Process for forming an annular member by extruding a thermoplastic profiled strip at an elevated temperature. Prior to cooling the strip, the still-molten ends undergo in-line compression molding to form an annular member having a joint section. The cross-section of the annular member is continuous in the joint section and the remainder of the body. Preferably, the extrudate may contain a thermoplastic elastomer, more preferably a thermoplastic vulcanizate formed by a dynamic vulcanization process. During the extrusion and compression molding processes, the extrudate may be supported on a rotatable turntable, or alternately on a rotatable molding cylinder.

Process for pipe seal manufacture

The present invention is directed to an annular gasket for providing a fluid-tight seal between an inner pipe and an outer pipe, when the pipes are in a relative surrounded and surrounding relationship. The gasket includes a gasket portion configured to sealingly engage the inner and outer pipes when the pipes are in a relative surrounded and surrounding relationship. The gasket includes a low coefficient of friction surface which is applied to the gasket portion. The gasket may be formed by a method in which a low coefficient of friction film is inserted into a mold before injection of compounds used to form the gasket.
