Abstract
This invention provides a method for manufacturing a tire in which the time necessary for the manufacture can be reduced without deteriorating uniformity in manufacturing the tire by a strip-build process. The method for manufacturing the tire comprises discharging a strip rubber (S) having a predetermined sectional shape by rubber discharging devices (A, A) while rotating a molding drum (B), and successively winding the discharged strip rubber (S) around the molding drum (B) to mold the rubber into a tire shape. The method comprises the step of disposing, around the radial direction of the molding drum (B), at least two rubber discharging devices of a first rubber discharging device (A) and a second rubber discharging device (A) in such a state that the phase is shifted in the circumferential direction, and conducting winding in such a state that a first strip rubber (S) discharged by the first rubber discharging device (A) and a second strip rubber (S) discharged by the second discharging device (A) are overlapped with each other by a predetermined degree in the widthwise direction of the molding drum (B).
