Method for producing belt, and cylindrical mold and crosslinking apparatus used therefor

A method for producing a belt, the method comprising:

• providing a cylindrical mold which is hollow, made of metal, and having a mold center axis that extends through the cylindrical mold between axial ends of the cylindrical mold, a shaped structure which is hollow, having a cylindrical shape, and having a structure center axis that extends through the shaped structure between axial ends of the shaped structure, a rotation mechanism that rotates about a mechanism center axis extending in a vertical direction and configured to rotatably support a lower end of the cylindrical mold, and an electromagnetic induction coil configured to heat the cylindrical mold through electromagnetic induction;
• setting the shaped structure inside the cylindrical mold, wherein the shaped structure and the cylindrical mold with the shaped structure set therein are disposed such that the mold center axis and the structure center axis are extending in the vertical direction;
• and
• molding a cylindrical belt slab by heating the cylindrical mold by the electromagnetic induction coil, while the cylindrical mold is rotated by the rotation mechanism and the shaped structure is pressurized from inside, wherein
• after having been heated, the cylindrical mold is cooled through direct ejection of cooling water to an outer periphery of the cylindrical mold.
