Abstract: An apparatus for attaching a tire component member to a rotating toroidal green case includes support shafts whose axes are located substantially in a plane including a rotational axis of the green case. Stitching rollers are supported by the support shafts and rotatable about the axes of the support shafts, respectively. An urging device moves the stitching rollers toward the green case to urge outer circumferences of the stitching rollers against the tire component member. A swing device serves to swing the stitching rollers to continuously move contact points of the stitching rollers with the tire component member from an axially inside to an axially outside, to attach the tire component member to the outer surface of the green case.

Abstract: There is provided a method of manufacturing a tire wherein a uniformity of a tire having a reinforcing rubber layer of substantially a crescent-shaped section between a carcass and an innerliner and capable of mainly running at a run-flat state is improved by transferring a carcass band prior to turning of a carcass member around a bead core to a green tire building drum of a cylindrical form from outside in a radial direction, holding the bead core by the green tire building drum, deforming a main body portion of the carcass, turning a turnup portion thereof, attaching an innerliner rubber 12 onto an outer periphery of a first band building drum in a cylindrical form, relatively reducing a size of a reinforcing rubber overlap region of the innerliner rubber 12 every axial position by two times a thickness of the reinforcing rubber substantially corresponding to such a position as compared with a reinforcing rubber non-corresponding region, and then attaching a reinforcing rubber 13 onto the relatively size-reduced outer periphery of the reinforcing rubber overlap region of the innerliner rubber.

Abstract: Bead wires 4 are set at both ends of a carcass ply 2, to form bead portions 5 and 5. Then, a carcass body 6a incorporated with a toroidal BT band 9 around the outer periphery portion is mounted on a forming drum 13 around which side rubbers 20 are mounted through bladders 16 and 17 at the positions corresponding to the bead portions 5 and 5. Thus, by expansion of the bladders 16 and 17, the side rubbers 20 are press-contacted with both the sides of the carcass body 6a.
