Abstract: A system and method for detecting the origin of wooden planks in a sawmill is provided. The method scans surfaces of processed planks and, with the help of an AI algorithm comprising a deep-learning algorithm, determines the origin of said planks based on analysed parameters of the planks. The parameters used in the analysis are mainly properties of tool marks and the resulting analysis provides tools and equipment used. The deep learning algorithm may be in a self-learning mode or in a supervised training mode.

Abstract: A Variable Opening Reducer (VOR) for chipping excess fibers on a piece of wood periphery is described, the VOR comprising an infeed portion for securing and moving the piece of wood, along a longitudinal log axis thereof, inside the VOR, a chipping portion disposed sequentially after the infeed portion for receiving therein the piece of wood and for chipping and removing peripheral sections of the piece of wood, the chipping portion comprising a plurality of cutting tools, each of the cutting tools being adapted to revolve about a rotation axis thereof that is substantially perpendicularly located in respect of the longitudinal log axis of the log, each of the cutting tools being radially located in a position interfering with the piece of wood periphery to chip and remove excess fibers and an outfeed portion, disposed after the chipping portion, for receiving, securing and moving the piece of wood along the longitudinal log axis thereof A kit and a method of use thereof are also presented in the present appl

Abstract: 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.

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.
