Abstract
A process for manufacturing a metal cord includes the steps of permanently deforming at least one wire using a substantially sinusoidal deformation lying in a plane and stranding the at least one wire together with one or more other wires by helicoidally double twisting the wires around a longitudinal axis of the metal cord. The metal cord may include at least two wires each with diameter greater than or equal to 0.10 mm and less than or equal to 0.50 mm. An associated metal cord includes at least two wires. One or more of the at least two wires is permanently deformed using a substantially sinusoidal deformation lying in a plane. The at least two wires are stranded together by helicoidally double twisting the at least two wires around a longitudinal axis of the metal cord.
