ABSTRACT:
A method for manufacturing a resin-impregnated endless belt structure is carried out on an apparatus having an outer cylinder having an inner cylindrical surface coaxial with a smaller radius cylindrical mandrel. An endless base structure for the endless belt structure is disposed within the outer cylinder on the inner cylindrical surface. The cylindrical mandrel, having an inwardly curved nose, is then inserted into the outer cylinder forming a nip of converging geometry between the nose and the inner cylindrical surface. Polymeric resin material is dispensed continuously into the nip while the cylindrical mandrel is gradually moved completely into the outer cylinder. The nose forces the polymeric resin material into the endless base structure, and air bubbles out, while forcing the endless base structure against the inner cylindrical surface. After the polymeric resin material is cured, the endless belt structure, having a totally impregnated, air-bubble free endless base structure with a coating on its inner surface, may be obtained upon removal from the apparatus.
