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.
