Method for determining an angular orientation of a log (2) about one of its longitudinal development axes, comprising a first generation step, during which one or more first digital images are generated of the lateral surface of the log placed in a reference position, using one or more first digital photographs, a second generation step, during which one or more second digital images are generated of the lateral surface (1) of the log (2) placed in a second position using the one or more second digital photographs, a step of comparing the one or more second digital images with the one or more first digital images, and a step of determining the angular orientation of the log (2) in the second position with reference to a reference angular orientation of the log (2) in the reference position, based on information related to the first digital images and the second digital images for which a match was identified. Also claimed is a device which can implement is programmed to perform the following of the steps described above: the second generation step, the comparison step and the determination step.

There is provided a feed roll assembly according to one aspect. The assembly includes a feed roll and an elongate mount coupled to and extending radially outwards from the feed roll. The assembly includes an elongate mount with a recessed region extending from a distal edge towards a proximal edge thereof, extending from a first face towards a second face thereof, and extending between a pair of spaced-apart ends thereof. The assembly includes an insert shaped to matingly engage with the elongate mount via the recessed region of the elongate mount.

There is also provided a feed roll assembly according to another aspect. The feed roll assembly includes a feed roll, an insert and an elongate mount that couples the insert to the feed roll. The elongate mount is shaped to enclose a proximal edge, a backing face and spaced-apart ends of an inner portion of the insert.

A device for processing logs, comprises a deicing apparatus (11), a debarking apparatus (22), arranged downstream of the deicing apparatus, a thermal camera (30), arranged to acquire a thermal image of at least one log downstream of the debarking apparatus, and a processing device (40). The processing device (40) is configured to receive the thermal image from the thermal camera, to process the thermal image to determine a log surface temperature, and to provide a deicing control signal to the deicing apparatus (11) based on the log surface temperature. A method of processing logs is also disclosed.

A chipping machine includes a debarking assembly, a chipper assembly, and a log advance system to conveys logs through the chipping machine and into contact with the debarking assembly and chipper assembly. A rotating chipper disk cuts chips from the log. A housing encloses the chipper disc and includes a spout that provides an exit path for chips out of the housing. The chipper assembly includes a first path for collecting bark and directing bark out of the machine. A second path that is separate from the first path collects trash and directs the collected trash to first path and out of the machine. An inlet of the second path is an opening formed in a base of the housing. The second path includes a chute onto which trash falls and then slides under the force of gravity to the first path.

A method for characterizing undebarked wooden logs and computing optimal debarking parameters in real time is provided. The method comprises a scanning device upstream of a debarker for providing data, usually in the form of images, to a deep learning algorithm model. The model may be trained with human assistance or not to detect and identify, with an acceptable amount of certainty, characteristics of undebarked logs. The characteristics are used in an optimization software and classified in an index table. The index table is used to determine optimized parameters for debarking the log.

A feed roll comprises a roll having a rotary axis, flutes fixed on the roll, mounts fixed on the roll between the flutes, each mount having a seat spaced apart from the outer surface of the roll and replaceable flute elements detachably and matingly engaged in the seats of respective mounts and extending outward beyond the mounts. The replaceable flute insert element comprises an elongated plate body having an inner longitudinal edge, an outer longitudinal edge, and a backing face extending between the inner longitudinal edge and the outer longitudinal edge and the inner longitudinal edge and the backing face configured to matingly engage the seat of the mount. The flute insert element further comprises the outer longitudinal edge being formed with a traction element and the plate body having a plurality of bolt holes therethrough for registering with the bolt holes of the mount element when the plate body and the seat are matingly engaged.
