0,680-018 METHOD OF MAKING MULTI-DENSITY COMPOSITE GASKETS ABSTRACT OF THE DISCLOSURE A method of forming a multiple density gasket is disclosed which includes the steps of moving both a first gasket material having a first lateral thickness, and a second gasket material having a second lateral thickness less than the first lateral thickness, along a path. Typically, a third gasket material is used, with the second material sandwiched between the first and third layers. The materials are compressed and gaskets are stamped from the compressed gasket material. The second material selectively forms higher density portions in the gasket. The invention simplifies the method of forming multiple density gaskets over prior art systems.
