Definitions

  • the present invention relates to an apparatus for continuous ringless spinning of textile fibers by means of a rotating spinning chamber in which underpressure is maintained and in which separated fibers fed onto the inner surface of the peripheral wall of the spinning chamber slip along this inner surface onto an annular collecting surface at which the fibers collect in form of a ribbon to be spun in a known manner into a yarn which is withdrawn from the interior of the spinning chamber.
  • the spinning apparatus for continuous ringless spinning of textile fibers mainly comprises a spinning chamber rotatable about its axis and having an annular collecting surface on which separated fibers fed into the spinning chamber are adapted to collect under the influence of centrifugal forces to be spun into a yarn and a peripheral wall having an inner slip surface which is in the form of a surface of revolution having in axial crosssection the form of a curve, the tangents to successive points of which include, with a plane normal to the axis of rotation of the spinning chamber, angles which gradually decrease from a point most distant from the collecting surface toward a point closest thereto, means for supporting the spinning chamber rotatable about its axis, means for creating an underpressure in the spinning chamber, means for feeding separated fibers against the forementioned slip surface, and means for withdrawing spun yarn from the collecting surface.
  • FIG. 1 is a schematic axial cross-section of the ringless spinning apparatus according to the present invention.
  • FIG. 2 is a partial axial cross-section of .the spinning apparatus shown in FIG. 1, drawn to an enlarged scale, and showing the tangents to successive points of the slip surface.
  • the apparatus according to the present invention for continuous ringless spinning of textile fibers mainly comprises a spinning chamber I mounted for rotation about its axis on a shaft 2, which is journalled in anti-friction bearings 3 and 3a.
  • the bearings 3 and 3a are in turn mounted axially spaced from each other on the frame 5 of the apparatus, only partially shown in FIG. 1, and a pulley 4 fixed to the shaft 2 intermediate the bearings 3 and 3a serves to transmit a drive from a drive motor, not shown, to the shaft 2 for rotating the latter and the spinning chamber 1 connected thereto about the axis of the shaft 2.
  • the spinning chamber 1 is provided with a plurality of air escape bores 6 extending in substantially radial direction outwardly from a central cavity 1 in the bottom wall of the spinning chamber to create during fast rotation of the spinning chamber about its axis an underpressure in the interior of the spinning chamber.
  • Separated fibers 7 are fed from a separating mechanism 8a, of any construction well known in the art, through a curved passage 8 onto the inner surface 9 of the peripheral wall of the spinning chamber and the fibers 7 slide under the influence of centrifugal force along the inner surface 9 onto a collecting surface 10 at the lower end of the surface 9, whereby the fibers are simultaneously straightened, at the collecting surface 10 the fibers collect in form of a ribbon 7a which is spun in a known manner into a yarn 11, and the latter is withdrawn through the withdrawing funnel 12 out of the spinning chamber 1 by means of withdrawing rollers 13 rotating in opposite directions and engaging the yarn at opposite sides thereof, and subsequently the yarn 11 is wound on a bobbin 15 by means of a transverse roller 14.
  • Checking means for checking the presence of yarn may also be provided, but such checking means are not shown in the drawing, nor described in detail, since they do not form part of the present invention.
  • the slip surface 9 onto which the separated fibers are fed by the separating mechanism 8a and along which the fibers slide down onto the collecting surface 10 is a surface of revolution, coaxial with the axis of the spinning chamber 1, and having in axial cross-section the form of a curve the tangents t t to successive points P P P include with a plane 2 normal to the axis of rotation of the spinning chamber angles A A A which gradually decrease from the point P most distant from the collecting surface to a point P closest to the latter, as best shown in FIG. 2.
  • the collecting surface 10 itself is preferably an annular surface having in axial cross-section a substantially semicircular contour blending into the lower end of the slip surface 9, and the upper surface of the bottom wall of the spinning chamber, which is substantially normal to the axis thereof.
  • Separated fibers 7 are fed from the separating mechanism 8a through the passage 8 into the interior of the spinning chamber 1. Due to the rotation of the spinning chamber about its axis, and under the simultaneous action of the underpressure therein, the separated fibers 7 are projected against the slip surface 9 and owing to the advantageous shape of the latter, the fibers are accelerated and simultaneously straightened as they slide onto the collecting surface 10, where the fibers are collected in a ribbon 7a which is rolled up onto itself into a yarn 11, which is subsequently continuously withdrawn through the funnel 12 and wound onto the bobbin in the manner as described above.
  • An apparatus for continuous ringless spinning of textile fibers comprising a spinning chamber rotatable about its axis, said spinning chamber having an annular collecting surface on which separated fibers fed into the spinning chamber are adapted to collect under the influence of centrifugal forces to be spun into a yarn, and a peripheral wall having an inner slip surface, said slip surface being a surface of revolution having in axial cross-section the form of a curve, the tangents to successive points of which include, with a plane normal to the axis of rotation of the spinning chamber, angles which gradually decrease from a point most distant from the collecting surface to a point closest to the latter; means for supporting said spinning chamber rotatably about its axis; means for creating an underpressure in said spinning chamber; means for feeding separated fibers against a region of said slip surface distant from said collecting surface; and means for withdrawing spun yarn from said collecting surface out of the interior of the spinning chamber.
  • said means for creating underpressure in said spinning chamber comprise a plurality of substantially radially extending bores through a wall portion of said spinning chamber below said collecting surface.
  • said spinning chamber has a bottom wall formed with a central depression, said bores communicating at the inner ends thereof with said depression and leading from said depression to the outer surface of said spinning chamber.
