    Abstract: A pruning device having a chain saw with a flexible chainbar and a double-articulated cutting chain. The chainbar has a relaxed shape of a helix for encircling a tree trunk. The double-articulated cutting chain can curve about two lateral axes so that it may follow the perimeter of the helical chainbar and cut branches from the tree. A remotely located power supply is provided on a wheeled cart for powering the chain saw and supporting and operating a support wand that supports the chain saw and raises and lowers it along the tree trunk.

    Abstract: A chain cutter for debranching and/or debarking trees in which the chain serves to carry cutter teeth and which lies, during operation, at least partly on the trunk being processed. A plurality of chain plates are mounted on the chain and provided with at least three differently shaped and ground cutter teeth. The teeth are arranged along the longitudinal axis of the chain in a repeating sequence of a spaced pair of teeth and a substantially centrally located single tooth. The spaced pair of teeth project outwardly beyond the sides of the chain.

    Abstract: D R A W I N G
    AN APPARATUS FOR DEBRANCHING AND/OR DEBRAKING FELLED TREES COMPRISING UPPER AND LOWER VERTICALLY DISPLACEABLE SUPPORTS EACH HAVING STATIONARY, ROTATABLY MOUNTED GUIDE PINIONS, INPUT PINIONS AND OUTPUT PINIONS FOR EACH OF AT LEAST TWO ENDLESS CHAIN CUTTERS PASSING BETWEEN THE SUPPORTS. TWO MOTORS ARE OPERATIVELY CONNECTED TO EACH CHAIN TO DRIVE IT IN TRACTION AND THRUST. THE INPUT AND OUTPUT PINIONS ARE ARRANGED TANGENTIALLY TO THE PERIPHERY OF THE TRUNK SO THAT THE CUTTERS RUN IN OPPOSITE DIRECTIONS ALONG OVERLAPPING, OPPOSED PERIPHERAL PORTIONS OF THE TRUNK. TENSIONING MEANS ARE ALSO INCLUDED TO APPLY TENSION TO THE CHAIN CUTTERS SO THAT THEY WILL FOLLOW THE PROFILE OF THE TRUNK DURING PROCESSING.
