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.
