Definitions

  • the invention relates to a roller assembly for a device for producing a Self-twisting yarn according to the preamble of claim 1, an apparatus for manufacturing a self twisting yarn comprising such a roll arrangement and a method for the Production of a self-twisting yarn according to the preamble of claim 12.
  • a generic method for producing a self-twisting yarn and a Apparatus for carrying out this method is known from DE 100 32 708 C1.
  • first at least two rovings are alternately provided with areas of and Z rotations separated by areas without rotation.
  • These rovings are then combined on a guide roll so that they automatically twist together due to their tendency to reverse, the areas without Rotation in the twisted self-twisting yarn have a phase difference.
  • These Phase difference is adjusted by placing one of the rovings over a pulley and from There is led to the leadership role, making this roving compared to the other Roving has a longer way to go until it becomes unified with the other Roving is coming.
  • the invention is based on the object, a method and a To provide apparatus for producing a self-twisting yarn with which a twisted self-twisting yarn can be produced, which is characterized by a uniform Phase course of the unrotated portions of the rovings along the twisted Self-twisting yarn distinguishes.
  • the invention proposes a roller assembly for a Apparatus for producing a self-twisting yarn having the features of claim 1 and a set of roller assemblies according to claim 5.
  • preferred Embodiments of the roller assembly can be found in the dependent claims 2 to 4.
  • each The roving gives false twists, so that each roving is alternating areas with Has S and Z turns. Then these rovings are brought together in such a way that they twine themselves to the self-twisting yarn.
  • the Reverse tendency of the rovings provided with incorrect rotations exploited It is known, that the strength of the twisted twisting yarn is quite different from the Phase of the areas without rotation of the two rovings depends. The rovings will be Therefore, as a rule, merged so that their areas without rotation out of phase lie.
  • Figures 1 and 2 this is illustratively contrasted with the figure 1 the Situation shows, in which the two rovings 2, 3 arranged parallel next to each other are where the areas without rotation (0) face each other or in phase.
  • Figure 2 shows the higher for the production of a self-twisting yarn Strength preferred situation in which the areas without rotation (0) of the two rovings 2, 3 out of phase.
  • the phase difference between the unrolled areas of the rovings 2, 3 is denoted by ⁇ below.
  • Figure 7 shows a perspective view of an apparatus for producing a Self-twisting yarn 1 from two rovings 2 and 3.
  • the rovings 2, 3 are first in a Not shown here drafting generated and then parallel next to each other running guided in a false twisting device 10.
  • the false twisting device 10 the rovings 2, 3 periodically alternately issued areas with S and Z turns, which are separated by areas without rotation (0).
  • the rovings 2, 3 After going through the Wrong turning device 10, the rovings 2, 3 in a twisting device 11 so brought together, that they twist together because of their backward tendency and to twist together to the self-twisting yarn 1.
  • the false twisting device 10 is as Nitschel device formed. This has two substantially cylindrical and Axially parallel arranged Nitschelwalzen 12, 13 on.
  • the Nitschelwalzen 12, 13 rotate on the one hand in opposite directions to each other about their axes of rotation 12a, 13a, which parallel are arranged to each other.
  • the rotational movement of the rovings 2, 3 by the Nitschelwalzen 12, 13 promoted.
  • the rovings In an oscillation direction, the rovings get an S-twist and in the opposite Zziallationscardi a Z-rotation. Since the Nitschelwalzen 12, 13 at resting at the reversal points of their axial movement, the rovings 2, 3 receive them Time points no rotation. Therefore, the alternating areas are with S and Z turns through areas without rotation (0) or areas with less rotation separated.
  • Wrong turning devices are used, such.
  • the twisting device 11, in which the rovings 2, 3 then twisted together comprises a roller assembly, which a first guide roller 5, a second Deflection pulley 7 and a guide roller 6 comprises.
  • This roller arrangement is in FIG. 3 shown schematically and in Figures 4 to 6 in detail.
