<p>Metal cord, for reinforcing articles of an elastomeric material, such as tires, conveyor belts and so on of the single strand type, in particular made up of a plurality of 3, 4 or 5 wires, wherein the said wires are twisted together loosely, so as to result as being spaced apart from each other but in such a way that the ratio between the diameter of the circumference circumscribing the swollen cord and the diameter of the circumference circumscribing the corresponding compact cord, is comprised between 1.06 and 1.20. A thus realized cord consents for an optimum penetration of the elastomeric filler material but at the same time a tensile behavior, and in particular an elongation in the field of low values of loads applied, which does not differ in any appreciable way from that of the corresponding compact cord.</p> |
