Abstract: The specification discloses a method for constructing an improved cutter cone (12) for a food processing machine (10). A plurality of elongated slits (32) are cut axially along the surface of the frustroconical surface (40). A selected edge of each of the slits (32) is bent internally of the conical surface (40) at a predetermined angle to the cone to form a louvered surface (42). The inside of each louvered surface (42) is ground by means of an emery wheel to form a cutting edge (36). Each louvered surfaces (42) is then bent outwardly of the conical surface (40) at a predetermined angle to form a series of working surfaces each having an interiorly beveled cutting edge (36). The exterior of the working surfaces (34) is then polished by means of a buffing wheel to eliminate burrs.

Abstract: A saw blade construction and method of forming such blade whereby the ends of a saw blade are abutted into end to end relationship to define an endless saw blade having a series of teeth formed along one edge to define a cutting edge, and having a back edge which is progressively sloped or tapered in opposite directions from an intermediate point on the back edge so that in a cutting operation the saw blade effects a cut along an edge portion of a workpiece on the down feed stroke of the blade and a progressive cut on the opposite edge of the workpiece whereby the teeth are rendered self-feeding on the progressive cut of the workpiece. In a modified embodiment the saw blade is formed with a plurality of alternate disposed down feed and progressive cutting edges.
