  • Method for making gasket including spherical stop means and vulcanized in-situ
    Patent number: 4196162
    Abstract: A process for the production of seals between surfaces operating at elevated temperatures is disclosed wherein a vulcanizable elastomer mixture is vulcanized by the heat transferred from the surfaces, and by the pressure created by adjustment of the space between the surfaces. In the invention, spacers are arranged between the surfaces to determine the final position thereof and hence the thickness of the seals and the pressure resistance of the spacers is higher than that of the elastomer mixture before or during vulcanization.
