ABSTRACT:
A rotor assembly for a shavings making machine having a plurality of knife and wedge assemblies is disclosed. The knife and wedge assemblies are removably mounted in channels or pockets extending parallel to the rotor axis along the length of the circumference of the rotor. In mounting each knife and wedge assembly to the rotor, the knife insert is first mounted on the respective wedge insert and the wedge insert is then mounted on the rotor. The bolts or other means for mounting each knife insert on the wedge insert are located below the periphery of the rotor and adjacent one side wall of the respective channel such that the bolts cannot back out or become loosened due to vibrational forces. Each knife insert has two reversible blades which are symmetrical. A flattened surface on the rotor adjacent each knife insert assists in providing an effective cutting operation. The metallurgical composition of the knife inserts can be varied to accommodate the material in a particular application.
