Definitions

  • the invention relates to a drafting unit for a drafting unit of a spinning machine, in particular for an air-jet spinning machine, wherein the drafting unit has a first top roller and a spaced-apart second top roller along a sliver transport direction, which are used to stretch a sliver transported from the first to the second top roller in cooperation with corresponding assigned lower rollers are provided, the respective axis of rotation of the first and second upper roller extending transversely to the sliver transport direction.
  • the present invention further relates to such a drafting system.
  • a drafting system during the spinning process for example using a ring spinning machine or an air-jet spinning machine, makes it possible to produce a sliver with defined production speeds, which is drawn to the final fineness.
  • Air spinning is a spinning process that has now become established alongside the well-known spinning processes such as ring spinning, compression spinning and rotor spinning, in which a yarn can be spun through the controlled use of air flow in an air spinning unit.
  • the drafting system is generally located upstream of the spinning unit, for example in the air-jet spinning machine, the air-jet spinning unit, in the fiber transport direction.
  • Such a drafting system is, for example, from the document EP 2 865 792 A1 known.
  • the warped sliver in the air-jet spinning machine passes through a nozzle block of the downstream air-spinning unit to an inlet opening of a hollow spinning spindle assigned to the air-spinning unit.
  • the free ends of the sliver are wrapped by a directed air flow circulating around a conical spindle head and wrap themselves spirally around the core fibers as the thread is drawn into the spindle.
  • the uniformity of the sliver used to produce the yarn is essential for the quality of the yarn obtained in this way. Reliable parallelization of the fibers of the sliver is particularly important.
  • the several pairs of rollers that are usually present in a drafting system and are arranged one behind the other, each consisting of a lower roller and an upper roller, are used to stretch and transport the sliver in the direction of the inlet opening of the hollow spinning spindle, whereby the peripheral speed of the roller pairs increases in the transport direction of the sliver in order to achieve a defined distortion.
  • the high rotational speeds of the output roller pair of the drafting system produce, as in Fig.
  • the present invention is intended in particular to provide a drafting unit for a drafting unit of a spinning machine, for example an air-jet spinning machine, by means of which fiber deflection from the sliver caused by a rotational air flow of a pair of rollers can be minimized.
  • the present invention proposes a drafting unit which has a first upper roller and a second upper roller spaced apart therefrom along a sliver transport direction, which are provided for stretching a sliver transported from the first to the second upper roller in cooperation with correspondingly assigned lower rollers, the respective Axis of rotation of the first and second top roller extends transversely to the sliver transport direction.
  • the present invention is characterized in that an apron cage that can be subjected to negative pressure is arranged between the first top roller and the second top roller for the circumferential guidance of an air-permeable apron together around the apron cage and an apron top roller.
  • the apron top roller can be formed by the first top roller or a third top roller assigned to the apron cage, which is arranged on the same side as the first and second top rollers with respect to the sliver to be transported is.
  • the apron cage has at least one passage opening that can be subjected to negative pressure for applying suction air to the sliver running between the first and second top rollers via the air-permeable apron.
  • the proposed invention it can be ensured in a simple manner that the fibers that otherwise emerge from the sliver in the gusset area due to the drag currents and/or outgoing flows remain in the sliver and can be carried along with the sliver in the sliver transport direction. This ensures a particularly high quality of the sliver, improved yarn uniformity and thus the possibility of producing a qualitatively improved yarn.
  • the through opening has a smaller distance from the second top roller along the sliver transport direction than from the apron top roller.
  • the arrangement close to the second top roller promotes the effect of holding the fibers together in the sliver in the gusset area of the downstream pair of rollers.
  • the through opening is to be arranged close to or in a gusset area between the top roller and the sliver in order to be able to counteract the drag flows and the outgoing flows directly with a counterforce caused by suction air.
  • This preferred arrangement also has an advantageous effect on the cohesion of the fibers in the sliver in the gusset area.
