Abstract
A method of producing a radial tire for a construction vehicle, the method enabling a vast reduction in facility costs. A first green tire is formed in a first step molding machine and then removed from it. After that, a vulcanizer bladder unit is installed on the tire. The tire is inflated by the vulcanizer bladder unit and then again placed in the first step molding machine with the vulcanizer bladder unit installed. After that, on the first step molding machine, belts and tread rubber are adhered to the outer periphery of the tire to form a completed green tire. Then the completed green tire, with the vulcanizer bladder unit, is assembled in a vulcanizing mold for vulcanization.
Claims4
A method of producing a radial tire for a construction vehicle,
- in which a first green tire is removed from a first step molding machine after the first green tire is formed by the first step molding machine;
- a vulcanizer bladder unit is installed to the first green tire thus removed, and the first green tire is inflated by the vulcanizer bladder unit;
- subsequently the first green tire is once again placed in the first step molding machine while the vulcanizer bladder unit is still being installed to the first green tire;
- belts and tread rubber are adhered to the outer periphery of the first green tire on the first step molding machine to form the first green tire into a completed green tire;
- and the completed green tire is assembled into a vulcanizing mold while the vulcanizer bladder unit is still being installed on the completed green tire to be vulcanized.
