Patent ID: 7197809

Claim:
A method for fabricating a stranded cable particularly for mechanical motion transmission comprising: winding strands or wires that form the stranded cable in a helical arrangement around a common longitudinal axis, flattening and smoothing the exterior profile of each strand of the stranded cable by hammering the stranded cable in hammering directions perpendicular to the longitudinal axis at hammering sectors having the shape of sectors of a circumference until the average diameter of the stranded cable after hammering is reduced to a diameter of about 80% to about 99.9% of the average diameter of the stranded cable before hammering, wrapping the stranded cable in a jacket, wherein wrapping the stranded cable comprises passing the stranded cable through an extruder supplied with plastic or PTFE, said stranded cable being wrapped in said jacket by extrusion of plastic or PTFE around the stranded cable in the extruder, wherein a chamber is formed between the jacket surrounding two adjacent wires and the inner surface of a sheath, and wherein the chamber has a helical arrangement along the stranded cable.
