TYRE FOR TWO -WHEELED VEHICLE AND PROCESS FOR MANUFACTURING THE SAME

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 (a); - at each point of the laying trajectory (T) a laying gap (?g) is formed between adjacent strip-like elements (5); - said laying trajectory (T) is formed starting from preselected laying angles on the shoulder (asp) and on the crown (ac) of the tyre; - the laying gap (?g) 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 (a) and obtain said preselected angles on the shoulder (asp) and on the crown (ac).
