ABSTRACT:
(1) During vulcanization, a tire clamping device C is released. (2) After vulcanization has been completed in one tire mold M, the tire mold clamping device C on the side of this tire mold assembly M is operated, so that an upper mold M.sub.2 is connected to an upper mold attaching plate 1. (3) The upper mold attaching plate 1 is raised and the upper mold M.sub.2 connected to the upper mold attaching plate 1 is opened, while on the side of the other tire mold assembly M, vulcanization is continued with the upper mold M.sub.2 being closed. (4) On the side of one tire mold assembly M in which vulcanization has been completed, the removal of the vulcanized tire and the insertion and forming of an unvulcanized tire are carried out in sequence by the procedure similar to the conventional one, and then the upper mold M.sub.2 is closed. Then, a predetermined heating/pressurizing medium is supplied to start vulcanization. For the period from this time to the completion of vulcanization, the tire mold clamping device C is released. (5) On the side of the other tire mold assembly M as well, when vulcanization is completed and the time of opening/closing the upper mold M.sub.2 is reached, the upper mold M.sub.2 is opened and closed by the same procedure.
