Thread-guiding device for collecting spun yarns on bobbins, particularly for open-end spinning frames, constituted by a common thread-guiding rod which carries the thread-guides for the spinning stations, said rod being operated in alternate movement in front of the bobbins being formed by a linear electric motor driven by the control unit of the spinning frame in its alternate backward and forward movement as regards instantaneous speed, amplitude of excursion, axial coordinates of the ends of the travel of the thread-guiding rod.
