Abstract

A rubber ring-shaped seal is formed by inserting one or more layers 14, 16 of fiberglass cloth against a surface in the mold cavity of a suitable ring-shaped mold. A tubular ring- shaped insert 18 formed from semi- cured silicone rubber with a garter or helical coil spring 22 inside the bore of the tubular insert, is placed in the mold cavity over the fiberglass cloth. The tubular insert is sized so the coil spring inside causes the insert to contract and exert a compressive force on the fiberglass cloth. This holds the cloth against the surface in the mold cavity. A ring of uncured silicone rubber is placed in the mold cavity and the mold cavity is then closed and subjected to heat to cure the rubber. The resulting seal has fiberglass cloth covering a surface of the seal with the helical coil spring inside the seal held in spaced relationship from the inner surface of the fiberglass cloth. <IMAGE>
