Abstract:
A Rosserhead debarker having a cutter head with an improved cutter teeth mounting system. The cutter head drum defines a plurality of cutter tooth slots, each having a recess at its base. The cutter teeth are fitted into the slots with the base of each tooth closely received in the corresponding recess. A portion of each tooth protrudes from the slot to receive a blade. Each cutter tooth may be secured to the drum by a fastener extending in a generally radial direction. Each cutter tooth may include a removal stud that can be used to assist in removing the tooth from the drum. The cutter head may be mounted for axial deflection and may include a pivot yoke lock for selectively locking the cutter head against axial deflection. The pivot yoke lock facilitates certain operations where axial deflection may not be desired, including those in which only one end of the cutter head is riding on the log, such as during butt reducing. The cutter head may include a manually adjustable shoe disposed on the trailing side of the cutter head. The manually adjustable shoe may be used to limit the cutting depth of the cutter head even when only the trailing end of the cutter head is riding on the log.
