Embodiment Construction

[0022] exist figure 1 with figure 2 , schematically shows a first exemplary embodiment of an apparatus for melt spinning, discharging, drawing, relaxing and winding a plurality of synthetic filaments according to the present invention in various views. figure 1 The exemplary embodiment is shown in side view, at figure 2 , the front view shows the exemplary embodiment. The following description applies to both figures without specific explanation for each figure.

[0023] This exemplary embodiment has a spinning unit 1, a godet system 15 and a winding unit 28 which are arranged one above the other in order to produce a Or a substantially vertically oriented thread path is obtained with a plurality of synthetic threads.

[0024] The spinning unit 1 has a spinning beam 8 which carries a plurality of spinning nozzles 2 on its underside. In this exemplary embodiment, two spinnerets 2 are held on the spin beam, each of which is designed as a double nozzle 7.1 and 7.2. Each o...

Abstract

The invention relates to a device for melt-spinning, drawing off, stretching, relaxing, and winding a synthetic thread. The device has a spinning apparatus, a galette system, and a winding apparatus, wherein the galette system contains at least one driven drawing-off galette, a plurality of driven stretching galettes, and a plurality of driven relaxing galettes, which are arranged one after the other with respect to a thread course and which guide the thread on the curved guiding surfaces thereof at a thread wrap of at most 270°, wherein the curved guiding surfaces of the galettes are heated or unheated. According to the invention, in order to minimize the control complexity of the plurality of galettes of the galette system, at least one of the relaxing galettes has a heated large curved surface, which has a larger diameter than the upstream heated curved guiding surface of the upstream stretching galettes and / or relaxing galettes.

Description

technical field [0001] The present invention relates to a device for melt spinning, ejecting, drawing, relaxing and winding synthetic yarns. Background technique [0002] In the production of synthetic yarns by the melt spinning process, it is generally known to determine the physical properties of the yarn extruded from the polymer melt by discharging the yarn from a spinneret, by drawing the yarn, and by relaxing the yarn. These process steps are substantially carried out by means of a godet system which is formed from a plurality of godets with rotating guide hoods. The guide hoods of the godet rollers of the godet roller system are specified to be heated or not heated in order to obtain a defined thread treatment for discharge, drafting and relaxation. Furthermore, two godet systems are known from the prior art which differ substantially in the guidance of the thread on the guide hood of the godet. [0003] For example, WO 2002 / 090633 discloses a device for melt spinni...
