Abstract: An arrangement for optimizing the unproductive motions of a holdfast-beam in a machine that cuts sheets of material that are stacked on a bench. A hydraulic beam descends onto the stack of sheets to hold them fast before they are cut, and rises again after the sheets have been cut. A definite distance between the holdfast-beam and the material that has been cut is determined while the beam rises off the sheets of material. The rise of the holdfast-beam is terminated when a definite distance is determined.

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.

Abstract: A method for optimizing the cutting of sheets of material that are stacked on a bench in a cutting machine. Before cutting the sheets, a beam descends to hold the sheets fast while guillotine blade descends and cuts the sheets. After the sheets have been cut, the blade and beam are lifted, with the lower edge of the beam following the sharp edge of the blade. A definite distance between the blade and the top of the stack is determined while the blade rises after cutting the sheets. The rise of the blade is terminated at the upper end of that distance, which is determined by a pick-up mounted stationary on the holdfast beam. This pick-up detects the position of the rising blade in relation to the holdfast beam.
