Abstract: The present tree bark removing apparatus is suitable for mounting on a carriage for mobile use and also for stationary installation, for example, in a saw mill. A frame structure supports two rows of driven wheels which form a tree trunk passage. The wheels are, for example, driven by a frictional contact with a drive roller extending along and in contact with the two rows of wheels. A tool supporting bridge carries a tiltable platform, which in turn has secured thereto a cantilever arm, the free end of which supports the tool head. The platform is tiltable by power means so that the free end of the cantilever and thus the tool may be brought into contact with a tree trunk, which is moved past the tool by the rotating wheels. For this movement the wheels extend at an angle relative to the longitudinal axis of the apparatus to propell the tree trunk past the tool whereby the tree trunk rotates simultaneously with the longitudinal movement.
