ABSTRACT:
A plurality of transversely adjustable rotary stripping wheels of general disc-like configuration for use in a stripping machine for removing automatically the waste material from die cut blanks. The outer periphery of the stripping wheel is knurled to enhance frictional engagement between the wheel and the waste material during the stripping operation. A plurality of half-rounds are milled or otherwise provided in spaced locations about the periphery of the stripping wheel to provide a positive gripping action upon the leading edge of the die cut waste to urge the leading edge downwardly during the stripping operation.
