  • the accumulation of electrostatic charges on elements of the machine and on strands being formed thereby is reduced, so as to facilitate formation of yarns by the textile machine.
  • the repeated and periodic direction of an electrically charged flowing stream of air toward the machine is preferably accomplished through the provision of a traveling pneumatic cleaner means and electrical charging means mounted thereon for electrically charging an air stream delivered by the traveling pneumatic cleaner means.

  • drive means and a fan are provided for inducing air in the spinning room to flow through the cleaner means for pneumatic cleaning.
  • traveling pneumatic cleaner means 20 may be arranged to traverse a plurality of textile machines such as a spinning frame 10, the present invention contemplates also that the traveling pneumatic cleaner means 20 or the manner in which the cleaner is supported and arranged for traversing a textile machine may be changed in varying ways, including limiting the path of travel of the cleaner to traversal of the single machine only.
  • the traveling pneumatic cleaner means 20 travels a flowing stream of air along a textile strand forming machine such as a spinning frame 10 and sequentially directs the air stream toward individual strand forming stations in a series spaced therealong and toward the strands being formed at the stations.
  • conventional ring spinning frames in wide use in the textile industry of the world at the present time include a creel portion wherein a plurality of bobbins of roving R are suspended, drafting systems D to which the roving is supplied, and spindles on which bobbins of spun yarn Y are wound.

  • electrostatic charges are generated at each of the series of strand forming stations spaced along the frame 10, as defined by the spinning rings 1 l and associated spindles.
  • advantage is taken of the traversal of the spinning frame 10 by the traveling pneumatic cleaner means for reducing accumulation of electrostatic charges produced in forming the yarns Y at the strand forming stations along the frame 10.
  • movement of the traveling pneumatic cleaner means 20 relative to the frame 10 travels a flowing stream of air along the textile strand forming machine while sequentially directing the air stream toward the individual strand forming stations and toward strands being formed at the stations.
  • This broad function of the traveling pneumatic cleaner means 20 is as set forth in aforementioned U.S. Pat. No. 3,304,571.
  • the air stream delivered by the traveling pneumatic cleaner means 20 is electrically charged, such as by delivery of the air through an electrical charging means generally indicated at 30 which ionizes at least a portion of the air flowing in the stream through a trailing blowing sleeve 22 and emitted from the traveling pneumatic cleaner means 20.
  • the electrical charging means 30 comprises a conduit section 31 (FIGS. 2 and 3) preferably defined by a metallic tube and having a plurality of openings 32 therethrough.
  • the openings 32 preferably are circular in character and are arranged around the circumference of the conduit section 31 in a generally circular pattern.
  • Surrounding the openings 32 is a mounting ring 34 hearing therewithin a plurality of pointed electrode members 35.
  • the electrode members 35 are electrically insulated from the conduit section 31.
  • the conduit section 31 and the electrode members 35 are electrically connected with a high voltage generator 39.
  • the high voltage generator 39 generates a relatively high voltage alternating current, but supplies such current at a relatively low amperage.
  • suitable transformer means may be incorporated in the high voltage generator 39 and power therefor may be drawn from the electrical power source from which current is obtained for the traveling pneumatic cleaner means 20.
  • ionized or electrically charged air is delivered by the traveling pneumatic cleaner 10 to those portions of the spinning frame where the yarns Y are being formed.
  • the ionized air gives up or takes on electrons in such a manner as to reduce electrostatic charges otherwise found on the frame 10 and the yarn Y.
  • reduction or neutralization of the electrostatic charges spinnability of the textile materials being formed into the yarns Y is promoted and a more consistent yarn is produced.
  • FIG. 1 certain alternative arrangements for an electrical charging means are illustrated in connection with a leading blowing sleeve 22, which will be noted as incorporating electrical charging means 30 mounted at a location nearer to air discharge nozzles 25 through which air is emitted from the sleeve 22.
  • a drafting system air discharge nozzle 26 is particularly illustrated as having an electrical charging means 30 mounted immediately adjacent thereto. While not specifically illustrated herein, the present invention contemplates that such cooperation of electrical charging means with blowing air means may be independent of the incorporation of cleaning functions and electrostatic reducing apparatus as herein disclosed may operate independently of but on a common track with traveling pneumatic cleaner means.
  • the ionized air delivered by the traveling pneumatic cleaner 10 be able to accommodate electrostatic charges of either positive or negative polarity.
  • This is preferred due to the observed fact that the polarity of electrostatic charges on a spinning frame 10 varies from time to time and may quickly reverse from one polarity to the other. Accordingly, it is desirable to accommodate any such reversal of polarity as may occur.
  • the use of an alternating current high voltage generator is of particular assistance in achieving this end, in that ions of both negative and positive polarity are generated thereby.
  • direct current voltage generators may be employed with the structure illustrated in the drawing, to produce ions of a single polarity. While such production of single polarity ions is effective to neutralize electrostatic charges of one polarity when encountered, it will be understood that production only of a single polarity of ions may, under some circumstances, limit the range of usefulness of such a combination.
  • control means may be provided for sensing the polarity of electrostatic charges found on a traversed spinning frame 10, with cooperating control means switching the polarity of ions produced in accordance with the sensed electrostatic charges. Further, it is contemplated that appropriate control means may respond to variations in the magnitude of electrostatic charges sensed to be present on a spinning frame 10 by varying the relative quantities of ions produced.
  • the present invention has been illustrated with particular reference to one form of electrical charging means for air being delivered by the traveling pneumatic cleaner means 20 (as illustrated in FIGS. 2 and 3), the present invention contemplates that electrically charged or ionized air may be produced through the use of other means.
  • the relative persistency of ionized air around the spinning frame 10 may depend in part upon the relative concentration of ions in the volume of air ambient to the spinning frame 10, the relative volume of ions present in air delivered from the traveling pneumatic cleaner means 20, and the velocities of the air.
