Definitions

  • the invention relates to a device for interlacing multifilament threads, which are guided in a number of parallel game channels arranged in parallel, into each of which at least one transverse blowing nozzle opens, in particular for interlacing warp threads as they travel from the creel to the warping machine.
  • the warp threads coming from the gate are passed through a channel plate which, in a matrix arrangement, one above the other and next to one another, a plurality of cylindrical thread channels, each of which has a smaller diameter ceramic thread guide eyelet on the outlet side are.
  • Radial holes form blowing nozzles. They are supplied with blown air from a cavity provided in the duct plate.
  • the invention has for its object to provide a swirling device of the type described in the introduction, in which the yarn channels are arranged to save space.
  • warp threads that are swirled during warping should be bent as little as possible from a flat warp thread group with warp threads running in parallel.
  • the slot-like yarn channels are delimited by alternately arranged plates and spacer elements, which form a nozzle rod in their entirety, the yarn channel side walls of the slot open to the outside by the top and bottom surface of two adjacent plates and the bottom of the slot are formed by the end face of a spacer element that at least one of the two plates has a cavity communicating with an air supply duct and at least one bore emanating therefrom and opening in the side wall as a blowing nozzle and that thread supports are arranged in the channel direction in front of and behind the blowing nozzle keep the thread at a distance from the slot base in the area of influence of the blow nozzle.
  • the yarn channels can be arranged close to each other. Their width is determined by the thickness of the spacer elements and their distance by the thickness of the plates.
  • the threads are easy to insert because the slots are open to the outside. The noise is much lower than with cylindrical gam channels.
  • the nozzle rod also results in a stable construction that is easy to handle.
  • the plates have plane-parallel end faces and the spacing elements are formed by interposed washers.
  • the components of the nozzle rod are simply constructed.
  • the intermediate disk can be a seal separating the slot from the air supply duct.
  • double-function washers can be punched out of foils, for example.
  • the spacer elements are formed by integral protrusions on the plates.
  • the projections can engage, in particular, in depressions of a small depth in the adjacent plate.
  • the air supply channel is formed by openings in the plates and spacing elements and the cavities from pockets opening through plates are covered on both sides except for the blowing nozzles of plate material.
  • Flat pockets are sufficient to supply the blow nozzles, so that the plates need only have a small thickness.
  • the nozzle rod has two rows of slots of the same type on opposite sides of the air supply duct. In this way, for a given plate thickness, two slots can be accommodated with only a slight dislocation, which makes it possible to treat twice the number of threads, even though only slight bending of the threads is necessary.
  • the plates should preferably consist of ceramics, in particular oxide ceramics. This results in a long service life.
  • the ceramic plates can be produced using the usual molding processes and then fired.
  • thread supports are formed by rods which partially protrude into the slots and which penetrate the nozzle rod.
  • One rod forms many thread supports.
  • the rods can serve as clamping bolts.
  • the double function of the clamping bolts simplifies the overall structure.
  • the slots can be provided with an exit barrier on their open side.
  • the outlet barrier can be formed by at least one wire which runs through mutually aligned bores in the plates. Such an exit barrier prevents the thread from blowing out. However, it can be easily released if a thread is to be inserted into the slot.
  • the nozzle rod is fastened on one side to a carrier, the air supply channel running inside the nozzle rod being connected to an air supply line in the carrier. Since the mechanical connection and air supply are coupled to each other, the structure is simple.
  • a sealing piston is axially displaceable in the air supply duct.
  • the sealing piston can separate those blowing nozzles from the rest of the air supply duct, the slots of which are not covered with threads. This prevents unnecessary air consumption.
  • the piston is held on an adjusting spindle which emerges from the nozzle rod at the free end and is provided with an actuating device there.
  • the operating device for example a rotary knob, is easily accessible.
  • two nozzle rods can be arranged at approximately the same height on opposite sides of the carrier.
  • the distance of the plate center planes from each other should be at most 5 mm and preferably less than 4 mm. You only need a width of about 1 mm or less per fader.
  • the design of the interlacing device is particularly recommended if the at least one nozzle rod is connected downstream of a warp thread treatment device on which the warp threads have been treated as a flat warp thread group. If the warp threads have already been brought together in one plane for the purpose of treatment and have therefore undergone an even treatment, it is of great interest to separate the threads as little as possible and, above all, not to provide unevenly strong bends, because otherwise the uniform Image of the warp thread sheet is lost.
  • the warp thread treatment device is a hot stretching system which ensures a uniform stretching of the threads. If the threads were subsequently subjected to very different mechanical loads, the uniformity of the warp thread group would be lost.
  • the superimposed nozzle rods are arranged approximately symmetrically above and below the connection plane between a distributor device and a collecting device.
  • bobbins 1 In Fig. 1, a larger number of bobbins 1 is shown in a creel 2 provided with thread brakes.
  • Warp threads 3 are drawn off from the bobbins, which first pass through an eyelet reed 4 and then a gathering reed 5 before they enter a hot drawing system 6.
