Definitions

  • the present invention relates to the treating of yarns, threads, or the like with a liquid or gaseous medium during the spinning or twisting operation.
  • the enrichment with humidity cannot be directly controlled but depends exclusively on the extent to which the yarn or thread is able to absorb humidity.
  • the effect of the steam on the yarn or thread is limited to those sections of the yarn or thread during the spinning or twisting operation which rotate outwardly as balloon so that the centrifugal force acts counter to the absorption of humidity or, expressed differently, centrifuges absorbed humidity.
  • Still another object of this invention consists in a method of and device for humidifying threads and yarns which will make possible a uniform treatment thereof on all spindles.
  • Still another object of this invention consists in a method of and device for humidifying threads and yarns which will greatly decrease the formation of lint while improving the working conditions.
  • FIG. 1 illustrates an arrangement according to the invention in connection with a spinning or twisting spindle having a vertically adjustable hollow shank with a blow nozzle inserted into the upper end thereof.
  • FIG. 2 shows a modied arrangement according to the invention having a spinning or twisting spindle of a different design with a thread guiding member thereabove which is designed in a trough-shaped manner.
  • FIG. 3 shows a double-twisting spindle with a device for introducing treating media into the twisting point of the thread within the spindle.
  • a device for treating yarns, threads, or the like with a liquid, semiliquid, or gaseous medium, such as water, steam, wetting means, or the like, during the spinning or twisting operation in spinning or twisting machines as the spindles rotate about a nonrotatable and if desired vertically adjustable shank and ⁇ is characterized primarily tin that the shank is hollow over its entire length and that the treating medium is adapted to be blown through the shank into the twisting zone, preferably directly into the twisting point of the yarn or thread.
  • the treating medium may be so introduced into the yarn or thread that it acts not only upon the surface thereof but penetrates into the interior without having to rely on the absorbability of the material.
  • the yarn, thread or the like is treated in the twisting zone, preferably directly in the twisting point, i.e., due to the fact that the thread or yarn is exclusively in its twisting point subjected to the treatment by a liquid or gaseous medium, such as steam, wetting media, and the like, this medium is so to speak twisted into the core of the yarn or thread, which means that it penetrates the interior of the yarn from where the treating medium can distribute itself to the outside over the cross section of the yarn or thread.
  • the centrifugal force aids in a uniform distribution of the medium over the thread.
  • a spindle rail 1 through which extends a whorl sleeve 7 having its lower end provided with a thread 8 and connected to said spindle rail by means of a washer 10 and a n-ut 9 and a further washer 11 and supporting rings 12 and 13.
  • Sleeve 7 forms the inner race ring of ball bearings 14 .and 15.
  • the whorl proper 18 is held between the outer race rings 16 and 17 of said ball bearings 14 and 15 respectively. Seals in the form of discs 19 and 20 seal the said ball bearings toward the outside.
  • a bobbin sleeve receiving body 21 for receiving the lower end of the bobbin sleeve 2.
  • the bobbin sleeve 2 is held on the bobbin sleeve receiving body 21 by means of a spring 22 and ball 23.
  • the upper end of sleeve 2 rests against a cylindrical outer race ring 24 of a ball bearing 25 the inner race ring 26 of which is connected to a hollow shaft Z7 which latter extends downwardly through the whorl sleeve 7 and leads into a T- shaped fitting 28.
  • Fitting 28 communicates with a feeding line 29 for a treating medium or the like. By raising or lowering the feeding line 29, the free length of shank 27 which extends beyond the whorl and the bobbin sleeve receiving body 21 may be varied .in conformity with the length of the respective bobbin sleeve 2.
  • the upper end of the hollow shank 27 has arranged therein a blow or spray nozzle 3).
  • the mouth of said nozzle may in conformity with a further development of the invention be directed into the center of a thread guiding member associated with the spindle.
  • Such thread guiding member is shown in FIG. 1 in the form of a thread guiding eyelet 31 which by means of a supporting arm 32 is tiltable upwardly and downwardly about a substantially horizontal tube 33 extending alongside the machine.
  • the twisting point of the yarn or thread 6 is located within the thread guiding eyelet 31. ⁇ It is toward this point that the blow nozzle 30 is directed so that the liquid or gaseous medium intended for the treatment of the thread or yarn will precisely hit into the twisting point.
  • the intensity of the impact may be varied by axially displacing shank 27 more or less in conformity with the length of the bobbin.
  • the axial displaceability of shank 27 thus serves not only to adapt the arrangement to the length of sleeve 2 but also to vary the distance of the blow nozzle 30 from the twisting point of the thread or yarn V6.
  • the twisting point of the yarn or thread is for all practical purposes located in the plane of the thread guiding member, for instance the thread eyelet 31, and since the nozzle opening at the end of the hollow shank 27 extends directly along ⁇ the extension of the central axis of the thread guide 31, the treating medium is blown by the nozzle directly into the twisting point.
  • the sprayed medium can without difficulties be varied and metered, for instance by a simple valve in the feeding line, so that the quantity of the treating medium can be adjusted to a precise desired value in conformity with the requirement of the respective material being spun or twisted.
  • the quantity of the sprayed treating medium for instance steam
  • a relatively small quantity of treating medium for instance steam
  • the distance between the nozzle 3i) and the twisting point may be varied by vertically adjusting the shank 27, it is, of course, also possible to make the blow nozzle adjustable within the hollow shank 27, so that only the blow nozzle will have to be vertically adjusted without the necessity of vertically adjusting the shank 27.
