Definitions

  • the invention relates to a method and an apparatus for producing a Self-twisting yarns according to the preamble of claim 1 and claim 11.
  • Such methods and devices are from the prior art, for example according to the British patent GB 1 144 614, the German patent application DE 26 37,208 and U.S. Patent 4,279,120.
  • Two rovings twisted in this way then become so stirred together that the two yarns automatically due to their tendency to turn back twist a so-called self-twist yarn, the Areas of the two rovings without twist or with less twist advantageously Are out of phase.
  • the roving threads often break because this due to the friction on the deflection and union eyes heavy wear subject. This wear also leads to a reduced strength of the twisted self-twist yarn.
  • Figure 1 shows schematically a device for producing a self-twist yarn.
  • the device essentially comprises a drafting system 11 for producing two unrotated ones Rovings 2 and 3, a false twisting device 4, through which the rovings 2 and 3 Periodically alternating areas with S and Z rotations are issued, as well as one Twisting device 12 in which the two twisted rovings 2, 3 are brought together that they twist into a self-twist thread 1.
  • the drafting system 11 is in the embodiment of Figure 1 as a roller drafting system two stretching rollers 13, 14 are formed.
  • the wrong turning device 4 is a known Nitschel device. This has two essentially cylindrical, Nitschel rollers 7, 8 arranged parallel to the axis and rotating about their axes. The Nitschelwalzen 7, 8 rotate in opposite directions to each other and thereby promote the rovings 2, 3 clamped between them. In addition to their rotation, the two Nitschelwalzen 7, 8 in the axial direction between two limit positions. Through this Axial oscillation, the two rovings 2, 3 carried out are twisted and obtained thus a rotation.
  • the rovings In a direction of oscillation, the rovings get an S twist, in a Z-rotation in the opposite direction of oscillation. Since the Nitschelwalzen 7, 8 in the rovings get to the reversal points of their axial movement Instants no rotation. Therefore, the alternating areas are with S and Z turns separated by areas without rotation or areas with less rotation.
  • false turning device 4 shown in FIG. 1 with nitsch rollers 7, 8 can also be wrong-turn devices of the clamp type, such as in DE 198 27 870, or false twists, which prevent the rovings from twisting Issue air turbulence (as described, for example, in US Pat. No. 4,279,120) for use come.
  • one of the two rovings 2 becomes over a deflection roller 5 guided on a guide roller 6.
  • the other roving 3 is after Pass through the wrong turning device 4 directly to the guide roller 6 where the rovings 2, 3 are merged at the merging point 13.
  • 3A is a Self-twisting yarn shown, which is produced by twisting two rovings 2, 3 together was, the rovings 2, 3 were brought together so that the areas without Rotation are directly opposite, i.e. are in phase. This also means that twisted self-twist yarn 1 the areas without twisting each on the same Job. Since the rovings are less strong in the areas without twist, the self-twist yarn also has lower strength at these points.
  • the Areas without rotation have a phase distance of ⁇ .
  • the phase distance ⁇ can be a fraction of the period of the alternating areas with S and Z rotations, where a 360 ° period through the distance L from two areas with the same direction Rotation is defined.
  • the phase difference ⁇ is approximately 90 °.
  • the rollers 5 and 6 are disc-shaped cylinders formed, one in the cylinder jacket to improve the leadership of the rovings 2,3 Guide notch 14 is formed.
  • the guide notch 14 prevents slipping sideways the rovings 2, 3 from the guide surfaces 5a, 6a of the rolls 5, 6.
  • the two rovings 2 and 3 are merged at the merging point 13 on the guide surface 6a of the guide roller 6.
  • the rollers 5 and 6 Due to the distance between the axes of rotation 5b and 6b of the rollers 5 and 6, the additional path can be set, the roving 2 between the false twist 4 and the Merging point 13 compared to the other roving 3 has to cover.
  • the rollers 5 and 6 are mounted so that their axes of rotation 5b and 6b in the plane, which is spanned by the two rovings 2 and 3, are mutually displaceable.
  • the yarn strength of the self-made yarn 1 produced it has also proven to be proven particularly advantageous if the two rovings 2, 3 in the area of False turning device 4 and in the area in front of the guide over the deflection roller 5 in the run essentially parallel to one another, the roving 3, which does not have the Deflection roller 5 is guided in the area between the false twisting device 4 and the Junction point 13 runs in the same direction as the twisted one Self-twine 1.
  • This course of rovings 2 and 3 before they are brought together enables twisting without the rovings being under tension or sticking to one another the guide roller 6 can get caught. This ensures a constant distance between the untwisted zones of rovings 2 and 3 in twisted self-twist yarn 1.
  • the twisteddicazwirngarn, 1 in the yarn running direction after the merge point 13 over a rotatably mounted pressure roller 10 are guided.
  • This enables a clean and tension-free guidance of the twisted self-twisting yarn 1.
  • this can Roving 3, which is not deflected via the deflection roller 5, in the yarn running direction C. the merging point 13 via a pressure roller 9 on the guide surface 6a Guide roller 6 are performed.
  • a tension-free reunification the rovings 2 and 3 contribute significantly to improving the yarn strength of the Self-twist yarn 1 and also causes one over the length of the self-twist yarn 1 constant distance between the unrotated zones. This in turn improves the Properties of fabrics woven with such self-twist yarns 1 with regard to their Strength and in terms of their visual impression.
  • the present invention has the advantage that the rovings by the deflection and the junction cannot be worn or damaged.
  • eyelets occurs namely, due to the friction of the yarns on the eyelets, wear on the rovings 2, 3, before they are merged into self-twist yarn 1.
  • the Hooks 2, 3 get caught in the eyelets, which often leads to thread breaks during the Manufacturing process comes. This leads to frequent and undesirable interruptions in the Manufacturing process.
  • the rovings 2, 3 can become caught in the eyelets Unevenness in the distance between the untwisted zones in the self-twist thread 1. This causes an unfavorable appearance of fabrics woven with such self-twist yarns.
  • Self-twisted yarns are produced, which, compared to conventionally produced, one have up to 60% higher tensile strength.
