ABSTRACT:
Log debarking apparatus comprising a rotatable drum and a downwardly sloping feed chute for feeding logs into the inlet end of the drum. The drum is provided with anvil means located to prevent logs from being carried circumferentially around the drum by its rotation and carries debarking tools adapted to apply hammer-like impact blows to logs in the drum, the anvil means controlling the velocity circumferentially of the drum at which logs are supplied to such debarking tools. Adjacent to its inlet end, the drum carries a plurality of arcuately spaced apart vanes, each extending for only a minor portion of the length of the drum, which serve to control the velocity of logs supplied into the drum and cooperate with the anvil means to provide proper orientation of such supplied logs.
