ABSTRACT:
A stripping element includes an elongate hold-down bar that fits between adjacent incisor rings on a rotating drum wood incisor and prevents the teeth on the incisor rings from tearing chunks of wood from the piece of lumber as the teeth pull out after having made perforations. The hold-down bar has a planar lower surface which is parallel or slightly angled from the surface of the piece of lumber and is slightly separated from this surface. The apparatus includes a mounting structure that permits changing the distance between the lower surface of the hold-down bar and the surface of the piece of lumber. The stripping element also includes a cleaning pick which removes any wood chunks that become lodged between the incisor rings.
