Definitions

  • the present invention concerns a device to apply liquids for treat ⁇ ing yarns.
  • said device consists of an oiler for textile 5 yarns, especially an oiler for weft yarns fed to weaving machines such as looms. Therefore, although hereinafter reference is made above all to the oiling of yarns, it is however understood that the device can be used to apply any other treatment liquids.
  • oiling helps at times to correct the irregularities determined by previous yarn treatments.
  • small acetone residues left on the staple cause the volatilization of the oily substance, applied in the yarn finish, from the outermost layers of the reel and from its ends; this creates great differences in yarn behaviour when inserting the weft yarn from a same reel and it evidently gives rise to serious weaving difficulties in the 20 loom.
  • the application of a thin layer of oil can, in such cases, be a valid remedy.
  • liquid paraffin oils has subsequently allowed to overcome these drawbacks, making it also possible to add emulsifying and/or antistatic agents.
  • a treatment has generally been carried out with a device comprising a vessel for the paraffink; liquid, and a roving or band of felt or of textile material, or like, which extracts the oil from the vessel by capillarity and spreads it by direct contact over the
  • the present invention now offers a valid solution to this problem, by supplying a device to apply liquids, particularly oil, on yarns - to be preferably mounted upstream of yarn feeders for looms - comprising a
  • said oil distribution unit comprises, on one hand, a brush among whose bristles the yarn is guided by suitable guide means and, on the other hand, means to draw close, or move apart, the base supporting the brush and at least part of the means to guide the yarn.
  • Said yarn guiding means generally comprise a pair of guide eyelets and two guiding rolls joined through an oscillating lever, one of said rolls being fixed in correspondence of the fulcrum of said oscillating lever and the other roll being lifted and lowered by said lever.
  • Said means to draw close, or nove apart, the bast- supporting the brush and part of the yarn guiding means preferably consist of two adjustment screws, one acting on said base and the other one acting on the roll apt to be lifted and lowered by said lever.
  • the device of the present invention also comprises means apt to remove the weft yarn from the bristles in case of occasional loom stops.
  • Such means may consist of a spring, loaded with a force which is less strong than the yarn tension component acting on the roll apt to be lifted and lowered by the oscillating lever.
  • the oil level in the tank can be regulated by an overflow.
  • Fig. 1 is a plan view of the device to apply oil on weft yarns. according to the present invention
  • Fig. 2 is a cross-section view of the same device, along the line II-II of fig. 1 ;
  • Fig. 3 is a cross-section view of the device, perpendicular to the previous one, along the line III-III of fig. 2.
  • the: device of the present invention com ⁇ prises a tank 1 for the oil , having at the top a central opening which is closed by a cover 2.
  • the central part of the cover 2 comprises in turn a quadrangular opening 3- from which projects the end of a brush 4 plunged into the oil contained in the tank 1 up to the level L.
  • the brush 4 comprises a support, base 5 and groups of bristles 6.
  • the base 5 of the brush 4 can be lifted or lowered by an adjusting screw 7. operated from the top. which acts on said base.
  • the oil is introduced into the tank 3 through a hole S. normally closed during operation by a plug Q.
  • eyelets 10, 11 - which can also be self-threading eyelets - to guide the weft yarn 12.
  • the guiding of the weft yarn 12 is completed by two rolls 13. 14- of ceramic material, which are glued onto a lever IS hinged onto a fulcrum 16 in correspondence of the roll 1,3. Under the roll 14 the lever 15 bears onto an adjusting screw
  • the whole device is supported by an articulated clamp 1Q, inserted onto a bracket 20 which is in turn fixed onto a support 21. typically forming part of the structure of a yarn feeder for looms.
  • the tank 1 is filled with oil through the hole 8, up to the level L, and the plug 9 is then applied thereon.
  • the weft yarn 12 is caused to slide through the first eyelet 10, then over the first roll 13. then between the bristles 6, then over the roll 14. and finally through the second eyelet 11.
  • the oil contained in the tank 1 rises by capillarity through the bristles 6 of the brush 4 and, soaking them, spreads onto the surface of the yarn 12 sliding through said bristles, thereby oiling the; same.
  • the amount of oil being spread on the weft yarn 12 can be regulated according to its characteristics, and to weaving requirements or to the use being made of the yarn, by acting onto the adjusting screw 17- This latter either lifts or lowers - by way of the lever 15 - the roll 14 in respect of the roll 13, so as to cause the weft yarn 12 to slide in a more or less inclined position, either upwards or downwards, and be: plunged among the bristles 6 to a smaller or greater extent, allowing to vary its oiling degree according to requirements.
  • the constant sliding of the weft yarn 12 through the bristles 6, or over the same, leads to the wear of such bristles.
  • This drawback can be overcome by acting on the adjusting screw 7. which allows to lift the ba ⁇ se 5 of the brush 4 ?
  • the solution according to the present invention proves to be particularly advantageous, as it allows to efficiently apply on the weft yarn - with a 0 very simple and economic system - oil, or any othe:r treatment liquid. hence solving in a very efficient manner the problem of wear of the oil distribution unit.
  • the possibility to adjust the petition of the base 5 supporting the brush 6, leads to a far more rare replacement of said brush than in the devices of prior art.
  • the possibility 5 to adjust the position of the roll 14 allows to simultaneously weave, with the same device, yarns of highly different characteristics, it being possible to thus proportion the amount of oil spread on the yarn 12.
  • screws 7 and/or 17 could be automatically operated to take into account the wear of the bristles 6 and/or the oil ⁇ ing requirements, for instance ⁇ in relation to yarn speed and/or to the braking effect meant, to be produced on the yarn in the loom yarn feeder.

Abstract

Un dispositif permettant d'appliquer des liquides, notamment de l'huile, sur des fils (12), destiné de préférence à être monté en amont des prédélivreurs de fils dans les métiers à tisser, comprend un réservoir (1) pour l'huile appliquée sur le fil de trame (12), et une unité de distribution de l'huile. Celle-ci comprend d'un côté une brosse (4), le fil de trame (12) étant guidé au travers des poils de ladite brosse par un système de guidage approprié (10, 11, 13, 14), et de l'autre côté un système (7 et/ou 17) qui rapproche ou écarte la base (5) supportant la brosse (4) et au moins une partie du système (13, 14) de guidage du fil de trame (12).
