Abstract
A method of forming a gasket with an accurately aligned and deposited sealing bead and embossment arrangement. The method comprises providing a deformable gasket body having two spaced apart major surfaces. The next step involves applying a relatively imcompressible sealing material against one of the major surfaces on the gasket body with sufficient pressure and in a manner deforming both of the major surfaces of the gasket body. The deformation of the gasket body defines an embossment comprising a projection extending outwardly from one major surface and a substantially corresponding indentation extending inwardly from the other major surface. Besides creating an embossment, sealing material remains in and fills the indentation to provide support for the embossment. Another step in the process involves curing the sealing material filling the indentation in the gasket body.
