    Abstract: A tyre for vehicle wheels comprises a support structure and a tread band arranged in a radially outer position with respect to the support structure. The support structure comprises a plurality of hybrid reinforcing cords (10). Each of the hybrid reinforcing cords (10) has at least two strands (20) twisted together with a predetermined twisting pitch. Each of said at least two strands (20) comprises at least one monofilament textile wire (21) and at least one multifilament textile yarn (22) comprising a plurality of textile filaments (22a). In any cross section of the hybrid reinforcing cord (10), said at least one monofilament textile wire (21) is at least partially embedded in the filaments (22a) of said at least one multifilament textile yarn (22).

    Abstract: A tyre (100) for vehicle wheels comprises a carcass structure (101), a crossed belt structure (106) arranged in a radially outer position with respect to the carcass structure (101), at least one zero degrees reinforcing layer (106c) arranged in a radially outer position with respect to the crossed belt structure (106) and a tread band (10) arranged in radially outer position with respect to the zero degrees reinforcing layer (106c). The crossed belt structure comprises a first belt layer (106a) and at least one second belt layer (106b) arranged in a radially outer position with respect to the first belt layer (106a). At least one of the belt layers (106a, 106b) comprises a plurality of hybrid reinforcing cords (10) each having a core (11) made of a high modulus textile material and extending along a predetermined longitudinal direction (A) and a plurality of metallic wires (12) substantially parallel to one another and helically wound around the core (11) with a predetermined winding pitch (P). The metallic wires (12) are arranged around the core (11) so that, in any cross section of the hybrid reinforcing cord (10), they are located at only one angular portion of an ideal circumference (C) that circumscribes the core (11). The zero degrees reinforcing layer (106c) includes a plurality of non-hybrid reinforcing cords (10c).

    Abstract: A tyre for motorcycles comprises a carcass structure, a belt structure arranged in a radially outer position with respect to the carcass structure and a tread band arranged in a: radially outer position with respect to the belt structure. The belt structure is. of the zero degree type and comprises at least one reinforcing cord comprising a core (12) made of non metal material.- and a: plurality of metal wires (13) substantially parallel to one another and helically wound around said core (12). with a predetermined winding pitch. The metal wires (13) are in such a number as to not completely surround the core (12).- In particular, the metal wires (13) are arranged around the core (12) so that, in any cross-section of the reinforcing cord (11), they are located at just an angular portion of an ideal circumference that circumscribes the core (12).

    Abstract: The process for manufacturing a steel wire comprises: providing a steel wire; austenitizing said steel wire; patenting said steel wire; drawing said steel wire. The patenting of said steel wire comprises: slow cooling said steel wire to a first predetermined temperature; quick cooling the steel wire to a second predetermined temperature; keeping said steel wire at said second predetermined temperature. During the slow cooling, the steel wire substantially keeps its austenite structure unaltered; with the subsequent quick cooling, the steel wire is taken to the best conditions in order to start the phase change in which the austenite structure is transformed into a pearlite structure.

    Abstract: A tyre for vehicle wheels comprises a support structure and a tread band arranged in a radially outer position with respect to the support structure. The support structure comprises a plurality of hybrid reinforcing cords (10) each having a plurality of monofilament textile wires (20) twisted to at least one multifilament textile yarn (30). In any cross section of the hybrid reinforcing cord (10), at least one portion of at least one monofilament textile wire (20) of said plurality of monofilament textile wires (20) defines a first radially outer surface portion of the hybrid reinforcing cord (10) and at least one portion of said at least one multifilament textile yarn (30) defines a second radially outer surface portion of the hybrid reinforcing cord (10).
