NHL-SH-01 Canada METHOD AND APPARATUS FOR CUTTING DISPOSABLE CONTAINERS ABSTRACT OF THE DISCLOSURE A machine is capable of cutting into pieces disposable contain- ers 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. The cut- ting wheels include a plurality of cutting teeth and cutting wheel spacers maintain the cutting wheels in a spaced relationship on the shafts to prevent damaging contact between the teeth. A comber is aligned with each cutting wheel to provide a gap between the cutting teeth and the end of the comber and is maintained in alignment to prevent damaging contact with the teeth of adjacent cutting wheels. 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. The invention also includes the method of cutting the disposable con- tainers in pieces.
