  • Thread-guiding device for open-end spinning frames
    Patent number: 6904745
    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 stations, said rod being operated in alternative 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, and axial coordinates of the ends of the travel of the thread-guiding rod.
    Type: Grant
    Filed: March 3, 2003
    Date of Patent: June 14, 2005
    Assignee: Savio Macchine Tessili S.p.A
    Inventors: Roberto Badiali, Vittorio Colussi, Franco Siega Vignut
  • Thread-guiding device for collecting spun yarns on bobbins particularly for open-end spinning frames
    Patent number: 6895736
    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.

  • Device for collecting yarns on conical reels with compensation of the fluctuations of the yarn take-up speed
    Patent number: 6682011
    Abstract: A device for collecting yarns on conical reels which compensates for the take-up pulsations of the thread winding onto the conical reel. The device comprises a fixed bar compensator at an adjustable oblique angle with respect to the winding line of the thread which varies the length of the free path of the traversing thread.
