Abstract: A waste stripping machine for automatically removing waste from previously die-cut blanks is disclosed. The machine incorporates a feed conveyor to deliver the blanks individually to a stripping section in planar alignment. The stripping section includes a pair of transversely spaced waste strippers which are spaced apart an adjustable distance that is equal to the width of the blank. A rack and pinion traversing mechanism is included to easily move one waste stripper relative to the other for blank size adjustment purposes. Each waste stripper is fabricated with a driving belt and two driven belts whereby one driven belt defines a planar waste engaging area with the driving belt and the other driven belt defines a circular waste engaging area with the driving belt. The machine is powered by a single motor which functions the feed conveyor and the waste strippers in synchronism to deliver the stripped blank to discharge rollers, which rollers are also rotated in synchronism.

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.
