Zusammenfassung:Process according to which, during the fibre production, a thin continuous coating is deposited on the fibre (2), characterised in that a partial ablation of this coating is then carried out, in the form of a helix (15) of the same axis as the fibre, by using a laser beam (17) rotating in a plane at right angles to the said axis, during the forward travel of the fibre.
