A debarking machine is provided with a plurality of rotors disposed in parallel, and a gap between the rotors is blocked by a comb-tooth shape partition plate. The debarking machine is further provided with a log accommodating body, rotors rotatively mounted inside the log accommodating body and provided with debarking plates, a comb-tooth shape partition plate base disposed at a space between the rotors, a comb-tooth shape partition plate detachably mounted on the comb-tooth shape partition plate base, and a fixer for fastening the comb-tooth shape partition plate to the comb-tooth shape partition plate base. The comb-tooth shape partition plate is composed of partition plate elements divided along the axial directions the rotors, and each partition plate element is detachable separately. Thus the comb-tooth shape partition plates can be rebuilt and replaced easily.

The present invention relates to a phase shifting debarker. The shifting debarker generally comprises a phase shifting mechanism being powered by a main motor and being connected to an operative assembly by the mean of timing belts. The main motor is being configured to control, by the mean of a belt, the movement of the phase shifting mechanism which is being adapted to control the movement of the operative assembly by the mean of the timing belts. The operative assembly generally comprises an actuator ring and a main ring. The activation of the shifting mechanism creates a shift phase between the actuator ring and the main ring while rotating at the same speed.
