Patent ID: 8465610

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 during the winding; setting a flattening roll such that, as seen in a plan view of a roller of the flattening roll, an extending direction of the rubber strip, at a point at which the strip is passed between the flattening roll and the rigid core or the building drum, is not perpendicular to an axis of rotation of the roller of the flattening roll; 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, the flattening roll moving in a direction opposite to a moving direction of the rubber strip winder which direction is defined during helical winding of the rubber strip on the rigid core or the building drum; and rotationally driving the roller of the flattening roll at a rotational speed different from that of the rigid core or the building drum.
