Furthermore, the holding device is adapted to cause the log to rotate. A rotatable milling unit (5) has peripherically or externally located processing elements and is located for processing the protruding end portion of the log from below. The holding device has bearing members (6, 6a) operable for moving the log between an upper position and a lower position. The bearing members are located in such a way relative to the milling unit that a log resting on the bearing members on lowering thereof will enter into contact with the milling unit, which is stationarily mounted to a frame of the machine. |
