Definitions

  • lint forms in the spinning chamber when carding the slubbing composed of staple fibers into individual fibers.
  • the formation of lint is caused by the carding means rotating at a high speed and the withdrawing nozzle. Due to the prevailing flow conditions, this lint will collect or accumulate in'the fiber collecting trough of the spinning turbine and also in the inner contour of the carding means, from where it cannot be removed.
  • FIG. 1 shows a prior art arrangement of a spinning turbine with carding'means.
  • FIG. 3 illustrates a modification according to which the cover disc forms a stationary disc on the bearing pivot of the carding element.
  • the spinning turbine may be provided with radial and/or axial bores for the withdrawal of the centrifuged offlint orflue.
  • the radial bores are located in the inlet portion.
  • the axial bores are provided at the flange side adjacent the fiber collecting trough.
  • the prior art arrangement shown in FIG. 1 for avoiding the accumulation of lint in thespinning chamber when spinning slubbing in a ringless manner comprises primarily a subatmospheric pressure spinning turbine 2 and a carding device 1.
  • the device of FIG. 1 has been improved according to the present invention inasmuch as the inner contour 6 of the carding device 1 has been covered by a disc 7. Due to the covering up of the inner contour 6 of the carding device 1, a considerable portion of the air turbulence is transformed into a laminary flow. Since the bottom surface of the carding device 1 formed by the disc 7 and the inner contour 9 on the flange side of the spinning turbine 2 are to a great extent nearly parallel and have the same sense of rotation, for all practical purposes a laminary air flow is created between the two surfaces of rotation.
  • a spinning device for ringless spinning which includes a subatmospheric spinning turbine, a rotatable carding member arranged substantially coaxially with said spinning turbine and having an open side facing toward said turbine, and disc means closing said open side and having its outer surface substantially flush with that surface .portion of said carding member which defines said open side.
  • a device which includes means connected to and holding said disc means stationary with regard to said rotatable carding member.
  • a device in which said spinlecting trough means, and in which said peripheral ning turbine has fiber inlet means provided with radial flange means is provided with axial bores near said bores.
