Abstract: An apparatus for removing branches from treetrunks comprises a frame, which is adapted to be suspended from a lifting tackle and is provided with grippers for engaging the treetrunk from below, with a longitudinal feeding device for moving the treetrunk in its longitudinal direction, with branch-removing tools, which are spaced around the treetrunk, and preferably with a crosscutting tool, which is movable transversely to the direction of the longitudinal feed movement. In order to facilitate the longitudinal feed movement and to permit an undisturbed removal of branches at a high rate, the frame and/or the grippers or the tool carriers are provided with spray nozzles for spraying liquid, such as water or soapy water, onto the treetrunks and lines for supplying said liquid to said spray nozzles are connected to the latter.

Abstract: An apparatus for cross-cutting a treetrunk comprises gripping members which embrace the treetrunk, a feeding mechanism for moving the treetrunk in its longitudinal direction, and a saw which moves transversely to the longitudinal direction and cuts the treetrunk into predetermined lengths. One of the gripping members includes a rotatable guide roller having peripherally spaced apart teeth which engage the treetrunk. The apparatus also comprises a displacement pickup unit which ensures that the treetrunk is cut to a predetermined length. The displacement pickup unit is connected to the guide roller and detects the number of rotations of the guide roller, thereby detecting the longitudinal displacement of the treetrunk. The displacement pickup unit is located within the gripping member so that it is shielded from outside influences.

Abstract: The apparatus for removing branches from and for crosscutting treetrunks comprises a frame, which is adapted to be suspended from a lifting tackle and is provided with grippers for engaging the treetrunk from below, with a longitudinal feeding device for moving the treetrunk in its longitudinal direction, with branch-removing tools, which are spaced around the treetrunk, and with a crosscutting tool, which is movable transversely to the direction of the longitudinal feed movement and preferably consists of a circular saw. In order to increase in a simple manner the field of application of the crosscutting tool, the frame is provided not only with the longitudinal feeding device but also with a rotating device for a rotary feeding of the treetrunk.
