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.
