Definitions

  • the invention relates to a Luntentician for a drafting of a textile machine, with more than two guide funnels for feeding at least one roving to a pair of rollers of the drafting system.
  • lint guides are used to feed at least one sliver or at least one sliver to an input pair of the drafting system.
  • a textile machine such as a ring spinning machine
  • usually a plurality of drafting units are arranged side by side. The distance from drafting system to drafting system is also referred to as "division".
  • triple Luntentyp which can be used as a compressor in the drafting zone of the drafting system.
  • the known Luntenrise has three adjacent guide funnels, which have an opening at the top, so that the sliver can be inserted transversely to the fiber transport direction in the guide funnel.
  • Such a triple-lint leader is mainly used in the production of worsted yarn in the pre-draft field following the pair of infeeds of the drafting system.
  • the triple-lint leader has the advantage that it can be used both for the production of false twist and for the production of single yarn.
  • a fuse passes through the middle Guide funnel, while the two outer guide funnels remain empty.
  • Scheinzwim the two outer guide funnel are used and the middle guide funnel remains empty.
  • the textile machine can thereby be used very flexibly, since both flimsy yarn and single yarn can be produced without a large conversion effort.
  • the known triple Lunten2020 could not be used even before the input roller pair of the drafting system, if the guide funnels would be completely closed.
  • the distance between the two outer guide funnels of the known triple Lunten regardss.ist is too large for textile machines with small pitch. Due to the juxtaposed guide funnel the distance between the two outer guide funnel is not arbitrarily reduced, since the middle guide funnel is otherwise too narrow and loses its funnel shape.
  • the invention has for its object to provide a Lunten consider with more than two guide funnels, which can be used in drafting systems with small pitch both for the production of false twist and single yarn.
  • the object is achieved in that the guide funnel of Lunten concernss are at least partially at different heights.
  • the middle guide funnel can thereby have a sufficiently large inlet opening, which allows a good compression of the fuse.
  • the inlet openings of the guide funnels are not in a height, while the outlet openings of the guide funnels are at the same height. This will ensures that the transfer of the sliver from the leader to the idler pair of the drafting system is identical for each guide funnel.
  • the arranged at different positions inlet openings of the guide funnels have no adverse effect on the supply of Lunten, since the individual Lunten from the different roving bobbins anyway from slightly different directions enter the Lunten culinary.
  • the Lunten comprises on three guide funnels, which are at least partially not in a height.
  • the inlet opening of the middle guide hopper is advantageously - based on the stretching field plane - higher than the inlet openings of the other two guide funnel.
  • the sliver guide according to the invention also permits a simple and rapid conversion between the production of false twist and the production of single yarn in a textile machine with a small pitch, for example of about 70 mm.
  • the middle guide hopper is used, while in the production of false twist the two outer guide hopper are used. It is no longer necessary to replace the punch leaders.
  • the position of the Lunten réelleenen with the attached Lunten concernsn can remain in their position. In case of any intended traversing the Lunten transverse to the fiber transport direction, it may only be necessary to adjust the size of the traversing movement. However, the adjustment of the traversing movement takes place at a central point in the textile machine and thus represents no special effort.
  • Lunten concerns In order to enable a simple and cost-effective production of Lunten concernss, it is advantageous that the Luntenraising is made with all guide funnels in one piece as an injection molded part.
  • the sliver guide 1 shown in FIGS. 1 to 5 serves for feeding one or two slivers, rovings or slivers 2, 3 and 4 to a drafting system 5.
  • the drafting system 5 consists of several pairs of rolls, wherein in FIG. 1 only the two pairs of rolls 6, 7 and 8, 9 are shown.
  • the lower rollers 6, 8 are driven lower rollers 6 and 8 , to each of which a top roller 7 and 9 is pressed.
  • the lower rollers 6, 8 are formed as a sub-cylinder passing through in the machine longitudinal direction.
