in a predetermined sequence. The cutting station includes a stationary plate having vertically spaced strip-receiving slots, and a pair of shear blades integrally formed on a shear plate selectively driven by the machine controller through a cycloidal drive mechanism.
