摘要： A first carcass ply (3) is formed by depositing onto a toroidal support (11), strip-like lengths (13) cut to size from a continuous strip-like element and each comprising longitudinal thread-like elements (14) incorporated into a layer of elastomer material (17). The strip-like lengths are laid down sequentially in mutual circumferential side by side relationship, to form side portions (25) partly superposed on each other and crown portions (24) in mutual circumferential side by side relationship. Associated with the carcass ply (3) are annular structures (4) comprising a first and a second circumferentially inextensible annular inserts (27, 28) and an elastomer filling (29) interposed therebetween. A second carcass ply (31) is made in superposed position to the first carcass ply (3) and the annular structures (4). A belt structure (5), a tread band (8) and sidewalls (9) are combined with the carcass structure (2) thus formed, to define a tire (1) to be vulcanized.

摘要： In forming a green tire by arranging a plurality of carcass cords on a support member and disposing bead cores, the carcass cords are precisely and accurately disposed at predetermined positions. A plurality of carcass cords (C) are arranged over the entire circumference of a core (21), and the ends thereof are attached to the end holding means (30) so that the ends are held at positions distant from each other axially outward of the core (21) in a stretched state between the core (21) and themselves. Bead cores (60) are moved from the outside of the carcass cords (C) toward bead molding portions (24) of the core (21), are brought into contact with the carcass cords (C) held at the ends, and are pressed against the core (21). This pressing force presses the carcass cords (C) in the traveling direction of the bead cores (60), displaces them toward the core (21) in a stretched state, sequentially disposes the carcass cords (C) on the side surfaces of the core (21), and disposes the bead cores (60) on the bead molding portions (24) with the carcass cords (C) therebetween.

摘要： A method of manufacturing a carcass structure for vehicle tires includes the steps of making at least one carcass ply by deposition of elongated sections circumferentially distributed on a toroidal support and applying annular reinforcing structures to a region close to inner circumferential edges of the at least one carcass ply. Each of the elongated sections extends in a U-shaped configuration around a cross-sectional outline of the toroidal support to define two side portions mutually spaced apart in an axial direction and one crown portion extending at a radially outer position between the side portions. Each of the elongated sections is laid down substantially in a plane parallelly offset relative to a meridian plane of the toroidal support. A related carcass structure and tire are also disclosed.

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.
