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.
Claims12
An apparatus for removing branches from and for crosscutting treetrunks, comprising
- a frame, which is adapted to be suspended from a lifting tackle over a treetrunk having a longitudinal axis extending in a predetermined, substantially horizontal direction,
- gripping means, which protrude downwardly from said frame and are movable mounted on said frame and operable to move into and out of frictional engagement with the lower half of said treetrunk to support the latter,
- branch-removing tools, which are mounted on said frame and distributed around the periphery of said treetrunk when it is thus supported by said gripping means,
- a longitudinal feeding device, which is mounted on said frame and operable to impart an axial feed movement to said treetrunk when it is thus supported by said gripping means,
- a crosscutting tool, which is on said frame and is operable to move transversely to said predetermined direction and to crosscut said treetrunk when it thus supported by said gripping means, and
- rotary turning means mounted on said frame for bringing an entire planar cross-section of said treetrunk into engagement with said crosscutting tool by imparting to said treetrunk when it is thus supported by said gripping means a rotary movement substantially about said axis.
