Patent ID: 7416625

Claim:
A method for manufacturing a tire, comprising: building a desired green tire by helically winding and laminating a rubber strip on a rigid core or a building drum; moving a rubber strip winder so that the rubber strip winder is being constantly located at a given position with reference to the rigid core or the building drum; setting a flattening roll such that roller of the flattening roll is rotationally driven to have a rotational speed different from that of the rigid core or the building drum, the difference in rotational speeds between the rigid core or the building drum and the roller of the flattening roll being set to be greater than 0% to about 30% of a rotational speed of the rigid core or the building drum; and flattening a projection of a stepped portion produced by one portion of the rubber strip and another portion of the rubber strip overlapping thereon under pressure by the flattening roll, a surface of a roller of the flattening roll being moved so that the roller of the flattening roll is being constantly located at a given position with reference to the rigid core or the building drum.
