Abstract:
The delimber-debarker comprises a suitable frame, a cutter carriage carried in the frame and being driven by a motor through a sprocket and chain, a plurality of cutting heads mounted on journaled shafts provided with pinions operable to engage a ring gear on the carriage and to drive the cutting heads carried in each of the respective cutters, and a feed assembly carried on the frame and being operable to drive a log through the carriage and between the cutters.
Abstract:
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.
