Patent ID: 7617854

Claim:
A method for manufacturing a pneumatic tire including an entire tread rubber or a cap layer, said entire tread rubber or cap layer being formed by using an annular wound body obtained by winding ribbon-like non-vulcanized rubber strips in a spiral manner, and the method including: a step of fixedly attaching a winding start point of a first rubber strip and a winding start point of a second rubber strip to an object to be wound at positions located further inward in a width direction than the respective sides of the wound body, a winding step for forming the entire tread rubber or the cap layer, comprising a first winding step for forming a first layer by spirally winding the first rubber strip towards one side up to the one side and by spirally winding the second rubber strip towards the other side up to the other side, and a second winding step for successively forming a second layer outside of the first layer by turning the first rubber strip up at the one side and spirally winding the same towards the other side without cutting the same at the one side and by turning the second rubber strip up at the other side and spirally winding the same towards the one side without cutting the same at the other side, and a step of fixedly attaching a winding end point of the first rubber strip and a winding end point of the second rubber strip at positions located further inward in the width direction than the respective sides of the wound body, wherein said winding start point of the first rubber strip is provided between the other side of the wound body and a width center of the wound body such that the first rubber strip, at its winding start point, has a side surface, on the side thereof that faces the one side of the wound body, located at the width center, and the winding start point of the second rubber strip is provided between the one side of the wound body and the width center of the wound body such that the second rubber strip, at its winding start point, has a side surface, on the side thereof that faces the other side of the wound body, located at the width center so that the first rubber strip and the second rubber strip intersect with each other at the width center of the wound body in the first winding step.
