    (54) Device for axial engagement and disengagement of logs of wood in veneer cutting machines


    (57) A device for axial engagement and disengagement of one end of a log of wood rotating in a veneer cutting machine comprises a gripping claw (13), having a plurality of teeth (10) which penetrate into the wood, disposed on a rotating shaft (15). The rotating shaft (15) is axially movable by hydraulic means to enable the gripping claw (13) to carry out the movement towards and away from the end of the log. Housed inside the shaft (15) is a piston (20), which acts upon a pusher (22) in the gripping claw (13), in order to desengage teeth (10) from the end of the log, when the shaft (15) is retracted.
