Debarking cutting member with angle that corresponds to the motion vector generated by the translation and rotation of the trunk

摘要

The present invention relates to debarking arrangement in a wood- handling device. Such a debarking arrangement is particularly applicable to be used in a harvester head of a forestry machine. The debarking arrangement comprises a member (13) arranged in the wood-handling device, extending to the surface (11) of a trunk (2) and arranged to cut bark (12) of the trunk. The member leaves a cutting trace on the bark of the trunk that is at an angle (á) relative to the longitudinal axis (9) of trunk. With the debarking arrangement, the angle substantially corresponds to the directional angle of the motion vector generated on the trunk surface by the translation and rotation of the trunk.
