Definitions
- the invention relates to a method for stripping and stretching a plurality of freshly spun threads according to the preamble of claim 1 and to a device for stripping and stretching a plurality of freshly spun threads according to the preamble of claim
- the freshly spun threads are, after cooling for further treatment, preferably guided as a group of threads on an arrangement of several godets with driven godet sheaths.
- the godets of the godets can be heated or unheated in order to draw, stretch and relax the threads after spinning.
- FDY fully drawn filaments
- two different methods and devices for drawing and drawing the spun threads are known in the prior art.
- the threads are guided together with several wraps on a godet unit.
- the godet unit has at least one driven godet casing and a freely rotatable overflow roller in order to be able to guide the yarns with in each case a plurality of wrappings on the godet casing and the overflow roller.
- the godet unit is preferably operated with two heated Galettenmänteln.
- Such godet units thus require long projecting galette coats, the s vom cause a not insignificant drag air flow due to relatively large circumference.
- shielding sheets between the godet shells of a godet unit in order to shield the yarn loops on the godet unit from drag air.
- the invention is characterized in that the guide track formed between two adjacent godet shells remains for the free guidance of the threads essentially without external action and in particular without the action of a towing air, which is inevitably produced by rotating the godets.
- the drag air flows generated by the adjacent godet coats are kept away from the threads guided between the godets.
- the device according to the invention has, between two adjacent godet sheaths, a shielding plate for shielding a thread guide, which crosses a connecting line between the center axes of the forked sheaths. In this way, depending on the respective thread guide of an S-guide or a Z-guide, a corresponding inclination of the shielding plate can be used.
- the threads are preferably guided according to an advantageous variant of the method with a short distance to the shield.
- a parallel guidance is preferably desired, so that the threads are guided in the range of 2 mm to 20 mm next to the shielding plate. It is essential here that the thread run from the godet casing and the yarn feed to the adjacent godet casing is included as far as possible in the shielding.
- the device of the invention provides this development, in which the shield with a tail in a soab stood next to the godet shell of the upstream godet and is held with a drain end in a final distance in front of the godet shell of the downstream godet.
- the drag air flows can be kept away from the thread guide between the godets even in the vicinity of the godet coats.
- the device according to the invention is preferably designed with the lateral spacing between the godet shell and the shielding plate in the range from 2 mm to 20 mm.
- the tapered thread is shielded briefly to the emergence of the threads on the surface of the godet, the final distance between the godet shell and the shielding plate is in the range of 1 mm to 10 mm.
- the heated godet shells With the heated godet shells, it is customary to arrange them inside a pallet box isolated from an environment. Basically, such galette booms have the disadvantage that the mutual drag airflows within the godet box still partially amplify and lead to turbulence.
- the method variant is particularly advantageous in which the Schleppluftströmungen generated by the godet coats within a godet box are collected in one or more free spaces within the godet box. Such free spaces can be advantageously used for calming the air flows generated within the godet box.
- the device according to the invention is further developed in such a way that a godet box for thermal insulation of some godet sheaths is provided, which encloses a free space at least next to the godet shroud.
- free spaces represent an enlargement of the godet box, but with the advantage of a homogenization of the inner air flow.
- Such free spaces also favor a homogenized room climate of the godet box.
- the threads are preferably closed by means of an inlet plate in the region of the inlet opening Galettenbox and out with the aid of a discharge plate in the area of the outlet opening of the godet box.
- the process variant in which the drawn threads are led to a shrinkage treatment with a partial wrap around the circumference of a plurality of heated godet shells and wherein the Schleppluftströmungen the godet sheaths is prevented by at least further shielding from the freely guided threads, is particularly advantageous.
- the threads are guided with the lowest possible thread tension and thus with the lowest possible thread speed difference on the circumference of the godet sheaths, so that the stability of the thread guide can be substantially improved by shielding the towing air.
- the shrinkage treatment usually takes place with the drawing speed, which represents the highest circumferential speed in the godet system.
- the device according to the invention is preferably designed such that, in the case of several godet boxes, a passage opening is assigned at least one guide plate for shielding a thread guide which penetrates the passage opening. This even thread transitions between the godets from adjacent boxes can be safely performed.
