Abstract
An improved machine for cutting material into at least narrow strips includes parallel, rotating cutting shafts having a plurality of cutting wheels thereon. The cutting wheels are separated by spacer-comber elements which provide a comber surface in alignment with a cutting wheel on the other shaft. A cutting wheel comber is mounted between adjacent spacer-comber elements and includes a concave surface to partially encircle the cutting wheel therebetween. The cutting wheel comber has a discharge end toward the discharge side of the machine with a rounded portion. The regions along the concave surface is separated by different distances from the cutting wheel to prevent the retention and collections of the narrow strips of material at the backsides of the cutting wheels.
