ABSTRACT OF THE DISCLOSURE In an optical fiber cabling line where a ring having helical grooves is drawn at a constant translational speed by a main motor,there is provided a system for slaving a rotational speed of an optical fiber feeding and dispensing device driven by motor means to a number of ring groove pitches per second in order to compensate for groove pitch fluctuations resulting from the ring production process. The system comprises roller and cam means coupled to the ring and to the feeding and dispensing device for detecting a difference between the rotational speed and the number of pitches per second thereby converting the speed difference into a voltage variation. The motor means comprises a differential coupled to a gearbox connected to the main motor, and a corrector motor linked to the detecting means so as to drive rotationally the feeding and dispensing means at a rotational speed proportional to a rotstional speed set by the gearbox and continuously corrected by the detected speed difference.
