Cl. 57/56 57/58 89 ended Spinning rotor removing Yam the 51 Int. Cl Dim.
  • the present invention relates to the spinning of yarns from textile fibres, and more particularly to the open end spinning of yarns.
  • textile fibres are conveyed in an airstream through a fibre feed duct into a spinning rotor to collect on an internal fibre collecting surface of the rotor from which they are picked up by a tail end of a yarn which is continuously formed thereby and which is withdrawn from the rotor through a yarn delivery duct.
  • the rotor is open at one end and adjacent this open end is a stationary closure member.
  • the rotor is contained in a chamber and airstream is created in the fibre feed duct for feeding fibres either by subjecting the chamber to suction which causes air to exhaust from the chamber through a port in the chamber wall or by providing apertures in the rotor wall.
  • An object of the invention is to provide a method of and apparatus for the open-end spinning of textile yarns in which the aforementioned disadvantages associated with debris deposition within the rotor are reduced.
  • a method of open-end spinning textile yarns comprising feeding fibres to an internal fibre collecting surface of a spinning rotor, removing spun yarn from said spinning rotor through a yarn delivery duct, and passing air continuously through the interior of the spinning rotor by means of anair passage extending through a cover member adjacent an open end of the rotor, whereby to remove debris from the interior of the rotor during the spinning operation.
  • apparatus for the open-end spinning of textile yarns comprising a spinning rotor which is open at one end and which is provided with an internal fibre collecting surface, a cover member adjacent said open end of the rotor, a fibre feed duct through which, in use, fibres are conveyed to said fibre collecting surface, a yarn delivery duct through which, in use, spun yarn is removed from the spinning rotor, and an air passage extending through the cover and so arranged to pass air continuously through the interior of the spinning rotor during the spinning operation that debris is removed from the interior of the spinning rotor by said air.
  • FIG. 1 is a cross-section through a spinning assembly according to a first embodiment of the invention
  • FIG. 2 is a cross-section through a spinning assembly according to a second embodiment of the invention.
  • a chamber 1 is closed by a closure member 2 which has a cylindrical depending portion 3 terminating within the open end of a spinning rotor 4 arranged for rotation within the chamber 1.
  • the spinning rotor 4 is mounted on a drive shaft 5 suitably connected to drive means (not shown).
  • the spinning rotor 4 has an upstanding wall 6 which converges slightly towards the open end of the rotor 4 and a fibre collecting groove 7 at the region of maximum internal diameter where the wall 6 meets the base 21 of the rotor 4.
  • the internal surface of the rotor 4 is free from apertures.
  • a fibre feed duct 8 passes through the closure member and extends towards the wall 6 of the rotor 4.
  • a yarn delivery duct 9 also passes through the closure member 2, is co-axial with the axis of the spinning rotor 4 and terminates within the spinning rotor 4 in a frustocomically shaped flange 11 which forms a flared mouth 10 located below the level of the open end of the rotor 4.
  • the annular core member 13 is secured by screws one of which is shown at 19 which pass through the collar 18 and the closure member 2 into tapped holes provided in the core member 13.
  • the direction of the annular passage 16 is generally downwards and radially outwards with respect to the axis of the spinning rotor 4.
  • An air duct 17 communicates with the annular passage 16 and extends through the closure member 2.
  • the duct 17 and the yarn delivery duct 9 are held by a collar 18 positioned on the top surface of the closure member 2.
  • the interior of the chamber 1 is connected to suction means through a suction duct 20.
  • a suction pump connected to the suction duct 20 is actuated and evacuates the chamber 1 thus creating an airstream down the fibre conveying duct 8.
  • fibres are delivered by suitable opening means (not shown) and are conveyed in discrete manner by the airstream toward the rotating spinning rotor 4.
  • the fibres are collected in the fibre collecting roove 7 and are picked up and twisted into a tail end of spun yarn 26.
  • the spun yarn 26 is withdrawn through the yarn delivery duct 9 to be wound up in the usual manner.
  • air is also drawn into the rotor 4 through the air duct 17 and admitted into the rotor 4 through the annular passage 16.
  • the airstream as it emerges from the annular passage 16 is direcred generally radially outwards towards the wall 6 of the rotor.
  • the airstream leaves the interior of the rotor 4 through an annular gap 22 provided between the rotor rim 23 and the cylindrical depending portion 3 and is finally exhausted through the suction duct 20. It has been found that a large portion of the debris liberated from the fibres entering the spinning rotor 4 is entrained by this airstream and is carried to the suction duct 20.
  • FIG. 2 A second embodiment is illustrated in FIG. 2, parts common to the embodiments of FIGS. 1 and 2 being given the same reference numerals and not being described in detail.
  • suction is applied to the air duct 17 so that it draws air from the chamber 1 which has entered through fibre feed duct 8 and yarn delivery duct 9.
  • the suction duct 20 provided in the wall of the chamber l of the embodiment described with reference to FIG. 1 is dispensed with.
  • the debris liberated within the spinning rotor 4 is entrained in the air flow and is removed thereby from the chamber 1 through the air duct 17.
  • any debris which does become deposited in the fibre collecting groove 7 is held in the groove 7 by the centrifugal force exerted by the rotating rotor 4.
  • some of this debris is scooped up and entrained by the yarn 26 and is thus removed from the spinning groove 7 and is then passes, in the formed yarn 26, to the edge 24 of the yarn delivery duct 9 formed by the conically shaped flange 11. In passing over this edge 24 the entrained debris is scraped from the yarn 26.
  • the annular passage 16 opens within the rotor at a point immediately above the edge 24 of the yarn delivery duct 9 at the position where the debris is scraped from the outgoing yarn 26.
  • the debris liberated from the yarn 26 is entrained by the air entering the rotor 4 and carried out of the rotor 4 by the airstream to leave through the suction duct 20.
  • the debris liberated from the yarn 26 is entrained in the airstream leaving the rotor 4 through the annular channel 16 and is deposed of through the air duct 17.
