Abstract: Variable-diameter tire-building drum intended for the manufacture of a green tire having a generally cylindrical receiving surface formed of radially mobile sectors and bearing elements the radially external part of which constitutes the receiving surface, the receiving surface comprising at least one circular groove containing an elastic circumferential sleeve which is held radially away from the bottom of the groove by pushers able to move radially with respect to the mobile sectors so as to align the radially external surface of the sleeve with the receiving surface when the drum is brought to a first laying diameter, and which is pressed against the bottom of the groove under the effect of circumferential elastic tensions when the drum is placed at a laying diameter greater than the said first laying diameter. Disengageable locks are able to keep the pushers in the position in which the radially external surface of the sleeve is aligned with the receiving surface regardless of the diameter to which the said receiving surface is brought.

Abstract: [Problem ] It is a manufacturing method for a pneumatic tire 1 having a green tire formation process for applying an unvulcanized carcass ply 6A to the outer surface of a rigid core 20. The green tire formation process includes a process for continuously forming a plurality of strip-shaped sheet-like first ply pieces 13 by cutting a long ribbon-shaped ply 12 along a ply-width direction sequentially from the leading end, a ply piece forming process for continuously forming a plurality of strip-shaped sheet-like second ply pieces 14, and a carcass forming process for forming the unvulcanized carcass ply 6A by the use of the first and second ply pieces 13, 14. The second ply pieces 14 are not overlapped with the first ply pieces 13 at the tire equator Co, but directly overlapped with the first ply pieces 13 in the radially inner end portions 14i of the second ply pieces 14.

Abstract: A method of assembling a tire having one or more reinforcements or supporting inserts in the sidewalls is provided. The reinforcements are positioned onto one or more air impermeable layers. One or more reinforcing plies are positioned over the reinforcing supports and suspended therebetween. A gas pressure is used to expand the one or more air impermeable layers away from the forming drum and against a reinforcing ply. As such, the creases or wrinkles in the one or more reinforcing plies can be avoided along with other non-uniformities such as deradialization and/or an uneven overlap where the ends of a ply are joined.

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: 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 run flat pneumatic tire has a thin annular band embedded in the crown portion of the tire. The band is formed of a composite material such as tows of fiberglass and/or graphite material impregnated with a resin. The resin coated tows are wound about a mandrel having at least one concave recess to provide the band with an anticlastic shape with an arcuate cross section and a concave surface facing radially outwardly.

Abstract: The run-flat tire (10) of this invention includes spaced apart bead areas (30) having a unique design to include first (34) and second (36) bead fillers adjacent a bead core (32). The second bead filler (36) is bounded by the first bead filler (34) and bead core (32). The method for manufacturing the tire to eliminate voids at the bead core (32) of the cured tire is also provided. The bead fillers are made to be resilient so that the tire can be easily mounted on a rim, particularly improving the ability to mount a run-flat tire (10) on a rim (80). The bead core (32) and fillers (34, 36) are designed for helping to sustain the run-flat tire (10) on the rim (80) with a loss of inflation pressure and to improve the running performance of the tire.

Abstract: A tire includes a central region configured to be mounted to a wheel and a crown region including a circumferential tread and a shear element disposed below the circumferential tread. The shear element includes an upper reinforcement layer, a lower reinforcement layer, and an elastic region disposed between the upper reinforcement layer and the lower reinforcement layer. A radial distance between the upper reinforcement layer and the lower reinforcement layer varies along an axial width of the tire. The tire also includes an intermediate region extending from the central region to the crown region.
