摘要:
A method for producing a vehicle tire belt structure includes forming at least one belt strip including at least one circumferential edge with a profile extending along a broken line. A vehicle tire includes a carcass structure, tread band, and belt structure. At least one carcass ply of the carcass structure includes reinforcing cords oriented substantially along radial planes of the tire. The belt structure includes at least one pair of radially superimposed belt strips including a plurality of reinforcing cords parallel to each other. The reinforcing cords of a first belt strip cross those of a radially adjacent belt strip. The reinforcing cords of the first and radially adjacent belt strips are obliquely oriented in opposite directions with respect to an equatorial plane of the tyre. At least one of the belt strips includes at least one circumferential edge with a profile extending along a broken line.
摘要:
A pneumatic tyre for a vehicle wheel includes a toroidal carcass, a tread band, a belt structure, and at least one reinforcing layer associated with the carcass. The carcass includes at least one carcass ply having a substantially continuous right-section profile. The carcass has a central crown portion and two axially opposite sidewalls. Each sidewall terminates with a bead for mounting the tyre on a corresponding rim. Each bead includes at least one reinforcing core. The tread band is disposed crownwise, coaxially extending around the carcass, and includes a raised pattern for rolling contact with the ground. The belt structure is coaxially interposed between the carcass and the tread band. The tyre has a size ratio f/H less than 0.2:1. The at least one reinforcing layer is disposed radially external to a point of maximum axial width of the carcass and axially external to the belt structure.

A method for manufacturing a tyre includes forming a carcass structure, forming a tread band, placing the tyre in a curing mould, and moulding and curing the tyre. The carcass structure includes a crown portion defined between two axially opposed sidewalls that extend radially toward an axis of rotation of the tyre and terminate in a circumferential portion comprising an annular reinforcing structure for mounting the tyre on a rim. The tread band extends circumferentially around the carcass structure and includes a moulded 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.
