Abstract
A method for continuously vulcanizing hoses which comprises two steps: microwave vulcanization; and conventional vulcanization by heat conduction through a heating medium. A layer of heat-resistant synthetic resin which has a melting point higher than the vulcanizing temperature is provided over the outer periphery of a rubber hose in a uniform thickness. This layer is in close contact with the hose but not adherent thereto. After the resin layer is cooled and hardened, the rubber hose is heated and cured in a microwave vulcanizing tank before being subjected to vulcanization by heat conduction through a heating medium in an ordinary vulcanizing tank. After completion of vulcanization, the layer of synthetic resin is peeled off and removed.
