Abstract
A lumber incisor comprising a rotatable drum. A plurality of annular incisor rings are mounted on the drum to turn with the drum. Teeth on the periphery of each incisor ring, extend outwardly from a tooth base on the periphery of the incisor rings. An annular spacer ring is positioned between each pair of neighboring incisor rings. An annular cleaning ring surrounds each spacer ring and is freely movable between the neighboring incisor rings. Each of the above annular rings has an inner radius, an outer radius and a ring width equal to the outer radius less the inner radius. The spacer rings have an outer radius less than the outer radius of the incisor rings. The outside diameter of each cleaner ring is at least equal to the incisor ring outside diameter plus a height of one tooth.