  • the through opening is formed at an end of the apron cage opposite the second top roller. This allows an arrangement closest to the second top roller.
  • the through opening is preferably designed as an elongated hole extending transversely to the sliver transport direction.
  • the area of the sliver that can be acted upon by suction air can be enlarged in a direction transverse to the sliver transport direction, whereby a further improved cohesion of the fibers in the sliver in the gusset area can be achieved.
  • the strap cage can have more than one through opening.
  • the through openings can thus be selected and provided as required in their respective dimensions and the arrangement opposite the sliver in order to ensure a further improvement in the cohesion of the fibers in the sliver in the gusset area.
  • the through opening is arranged to face the sliver between its opposite edge sides.
  • a suction flow directed towards the middle of the sliver can act on the sliver via the air-permeable strap, whereby the cohesion of the fibers, in particular the edge-side fibers, in the sliver in the gusset area can be further improved.
  • the passage opening is indirectly coupled to the strap cage. This indirect coupling is achieved when the through opening is formed by a means which can be connected to the strap cage and can be directly subjected to negative pressure.
  • the second top roller forms an output top roller for the drafting system comprising the drafting unit.
  • the apron cage which can be subjected to negative pressure, is therefore arranged in a main drafting area of the drafting system.
  • the apron cage that can be subjected to negative pressure is arranged in a pre-drafting field, which is upstream of the main drafting field in the sliver transport direction, in order to ensure the cohesion of the fibers in the sliver at this point in the gusset area of a pair of rollers upstream of the output roller pair in the sliver transport direction.
  • the preferred alternative arrangement already promotes an improvement in the quality of the sliver compared to a previously known drafting system.
  • the additional arrangement also has an advantageous effect in that there is cohesion along the sliver transport direction almost over the entire length of the drafting system of the fibers in the sliver in the respective gusset areas is made possible by pairs of rollers belonging to the drafting system.
  • a drafting system for a spinning machine in particular an air-jet spinning machine, which has a first pair of rollers comprising a first upper roller and a first lower roller and a second pair of rollers formed by a second upper roller and a second lower roller.
  • the first and second pair of rollers are spaced apart from one another along a sliver transport direction and are provided for stretching a sliver transported from the first to the second pair of rollers.
  • the respective axes of rotation of the first and second pair of rollers i.e. the axes of rotation of the assigned lower and upper rollers, extend transversely to the sliver transport direction.
  • the drafting system is characterized in that an apron cage that can be subjected to negative pressure is arranged between the first pair of rollers and the second pair of rollers for the circumferential guidance of an air-permeable apron together around the apron cage and an apron top roller, the apron top roller being arranged upstream in the sliver transport direction by the first top roller, i.e. an upstream first pair of rollers or a third top roller assigned to the apron cage is formed, which is arranged between the same side as the first and second top rollers with regard to the sliver to be transported.
  • the apron cage has at least one passage opening that can be subjected to negative pressure for applying suction air to the sliver running between the first pair of rollers and the second pair of rollers via the air-permeable apron.
  • the apron top roller, the first and second top rollers and the apron cage form a drafting unit according to one of the embodiments described above.
  • a sliver compaction device which is used to compact an output top roller a stretched sliver passing through a drafting system is provided in a drafting system, the sliver compacting device having an apron cage which can be subjected to negative pressure for the circumferential guidance of an air-permeable apron together around an apron top roller and the apron cage, which has at least one through opening which can be subjected to negative pressure.
  • the use is characterized in that the sliver compacting device is arranged between a first pair of rollers and a second pair of rollers of the drafting system in such a way that the apron cage guides the air-permeable apron together around the apron top roller and the apron cage, the apron top roller passing through the first top roller of the in Fiber transport direction arranged upstream first pair of rollers or a third top roller assigned to the apron cage is formed, which is arranged on the same side as the top rollers of the first and second pair of rollers with respect to the sliver to be transported.
