Definitions

  • the invention relates to a device for intermingling multi-filament yarns, with a channel serving for guiding the yarn, into which at least one blowing nozzle for blowing compressed air opens out and through which the yarn to be intermingled is passed such that it passes the channel wall in front of and touched behind the mouth of the blow nozzle and runs in the mouth at a distance from the duct wall.
  • Such a device is known for example from DE-AS 14 35 605.
  • the yarn touches the channel wall on the side of the blowing nozzle in the inlet area and on the side opposite the blowing nozzle in the outlet area. It runs, so to speak, diagonally through the channel and can swing freely between the two points of contact.
  • This course of the yarn to be intermingled through the channel has the disadvantage that the yarn is located where the blowing nozzle opens, approximately in the middle of the channel cross-section, where the eddies of the air flow generated by the blowing nozzle are relatively weak.
  • Such vortices preferably form adjacent to the channel wall.
  • the yarn is to be lifted from the duct wall to a sufficient extent by means of the compressed air jet emerging from the blowing nozzle and is swirled in the free cross section of the duct.
  • the turbulence occurs primarily through intensive air vortices that form in the canal walls.
  • the success of this device obviously depends on the fact that the deflection angle of the yarn, the tension of the yarn, the pressure of the compressed air supplied by the blowing nozzle and the yarn feed speed are exactly coordinated. If this does not happen, there is a risk that the yarn remains in constant contact with the channel wall during its passage through the channel, whereby the intermingling process is considerably impeded. If the yarn is in contact with the channel wall over a longer path during its passage through the channel, there is also the risk that the yarn will be damaged by the wall adhesion effects that occur.
  • the invention proposes, starting from the device of the type mentioned at the outset, that the channel wall on the mouth side of the blowing nozzle in front of and behind the blowing nozzle is provided with projections slightly projecting into the channel cross section, which protrude the yarn to be swirled in front and behind the blow nozzle close to the duct wall.
  • the peculiarity of the invention is that here for the first time the yarn passing through the channel is guided close to the channel wall. This ensures on the one hand that the yarn cannot lie against the channel wall as it passes through the channel, which would hinder the intermingling of the filaments. On the other hand, it is ensured that the yarn remains very close to the channel wall over most of its movement path through the channel without touching it. In this way, the yarn remains in the area of the particularly intensive eddies close to the wall, but does not touch the wall, so that the harmful wall adhesion effects cannot occur. There is always an air cushion between the yarn and the channel wall, which prevents the yarn from touching the channel wall.
  • An expedient development of the invention provides that the projections hold the yarn to be swirled in front of and behind the blowing nozzle at a distance of 0.2 to 1 mm from the channel wall. It has been found that the swirling results obtained are best if these dimensions are observed. It is also provided that the channel is widened laterally in the region of the projections. This lateral widening compensates for the cross-sectional narrowing of the channel caused by the projection, so that there can be no pressure build-up in the inlet area and in the outlet area of the channel, which would hinder the passage of the yarn.
  • yarn guides are arranged in front of the inlet-side projection and behind the outlet-side feed, which guide the yarn at an angle to the longitudinal direction of the channel, in such a way that the yarn always lies against the projections. This ensures that the yarn passing through the channel is always oriented exclusively on the projections.
  • the channel is arranged in a channel block made of highly wear-resistant ceramic, the projections being integral components of the channel block.
  • the channel is formed as an indentation in the top of the channel block and is covered at the top by a cover block movable between an open position and a closed position, such that the channel is open at the top over its entire length.
  • Fig. 1 shows schematically an end view of the device according to the invention
  • Fig. 3 shows a section through the channel block in
  • the device according to the invention shown only schematically in its essential parts in the drawing, has a channel block 1 made of highly wear-resistant ceramic and a cover block 3 which can be displaced in the direction of the double arrow 2 and which is also made of highly wear-resistant ceramic.
  • a channel 4 which serves to guide the yarn, which is formed as an indentation in the upper side of the channel block 1 and is closed at the top by the overlying cover block 3.
  • the two projections 6a and 6b each have the shape of a rounded bead projecting into the channel cross section, so that the yarn can run into the channel 4 without hindrance and run out of the channel 4.
  • the channel 4 is provided on both the inlet side and the outlet side, specifically where the projections 6a and 6b are, with lateral widenings 7a and 7b, in such a way that the overall open cross section of the channel does not decrease in the region of the projections. This is to prevent a pressure build-up in the area of the inlet or outlet of the channel 4.
  • yarn guides 8a and 8b In front of the inlet-side projection 6a and behind the outlet-side projection 6b there are yarn guides 8a and 8b, respectively, which guide the yarn at an angle (cf. FIG. 3) such that the yarn always lies against the projections 6a and 6b.

Abstract

L'invention concerne un dispositif de tourbillonnement de fils continus multiples. Ce dispositif comprend un canal (4) destiné au guidage du fil et où aboutit, sur le côté, au moins une buse soufflante (5) destinée à souffler de l'air comprimé. Le fil tourbillonnant est guidé dans le canal de telle façon qu'il touche la paroi du canal, avant et après la zone d'aboutissement de la buse soufflante (5) et s'étende, en amont et en aval, à une certaine distance de la paroi du canal. Selon l'invention, pour améliorer les résultats de tourbillonnement reproductibles, la paroi de canal est dotée de protubérances (6a, 6b), au niveau de la zone d'aboutissement de la buse soufflante (5), notamment avant et après la buse soufflante (5), vu dans le sens de défilement du fil. Ces protubérances font légèrement saillie dans la section transversale du canal et guident le fil tourbillonnant avant et après la buse soufflante (5) à une faible distance de la paroi du canal.
