<p>Thread-guiding device for collecting spun yarns on bobbins, particularly for open-end spinning frames, constituted by a common thread-guiding rod (22) which carries the thread-guides (21) for the spinning units (2), driven in alternate movement in front of the bobbins being formed by the motion of a driving means (41,55,65) controlled in turn by a motor (47,53,63) 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. <IMAGE></p> |
