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.
