The present invention is a debarking ring apparatus to prevent operational downtime of logs debarking by having two debarking rings placed on the same vertical plan, perpendicular to the flow of incoming and outgoing logs, and parallel to each other. Only one ring may be operational at a time. As such, maintenance may be done on one of the rings while the other is in operation. Debarking rings may have varying sizes and shapes independent from each other. Each debarking ring may further have its own frame, actuator and control and motorization modules. A sliding system, supported by a frame, may further direct the lateral displacement of both rings. Also presented is a method of processing logs through the debarking ring apparatus.

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.

In various embodiments, a feeding device may comprise a support having feed cylinders arranged in a free end of a respective supporting arm and driven in rotation, wherein the supporting arms in a supported end are journalled in the support on shafts extending in parallel with each other and are pivotable about the shafts between a home position and a pivoted work position, and wherein the supporting arms are mutually connected to each other via a system of articulated links and by means of the links are forced to pivot jointly about their respective shafts, and a movement damping element, which is separate from the support, is integrated in the system of links and independently from the support configured to brake the return movement of the supporting arms from the pivoted position.

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.
