Method for manufacturing unvulcanized tire and apparatus for manufacturing the tire

Abstract

When a stitching roll is allowed to act on a tread rubber member to attach the tread rubber member to an unvulcanized tire, lateral displacement of the tread rubber member is prevented. In a method for manufacturing unvulcanized tires by attaching a tread rubber composite (40) to an unvulcanized tire (55), the tread rubber composite (40) is disposed on the outer circumference of the unvulcanized tire (55) that is disposed on the molding drum (50) and is swelled into a toroidal shape, and, while the molding drum (50) is rotated, a rotating stitching roll (45) is pressed against a tread rubber member (42) of the tread rubber composite (40) to press-bond it to the unvulcanized tire (55). At this time, the outer-peripheral rotation speed of the stitching roll (45) is controlled such that it is substantially equal to the outer-peripheral rotation speed of the above-described tread rubber member (42).
