Definitions

  • the invention relates to an air bar laying device for weaving machines according to the preamble of claim 1.
  • the arrangement of the catching and threading nozzle which is offset parallel to the longitudinal axis of the nozzles has the disadvantage that a relatively long weft end is required for safe threading into the eyelet, which results in a relatively wide selvedge.
  • This arrangement of the nozzles also requires a relatively heavy support for the nozzles.
  • the object of the invention is to create a device which is improved with regard to these aspects.
  • the invention achieves the object according to the characterizing features of claim 1.
  • a catch nozzle with a catch channel lying in the axial extension of the nozzle and a threading nozzle with a catch channel lying in the axial extension of the nozzle with intersecting air jet axes are arranged in a carrier, which is a narrow construction of the device for threading the weft end into the Eyelet or enables the hook of the groin needle and thus short weft ends or narrow selvedges. Dirt particles such as thread flight are reliably removed from the carrier's gap and from the trap channels and the formation of an air jam is prevented.
  • the compact arrangement allows the mass of the nozzles and the carrier to be reduced, which is why faster movements are possible for positioning the carrier.
  • a shed 31, in which a weft thread 21 is inserted, is formed by high shed warp threads 32 and deep shed warp threads 33. Not shown in FIG. 1 are edge warp threads or a holding nozzle, respectively. the weft end up to the cutting and threading process hold.
  • the selvage needle 11a with tip 13 and eyelet 14, which is rotatable about the pivot point 12, can be inserted into the shed 31, as indicated by the position of the selvage needle 11b.
  • the eyelet 14 can also be open-sided as a hook. For the sake of clarity, only the threading nozzle 41 with the fluid supply line 43 and the catch channel 42 lying axially opposite the threading nozzle 41 are shown.
  • the weft thread end 21a resulting after the cutting process is blown through the threading nozzle 41, for example by means of a fluid flow indicated in the fluid line 43, for example with air, through the eyelet of the groin needle 11b into the catching channel 42.
  • FIG. 2a shows in detail the elements of a further air bar laying device which are important for the process of threading the weft thread end into the eyelet of the bar laying needle 11.
  • the exemplary embodiment of this groin layer with holding nozzle 53 is usually arranged on the fabric edge at the end of the weft insertion.
  • the carrier 54 is usually pivotable. Slidably mounted in the warp direction, so that all elements attached to it can be moved away after the insertion process, so as not to hinder, for example, the weaving reed stop.
  • the threading nozzle 41 and the catch channel 42 lying in the axial extension of the nozzle as well as the catch nozzle 44 with the catch channel 45 lying in the axial extension of the nozzle are arranged in the carrier 54 with intersecting air jet axes.
  • the intersecting air jet axes can touch in the room or can also be arranged such that only the projection of the spatial axes onto a plane gives a touching intersection.
  • the groin needle 11 in the eyelet of which the weft thread is threaded.
  • Edge warp threads or, for example, a holding nozzle 53 hold the weft thread 21 until it is cut by a thread scissors 52.
  • a yarn positioning wire 5 is provided on the carrier 54 and determines the position of the weft thread 21 in the gap 55 of the carrier 54.
  • a weft thread 21 positioned in this way and held by the holding nozzle 53 can be seen in FIG. 2b.
  • the shed 31 with high shed warp threads 32 and deep shed warp threads 33 can also be seen.
  • the weft thread 21 previously struck by the reed can be twisted by crossing the warp threads. integrated in the tissue by changing the subject.
  • the catching nozzle 44 is charged with air, the weft thread 21 is cut by the thread scissors 52, and the end of the weft thread is blown into the catching channel 45. A portion of the weft end comes to lie in front of the outlet of the threading nozzle 41.
  • the groin needle 11 is then pivoted into the gap 55 of the carrier 54 such that the eyelet 14 comes to rest over the opening of the catch channel 42.
  • the threading nozzle 41 As shown in FIG. 2d, the weft thread end 21a is pulled out of the catching channel 45 by the air flow and blown into the catching channel 42 via the eyelet 14.
  • the weft end is then inserted into the shed 31 by the selvage needle 11 and the selvedge is thus formed.
  • the position of the high shed warp threads 32 and of the deep shed warp threads 33 of the shed 31 are always shown in the same position in FIGS. 2b-2d.
  • the position of the warp threads or the compartment 31 can of course also change during the cutting and insertion process.
  • the strip laying device according to the invention can of course be operated not only with air but also with other fluids such as water.
  • Fig. 3 shows a top view of the gap 55 in the carrier 54 as well as the arrangement of the yarn positioning wire 51, the opening of the catching nozzle 44 and the opening of the catching channel 42.
  • the openings 42 and 44 are preferably arranged in parallel or approximately parallel to the course of the warp threads, in short To achieve weft ends.
  • the position of the opening of the catching nozzle 44 and of the threading nozzle 41 is also selected such that the weft thread end 21a to be conveyed advantageously lies in the air jet of the nozzle.
  • Each of the intersecting air jet axes of the two nozzles 41 and 44 can lie in a plane parallel to the direction of the warp threads, parallel to the insertion direction of the weft thread 21 or in a plane of an intermediate region between these two positions.
  • the inlet openings of the catch channels 42 and 45 are usually arranged axially aligned with the opposite nozzle, and the further course of the catch channels can be designed in a straight or curved shape.
  • the arrangement of the two nozzles 41 and 44, as shown in FIGS. 2a-2d, can also be exchanged for one another, so that the catch nozzle 44 comes to lie at the top and the threading nozzle 41 at the bottom.
