Wood shavings forming apparatus and cutting roll adapted for use therewith

摘要

An apparatus for forming wood shavings from wood stock includes a rotatable cutting roll for engaging and cutting wood shavings from a wood stock advanced by a feed mechanism along a predetermined path of travel to the roll. A rotatable roll of the feed mechanism has peripheral teeth that engage the wood stock and control its advancement along the path of travel. The teeth are inclined rearwardly relative to the direction of rotation of the roll so that the teeth have a negative rake angle. An anvil is positioned adjacent the end of the path of travel and closely adjacent the cutting roll for restricting advancement past the cutting roll of pieces of wood stock other than the shavings.
