ABSTRACT:
A blade assembly has a support shaft extending along an axis and having an end member and a polygonal-section portion extending axially from the end member. A plurality of like metallic support disks are supported on this shaft and have central holes traversed by and complementary to the polygonal-section portion and outer peripheries. Respective metallic blades lie flatly axially on the support disks and each have a radially outwardly projecting cutting portion extending radially outwardly past the outer periphery of the respective support disk. The blades with the respective support disks are axially spaced along the polygonal-section portion. Respective fasteners engaged axially through the support disks and the respective blades secure each blade to the respective support disk for joint rotation therewith. A plurality of spacer rings of a polyoxymethylene each engage axially in one direction on one respective blade and the respective support disk and axially in the opposite direction on the adjacent blade and the respective support disk. Another end member screwed onto the support shaft presses the support disks, blades, and spacer rings axially together against the other end member.
