CUTTING KNIFE ARRANGEMENT FOR USE WITH SOFT MATERIALS

摘要

A cutting knife arrangement employs a plurality of cutting knife inserts mounted on a common circular cylinder. Cutting knife inserts are mounted on a holder device secured to the outer periphery of the cylinder. The cutting knife inserts have a rectangular cross- section with each corner edge comprising a cutting edge. By indexing the cutting knife insert, different cutting edges of the same insert can be presented for use in a cutting operation.
