Abstract

The invention relates to a method and an arrangement for removing bark when handling a trunk (A) in a timber harvester, especially in connection with lopping. To remove the bark, the axis of rotation of means (1) for feeding the trunk (A) is positioned at an angle with the longitudinal axis of the trunk in such a way that the trunk is brought into rotation about the longitudinal axis during the feed movement. The arrangement further comprises means (3) for removing bark during the simultaneous rotation movement (R) and feed movement.
