Abstract

A tree feeding device of a tree handling machine has a saw (8) for cross-cutting of a tree trunk, a conveying unit (2) for moving the tree trunk, an actuator (4) for positioning the conveying unit (2) as well as delimbing blades (6) for delimbing the tree trunk. The conveying unit (2) has a rotatable structure with peripheral, substantially rigid surface adapted to support a continuous contact member, which transmits force between the rotatable structure and the tree trunk. The force acting between the rotatable structure and the tree trunk is adapted to be transmitted directly between the peripheral surface and the continuous contact member of elastic material, which is in direct contact with the peripheral surface and capable of moving freely in relation thereto in a manner determined by the load acting on the elastic material.
