    摘要： Within the tyre manufacture, a belt structure (2) is made by means of strip-like segments or elements (15) each comprising parallel cords embedded in an elastomeric layer, sequentially laid along the circumferential extension of a toroidal support (3), in such a manner that: -each strip-like element (15) is laid in a laying trajectory (T) defining, at each point, a laying angle (α); - at each point of the laying trajectory (T) a laying gap (Δg) is formed between adjacent strip-like elements (5); - said laying trajectory (T) is formed starting from preselected laying angles on the shoulder (αsp) and on the crown (αc) of the tyre; - the laying gap (Δg) between adjacent strip-like elements (5) varies along at least one section of said laying trajectory (T) between crown and shoulder so as to cause variation of said laying angle (α) and obtain said preselected angles on the shoulder (a,,,, ) and on the crown (αe).

    摘要： In tyre manufacture, a belt structure (2) is made by means of strip-like segments (5) each comprising parallel cords incorporated into an elastomeric layer, which strip-like segments (5) are sequentially laid down in mutual circumferential side by side relationship on a toroidal support (3). The apparatus for manufacturing such a reinforcing structure for vehicle tyres comprises: - a laying unit (100) comprising at least one laying assembly (9, 91) designed to apply each of said strip- like elements (5) onto a toroidal support (3), according to a predetermined laying angle (α) relative to a circumferential extension direction of the toroidal support itself; -said laying assembly (9, 9') comprising at least a first presser element (14), movable in contrast relationship against the outer surface (3a) of the toroidal support (3); said first presser element (14) comprises at least one tapered end (31) adapted to perform said contrast relationship and forming a tilted side (32) according to a tilt angle (β) correspondent to said predetermined laying angle (α) of the strip-like elements.

    摘要： In a process of manufacturing pneumatic tyres, a carcass sleeve (14) is made which comprises at least one carcass ply (3) provided with axially opposite flaps (3a) turned up around annular anchoring structures (5), so as to form respective loops (16). An outer sleeve (35) is positioned around the carcass sleeve (14) and the latter is radially expanded in order to cause application of same against a radially internal surface of the outer sleeve (35). After each of the end flaps (3a) has been turned up and before radial expansion, only a portion (25) belonging to each of the loops (16) and extending substantially parallel to the respective annular anchoring structure (5) is submitted to a step of carrying out heating under pressure, to make each loop (16) integral with the annular anchoring structure (5) and prevent the turned- up ply/plies from even partly slipping off, during the subsequent radial-expansion step of the carcass sleeve (14) and vulcanisation step of the tyre (2).

    摘要： Belt structure (2) for two-wheeled vehicle made by means of strip-like segments or elements (15) each comprising parallel cords embedded in an elastomeric layer, sequentially laid along the circumferential extension of a toroidal support (3) so as to form a reinforcing layer (2) having a continuous circumferential extension around a geometric rotation axis (X-X) of said toroidal support (3), wherein - each strip-like element (15) is laid in a laying trajectory (T) defining, at each point, a laying angle (α); - at each point of the laying trajectory (T) a laying gap (Δg) is formed between adjacent strip-like elements (5); - said laying trajectory (T) is formed starting from preselected laying angles on the shoulder (αsp) and on the crown (αc) of the tyre; - the laying gap (Δg) between adjacent strip-like elements (5) varies along at least one length of said laying trajectory (T) between crown and shoulder so as to cause variation of said laying angle (α) and obtain said preselected angles on the shoulder (αsp) and on the crown (αc).
