Definitions

  • the invention relates to a spinning device according to the Preamble of claim 1.
  • DE 40 36 119 describes a device for producing a twisted thread known in which a guide member inside a nozzle block is arranged. That from a drafting system outgoing sliver is drawn into the nozzle block and near the inlet opening of a spindle around the sliver exposed to rotating air flow and thereby rotated.
  • a Fiber strand guide takes the place as a so-called false core the inner fibers of the sliver, causing the fibers along the outer peripheral surface of the fiber strand guide need to move to the inlet port. The Fibers uncontrolled by the effect of the rotating air flow exposed.
  • the sliver is then sucked into the spindle by means of a suction air flow, and so on to create a thread.
  • the invention is therefore based on the object generic device for sliver guidance so too improve that an improved manufacturing process is possible is.
  • This task is characterized by the characteristics of the Claim 1 solved.
  • the sliver guide is outside of a imaginary center line of the running sliver arranged so that at least some of the fibers are on the inside Surface of the sliver guide is passed, the Sliver guide from spaced apart Fiber guiding elements are there, the free passage of a Allow part of the fibers as a core fiber bundle.
  • the Spinning device be designed so that the core fiber bundle not when passing the sliver through the sliver guide is deflected. With such a form of training can high production speeds can be achieved.
  • the core fiber bundle comprises at least 10%, preferably 20% to 40% of the fibers.
  • fiber guiding elements that form the core fiber bundle can be arranged in parallel in the longitudinal direction oriented fibers and thus improve the yarn properties. At the same time, an increase in Production speed enabled.
  • at least part of the is preferably Fiber guiding elements are needle-shaped. This allows that Applying particularly low pressure to the sliver. Fiber guiding elements that are used as a flat plate or needle-shaped are easy to manufacture.
  • a Training the fiber guide elements as parts of a single Body, the fiber guide elements from a hollow cone are generated by introducing openings also simple and therefore inexpensive to manufacture and allows an improvement of yarn values especially at high Production speeds. The introduction of the openings can by eroding or drilling.
  • the training can also take the form of a compact sliver guide device with sliver channel and Fiber guiding elements take place, the sliver guiding device consists of one piece. Through the compact, one-piece design becomes easy to use and enables easy and quick interchangeability.
  • the fiber guide elements evenly distributed around the sliver, in particular concentric or symmetrical, and the Minimum distance of the fiber guide elements from the imaginary The center line of the running sliver is slightly less than half the diameter of the sliver.
  • the Fiber guide elements each have the same shape to a approximately uniform effect over the scope of the To achieve sliver spread.
  • the inlet opening is preferably at least on the outlet side the sliver is designed as a slit-shaped sliver channel, on its opposite long sides the Fiber guide elements are arranged, the Fiber guide elements at least approximately parallel to that imaginary center line of the sliver so that they extend part of the fiber stream from the channel to the near to Cover the input opening of the spindle and therefore largely withdraw from the action of the rotating air flow.
  • This is the whereabouts of a core fiber bundle with predominantly parallel and longitudinal fibers in largely undisturbed Arrangement allows.
  • Spinning device can be thread speeds of 300 m / min and more and thus achieve high productivity. A increased yarn strength and thus an increase in value of the finished Yarn is also possible.
  • For printing the from the Compressed air source supplied compressed air can be a low value to get voted. Given the large number of spinning positions modern spinning machine leads to low air pressure considerable cost reductions in yarn production.
  • the fiber guide elements advantageously follow in Direction of fiber flow directly onto the sliver channel and are seen in the middle of the width of the sliver channel arranged along the long sides of the sliver channel.
  • the one Sliver facing inner surfaces of the fiber guide elements run in the fiber flow direction or in the direction of respective free end of the fiber guide elements on the Center of the sliver and have the smallest distance from each other at their free ends, thereby introducing facilitates and the guidance of the continuous sliver is improved.
  • the fiber guide elements are preferably so elastic trained that with an increase in through the sliver applied to the inner surfaces of the fiber guide elements Pressure can be deflected across the extension.
  • the fiber guide elements preferably run with their free, ends pointing in the direction of movement of the sliver flow towards each other and have the smallest distance from each other their free ends without touching each other.
  • the Fiber guide elements are advantageously designed so that you Cross section increases towards the free ends. It can Core fiber bundle centered on the imaginary axis of the Device run and the imaginary center line of the Sliver and the axis of the device coincide. By such training becomes the introduction and the run of the sliver and the leadership of the continuous sliver improved.
  • the position of the fiber guide elements is preferably adjustable and can be chosen according to the respective requirements become.
  • the distance between the free Ends of the fiber guide elements and the entrance opening of the Spindle 0.2 mm to 0.7 mm. This will make a targeted Control both in the effect and in the area of effect possible in a particularly simple manner. With such training and changing the position of the fiber guide elements can Thread formation can be influenced and varied advantageously.

  • From the inlet side of the Housing 2 leads a sliver channel 11 along the Center line 9 in the middle through the disk 3. From the sliver channel 11 there is a transition through an expanding conical Section into an initially cylindrical and then yourself also tapered area within the Nozzle device 7 and the receiving body 5.
  • the Fiber guide elements 16 formed fiber guide attached, the Fiber guide elements 16 obliquely inwards
  • the direction of fiber movement is inclined towards the center line 9 run.
  • the air chamber 17 is over to the outside a bore 18 with one for the sake of simplicity shown air source and inward through further holes 19 connected to an annular air duct 20.
