Device for guiding and texturing a plurality of synthetic threads

Abstract

The invention relates to a device for giding and texturing a plurality of synthetic threads. The device has at least one driven thread-guiding roller, multiple twist texturing nozzles and a cooling device. Herein, long threads on the periphery of the thread-guiding roller are guided with a guiding distance to the cooling device with a processing distance, wherein the guiding distance among the long threads on the thread-guiding rollers is smaller than the processing distance among the long threads on the cooling device. In order to lay the long threads from the guiding distance to the processing distance, the twist texturing nozzles are maintained between the thread-guiding rollers and the cooling device in a sectorial arrangement structure. In order to prevent unexpected deviation external long threads, the arrangement structure of the twist texturing nozzles are configured to be transverse with respect to the rotating axis of the thread-guiding rollers, and the long threads can be conveyed to the twist texturing nozzles through a linear long thread journey in different winding angles on the periphery of the thread-guiding rollers. therefore, the long threads can be conveyed to the twist texturing nozzles from the periphery of the thread-guiding rollers, parallel to each other and without any deviation.

Description

technical field [0001] The invention relates to an apparatus for guiding and deforming a plurality of synthetic filaments during melt-spinning according to the preamble of claim 1 . Background technique [0002] When producing texturized filaments in a melt-spinning process, the filaments are usually guided and processed together as a group of filaments after extrusion. As a rule, the filaments are guided together at a distance from one another over the circumference of the godet. Depending on the respective processing steps and the respective processing equipment, different filament spacings are required between the filaments. For example, the spin pitch (which defines the distance of the spinning nozzles from each other) is maintained when extruding the filaments. After extrusion, the filaments can be guided at a much narrower process distance from one another for guidance on the godet. Depending on the filament spacing requirements, the filaments either have to be laid...

AI Technical Summary

Problems solved by technology

The problem here is that, especially in the case of polymer filaments which tend to stick to the godet, individual filaments may break, or in the case of multi-colored filaments frictional effects on the godet lead to color inhomogeneities
