Abstract
A filter for the filtration of extraction beverages includes a disk having a plurality of apertures through which the beverage extracted from the material to be extracted passes form the afflux side to the efflux side. Each aperture is formed by cut edges in the disk and by bending a cut edge away from the surface of the disk to form a roof-shaped dome. The filter is formed by a single punching, bending and embossing operation without scrap slug being produced.
