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.
An apparatus for making window cutouts in a frame material in web form for a membrane electrode unit, wherein a punching device and a detachment device are provided, wherein the frame material can be fed to the punching device as a material combination with a carrier web, wherein the punching device is configured to make in the frame material a contour cut that cuts through the frame material from a side of the frame material opposite to the carrier web, while forming a punching chad, without cutting through the carrier web, and wherein the detachment device is configured to separate the punching chad from the material combination, wherein the detachment device comprises a rotatable roller and a vacuum device, wherein a suction opening that can be connected fluidically to the vacuum device is provided on the roller, and wherein the vacuum device is configured to apply a suction force to the punching chad via the suction opening as the roller rotates in order to detach the punching chad from the carrier web by use of the suction force and to transport it away from the material combination using the roller.
A method for making window cutouts in a frame material in web form for a membrane electrode unit, wherein, at least in some section or sections, the frame material is processed as a material combination with a carrier web, wherein a contour cut that cuts through the frame material is made in the frame material from a side of the frame material opposite to the carrier web, while forming a punching chad, wherein the contour cut is made without cutting through the carrier web, and wherein the punching chad is separated from the material combination, wherein the punching chad is separated from the material combination using a rotatable roller having a suction opening, wherein a suction force is applied to the punching chad via the suction opening, with the result that the punching chad is detached from the carrier web by use of the suction force and transported away from the material combination using the roller.
Use of a rotatable roller in making a window cutout in a frame material in web form for a membrane electrode unit, wherein the frame material can be fed to the roller as a material combination with a carrier web, wherein a suction opening that can be connected fluidically to a vacuum device is provided on the roller, wherein, as the roller rotates, a suction force is applied via the suction opening to a punching chad arranged in the window cutout in order to detach the punching chad of the frame material from the carrier web by use of the suction force and to transport it away from the material combination using the roller.
