A cord comprising at least a first pair and a second pair of wires (2a, 2b) of different diameter randomly disposed in transverse cross section thereof, is obtained by arranging in a nacelle (7) of a double-twisting laying machine, a twister (16) operating upstream of a preformer (15). The twister (16), rotating in a direction opposite to that of the impeller (5) and at a speed which is twice that of the impeller, neutralizes the internal torsional stresses induced in the wires (2a, 2b) by effect of the double twisting carried out upon the action of the impeller itself. Thus, a better control of the preforming operation executed on the wires (2a, 2b) disposed parallel in respectively coplanar axes is enabled. The obtained cord (1), within each laying pitch and only under a traction condition involving a load not exceeding 5 kg, has at least one right cross section in which at least one wire (2a, 2b) is spaced apart from at least one of the adjacent wires so as to facilitate the rubberizing step, by enabling access of the blend to the cross section and penetration thereof along the cord axis. The cord is preferably used as a reinforcing element for the belt structure. |

A method is provided for making metal cords to be used as reinforcing elements in elastomeric structures which comprises arranging the wires in groups with the wires of each group being arranged coplanar and side by side, permanently deforming the wires by bending to wind the wires in a regular and uniform helical arrangement, with the helexes of all the wires having the same geometrical characteristics. The resulting cord is free from residual tensions which might loosen the mutual strand. |
