Abstract: <P>PROBLEM TO BE SOLVED: To prevent a rubber tube before vulcanization from becoming inflated one-sidedly by its own weight by retaining the rubber tube in a flat crosssectional shape when inflated.  <P>SOLUTION: An unvulcanized rubber tube 50 is arranged between an inner peripheral ring 30 and an outer peripheral ring 36 and an inner pressure is applied to the rubber tube 50. Since the gap between the inner peripheral ring 30 and the outer peripheral ring 36 is narrowly set, the inflation of the rubber tube 50 is controlled by the inner peripheral ring 30 on the inner peripheral side and by the outer peripheral ring 36 on the outer peripheral side and thus the rubber tube 50 is retained in a flat shape.
