Abstract
A log delimbing processor includes two pairs of grapples for holding workpieces for translation along their length so as to engage delimbing knives. The workpieces are urged by a pair of driven wheels on opposite sides of the workpieces, by a driven upper roller mounted to a backbone of the processor, and by a driven lower roller mounted on the end of an articulated arm which is actuated to tuck up under the workpieces held in the grapples so that the workpieces are engaged and driven from all sides. A swing out saw on one end of the processor provides for delimbing large forked branches.
