摘要： A method of fabricating a rubber double-toothed belt wherein the unvulcanized rubber thereof is firstly heat treated so as to define a first toothed portion of the belt without substantial vulcanization thereof. The preform is then entrained about pulleys and a pair of heated molds engaged with both the toothed portion and the nontoothed outer portion of the belt to place the preform under pressure at a vulcanization temperature for sufficient time to cause the outer rubber portion of the preform to flow outwardly and define the outer teeth of the final belt concurrently with the vulcanization of the double-toothed belt construction. The parameters for controlling the heat treatment to provide the configurational retention without substantial vulcanization of the preform rubber are disclosed.
