Abstract:
A machine for manufacturing metal cords, particularly metal cords for reinforcing composite elastomeric products, comprising:a supporting structure; a rotor, having a predefined rotation axis, engaged with respect to the supporting structure; a cradle fastened to the supporting structure according to an oscillation axis which coincides with the rotation axis of the rotor; feeding devices operatively fitted on the cradle to feed a plurality of elementary wires from respective feeding spools, wherein the elementary wires are driven onto the rotor according to a stranding path, wherein the stranding path has end sections coinciding with the rotation axis of the rotor, and wherein the stranding path has a central section distanced from the rotation axis of the rotor; and at least one preforming device operatively engaged with the cradle and operating on at least one of the elementary wires in a section upstream with respect to a first end section of the stranding path, wherein the at least one preforming device provides the at least one of the elementary wires a substantially sinusoidal deformation lying in a plane.
