摘要： A carcass ply (3) is formed by laying on a toroidal support (11) a first and a second series of strip-like segments (13, 14) cut to measure from a continuous strip-like element (2a) and each comprising longitudinal filiform element (15) incorporated in a layer of elastomeric material (18). The segments (13) of the first series are laid sequentially at a certain circumferential distance from each other, to form lateral portions (19) on whose terminal edges (19a) are applied primary portions (4a) of respective reinforcing structures (4) to the beads comprising each a frist and a second annular insert (23, 24). The segments of the second series (14) are interposed each in the space defined between two segments of the first series (13), with respective terminal edges (20a) superposed to the primary portions (4a) of the annular structures (4). A third annular insert (26) is applied against the terminal edges of the segments (14) belonging to the second series to enclose said terminal portions against the second insert (24). An auxiliary filling body (27), extending radially away from said third annular insert, is also formed.

摘要： A tyre for vehicle wheels has a pair of beads (5) each having a frusto-conical rest surface (5a) and showing a cross-section profile converging towards the rotation axis of the tyre (1) away from an equatorial plane (X-X) of same. Each bead (5) incorporates an annular anchoring structure (4) comprising an anchoring portion (16) of a flattened profile extending in parallel to the rest surface (5a), and a stiffening portion (12) extending in a radial direction. Associated with the carcass structure (2) is a circumferential centring ridge (20) radially jutting out within the tyre (1) at a crown portion of the latter. Also described is a rim (23) provided with engagement seats (24) the shape of which matches that of the beads (5) and with a guide race (25) conforming in shape to the centring ridge (20).