  • the rollers 5, 6 and 7 are each mounted in the above arrangement on a base plate 4.
  • Thread guides 8 and 9 are respectively Thread guides 8 and 9 arranged.
  • the yarn guides 8, 9 serve the roving 2 on the Outer circumference of the guide roller 6 and the roving 3 on the outer circumference of the first Steering pulley 5.
  • the yarn guide 8 with respect to its associated Guide roller 6 is arranged so that the roving 2 is deflected so that it only punctiform bears on the merge point 22 on the outer circumference of the guide roller 6.
  • the yarn guide 9 serves the roving 3 on the outer circumference of the first guide roller fifth to lead, wherein the first bearing point of the roving 3 on the guide roller 5 in the following designated by reference numeral 33.
  • Points 22 and 33 have each one same distance to the Nitschelwalzen 12, 13. From the contact point 33 wraps around the one roving 3 then a substantial part of the circumference of the second guide roller 7 (at the arrangement shown in Figure 4, the wrap angle is about 270 °).
  • the Path difference between the attachment point 33 and the merge point 22 determined the phase difference ⁇ between the unrotated portions of the rovings in Twisted self-twisting yarn. For this reason, the exact adherence to the Points 22 and 33 are of particular importance throughout the duration of the proceedings Concerning the uniformity of the manufactured self-twisting yarn 1.
  • the roller assembly comprises the Base plate 4 and an intermediate plate 14. On the base plate 4 are the two Deflection rollers 5 and 7 and the guide roller 6 are arranged. The second guide roller 7 is while a bearing 15 rotatably mounted in a receiving plate 16 which on the base plate. 4 is attached, stored.
  • the pulleys 5 and 7 and the guide roller 6 are respectively Cylindrically shaped, wherein in the cylinder jacket in each case a guide groove 5a, 6a or 7a is cut.
  • the guide grooves are used to run over the respective role Roving 2, 3 on the cylinder surface of the deflection or guide rollers 5, 6, 7 to hold and prevent slipping.
  • Thread guide 8 and 9 On the base plate 4 are still the two Thread guide 8 and 9 attached, which in the embodiment described here as Thread guide eyelets are formed. Alternatively, thread guide pins can be used become.
  • the guide roller 6 here is the yarn guide 8 and the first guide roller 5 is associated with the thread guide 9.
  • the yarn guides 8 and 9 are in this case arranged so that they are in Garnlaufraum C immediately before the guide roller 6 and the guide roller 5 are.
  • the base plate 4 is attached via a quick release on the intermediate plate 14.
  • a quick release on the intermediate plate 14 is the quick release by two permanent magnets 17, 18 formed, which are inserted in recesses 19, 20 of the intermediate plate.
  • the Metallic base plate is characterized by the magnetic force of the magnets 17, 18 on the Intermediate plate 14 held.
  • this magnet quick release can also other quick fasteners, such. B. a bayonet closure, are used.
  • This holder 21 serves to hold the intermediate plate 14 in the device for Production of a self twisting yarn as shown in FIG.
  • a set of roller assemblies which consists of a plurality of Roller assemblies consists, as shown in Figures 4 to 6 and 9.
  • the individual role arrangements of this sentence are identical in their structure to those in However, they differ in the FIGS. 4 to 6 and 9 Distance D between the axis A7 of the second guide roller 7 and the plane E, which by the axes A5 and A6 of the first guide roller 5 and the guide roller 6 is defined. through of the quick release, it is possible to have one roller assembly against another Replacing roller assembly in a simple and fast way.
  • the Twisted self-twisting yarn (1) immediately after leaving the guide roller (6) is guided over a run-out yarn guide. This will provide a stable guidance of the twisted self-twisting yarn 1 allows.
  • the outlet yarn guide is here also like the thread guides 8 and 9 as a thread guide eye or as a thread guide pin educated.
