ABSTRACT:
A horizontal bandsaw is mounted in a tool carrier above a workpiece location. Before it starts cutting the bandsaw is tilted an angle between 3.degree. and 10.degree. and after the initial cut that angle is maintained during the rest of the cut until the intended depth of cut is reached or closely approached, when the saw tilt is removed as the structure containing the bandsaw is swung to orient the bandsaw horizontally. If the depth of cut is a complete cut through, the advantage of a minimum erosion of the center selvage of the workpiece support is assured. Mechanical limits are provided for the vertical displacement by tilt at one side of the workpiece and on that side one of the guides of the structure supporting the bandsaw has a hydraulic changeover control in which the angle of tilt is set by adjustable screw-stops which cooperate with stop plates mounted on the structure supporting the bandsaw.
