Zusammenfassung:	A METHOD FOR AUTOMATIC CENTERING OF AN OPTICAL FIBER WITHIN A PRIMARY PROTECTIVE CLADDING AND A DEVICE EMPLOYED FOR CARRYING OUT SAID METHOD Highly accurate centering of an optical fiber within a primary cladding deposited by a coating device is carried out by automatic regulation during the fiberdrawing process in order to optimize the mechanical properties of the fiber. The position of the coating device is controlled in dependence on the position of the fiber with respect to an origin of coordinates (O) determined by optoelectronic means. The frusto-conical lower end of the coating die is maintained at-each instant by electronic and electromechanical means at the point (O') located at this level on the straight-line segment (OR) which joins the origin to the first point of contact of the fiber with the pulley used for guiding the fiber towards a storage drum.
