ABSTRACT:
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 units, driven in alternate movement in front of the bobbins being formed by the motion of a driving means controlled in turn by a motor capable of alternate rotation and controlled by the control unit of the spinning frame in its alternate clockwise/counterclockwise movement as regards instantaneous speed, amplitude of angular excursion, angular coordinates of the ends of its travel.
