Abstract
The invention relates to an apparatus and a method for making window cutouts (22) in a frame material (20) in web form for a membrane electrode unit, wherein, at least in some section or sections, the frame material (20) is processed as a material combination with a carrier web (30), wherein a contour cut (50) that cuts through the frame material (20) is made in the frame material (20) from an opposite side of the frame material (20) to the carrier web (30), while forming a punching chad (201), wherein the contour cut (50) is made without cutting through the carrier web (30), wherein the punching chad (201) is separated from the material combination using a rotatable roller (40, 40a) having a suction opening (402), wherein a suction force is applied to the punching chad (201) via the suction opening (402), with the result that the punching chad (201) is detached from the carrier web (30) by use of the suction force and transported away from the material combination using the roller (40, 40a). The invention furthermore relates to the use of a rotatable roller in making window cutouts.
