Definitions

  • the invention relates to a device for melt spinning and winding of synthetic threads according to the preamble of claim 1.
  • a generic device for melt spinning and winding of synthetic threads is known from WO 2004/015173 Al.
  • the synthetic yarns are extruded, cooled and bundled in parallel with each other from a polymer melt into a plurality of filament strands in a spinning device.
  • the threads are guided parallel in a treatment device preferably via godet systems, to be wound in the end in a winding machine parallel to coils.
  • the threads are thereby guided from melt spinning to winding with different thread distances to each other.
  • a spinning distance is held in the spinning device between the threads, which is essentially due to the nozzle divisions of the spinneret packets.
  • the filaments are brought together to be passed through the treatment means at a substantially smaller treatment distance.
  • the treatment distance is maintained substantially until before entering the winding machine between the threads.
  • a winding distance between the threads is to be maintained, which is essentially due to the coil widths of the coils of the individual winding units.
  • the group of threads is thus spread apart from the treatment distance to the winding spacing.
  • Fadenschreibungsmittel which deflecting or deflecting allows the individual threads to the respective desired thread spacing.
  • it must be ensured that the threads can be guided safely and without contact with one another in the devices, in particular in the godets of the treatment device.
  • care must be taken to ensure that the deflections generated by the thread guide means do not generate any inadmissible thread tensions due to high wrap friction.
  • certain deflection angles in particular at the externally guided threads, must be maintained in the transition areas. In the winding of the threads is aggravating added that any friction on the thread deflection leads to increase the yarn tension and thus affects the winding tension when winding the thread on the coil.
  • a device in which the distribution of the threads via a beneficiagalette which is arranged above the winding machines substantially transverse to a longitudinal axis of the winding machine in a horizontally oriented drainage plane.
  • Both known devices provide possibilities for guiding the threads in the treatment device with the least possible treatment distance parallel to one another and then dividing them onto the individual winding stations at a greater distance from one another.
  • the devices known from the prior art employ thread guide means in order to obtain certain threadlines and deflections.
  • the invention is achieved by the proviso that upon deduction of a guided parallel to a godet coat of thread in a center plane the drain points of the outer threads on the circumference of the godet in the direction of the center plane are shifted and thus a convergence of the threads during the expiration of the godet surface is inevitable. It has been found that these effects have different effects depending on the deflection angle. It was found that the run-off points of the running parallel threads on the godet surface at a maximum deflection angle of 15 ° to the middle level cause essentially unchanged or uncritical displacements of the drain points on the godet.
  • the task can be solved by the fact that the head thread guides the winding units, which are held in the vertically aligned feed level, are arranged directly in the yarn path of the foundedgalette such that upon deflection of the threads from the drainage plane formed by the godet, which rotates by 90 ° is formed to the inlet level, a deflection angle of 15 ° is not exceeded.
  • the distribution of the threads from the treatment device to the winding machine can thus be advantageously carried out without any additional thread guide means. Due to the restriction of the deflection angle, the treatment distance of the threads in the treatment device, and in particular on the sequence flag, which is decisive for the parallel guidance, remains unchanged. The threads are led after the expiry of the fabricatgalette directly into the traversing triangles of the winding units. The deflection of the threads and the limitation of the traversing range are determined by the head thread guide at the same time.
  • the constant position of the drainage points on the godet circumference, in particular of the outer most strongly deflected threads, can be further improved by the surface of the flow godet having a roughness in the range of a mean roughness value of 0.2 ⁇ m to 0.8 ⁇ m.
  • a range of 0.4 microns to 0.65 microns is set to obtain high adhesions of the filaments usually wetted with a spin finish on the godet surface.
  • Higher surface roughness leads to inadmissible slippage, which hinders the guidance and treatment of the threads.
  • even smaller center roughness values require a considerable manufacturing effort of the godet surface.
  • the development of the invention is particularly preferred in which the monument a guide means for guiding a plurality of parallel running threads is arranged, through which between the threads a thread spacing in the range of 2 mm to 8 mm is determined.
  • This thread spacing which is preceded by the guide means, thus represents the thread used for the treatment of the threads in the treatment device to be observed is yarn spacing. So let insbesonde ⁇ re realize at one or more times wrapped galettes short lengths and compact designs. Furthermore, even with a high number of threads, a distribution according to the invention without thread guiding means becomes possible.
  • the Stretrachette be arranged in the yarn path, which are formed for example by ceramic pins or kammformige ceramic guide.
  • the guide means can be formed directly by a plurality of radial guide grooves on the circumference of the contemplatgalette.
  • the threads are guided directly on the circumference of the godet in the guide grooves.

  • the treatment device preferably comprises a plurality of driven godets for guiding and stretching the threads, wherein the sequence godet is associated with at least one second godet in the thread run.
  • This allows the drainage godet to be fully integrated into the treatment facility without the need for additional guide godets.
  • godet systems can be used, which performs a partial drawing or a full drawing of the threads.
  • the threads are parallel vortex swirled synchronously.
  • the tension adjustments required to swirl the threads are made between the godets.

  • the embodiment of the device according to the invention is particularly advantageous in which the roller axes of the guide rollers have an inclination relative to the axis of the progress gages, depending on the respective deflection angle of the associated thread , This makes it possible to run the threads substantially at right angles to the guide rollers.
