ABSTRACT:
An apparatus for producing and winding synthetic multifilament yarns, which has a spin unit1for melt spinning the yarns, at least one treatment unit7for treating the yarns, and a takeup unit16with a plurality of winding positions for winding the yarns. The winding positions17.1-17.3are distributed along a horizontal axis of the takeup unit16, with a driven guide roll12and a yarn guide15.1-15.3for 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 roll12with its roll axis in the vertical direction to guide the yarns, and for arranging it laterally adjacent the yarn guides15.1-15.3such that the yarns can be advanced substantially in parallel relationship between the guide roll12and the yarn guides15.1-15.3.
