Definitions
- the invention relates to the guiding of fibril bundles through a part of a spin-stretch texturing or stretch-texturing machine and the part of the spin-stretch texturing and Stretch texturing machine, or a spin stretching or stretch texturing machine according to Preamble of the three independent claims.
- the second to last group performs that despite the delivery width of the last bundle of fibrils from the roll to the texturing unit the group spacing to an acceptable degree can be provided to avoid the need for either long rolls or there is a risk that the fibril bundles of the last group adjacent fibril bundles of the previous ones still on the rollers Cover group.
- the aforesaid guides be it deflections between the roles or deflections before the entrance of each individual texturing nozzle, they have the disadvantage that they involuntarily an uncontrolled level of damage, e.g. Deformation of the fibril cross-section, generate on the individual fibril bundle, in this respect uncontrolled, than the deflection, especially in front of the entrance of the individual texturing nozzle, is different from texturing nozzle to texturing nozzle, so that texturing differences can ultimately arise in the individual fibril bundle, which may be in the Finished product, for example in carpets.
- level of damage e.g. Deformation of the fibril cross-section
- the swirl affects depending on the angular position the fibril bundle differs in the fanned arrangement. For example a layer of a fibril bundle may migrate along the fibril bundle counter the surface line of the roll due to the twist while another Due to the swirl location this hike still supports what leads to a restless Run the corresponding bundle of fibrils.
- the task is determined by the measures in the characteristic part of the independent Claims resolved.
- FIG. 1 shows a pair of stretching rollers 1, also called a duo, with the individual stretching rollers 1A and 1B, on which individual fibril bundles 6 in groups 6.1, 6.2 and 6.3 are grown are, which, in combination with at least one other, preceding Stretching roller pair can be stretched in a manner known per se.
- the groups, as shown in FIG. 2, are separated from one another by a distance A. held.
- the fibril bundles 6 of the last group 6.3 are separated by a the lower guide deflection 2 provided for the stretching rollers 1A and 1B and also a little further forward, sitting against the free end of the rollers 1A and 1B, too between the stretching rollers 1A and 1B located upper leading deflection 3 deflected and guided in such a way that the last fibril bundle group 6.3 the roller 1A a larger distance B to the previous group 6.2 on the Have stretching rollers than the distance A between the fibril groups 6.1 and 6.2.
- the deflections 2 and 3 have a groove for each fibril bundle.
- the delivery point is an imaginary one to the roll axis parallel straight line 15, also called surface line, on which the fibril bundles side by side to run.
- the fibril bundles 6 entering the texturing unit 4 are at the entrance of the Texturing unit 4, as shown in Fig. 2, due to the spreading of the fibril bundle between the delivery point 15 and the entrance to the texturing unit 4 at the entrance deflected each texturing nozzle.
- the deflections of the fibril bundle 6 on the between the rollers 1A and 1B located lower deflection 2 and upper deflection 3 and the deflection on Entry into the texturing unit 4 can, as mentioned above, due to the friction on the fibril bundles one different from fibril bundle to fibril bundle and also cause unwanted damage that causes unevenness in the finished yarn.
- the individual texturing nozzles 8 arranged in a fan shape in such a way that those with dash-dotted lines shown longitudinal axes 16 of each individual texturing nozzle 8 coaxially with, with Dashed lines shown connecting line 17, which is from the delivery point 15 extends to the exit of each individual texturing nozzle 8.
- the connecting lines 17 correspond simultaneously to the run of the individual fibril bundles 6 from the delivery point 15 to each individual texturing nozzle 8.
- This fan-shaped arrangement of the texturing nozzles 8 can, as in FIGS. 3 and 4 shown on all previously mentioned deflection guides between the rollers 1A and 1B and in front of the texturing nozzles 8.
- the texturing nozzles 8 each deliver a textured bundle of fibrils to a cooling drum 5 specifically in a single, per fibril bundle, provided on the cooling drum 5 Cooling track.
- the cooling drum 5 is known per se, for example from EP 0 310 890 B1 Element and not described here.
- FIG. 4 shows only one half 4.1 of the texturing unit 4 from FIG. 3.
- the other Half 4.2 has been removed or opened in the direction III, as shown in FIG. 3. This only applies to the course of the fibril bundles 6 and the individual texturing nozzles 8 to be able to display better.
- the individual texturing nozzles 8 via a conveying medium distribution channel 13 fed with a medium, so that due to a known injection pump principle, the fibril bundle 6 by means of the medium sucked into the individual texturing nozzles 8 and through the conveying part 9 in the texturing part 10 are conveyed, in which the fibril bundles form a plug respectively textured fibril bundle and from there each into a single cooling track 11 of the cooling drum 8 are promoted.
- the fluid is through a fluid supply channel 14 and via internal, here Channels, not shown, introduced into the fluid distribution channels 13.
- the invention is not based on the arrangement of the fibril bundle course shown the role 1A in Fig. 4 restricted. Basically, it is according to the invention around a fibril bundle guide which essentially has no major deflections caused as, for example, that which is in Fig. 4 from the top surface line the role 1A to the delivery point 15, which on the one hand depends on the friction between Fibril bundle and surface of the roller 1A and on the other hand of the thread tension in the individual fibril bundle 6, generated by the suction force of the individual Texturing nozzle, and further depends on the surface condition of the roller 1A.
- the fan-like arrangement of the individual texturing nozzles 8 can be varied.
- FIG. 5 shows an enlargement of FIG. 4, in which the arrows D and D.1 a twist direction of the individual fibril bundles, which corresponds to the connecting line 17 guided from the delivery point 15 into the corresponding texturing nozzle 8 become.
- the individual texturing nozzles contain means around one so-called false twist in the fibril bundle 6, between the inlet of the texturing nozzle and the delivery point 15, namely according to CH 680 140A5.
- these twist means are provided here so that for the first three filament bundles, in 5 seen from right to left, a right-hand twist D (also called clockwise), seen in the direction of the filament bundle and for the other 3 filament bundles, from seen right to left, a left spin D.1 (also called counterclockwise) in Seen the direction of the filament bundle.
- the right twist of the first three filament bundles mentioned has the tendency to Filament bundle on the roll 1A from the free end of the roll 10 against the clamped Let the end wander and until the thread tension no longer allowed. This creates a stable thread layer for these three filament bundles on the Dispensing point 15, and thereby also between the dispensing point 15 and the inlet channel 20 of the corresponding texturing nozzles 8.
- insert parts 19 are through a bore 21 of the nozzle halves 4.1 and 4.2 held and guided and, like the nozzle halves 4.1 and 4.2, are made from two halves. In the conveying direction of the fibril bundle, these insert parts 19 are by means of their flange 22 on a support 23 of the corresponding half of the texturing unit 4.1 and 4.2 overlying.
- the aforementioned halves of the insert parts 19 are by screws, not shown here fixed with the corresponding half of the texturing unit.
- the screws are in slots (not shown) guided so that the corresponding insert parts when closed Texturing unit together by turning, slightly according to the length of the slot can be moved to change the effect of the swirl.
- spiral channels 25 and the nozzle channels 24 on the one hand being variable to design and on the other hand by the ability to slide the insert 19 to design, it is possible to create the swirl in the fibril bundles vary without affecting the amount required for texturing of texturing and conveying air.
- the invention is not based on the type of swirling shown and described restricted in the inlet of the texturing nozzles, but there is the possibility of any a swirl generator known or not known (not shown) in the corresponding Thread run after the roller 1a delivering the fibril bundles to the texturing nozzles, in front of the texturing nozzles, seen in the course of the thread, around the one leaving the roll Fibril bundle to give a twist in the given direction.
