摘要： A method for manufacturing a tyre for vehicle wheels, includes a carcass structure having at least one carcass ply associated with axially opposite annular anchoring structures. The method includes the steps of manufacturing at least one pair of annular anchoring structures of the carcass structure and associating the pair of annular anchoring structures with the at least one carcass ply at axially opposite end flaps of the carcass ply. The step of manufacturing each annular anchoring structure includes the steps of manufacturing a bead core and coating the bead core with a reinforcement tape through an apparatus. The step of coating the bead core includes the steps of winding the reinforcement tape onto the bead core moving a tape deposition member with respect to the bead core. The step of manufacturing the annular anchoring structure further includes a step of loading the reinforcement tape onto the tape deposition member. This last step is carried out simultaneously with at least part of the step of winding the reinforcement tape onto the bead core.

摘要： During manufacture of a tyre for motor vehicles, one or more structural elements of elastomeric material, such as a tread band provided with a respective under-layer, are manufactured by laying a continuous elongated element on the carcass structure or other forming support, which elongated element is longitudinally divided into a first and second mutually-coupled portions that are obtained through extrusion of two different elastomeric materials coming from respective extruders leading to a common extrusion die. Laying of the coils takes place in such a manner that the first and second materials form a first layer and a second layer overlapping the first layer, respectively.

摘要： A method for manufacturing a tire includes forming a carcass structure, forming a tread band, placing the tire in a curing mold, and molding and curing the tire. The carcass structure includes a crown portion defined between two axially opposed sidewalls that extend radially toward an axis of rotation of the tire and terminate in a circumferential portion comprising an annular reinforcing structure for mounting the tire on a rim. The tread band extends circumferentially around the carcass structure and includes a molded relief pattern. Forming the tread band includes producing a strip of elastomeric material and winding it onto the crown portion. The strip includes an elongated right cross-section that is asymmetrical in a transverse direction. The strip is wound in a plurality of axially consecutive turns until the tread band is formed. At least one turn is at least partly overlapped onto a previously deposited, axially consecutive turn.

摘要： One or more components of elastomer material in a tyre are formed by dispensing elastomer material through a nozzle of an extruder to form a continuous elongated element of flattened section that is laid in the form of coils disposed close to each other on a laying surface carried by a support element, while said support element is driven in rotation and suitably moved adjacent to a die of the nozzle. The nozzle is drivable in rotation by an actuator so as to modify orientation of the nozzle itself during formation of the tyre component.

摘要： A tyre for a vehicle wheel includes a carcass structure, a pair of annular reinforcing structures, a tread band, and a pair of sidewalls. The carcass structure includes at least one carcass ply including two lateral portions and a crown portion. The at least one carcass ply comprises elongated elements arranged in a substantially U-shaped configuration around a profile of a cross-section of the tyre. A density of the elongated elements is greater in the lateral portions than in the crown portion. The density of the elongated elements increases continuously and regularly in end zones of the lateral portions in directions away from the crown portion. A shape of a cross-section of each elongated element is constant. A method for forming the tyre includes preparing a plurality of strip elements, constricting end zones of each strip element, and laying the strip elements with constricted end zones on a toroidal support.

摘要： A semi-finished product of elastomeric material includes a strip suitable for manufacturing an inner gas-impermeable coating layer of a pneumatic tyre. A right cross-section of the strip includes a profile that tapers axially outwards on at least one edge of the strip. A method for manufacturing a tyre for a vehicle wheel includes forming a layer of liner on a rigid support by laying at least one strip of elastomeric material on the rigid support in axially consecutive turns, laying other semi-finished products suitable for forming other components of the tyre in a radially outer position with respect to the layer of liner, and vulcanizing the layer of liner and other semi-finished products. The at least one strip includes a right cross section including the tapered profile. A tapered portion of a first turn is axially overlapped on an axially adjacent turn that was previously laid on the rigid support.
