    Abstract: In producing a side-reinforced type runflat tire in which side reinforcing rubbers with generally crescent-shaped sections are interposed between a carcass and an inner liner, the first drums 11a, 11b on which the side-reinforcing rubbers are to be attached are so configured that their diameter do not substantially fluctuate along the axial direction. The expanding operation of the first drum, the mutually approaching operation of the first drums 11a, 11b, and the approaching operation of the bead gripping rings 30A are synchronized. As a result, there is provided a tire and a method of its production capable of being produced by a multi-size mixed flow production system consisting of minimum equipments and of preventing air inclusions and wrinkles between the carcass member 4A and the side-reinforcing rubber 2A.

    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: An expandable tire building drum, having alternating fixed (226, 326, 426) and expanding (228, 328, 428) segments (e.g., 24 of each) in a center section (220, 320, 420) of the drum. The expanding segments are axially-extending and circumferentially spaced from one another, and are contoured (have recesses, or grooves) to accommodate tire components such as sidewall inserts. Two different mechanisms for expanding the center section are described. A first mechanism includes two wedge elements (358) which are axially moveable away from one another to expand the center section. Ramp elements (348) associated with the expanding segments (328) may thus be moved radially outward. Rubber bands (358) provide a restoring force for collapsing the center section. A second mechanism includes two guide rings (458) which are axially moveable towards one another for expanding the center section, and away from one another to collapse the center section. Overlapping links (462, 464) are provided between the guide rings and a support element (448) supporting the expanding segments (428).

    Abstract: A self-supporting tyre (1) has reinforcing structures at the beads (4) defining rest surfaces (4a) for a corresponding rim (1a) which have a profile converging towards the tyre rotation axis away from the equatorial plane (X-X) of the tyre itself. The carcass plies (3a, 3b) are each made by sequential deposition of strip-like sections circumferentially distributed on a toroidal support (11). Elastic-support inserts (16, 21) are interposed between the side portions (13a, 14a) of axially internal sections (13), axial intermediate sections (15). In this manner around at least one of said support inserts opening degree of which can be modulated depending on requirements, by modifying the land/empty space ratio determined by the distance existing between the side portions (13a, 14a, 15a) of the strip-like sections (13, 14, 15) covering each of the axially opposite sides of the support insert itself.

    Abstract: A self-supporting tire for vehicle wheels includes a carcass structure having at least one carcass ply, a belt structure, a tread band, at least one pair of sidewalls, and at least one pair of resilient stiffening inserts incorporated into the carcass structure. The at least one carcass ply includes axially-inner strip lengths and axially-outer strip lengths, and may also include axially-intermediate strip lengths. Each of the strip lengths extend in a U-shaped configuration around a cross-section outline of the carcass structure to define two side portions spaced apart from each other in an axial direction and a crown portion extending at a radially-outer position between the side portions. The resilient stiffening inserts are axially interposed between the side portions of the axially-inner strip lengths and the side portions of the axially-outer strip lengths.

    Abstract: Tire components are assembled on a tire building drum by laying a first liner on a surface of the drum, positioning first sidewall inserts below the cylindrical surface of the drum and around the drum at insert locations spaced from each end of the drum, laying a first carcass ply around the drum, positioning second inserts over the first ply at the insert locations, laying a second carcass over the first ply and the second inserts, positioning beads at each end of the drum, expanding the drum to increase the diameter of the cylindrical surface of the drum and provide shoulders at each end of the drum, turning edges of the first ply and the second ply over each of the beads, positioning a belt and tread assembly around the second ply, and contracting the drum for removal of the assembled tire components from the drum. The inserts are positioned in grooves extending radially inwardly in the outer surface of the building drum. The grooves enable thick inserts to be built into the tire sidewall while still maintaining a generally flat outer surface of the tire while on the building drum, thereby decreasing the possibility of air trapped between components of the uncured tire.
