  • Patent number: 7241123
    Abstract: An apparatus for producing and winding synthetic multifilament yarns, which has a spin unit 1 for melt spinning the yarns, at least one treatment unit 7 for treating the yarns, and a takeup unit 16 with a plurality of winding positions for winding the yarns. The winding positions 17.1-17.3 are distributed along a horizontal axis of the takeup unit 16, with a driven guide roll 12 and a yarn guide 15.1-15.3 for each winding position being arranged upstream thereof for advancing the yarn. To prevent different yarn deflections despite a different spacing between yarns while treating and while winding the yarns, the invention provides for orienting the guide roll 12 with its roll axis in the vertical direction to guide the yarns, and for arranging it laterally adjacent the yarn guides 15.1-15.3 such that the yarns can be advanced substantially in parallel relationship between the guide roll 12 and the yarn guides 15.1-15.3.
