Abstract

A machine is capable of cutting into pieces disposable containers such as plastic bottles and metal cans. A first cutting section includes a pair of parallel shafts mounted for rotation in opposite directions. Each of the shafts supports a plurality of cutting wheels keyed for rotation therewith. The cutting wheels of one shaft overlap the cutting wheels on the other shaft as each cutting wheel is axially separated from axially adjacent cutting wheels thereon by one of the cutting wheels on the other shaft. A comber is aligned with each cutting wheel to provide a gap between the cutting teeth and the end of the comber. The disposable containers are cut into first pieces between the cutting wheels of one shaft and the cutting wheels of the other shaft. The first pieces from the first cutting section pass to a second cutting section to be cut into smaller, second pieces.
