ABSTRACT:
A hydraulic tensioning apparatus for the blade of a bandsaw machine. The blade is trained around a pair of wheels, one of which is mounted on a carrier which is movable relative to the other wheel. The carrier is acted upon by a double acting hydraulic motor, the operation of which is controlled by a manually adjustable valve. A check valve blocks the escape of hydraulic fluid from the motor when the manually adjustable valve is set to the "tension" mode.