  • This can have a structure according to DE-OS 33 28 449, for example.
  • the warp threads 3 are introduced with a set of tension rollers 7, heated with the aid of heating devices 8, deflected via a roller 9 on which the stretching takes place, additionally heated by means of a further heating device 10 and finally drawn off with a roller set 11 at a higher speed than the supply takes place with the help of the roller set 7.
  • the last roller 12 of the roller set 11 serves as a distribution device for the warp threads, which now enter a device 13 for intermingling the threads.
  • This device has two nozzle bars 14 and 15, each of which has two swirling rows of slots 16 and 17 or 18 and 19.
  • Distribution reeds 20 and 21 are used to distribute the warp threads.
  • Collection reeds 22 and 23 and a collecting device 24 are also used to collect the warp threads in the form of a reed. This is followed by further units 35, for example an optical warp thread monitoring, an oil device etc. Then the warp threads are fed to a warping machine M, where they are wound on warp beams.
  • FIG. 2 shows a carrier 26 which rests on a foot 27.
  • the carrier 26 is hollow.
  • the cavity is connected to a blown air supply line 29 via a reducing valve 28.
  • the nozzle bars 14 and 15 are attached on one side of the carrier 26, and corresponding nozzle bars 14a and 15a are mounted on the opposite side at the same height. These nozzle rods are supplied with the blown air from the cavity of the carrier 26.
  • each nozzle rod is composed of a plurality of plates 30 and as an intermediate discs formed spacers 31 together, which lie alternately against each other.
  • the spacer elements 31 (Fig. 4) have a lower height than the plates 30 (Fig. 3), so that in the assembled state open to the outside, serving as Gamkanal slots 36 and 37 result, which form two mutually parallel rows of slots 16, 17 .
  • Thread supports 32 to 35 are formed by rods passing through the nozzle rod in the longitudinal direction and projecting into the slots 36, 37, which here simultaneously form tensioning bolts with which the plates and spacer elements are connected to one another and to the carrier 26. Bores 38 and 39 in the plates 30 receive wires which each form an exit barrier 40, 41 and prevent warp threads 3 from emerging from the slots 36 and 37.
  • Each plate 30 has a circular opening 42 and each spacer 31 has a circular opening 43, which together form an air supply channel 44.
  • a pocket-shaped cavity 45 extends radially outward from this air supply channel 44 and, on the opposite side, a further pocket-shaped cavity 46. It is covered on both sides by plate material and leads to bores which open as a blowing nozzle 47 or 48 in a side wall of the slot 36 or 37.
  • FIG. 6 shows how a piston 49 is arranged in the interior of a nozzle rod 14 in the air supply duct 44 and blocks it.
  • the piston 49 is axially displaceable on an adjusting spindle 50 when an actuating device 51 is actuated at the free end of the nozzle rod 14.
  • the piston 49 has a thread which is in engagement with the thread of the adjusting spindle. In this way, all cavities 45, 46 and blowing nozzles 47, 48, which are located between the piston 49 and the free end of the nozzle rod, are separated from the air supply. Slots not covered with threads can therefore be excluded from the air supply.
  • the nozzle rod 14 is arranged so that the two rows of slots 16 and 17 are arranged approximately symmetrically above and below a connecting plane between the distributor reed 20 and the collecting reed 22.
  • the two nozzle rods 14 and 15 in turn are arranged approximately symmetrically above and below the connection plane between the roller 12 serving as a distributor device and the reed 24 serving as a collecting device.
  • the warp threads 3 are therefore angled as little as possible from the common plane. They are therefore with a certain tension on the thread supports 32 to 35.
  • the interlaced warp threads therefore have a high degree of uniformity.
  • the blowing nozzles 47 and 48 each radiate air approximately to the middle of the thread. The air is thrown back from the opposite plate in the manner of the baffle plate principle. It can then exit laterally and upwards without generating much noise.
  • the plates 30 have a width of 3.5 mm, for example, and the spacer elements 31 have a width of 0.5 mm. In this way there are a total of four slots 36 and 37 per 4 mm, so that there is about 1 mm space per thread. This is a very good distance for warp threads.
  • the plates can also be designed in such a way that blowing nozzles 47, 48 connect to the cavity 45, 46 on both sides.
  • every second plate can be made of full material, i.e. without blowing nozzles and cavities.
  • FIGS. 7 and 8 reference numerals increased by 100 are used for corresponding parts.
  • the spacing elements 131 are designed as one-piece projections on the plates 130 and engage in recesses 152 in the neighboring plate.
  • the recess 152 has a lower height than the projection, so that the slots 136, 137 remain between the plates.
  • additional clamping bolts 153, 154 are provided, so that the thread supports 132 to 135 are formed by unloaded rods. If the plates are made of ceramic material, sufficient sealing of the air supply duct 144 can be achieved, even if the pressure is 4 bar and more.
