ABSTRACT:
A method of manufacturing a sealing gasket on the rim of a sheet of glass has a preformed sealing gasket fixed to the rim of a glass. Polymerization is carried on in situ with a polyurethane material in a modified mold in which the preformed sealing gasket is positioned. The preformed sealing gasket also forms a sealing junction to avoid leakage of the polymer material.
