ABSTRACT:
An apparatus is provided for controlling the raising and lowering of a cutting head assembly of a horizontal bandsaw machine. The apparatus comprises a sensing member for sensing the top surface of a workpiece to be cut and an actuating device which is operatively coupled to the sensing member. The actuating device switches from a first state to a second state when the sensing member senses the top surface of the workpiece. A carrier device is operatively coupled to the actuator wherein the position of the carrier is movable with respect to the cutting edge of the blade of the bandsaw when the actuator is in the first state and the position of the carrier is fixed with respect to the cutting edge of the bandsaw when the actuator is in the second state. A detector is mounted on the cutting head assembly for movement therewith such that the detecting member contacts the carrier device upon the raising of the cutting head wherein upon contact of the detector and the carrier device, the detector provides a signal for stopping the further raising of the cutting head.
