  • Method of manufacturing a flat gasket
    Patent number: 7913386
    Abstract: Flat gasket comprising a first sheet metal layer consisting of a spring steel and a second sheet metal layer consisting of a ductile steel, the first layer being provided with a sealing bead, and the second layer being provided in an edge area bordering on an edge of the layer with a thickened zone as supporting element for receiving pressing forces; to increase the design possibilities for such a supporting element, the latter is formed by at least one elongate arch of the second layer, which is stamped into the edge area of the second layer and extends approximately parallel to the free edge of the edge area, the arch being compressed in such a way that the metal volume of the supporting element is at least three times the total hollow space volume which the supporting element and two tangential planes abutting on the latter and extending parallel to the plane of the second layer include between them.
