Definitions

  • the invention relates to a spindle for producing a yarn or twine with the features from the preamble of claims 1 and 5.
  • the task of introducing a flowable medium into the space delimited by the thread balloon without problems is achieved by the spindle rotor having a plurality of guide vanes arranged in the form of a spoke, the thread guide channel running through one of these guide blades.
  • the flowable medium is introduced into a rotationally symmetrical housing which is arranged between the spindle bank and the spindle rotor and is open at the top, from which it flows between the guide vanes of the Spindle rotor flows through and through the perforated protective pot bottom into the interior of the protective pot.
  • This housing takes up a lot of space and increases the overall height of the spindle due to its arrangement between the spindle bench and spindle rotor.
  • the guide blades of the spindle rotor have proven to be a hindrance to the free flow, in particular of solid particles, and ambient air is additionally conveyed through the spindle rotor as a result of the ventilation effect, which can lead to dirt deposits on the guide blades, which causes further undesirable effects on the entry of the medium can.
  • the invention has for its object to provide a spindle with the features specified in the preamble of claims 1 and 5 so that the device for introducing the flowable medium in the axial direction in the space delimited by the thread balloon little additional space, especially with regard to the height stresses the spindle and ensures trouble-free introduction of the medium.
  • the introduction of a fluid medium in the axial direction in the limited by the thread balloon Space is basically possible from two directions, namely either from above or from below.
  • the solution according to the invention comprises both options.
  • the medium When feeding from below, the medium is guided through the axis of the spindle rotor, which has the advantage that the medium can be fed from a point below the spindle bank and the height of the spindle above the spindle bank is not significantly increased as a result.
  • this embodiment variant is also suitable, for example, for retrofitting existing systems.
  • the flowable medium can be, for example, a treatment medium, such as conditioned air, but also multiphase media such as air and drops of suitable liquids, solid particles or dissolved fiber material suspended therein, which are said to have special effects on the thread or yarn.

  • the flowable medium M4 is again fed through the spindle rotor 35 via a line 33 which is passed coaxially along its entire length, the lower line section 33.1 of which, in a manner not shown, the medium M4 is supplied from a point below the spindle bank and whose upper line section 33.2 is guided via a pivot bearing 36 through the bottom 39.1 of the coil carrier with protective pot 39 into the interior of the coil carrier with protective pot 39.
  • the upper end 34.1 of the thread guide tube 34 also runs coaxially to the spindle axis A, while the adjoining lower end of the thread guide tube 34 forms the radial thread guide channel 34.2, from which the thread F6 emerges and through the thread balloon the centering point Z, which through a Thread guide eye 38 is formed, is supplied.
  • the delivery spool S4 is attached to the upper part 29.2 of the bobbin with protective pot 39 via a suspension device 37.