  • the Lunten 2, 3, 4 are fed to the drafting 5 in the fiber transport direction A and warped to their desired fineness. It can be provided in a manner not shown, the drafting 5 downstream of a pair of output rollers downstream of a compacting device in which the Lunten 2, 3, 4 compacted in compacting zones and compacted. Following this, the finished warped fiber bundles are fed to a common twist element.
  • the sliver guide 1 is fastened with a clamping device 10 on a slotted guide rail 11.
  • the Lunten concernssschiene 11 can be moved transversely to the fiber transport direction A in the direction of arrow B back and forth.
  • the traversing movement B serves to extend the service life of the upper rollers 7 and 9 provided with elastic covers.
  • the essential parts of the sliver guide 1 are three guide funnels 12, 13 and 14.
  • Each guide funnel 12, 13 and 14 has an inlet opening 121, 131, 141 and tapers in the fiber transport direction A funnel-shaped up to an outlet opening 122, 132, 142nd
  • the advantage of the Lunten concernss 1 with three guide funnels 12, 13 and 14 is that the Lunten researching 1 can be used both for the production of false twist as well as for the production of single yarn.
  • the Lunten researching 1 need not be exchanged or adjusted when changing from false twist to single yarn.
  • the two guide funnels 12 and 14 are used to simultaneously supply the Lunten 2 and 4 the drafting 5.
  • the two Lunten 2 and 4 are the nip 15 of the Input roller pair 6, 7 of the drafting system 5 through the two outlet openings 122 and 142 of the guide funnel 12 and 14 spaced supplied to each other.
  • the Lunten 2 and 4 remain spaced when passing through the drafting 5 and are warped separately from each other to the desired fineness.
  • the two warped Lunten 2 and 4 are then fed to a common twist element and twisted to a false twist.
  • no fuse 3 is supplied, that is, the guide funnel 13 remains unused.
  • the slivers 2 and 4 need to be removed from the guide funnels 12 and 14, and a new sliver 3 inserted into the middle guide funnel 13.
  • the sliver 3 is fed to the nip 15 centrally through the outlet opening 132. In this case, the guide funnels 12 and 14 remain unused.
  • Lunten concernsschiene 11 more Lunten concerns 1 are usually arranged at a distance of the pitch of the textile machine side by side.
  • the Luntencetschiene is connected at a central location with a drive which generates the traversing movement B, thereby moving all Lunten concerns 1 synchronously transversely to the fiber transport direction A.
  • the space at the adjacent drafting 5 are very cramped. It is therefore not possible to use a known triple-lunts leader.
  • the sliver guide 1 is therefore designed so that the guide funnels 12, 13, 14 are at least partially at different heights. It is preferably provided that the outlet openings 122, 132, 142 of the guide funnels 12, 13, 14 are at a height, so that in the transfer of the sliver 2, 3, 4 from the leader 1 in the nip 15 of the pair of input rollers 6, 7 are the same Conditions exist.
  • the inlet opening 131 of the guide funnel 13 for the central sliver 3 is higher than the inlet openings 121 and 141 with respect to the clamping line 15 or with respect to the stretching field plane.
  • the staggered arrangement of the inlet opening 131 allows a more compact construction of the sliver guide 1 with a reduced distance the guide funnel 12 and 14.
  • the width of the Lunten concernss 1 transverse to the fiber transport direction A can thereby be chosen so small that the Lunten réelle 1 in textile machines each, in particular, of course small pitch can be used.
  • the arrangement of the guide funnels 12, 13, 14 shows an advantageous embodiment.
  • the height positions of the guide funnels 12, 13, 14 with respect to the nip 15 can also be chosen differently depending on the requirements.
  • the Luntenraising 1 are required in relatively large numbers, it is advantageous for a rational production, when the Luntenraising 1 with all three guide funnels 12, 13, 14 is made in one piece as an injection molded part.
  • the clamping device 10 is integrally formed on the Luntennian 1.
