Abstract
A flat sealing plate for combustion engines and a method for manufacturing same are disclosed. The sealing plate comprises a layer of soft sealing material consisting of mineral base compounds as well as of a binder material being at least partially vulcanized. A first and a second metallic foil are glued on both sides of the soft sealing material layer. For the manufacture of such sealing plate calender rolls are used to calender the sealing material on the first foil and additional rollers are then used to laminate the second foil on the opposite side of the sealing material layer.
