An arrangement for the feeding and guiding of tree trunks in conjunction with the delimbing of the trunk operates with moving feed belts 22 arranged opposite one another on either side of the trunk, which feed belts drive the tree trunk by friction in its longitudinal direction through a delimbing unit, where branches are removed from the tree. the feed belt is in the form of an endless belt which is attached along its lateral edges 23 to drive chains 20 engaging with toothed rings 24 on two separate feed wheels 7. A rectilinear section of the feed belt is held under pressure in flexible contact with the trunk 1 as friction is developed over a relatively large area. The large friction surface between the feed belt and the trunk means that the necessary force for feeding the trunk can be achieved without the risk of damage to the surface layer of the trunk.
