ABSTRACT:
An arrangement for cutting stacked sheets of material resting on a bench. A hydraulically actuated holdfast beam descends onto the material to be cut, and the cutter travels perpendicular to the surface of the bench adjacent to the holdfast beam. A sensor operates during the cutting in conjunction with a circuit that controls the holdfast beam, and emits a signal to reduce the beam's holdfast force. The sensor is mounted below the holdfast beam and outside its effective surface that comes into contact with the material being cut. The distance between the sensor and the effective surface of the holdfast beam equals the distance between a lower edge of the holdfast beam and an upper edge of the stacked material that is being cut.
