Abstract: A band saw machine is provided with a fixed and movable blade guide arm which are set apart by a distance which is proportional to the width of workpiece to be cut. A detector mounted on one of the guide arms senses the lateral deviation of the saw blade during cutting and a control circuit outputs a termination signal to shut down the machine when the deviation is larger than a desired maximum value. When a workpiece of a different width is to be cut the guide arms are reset apart by a distance proportional to the width of the new workpiece and a detector is provided which senses the change of distance between the guide arms and outputs a signal to a revising circuit. The revising circuit then revises the maximum value of deviation to be allowed based on the change of distance between the guide arms.
