ABSTRACT:
A log debarker of the hollow-head type having a rotor journaled in a stator for rotation about a longitudinal axis of the rotor. A plurality of debarking tools are attached to the rotor for debarking a log being moved axially through the rotating rotor. Three independently and hydraulically-powered infeed spiked rollers are positioned on the infeed end of the stator for feeding logs into the rotor and three independently and hydraulically-powered outfeed spiked rollers are positioned on the outfeed end. The rollers are powered at differing rotational speeds to accommodate logs of uneven surfaces. An air-operated tensioning system including a quick release valve adjusts the position of the infeed and the outfeed rollers urging them towards the longitudinal axis and automatically jogs the rollers open when they are unable to mount a log. A lubricating system having lubricant filtering and flow control capabilities lubricate and flushes the bearings for the rotating rotor.
