Definitions

  • the machine for spinning textile fibres has a rotor in the form of a multi-vane wheel including a disc having a central opening and a fibre-supporting surface adapted to receive a stream of fibres thereupon and which takes part in formation of a yarn from these fibres at rotation of the rotor, the yarn being withdrawn through the central opening.
  • a plurality of slots is made through this disc surface, extending from the central opening toward the periphery of the disc, projections being located on this fibre-supporting surface intermediate of these slots, in order to assist in retaining the fibres at this surface of the disc.
  • the machine provides for reliable retention of the fibres at the supporting surface of the disc irrespective of the angular speed of rotation of the rotor; furthermore, it effects the removal of foreign matter directly during the course of spinning without affecting this process.
  • the proposed machine may be employed with the utmost effectiveness for spinning yarn having a high linear density.
  • the invention may be employed with the utmost effectiveness in the production of reinforced or braided yarn, as well as for yarn featuring a greater linear density than those commonly attainable in yarn produced by known ring spinning machines.
  • reinforced or braided yarn denotes yarn having a central core with a braiding about this core, and with the core being made of a material having a greater strength than that of the braiding fibre.
  • linear density is to be understood as a ratio of the weight of the yarn with respect to the length thereof, i.e. the weight of a linear unit of the yarn, which is a value directly related to the yarn thickness.
  • machines for ringless spinning of textile fibres which comprise a feeding device including a passage through which a stream of fibres may be fed and a rotor mounted on a spindle by means of a sleeve, with the rotor including a multi-vane wheel adapted to create a stream of air with the rotation so as to effect the conveying of the fibres.
  • the multi-vane wheel includes a disc with a support surface adapted to receive thereupon the fibres being conveyed in order to form a yarn of these fibres with the rotation of the rotor, with the yarn being withdrawn by a pair of rollers through a central opening provided in this surface.
  • the above situation may be improved by providing mechanical forces to act on the fibres and thus helping to retain the fibres on the supporting surface.
  • the known machines are devoid of means capable of providing such mechanical forces.
  • the present invention is aimed at providing a machine for ringless spinning of textile fibres, which would be capable of reducing the degree of spraying of the fibres and which would provide for the production of a yarn having the desired linear density at increased rotor rotation speeds, due to the incorporation therein of auxiliary means adapted to create mechanical forces acting on the fibres and simultaneously retaining these fibres at the surface of the disc.
  • a machine for ringless spinning of textile fibres comprising a feeding device including a passage adapted to have fibres fed therethrough and a rotor mounted on a spindle by means of a sleeve, with the rotor being in the form of a multi-vane wheel adapted to create upon the rotation of this rotor, an air stream for conveying with the fibres, the rotor including a disc having a supporting surface adapted to receive thereupon the fibres being conveyed and which forms a yarn from these fibres upon the rotation of the rotor, with the surface having therein a central opening through which said yarn is withdrawn in operation, in which machine, in accordance with the invention, the disc has a plurality of slots made therethrough spaced from the central opening and extending in a direction away from this opening to the periphery of the disc, with there being provided between each pair of each adjacent slots at least one projection adapted so as to retain the fibres at the supporting surface of the disc upon rotation thereof, and
  • the projections serve as guarding means on the supporting surface of the disc, assisting in retaining and concentrating the main stream of the fibres at the central portion of the disc, which makes it possible to carry out the spinning process at elevated rotor rotation speeds. This has become possible due to the fact that, although at these elevated speeds the increased centrifugal forces tend to throw the fibres off the disc, the projections induce a mechanical action on the fibres so as to counteract this tendency.
  • the provision of the slots through the disc draws air through these slots, which creates an additional biasing effect upon the fibres tending them toward the surface of the disc and also biasing any foreign matter traveling with the fibres to this disc, with this foreign matter being subsequently removed from the surface of the disc by the action of the centrifugal forces.
  • the through slots should extend to the edge of the disc, thus dividing the disc into segments, with each such segment having at least one of said projections situated thereon.
  • slots should extend radially and be evenly spaced over the surface of the disc.
  • the slots may be expedient for the slots to be arranged in a fan-like fashion and shaped as arcs of the same radius.
  • each pair of through slots defining the segment therebetween is arranged so that one of these slots extends parallel to one of the axes of symmetry of the disc, whereas the other one is inclined at a specified angle relative to this axis.
  • the rotor has a disc wherein the radial slots are uniformly spaced about the surface of the disc.
  • the segments of the disc be connected with the vanes of the wheel and the sleeve of the rotor so that a space for the removal of foreign matter be formed between the disc and the face end of the sleeve facing this disc.
  • each of the projections is shaped as either a rectangle, or a triangle, or a trapezium in cross section; whichever the shape, it is expedient that the apex of the projection be rounded.

  • the disc 9 has a plurality of slots 14 (FIG. 3) made therethrough, the slots 14 being at a certain distance from the central opening 13 and extending away from this opening toward the periphery of the disc, the slots being intended to have the air drawn therethrough, together with any foreign matter being separated from the fibres, as the latter are formed into the yarn.
  • the fibresupporting surface 10 of the disc 9 has a projection 15 made thereon, with all these projections 15 being uniformly spaced from the axis of rotation of the disc 9 and assisting in retaining the fibres at the fibresupporting surface 10 of this disc 9.
  • the latter may extend to the edge 16 (FIG. 4) of the disc 9, i.e. the slots may be open at this edge, in which case the slots 14 divide the disc 9 into segment 17, with each such segment having thereon a projection 15.
  • each such segment 17 is connected to the respective vane of the wheel 8 and the sleeve 5 so that a space 19 (FIG. 5) is defined between the disc 9 and the face end 18 of the sleeve 5, facing the disc 9.
  • the through slots 14 extend radially and are uniformly and angularly spaced about the surface of the disc, as is shown in FIGS. 6 and 7.
  • each segment 17 has two projections 15 (FIG. 7) defining therebetween a clearance through which the air is additionally drawn from the central portion of the disc 9.
  • the slots 14 extend from the central opening 10 in a fan-like fashion and are shaped as arcs of the same diameter. On each segment 17 defined by these arcuate slots 14 a projection 15 is situated.
  • pairs of through slots defining segments 17 therebetween are arranged so that one of the two slots (the slot 20) is parallel to one of the axes 21 and 22 of symmetry of the disc 9, whereas the other slot 23 is inclined relative to said axis at an angle a.
  • the projections 15 may have various crosssectional shapes.
  • the projections 15 should be shaped in its cross-section as triangles, or as rectangles, or as trapazoids (FIGS. 10c, 10b and 10e, respectively).
  • the projections 15 may be shaped in cross-section as right-angle triangles (FIG. 10a).
  • the projections 15 may be shaped in cross-section as acute triangles with the apex being inclined relative to the axis of rotation of the disc (FIG. 10]).
  • the portion of the surface 10 thereof, defined by the projections 15, may have perforations 24 (FIGS. 11 and 12) made therethrough.
