Abstract
A filter element has a carrier plate with a mounting groove which extends around a filter chamber recess. A filter cloth blank, which covers this recess, has a mounting frame which is formed on and sits in the mounting groove. The filter cloth is thus positioned easily, quickly and in a crease-free manner on the carrier plate and a liquid barrier is thus obtained at the edge of the filter cloth blank.
