Definitions

  • the present invention relates to a device for feeding into a spinning chamber fibers removed from a sliver when spinning staple fibers in a ringless manner, said device comprising a rotatable below atmospheric pressure spinning turbine and a carding device.
  • an object of the present invention to provide a device which during a spinning of staple fibers in a ringless manner will feed into a spinning chamber fibers removed from a sliver while overcoming the above mentioned drawbacks and which will make it possible to feed the fibers only to the front portion of the inlet part and then to convey the fibers to the spinning turbine.
  • FIG. 1 shows the principle of theprior art arrangement.
  • FIG. 2 shows the improved feeding system according tovthe invention.
  • FIG. 2a represents a portion of a modified centrifugal disc-opening-up roller combination according to the present invention.
  • the device according to the invention is characterized primarily in that a needle-free centrifugal disc has itsouter periphery shaped so, preferably conically or concavelyarc-shaped, that it will direct and convey the fibers onto an adjacent portion of the turbine inlet wall along which the fibers will then slide into a fiber collecting trough.
  • This centrifugal disc which rotates together with the opening-up roller may be arranged exchangeablyon the opening-up roller, but if desired, may also consist of one piece therewith.
  • FIG. 1 According to this known device, when spinning fiber slubbing in a ring-free manner with the opening-up roller 7 coaxially arranged with regard to the under atmospheric pressure spinning turbine 2, the opened-up fibers are, through an annular passage 4, conveyed over a sector (sektoral) to the inlet part 1 of the spinning turbine 2. After leaving the annular passage 4 and after being caught by the inlet'part 1 of the spinning turbine 2, the fibers are accelerated and conveyed into a fibercollecting trough 11. The said fiber collecting trough 1 1 must be kept at a sufficiently great distance with regard to the feed-in zone of fibers in conformity with the fiber length.
  • FIG. 2 An improved fiber feeding according to the present invention is shown in FIG. 2.
  • a needle-free centrifugal disc 12 which extends in substantially radial direction with a concavely arc-shaped periphery is so arranged at the end of the mantle of the conical opening-up roller 7 that the disc 12 either together with the opening-up roller forms a single unitary part (FIG. 2a), or in the form of a separate disc is arranged on the mantle of the opening-up roller (FIG. 2).
  • This centrifugal disc 12 is intended to cover up the zone of the fiber infeed 13 with regard to the zone of the yarn withdrawal 10 to a greater extent.
  • the centrifugal disc 12 is intended to feed the fiber infeed 13 to the spinning turbine 2 only at the front portion of the inlet part 1, which front portion may have a length of from 10 to 30 millimeters and preferably has an inclination of from 10 to 40 with regard to the fiber collecting trough 11. From this zone 13, the fibers coming from the opening-up roller 7 will, after having been grasped by friction by the inlet part 1 of the lower thanatmospheric pressure spinning turbine 2, slide along the conical inlet part 1 of the spinning turbine 2 into the fiber collecting trough l I. From here the said fibers are in the form of spun yarn 8 withdrawn to the center of the turbine 2.
  • the spacing between the outer diameter of the centrifugal disc 12 and the spinning turbine inlet part 1 is adjusted by a non-illustrated adjusting device so that the fibers can unimpededly reach the fiber collecting trough ll of the spinning turbine 2.
  • the diameter of the centrifugal disc 12 must be so selected that an opening of the spinning chamber for purposes of cleaning the same or remedying a thread break will still be possible by folding over or withdrawing the spinning turbine 2 together with its housing.
  • an apparatus which includes: a rotatable spinning turbine having an inlet wall portion, rotatable opening-up roller means for withdrawing fibers from a sliver, and centrifugal disc means connected to said roller means for rotation therewith, said roller means and said disc means being arranged adjacent said inlet wall portion, and the outer periphery of said disc means facing toward said inlet wall portion for directing fibers withdrawn by said roller means onto said inlet wall portion.
  • said spinning turbine has fiber collecting trough means at one end of said inlet wall portion, and in which the extension of said inlet wall portion from that end thereof which is remote from said fiber collecting trough means in the direction toward said trough means by a distance within the range of from 10 millimeters or 30 millimeters represents substantially the only area upon which the fibers are directed by said disc means and from where they slide into said trough means.
