20100024949 | PROCESS FOR MANUFACTURING TYRES BY APPLICATION OF STRIPS HAVING DIFFERENT WIDTHS - A process for manufacturing a tyre includes: providing a first plurality of strip-like elements, each substantially having a first effective width; providing at least a second plurality of strip-like elements, each substantially having a second effective width; arranging the strip-like elements of the first plurality and of the second plurality on a support by approaching side edge portions thereof to one another, so as to form at least one reinforcing component of the tyre on the support; wherein the first effective width is different from the second effective width. | 02-04-2010 |
20110000598 | Tire with a Crown Comprising a Bielastic Reinforcing Element - A tire comprising a carcass reinforcement radially surmounted by a crown reinforcement comprising at least one layer of reinforcements, the tire furthermore comprising a bielastic reinforcing element extending circumferentially and comprising a bielastic fabric, the bielastic reinforcing element being, at least in part, radially adjacent to a portion of at least one reinforcing layer of the crown reinforcement, in the immediate proximity of an axial end of this reinforcing layer of the crown reinforcement. | 01-06-2011 |

20160059630 | TIRE PLY AND METHOD OF MANUFACTURE - 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 two cords are spaced apart 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 two cords are spaced apart 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 partially or completely overlaps with the spacing Y. | 03-03-2016 |
152560000 | Reinforcing cords of at least one carcass ply extend transversely across the tire from bead to bead (i.e., radial ply) | 4 |
20090236022 | PNEUMATIC TIRE - Provided is a pneumatic tire with a durability improved by preventing the oxidation degradation of a belt layer. The pneumatic tire includes: an air permeation preventive layer disposed in the inner surface of the tire; a belt layer buried in a tread part; and a cord layer formed by arranging a plurality of cords. The cord layer is disposed between the air permeation preventive layer and the belt layer, and extends to a bead part side further from a tire maximum width position. In addition, at least a part of the cord layer is located close to the outer surface of the tire, at a position closer to the bead part side than the tire maximum width position, so that the distance between the cords and the outer surface of the tire is not more than 2 mm. The following configuration may alternatively be possible. A cord layer is formed by arranging cords in parallel. The inner part of the cord layer is disposed between a carcass layer and the belt layer, while the outer part of the cord layer is disposed on the outer circumferential side of the belt layer, along the belt layer. Moreover, the cords of the cord layer are continuously extended, in a straddling manner, between the inner and outer parts. | 09-24-2009 |
20090301629 | PNEUMATIC TIRE - A heavy duty pneumatic tire that can realize a higher level of weight reduction while maintaining travelling durability comparable to an existing product and exhibiting sufficient carcass strength and rigidity is provided. An off-road pneumatic tire that can realize a higher level of weight reduction while maintaining travelling durability comparable to an existing product and exhibiting sufficient carcass strength and rigidity is also provided. | 12-10-2009 |
20100139834 | PNEUMATIC TIRE - A pneumatic tire | 06-10-2010 |
20110232819 | Tire for Heavy Vehicles Comprising at Least Two Additional Layers in the Beads - A tire with a radial carcass reinforcement comprising a crown reinforcement, itself radially capped by a tread strip, the said tread strip being connected to two beads via two sidewalls, the carcass reinforcement being anchored in each of the beads to form an anchorage region. The tire additionally comprises, in part of at least each of the anchorage regions, at least two layers formed by circumferential winding of a complex strip formed of two layers consisting of continuous reinforcing elements passing from one layer to the other, the said reinforcing elements being parallel within a layer and crossed from one layer to the other at angles with respect to the circumferential direction that are identical in terms of absolute value. | 09-29-2011 |
