Abstract
A polymer cutter with a rotary cutting head in which the cutting edges are on the circumferential periphery of the head, and in which the cutting edges shear rather than slice the polymer is described. The knife blades on the rotary head have a cutting edge angle of greater than 70.degree.. The apparatus is especially useful for cutting thermoplastics and may be used for preparing polymer granules or pellets.
