Abstract
A tire fabricating method and apparatus for mounting a component assembly on a drum and applying a pressing force radially inward of the drum to thereby adhere a carcass, a breaker, and a tread constituting the component assembly to one another. Around the component assembly, first and second stitch roller members are arranged at positions adjacent to each other in a circumferential direction. While the drum is rotating, a fluid cylinder is elongated so as to press the first and second stitch roller members against an outer circumferential surface of the tread, and roller elements of the respective stitch roller members are moved away from each other from a center portion of the outer circumferential surface of the tread to opposite ends thereof so as to widen a spacing between the roller elements.
