Abstract:
PROBLEM TO BE SOLVED: To adjust the length of a rubber member to a specified length while dissolving width variation in the longitudinal direction of the rubber member when winding the rubber member on a molding drum.SOLUTION: A tire manufacturing method is a tire manufacturing method in which a rubber member W is stuck on a molding drum 60 to manufacture a tire. Included are a member width measurement process in which the width of the rubber member W is measured upon sticking the rubber member W on a molding drum 60 and a member length adjustment process in which the length of the rubber member W is adjusted by elongating the member length in the longitudinal direction to a specified length on the basis of the measured rubber member W width. In the member length adjustment process, the amount of elongation of the rubber member W is made larger in the wider width part than in the narrow width part of the measured rubber member width W.
