ABSTRACT:
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.
