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.
