Abstract: An apparatus for building tyres for vehicle wheels are described. A substantially cylindrical carcass sleeve, having at least one carcass ply, includes consecutively adjacent strip-like elements laid one after the other around the circumferential extension of a substantially cylindrical deposition surface. Circumferentially consecutive strip-like elements laid one after the other form overlap zones along respective longitudinal edges superimposed on each other. Each overlap zone has, along a longitudinal extension thereof, terminal sections that are laterally opposite with respect to an intermediate section. The intermediate section of each overlap zone has greater width than the width of the terminal sections.

Abstract: A tire having reduced mass and low rolling resistance and a method of manufacture thereof achieves reduced weight by using thin layers of thermoplastic polyurethanes (“TPU's”) to heat seal the carcass, breaker, and tread layers of the tire to each other, rather than embedding the layers in conventional, relatively thicker and heavier layers of sulfur cured vulcanized carbon filled elastomers. Creep and “spring-back” of the thermoplastic polyurethanes during cure is avoided by maintaining the adhered layers under pressure until the assembly cools below its glass transition temperature. In embodiments, the heat sealing can be performed on the forming drum, and in some embodiments cool rollers are applied to the heat-sealed carcass so as to accelerate the cooling to below the glass transition temperature.

Abstract: A method of forming a layer of tire ply is disclosed. A first strip of ply is provided having a plurality of evenly spaced reinforcement cords, having a spacing S, and having a lateral end, wherein the last cord is spaced apart from strip end a distance X, wherein X is not equal to S. A second strip of ply is provided having a plurality of evenly spaced reinforcement cords, having a spacing S, and having a lateral end, wherein the last cord is spaced apart from strip end a distance Y, wherein Y is not equal to S. The lateral ends of the first and second strip are joined together in a lap joint. The first and second lateral ends are overlapped so that the spacing X preferrably does not overlap, but may partially overlap with the spacing Y.

Abstract: A tire that may improve pressure resistance and cut resistance. The tire is provided with a tire carcass member fabricated of resin and a reinforcing layer. The tire carcass member includes a bead portion covering a bead core, a side portion extending to a tire radius direction outer side from the bead portion, and a crown portion extending to a tire width direction inner side from the side portion. The reinforcing layer is provided with a plurality of cords that are covered with resin or rubber, extends from the bead portion of the tire carcass member toward the side portion, and covers at least an outer periphery face of the side portion.

Abstract: In order to enable the suppression of the occurrence of poor appearance, a pneumatic tire (1) is provided with a carcass (6) configured from at least one carcass ply (6A). The carcass ply (6A) is formed by arranging, in the tire circumferential direction, rectangular sheet-shaped ply pieces (11) each having a radial direction length (L2) larger than a tire circumferential direction length (L1). In each of the ply pieces (11), carcass cords (12) are arranged parallel to each other in the longitudinal direction, and the ply piece (11) and a ply piece (11) adjacent thereto at least partially overlap with each other in the tire circumferential direction. Further, in each of the ply pieces (11), the distance (Pe) between the carcass cords (12) in at least one side edge portion (11e) in the circumferential direction of the ply piece (11) is larger than the distance (Pc) between the carcass cords (12) in the central portion (11c) of the ply piece (11).
