Embodiment Construction

[0034] figure 1 and figure 2 A first embodiment of the device according to the invention is shown in several views. exist figure 1 is shown in cross-sectional view in figure 2 Shown in top view. Therefore, if one of the figures in question is not explicitly indicated, the following description applies to both figures.

[0035]This exemplary embodiment has two godet pairs with godets 1.1 and 1.2 and godets 1.3 and 1.4 arranged below them. The godet 1.1 has a godet housing 2.1 which is supported in a cantilevered manner on a godet support 4.1 via a godet shaft 11.1 which is fixed to rotate against the godet The wire sheath 2.1 is coupled and driven via a godet drive 14.1.

[0036] A second godet 1.2 is arranged on the godet support 4.1 at a distance from the godet 1.1. The godet 1.2 has a godet housing 2.2, which is coupled in a rotationally fixed manner to the godet shaft 11.2. The godet shaft 11.2 is mounted with an overhanging end in a freely rotatable manner in the...

Abstract

The invention relates to a device for removing and stretching multifilament threads in a melt spinning process, wherein at least two galettes, arranged at a distance from each other, having rotary guide casings and a heating means arranged between the galettes, are provided. The threads are guided by one or more loops at the guide casings of the galettes and heated by the heating means in the thread pieces thereof tensioned between the galettes. In order to achieve energy transmission that is largely unaffected by the environment, the heating means is formed, according to the invention, by a plurality of infrared radiation bodies arranged next to each other, which extend substantially parallel to the guide casings of the galettes and which are arranged between the guide casings of the galettes in the free space delimited by the tensioned thread pieces.

Description

technical field [0001] The invention relates to a device according to the preamble of claim 1 for drawing and stretching multifilament filaments during melt spinning. Background technique [0002] When producing multifilament filaments in a melt spinning process, it is known that the freshly spun multifilament filaments are withdrawn from the spinning unit and drawn more or less depending on the filament type and possibly additionally processing so that the multifilament filaments can be wound into a bobbin at the end of the processing. For drawing and stretching the multifilament filaments, godet rollers are usually used which have a driven godet housing, on the periphery of which the filaments are guided in a partial wrap. Depending on the desired draw ratio or the draw force required by the draw ratio, the godet is wound by the filament one or more times. In particular, the drawing process in multifilament filaments is assisted here by tempering the filaments. In order...
