Abstract:
A method of processing material sheets, which comprises:providing material sheets each having a bottom sheet end with a bottom sheet margin; processing the material sheets in strips in each case at the bottom sheet end in working steps in an X-direction, and thereby stamping out cut parts from the respective lowermost material-sheet strip and ejecting the cut parts and forming a stamped-grid strip; thereafter progressively cutting respective stamped-grid strips from the material sheet parallel to a bottom sheet margin and removing the strip grid after complete separation; wherein the processing step comprises alternately processing two material sheets in strips, with a first material sheet being worked cyclically along a strip in the X-direction, a second material sheet being fed in the X-direction, and the second material sheet being subsequently worked cyclically along a strip, while the first material sheet, now reduced by one material strip, is returned directly past a processing space counter to the X-direction into a ready position, is adjusted in a Y-direction by a strip depth to be worked, and then cyclically follows the second material sheet in the X-direction, and wherein a further strip is worked cyclically from the first material sheet, and a new material sheet to be processed is made to follow the respectively last strip of each worked material sheet in the X-axis direction.
