The invention relates to an arrangement at the discharge end of a debarking machine (12) for the preliminary debarking of logs (2) prior to a separately performed final barking and for the expulsion of at least some of the removed barks from a wood flow passing through the debarking machine. The debarking machine (1) has its discharge side provided with an extension (5), continuing from the lower section level of the support surface of the debarking machine used for bearing the logs (2), and guiding the logs (2) discharging out of the debarking machine (1). The extension may include a variable speed conveyor (7), varying the speed of which influences the admission rate of logs into the debarking machine and the dwell time of logs therein.
An arrangement at the discharge end of a debarking machine (1), said debarking machine (1) being intended for the decortication or pretreatment of logs (2) for separately performed final barking and for the expulsion of at least some of the removed barks from a wood flow passing through the debarking machine, said debarking machine comprising a number of rotatable debarking shafts (3) extending parallel to an advancing direction (A) of the logs (2) to be fed therethrough and provided with a number of teeth (4) extending beyond the circumferential surface of the shaft and adapted to strip bark off the presently processed logs transversely to the lengthwise direction of the logs (2) and at the same to convey the log transversely relative to said shafts (3), and said shafts (3), together with the teeth (4) thereof, being adapted to constitute at least a part of a support surface, upon which the presently processed logs (2) travel through the debarking machine (1), characterized in that the debarking machine (1) has its discharge side provided with an extension (5), continuing from the lower section level of the support surface of the debarking machine used for bearing the logs (2), and guiding the logs (2) discharging out of the debarking machine (1), which extension (5) has its support surface for guiding the logs (2) adapted to be at least substantially parallel to the support surface of the debarking machine (1) used for guiding the logs (2).
A debarking machine for removing bark from logs advancing through the machine toward a discharge end in a first direction, said debarking machine comprising:
A debarking station for debarking logs, said station comprising:
