Abstract:
1. A debarker for removing bark from logs comprising: a plurality of rotating debarking shafts arranged side-by-side and in a debarking plane, said shafts being parallel to an advancing direction of the logs through the debarker and include debarking features projecting from an outer shaft surface; the debarking shafts in the debarking plane forming a support surface for the logs in the debarker, the debarking shafts rotating in a direction that deflects the logs and removed bark upward in a direction substantially transverse to the advancing direction; an offset debarking shaft parallel to and adjacent one of the debarking shafts in the debarking plane, the offset debarking shaft including debarking features and the offset debarking shaft being offset in a direction upward from the debarking plane; a guiding surface parallel to and upwards of the offset debarking shaft, and a slot between the guiding surface and the offset debarking shaft, wherein the slot converges along a direction aligned with a rotational direction of the debarking shaft.
