Abstract
A machine is capable of cutting into small pieces the thin wall material of a plurality of disposable containers such as plastic bottles or metal cans fed in a first direction one at a time to a cutting section. The cutting section includes a pair of parallel shafts mounted for rotation in opposite directions about the center axes thereof. Each of the shafts rigidly supports a plurality of overlapping cutting wheels for rotation therewith. Each cutting wheel has a plurality of identical cutting teeth thereon having an apex at the maximum diameter and a root at a root diameter of the cutting wheel. Each cutting tooth has a leading surface and a trailing surface which meet at the apex to form a straight edge at the maximum diameter which is parallel with the center axis of the shaft. The leading surface and the trailing surface respectively lie in planes which are parallel with the center axis of the shaft and extend toward the same side thereof to cause the straight edge of the apex to circumferentially lead a remainder of the leading surface during rotation of the cutting wheel.
