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.

Method of forming a gasket with enhanced sealing characteristics

A gasket assembly comprising a main gasket body and a sealing insert member retained within an opening in the body is disclosed, as is a method of making the assembly. The sealing insert member, which may comprise a sealing grommet or the like, is provided with a plurality of star-like deformable tabs at the outer periphery thereof, with each of the tabs initially formed in a generally dished configuration. The opening in the gasket body which receives the insert member includes a plurality of tab-receiving apertures at the outer edge thereof, with each of the deformable tabs respectively received within one of the apertures. Upon positioning of the insert member within the opening, each of the deformable tabs is deformed, such as by swaging between associated punches, whereby each tab is flattened and urged into engagement with the associated gasket body for retention of the sealing insert member in position.

Gasket assembly having a sealing insert member and method of forming

The construction and method of forming a wicking-resistant gasket assembly for an internal combustion engine is described. The gasket assembly includes a flat-elongated base, a layer of composite, porous gasket material on each face of the base, armor at the combustion chamber openings, and a peripheral bead of elastomeric material enveloping the edges of the gasket material sheets and the base to prevent the wicking of liquids from the gasket assembly layers outwardly through the periphery of the gasket assembly. The bead is applied to contact the free margin of the facing material and the peripheral edge of the base. The bead is preferably cured in place concurrently with the lamination and curing of the facing materials.