  • this arrangement comprises a spinning or twisting spindle with a hollow holding shank 34 which is connected to the spindle rail 1.
  • shank 34 has its lower end connected to a T-shaped fittting 28 communicating with a feeding line 29 for the treating medium.
  • shock absorbing rings 35 By interposing shock absorbing rings 35, a threaded sleeve 36 is inserted through a bore in the spindle rail 1 and is connected thereto by means of a nut 37 and washer 38.
  • the threaded sleeve 36 surrounds with play the hollow spindle shank 34.
  • Sleeve 36 has its upper end provided with outwardly extending ange means 36a to which is connected a hollow conical body 39 which may support a spindle brake or the like, e.g., of the type disclosed in my copending application S.N. 217,789, tiled August 20, 1962, now U.S. Patent No. 3,137,118.

  • Mounted 0n body 39 and supporting the spindle shank 34 is a ball bearing 40 the outer race ring of which has mounted thereon a whorl 41 resting on ball bearing 40 by means of its shoulder 42.
  • Whorl 41 has an upwardly directed extension 43 for receiving a hollow conical spindle body 44 the upper end of which rests on a ball bearing 45 which is Xedly connected at the upper end of the hollow spindle shank 34.
  • the upper end of spindle body 44 is closed by a closure member 46 provided with a central bore through which extends a blow nozzle 47 inserted into the upper end of the hollow shank 34.
  • the blow nozzle 47 may be more or less moved out of the hollow shank 34 and may have its outer peripheral portion which is in sliding engagement with shank 34 provided with springurged ball means for engaging corresponding grooves in shank 34 so that the blow nozzle 47 will be held in its respective adjusted position.
  • Above the spindle there is provided a thread guiding member which in conformity with FIG.
  • Trough-shaped body 4S has a centrally located aperture 49 through which the yarn or thread 6 passes.
  • the treating or spraying medium or the like is sprayed primarily against the opening 49 so that a portion of the medium will be sprayed into the trough-shaped portion in which it will be distributed in a concentrated manner whereby the yarn or thread will be subjected to an additional treatment in the chamber below the twisting point.
  • the thread guiding member is adjustably supported in the same manner as described for the thread guiding member of FIG. l.
  • the modification illustrated in FIG. 3 comprises a double-twisting spindle. More specifically, by means of shock absorbing sleeves 35, the hollow shank 50 is connected to the spindle rail 1. The lower end of shank 50 has connected thereto a T-shaped fitting 28 connecting a feeding line 29 for the treating medium with the interior of shank 50. The upper end of hollow shank 50 has mounted therein a blow nozzle 51 the nozzle opening of which extends in axial direction of shank 50. Journalled on 4hollow shank 50 by means of the two antifriction bearings 52 is a whorl 53 having its upper end provided with a radially extending ange 54. Mounted on said ange 54 is a thread storage disc 55 provided with radially directed passages 56 for thread 6.
  • Disc 55 carries a radially extending overflow dish 57.
  • the central portion of disc 55 has a hub 5S having arranged therein two antifriction bearings 59 journalling the thread guiding member 60 in form of a tube.
  • This tube is similar to hollow shank 50 at a standstill during the twisting oph eration because a multi-pole magnet 61 surrounding shank 50 cooperates with a similar magnet 62 mounted on the thread guiding member 60. In this way, the magnets 61 and 62 prevent the thread guiding member 60 from rotating with the thread storage dish 55.
  • the upper end of the tubular thread guiding member 60 carries the hub 63 of the bobbin dish 64.
  • Dish 64 forms the carrier for the can 66 in which bobbin 3 rests on the bobbin sleeve 2.
  • the lower end of bobbin sleeve 2 rests on dish 64 while its lower inner wall portion engages on one hand a follower ring 69 on hub 63 of dish 64 and on the other hand its upper end rests on the cylindrical body 65.
  • a bearing body 70 is freely rotatable about the stationary tubular thread guide member 60 and is supported by cylindical body 65 which similar to the thread guiding member 60 stands still.
  • the bearing body 70 carries a thread runner 71.
  • the yarn 6 being unwound from bobbin 3 is treated in the same manner as described in connection with FIGS. l and 2 and the treating medium can likewise by a corresponding valve in the feeding line be precisely controlled and metered out.
  • the media are blown or sprayed ⁇ out axially through the blow nozzle 51 and exert an intensive effect directly onto the twisting point.
  • a certain humidifying action is exerted upon the yarn with the tube 6@ and within the thread storage disk 55 so that not only the core of the yarn absorbs the medium but also other sections thereof will absorb the humidifying medium whereby the treating medium will be fully uniformly distributed over the cross-section of the yarn, and the humidifying medium will uniformly distribute itself primarily from the core in cross-sectional direction over the cross section of the thread.
  • the method and devices according to the present invention furnish the possibility of precisely metering out the sprayed medium or the like and directing the same into the twisting point of the yarn or thread while the latter will absorb the humidifying medium to the desired extent. In this way a certain desired concentration of the humidifying medium will be assured, and the desired quality of the yarn or thread will be obtained which in turn makes possible a proper spinning and twisting operation.
  • the method and 6 device according to the present invention also assure not only an improvement in the thread or yarn but also considerably reduce the formation of lint thereby facilitating the working conditions.
  • the treating media mainly used for treating yarn or thread in conection with the present invention are water, wetting agents, anti- Statics, lm forming substances, especially synthetic materials, emulsied minerals, emulsified esters, wax, steam, chlorine, fluorine and hydrogen compounds, if desired under specific consideration of the pH value.
