  • Patent number: 6079655
    Abstract: The invention concerns an arrangement of inlet elements in a spin draw winding machine in which filament bundles (5, 6) guided parallel are deflected by a roll each and are taken off therefrom in which arrangement further rolls can be provided upstream from the transfer point of the filament bundles to a draw roll (4). In this arrangement, the difference between the wrapping angles of each filament bundle on the roll, or on the rolls respectively, is not to exceed 50% of the smaller wrapping angle for either of the filament bundles. Furthermore, it proves advantageous if the sum of all wrapping angles for each filament bundle is about 120 degrees or more.

  • Patent number: 5755086
    Abstract: A machine unit through which a thread is guided includes a drafting unit comprised of double godets, a texturing unit, a relax unit comprising double rollers, and a winding device. The drafting unit and the relax unit are arranged at an angle of less than 90.degree. to a reference plane, while the winding device is arranged at an angle (.delta.) of essentially 90.degree. to the reference plane. Furthermore, an operator's working position is provided, from which the aforementioned arrangement of the drafting unit and relax unit relative to the winding device is accessible.
