Abstract

A system for punching metal sheets and for stacking metal sheets in the appropriate punched pattern, particularly for electric machines, has a die for punching the metal sheets, a die plate cooperating with the die, and a guiding device for guiding the punched metal sheets below the die plate. The guiding device has at least two clamping elements. The clamping elements are provided for clamping the punched metal sheets on their circumference and thus forming a stack branch-off which permits an uninterrupted punching during the discharge of the metal sheet stack.
