ABSTRACT:
A method and mechanism for slicing oversize wood chips including a housing, a cylindrical drum rotatable within the housing, an anvil rotor rotatable within the drum and having a plurality of arms with a blade mounted on each of the arms to move chips along the inner surface of the wall of the drum, said drums having slots therein with knives adjacent the slot so that chips are cut as they are moved along the wall past a slot, and the knives and blades at a relative angle to each other with either one or both of them being at an angle to the axis of the drum and rotating the drum within its housing and rotating the anvil rotor at a slower speed so that the chips are pushed against the inner wall of the drum by centrifugal force and are cut by the scissor action between the blade and knife.
