Abstract:
Provided are a method for manufacturing a pneumatic tire, and a molding device, whereby, when a tire constituent member is layered on the outer surface of a molding drum and a green tire is molded, a reinforcing wire extending in the width direction of the drum can be efficiently arranged with good precision in a predetermined position continuously in the circumferential direction of the drum. An arranging unit 4 is caused to move relative to a molding drum 2 in the circumferential direction of the drum, and a one-side step and an other-side step are repeated, the one-side step for delivering a predetermined length of a reinforcing wire M3 in a folded state from the widthwise center part of the molding drum 2 toward one widthwise side thereof using the arranging unit 4, and pressure-bonding the reinforcing wire M3 to an inner liner M1 of an outer surface 2s of the molding drum 2, and the other-side step for delivering a predetermined length of the reinforcing wire M3 in a folded state from the widthwise center part of the molding drum 2 toward the other widthwise side thereof after a predetermined length of the reinforcing wire M3 is delivered toward the one widthwise side as described above, and pressure-bonding the reinforcing wire M3 to the outer surface of the inner liner M1.
