Abstract
A method of manufacturing a high transverse-curvature motor-bike tire includes the steps of providing a carcass structure on a main assembly drum, providing at least one strip made of an elastomeric material incorporating a plurality of reinforcing cords on a comb-like drum, radially expanding radially-mobile sectors associated with the drum, circumferentially winding at least one inextensible cord on the at least one strip to form circumferential coils and to define a belt structure, circumferentially associating a tread around the belt structure, and associating the belt structure, together with the tread, around the carcass structure. The at least one cord is wound on the at least one strip at a substantially-null angle with respect to the equatorial plane of the drum according to a winding direction adapted to compression-stress, at least during initial winding, elastomeric material portions interposed between consecutive reinforcing cords incorporated in the at least one strip.
