Abstract
The present invention relates to a phase shifting debarker comprising crank arm mechanisms. The shifting debarker comprises a phase shifting mechanism powered by a main motor and connected to an operative assembly by the mean of timing belts. The main motor is configured to control, by means of a belt, the movement of the phase shifting mechanism which is adapted to control the movement of the operative assembly by means 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. The shift phase creates pressure from the rings to a crank arm mechanism, the crank arm mechanism transmitting said pressure to a pressure control system that finally transmits it to the operative assembly arms for debarking.
