Definitions

  • the invention relates to a spinning machine according to the preamble of the independent claims 1 and 2. Further, it is also proposed for use in compaction spinning machines according to claim 4.
  • Such spinning machines either have a drafting system with a special outlet roller which is connected to a suction device, or it is connected to a conventional two-stage drafting system with three pairs of cylinders operating under vacuum compression device.
  • the compression takes place on a moving with the fiber structure air-permeable compression element, which is acted upon from the inside with negative pressure, wherein the compression is effected by the inflowing transversely against the fiber structure suction air.
  • the US-A-5,577,298 describes a Doppelriemchenstrecktechnik, which contains a mechanical compressor between the outlet opening of the Riemchen Insert and the nip of the delivery cylinder pair, which mechanically compresses the sliver.
  • a special guide is provided for this purpose in the main draft of the drafting system and / or before reaching the compacting device, which allows drifting apart of the drawn fibers less than in conventional drafting systems, without imposing significant changes in direction on the individual fibers.
  • this is achieved by a deflection element, the surface of which is at least coated by a part of the fibers, preferably so that all the fibers of a fiber structure are deflected in the same way and / or the same direction.
  • a prismatic deflection - rod-shaped achieved with substantially uniform cross-sections, which is arranged transversely to the flow direction of the fiber stream and is arranged in the longitudinal direction of the drafting cylinder.
  • This guide element can be arranged immediately before the emergence of the fiber structure on a compression element.
  • the direction change of the fiber structure by the guide element is preferably 1.5 to 5 °.

  • the outlet cylinder 2 is designed in this embodiment as a compression element 19, that is, as an internally evacuated, perforated drum.
  • the Oberriemchen 5 wraps around the one hand, the second upper roller 3 ', on the other hand, a spacer 32 which sits on the cage 30.
  • a guide member 34 is arranged, which, as shown in FIG FIG.
  • the fiber structure 11 deflects a little, whereby a tight guidance of the fibers of the fiber structure 11 is achieved and in particular shorter fibers are prevented from dissolving from the dressing.
  • a round rod is used in particular with a diameter between 3 and 6 mm as a guide element 34.
  • the guide element 34 is arranged as close as possible to the surface of the outlet cylinder 2 or the compression element 19, with a distance of less than 1 mm.
  • the fiber structure runs after a deflection by the guide member 34 by a few degrees on the surface of the compression element 19, wherein the looping path between the nip of the third top roller 2 'and the fourth top roller 1' is located on the compression element 19.
  • a screen 19 'above the compression element 19 ensures a guidance of the incoming suction air as parallel as possible to the axis of the outlet cylinder 2.
  • the fiber structure is then preferably screwed by means of a ring spinning device 40 and wound onto a yarn package.
  • yarns in the fineness range Ne 3 to 100, preferably 3 to 50, in particular 3 to 30, can be spun.
  • the template may consist of all known spinnable fiber materials also with high short fiber content, especially carded cotton, also MMF, PES, blends. Thanks to the guide 34 become good yarn quality values reached.
  • the reference numerals in the Figures 2 and 2a apply analogously to those in FIG. 1 ,
  • FIG. 3 shows two embodiments for the attachment of the guide 34 in the drafting system.
  • the cage 30 for guiding the Oberriemchen 5 is stationary with second upper rollers 3 'to the mentioned load device 10, but pivotally mounted.
  • this extends over the entire length of a portion of the cage 30 in FIG. 3 .
  • the ends of the guide element 34 are held by holding elements 340, 340 '.
  • the holding elements 340 are fixedly attached to the ends of the cage 30, for example by means of fastening elements 342 in the form of pins or screws.
  • the holding elements 340 may be made, for example, as leaf springs made of spring steel. They can be snapped laterally into the ends of the cages by means of fastening pins 342 in bores in alignment with the fastening elements 342.
  • a relatively short guide member 34 by means of two holding elements 340, 340 ', sit at the ends tabs 342, plugged at a spacer 32 on the right longitudinal edge of the cage 30.
  • the riders 342 sit directly next to riders 320 of the spacer 32.
  • the spacer serves to guide the Oberriemchens 5, which is deflected by the deflector 33 between the riders 320.
  • the tabs 342 may be like the tabs 320 of the spacer, shown in perspective, executed, with a greater distance between the tabs 342 than between the tabs 320.
  • a holding member 340 is seated in the in FIG.
  • the guide element of the guide 34 is, as already mentioned, a preferably circular-cylindrical prismatic element.
  • the guide 34 can also be fastened directly on the deflection element 33.
  • FIG. 4 Another embodiment of a drafting system with a compression device is in FIG. 4 shown. From the drafting system 1 a only the central cylinder 3 and the outlet cylinder 2 are pressed by means of the loading device 10 top rollers 3 '(second top roller) and 2' (third top roller) shown. Between the third top roller 2 'and the fourth top roller 1' sits another roller 27, which serves to drive the fourth top roller 1 'through the third top roller 2'. Unlike the arrangement in FIG. 1 the discharge cylinder 2 is not designed as a compression element; this is on the left next to it, wherein a vacuum system 15 is wrapped by a compression element 19 in the form of an air-permeable belt.
  • the compression element 19 is moved forward by the fourth top roller 1 'with the fiber structure 11 or the yarn 25 along the compression zone 13.
  • the compression of the fiber structure 11 in the compression zone 13 takes place along a suction slot 17, is sucked through the air in the vacuum system 15.
  • the axes 8 and 21 of the third top roller 2 'and the fourth top roller 21 are held by the loading device 10.
  • the fiber structure 11 is guided by a Oberriemchen 5 on the second upper roller 3 'and a Unterriemchen 4 on the central cylinder 3 in the main drafting zone of the drafting system, between the straps 4 and 5 in a known manner a guide 34 is arranged, with which the fiber structure around a very small angle between 1.5 and 6 ° is deflected.

From the nip 23 between outlet cylinder 2 and the third top roller 2 ', which is pressed against this, until reaching the compression zone 13, the fiber structure 11 can be supported by a further guide element 34'.
  • This guide element may be formed, for example, as the described guide element 34 as a circular cylindrical rod or, as indicated by dashed lines, as a flat, more or less flat guide member extending at least in the region of the fiber structure 11 along the spinning machine.
  • the first guide element 34 improves, as already described above, the cohesion of the fibers in the main drafting zone of the drafting between central cylinder 3 and outlet cylinder 2, while the second guide element 34 'serves as a kind of guide table for the fiber structure between outlet cylinder 2 and compression element 19.
  • the second nip 24 between the compacting device 1 and the fourth upper roller 1 ' limits the twist in the yarn 25, which results from a nachgeördneten spinning device.
