Abstract
An improved machine for cutting into small pieces the thin wall material of disposable containers includes parallel, rotating cutting shafts having a plurality of cutting wheels thereon. The cutting wheels are separated by annular spacers which provide a rotating comber surface. There is a spacer comber partially encircling each of the annular spacers which has a lower section having a rounded surface. A cutting wheel comber partially encircles each of the cutting wheels and has a lower end with a rounded portion. The spacer combers having the rounded surface and the cutting wheel combers having the rounded portion prevent the collection of the small pieces within the improved machine.
