PROBLEM TO BE SOLVED: To provide a tire member manufacturing method which allows air to escape sufficiently by preventing a through hole formed once by a pricking device from being closed again and can manufacture a tire having stable performance.SOLUTION: A tire member manufacturing method includes a pricking step in which a through hole is formed in a sheet-shaped tire member by using a pricking device, and a cooling step in which the pricked tire member is cooled by using a cooling apparatus set immediately behind the pricking device. In the tire member manufacturing method, the cooling apparatus is a roller the inside of which is filled with a circulated cooling medium. In the tire member manufacturing method, the penetration ratio of the tire member is controlled to be a prescribed value by controlling the temperature of the cooling medium. In the tire member manufacturing method, a transportation step for transporting the tire member by a belt conveyer is provided at the downstream side of the cooling step, and the belt conveyer is formed of a material whose thermal conductivity is higher than that of the tire member. |
