Abstract (en)

[origin: WO2007115703A1] A method and an apparatus for pulling off and drawing a multifilament thread during melt-spinning are described. Here, the thread is guided by guide casings of two driven galettes with a partial wraparound and is clamped between the galettes with a thread piece. In order for it to be possible for high stretching forces to be produced at the galettes with a single wraparound, the thread piece between the galettes is formed according to the invention by a thread loop, wherein the thread is guided at the loop end via a rotatably mounted deflection roller which is held at a spacing from the guide casings of the galettes.
