A method for manufacturing a resin-impregnated endless belt structure is carried out on an apparatus (60) having an outer cylinder (66) and an inner cylindrical surface that is coaxial with a smaller radius cylindrical mandrel (64). An endless base structure is disposed with the outer cylinder (66) on the inner cylindrical surface. The cylindrical mandrel, having an inwardly curved nose (68), is then inserted into the outer cylinder (66) forming a nip (70) between the curved nose (68) and the inner cylindrical surface. Polymeric resin is dispensed continuously into the nip (70) while the cylindrical mandrel is gradually moved into the outer cylinder (66). The nose forces the resin into the endless base structu re and expels air bubbles while forcing the endless base structure against the inner cylindrical surface. After the polymeric resin 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 of the apparatus (60).
