Abstract
In the manufacture of a gasket wherein a rigid, compression-limiting component is formed by molding in situ against the side of a preformed compressible gasket component to bond therewith, a narrow channel is pressed into the face of the gasket component during the molding operation. The gasket material is permanently deformed in this channel, which runs on the gasket face adjacent the edge of the side to which the rigid component is molded. The channel provides a durable, reproducible demarcation between the compressible and rigid components. Formation of this channel in molding has been found to prevent flashing of the material being molded, over the gasket face.
