Definitions

  • the present invention is based on the discovery of a novel device by which disintegrating of the sliver or rove and recombining the disintegrated fibre into a continuous yarn can be performed in an unexpectedly simple and efiective manner by the application of pneumatic forces coupled with dynamic forces capable of being produced by very simple machinery involving a minimum of moving parts.
  • Gbjects of this invention include the provision of a new device for producing spun yarn by the direct disintegration of sliver or rove and recombination of the disintegrated fibre into a continuous yarn of extremely satisfactory textile characteristics; the provision of such a method relying primarily on the effect of an airstream for shredding the fibre; the provision of such a method wherein the spun yarn grows by accretion at one end thereof through the pick-up of loose fibre spread over a surface in motion relative to said end; the provision of novel spinning apparatus of very simple and economical design, maintenance and operation, wherein the only moving part is a spinning rotor; and broadly the Provision of method and means for producing high-grade spun yarn in a more effective and generally satisfactory way than was heretofore possible.
  • the spinning system of the invention comprises feeding a sliver or rove of short fibre to a receiving surface while exposing the sliver to an airstream to shred the sliver and project the shredded fibre in an evenly spread layer upon said surface, displacing the tip of a yarn relative to said surface in contact engagement with the layer of fibre thereon and drawing said yarn away at a rate correlated with the rate of feed of the sliver to the surface,'whereby the tip of yarn will pick-up fibre from said layer and grow by accretion to form spun yarn as a continuous extension of the yarn initially provided.
  • a second airstream is discharged in opposition to the first airstream so as to create a neutral boundary layer at the meeting of both airstreams, and the airstreams are regulated relative to each other to position said boundary layer intermediate the sliver and the yarn so as to separate them effectively by purely pneumatic means.
  • the receiving surface is the peripheral wall surface of a cavity defined in a rotor, the rotation of which serves to draw in air axially through passages at both ends of the cavity to produce said airstreams and discharge them radially outward by centrifugal force, simultaneously projecting the shredded fibre by centrifugal force against the peripheral surface of the cavity.
  • FIG. 1 is a simplified view in axial section of spinning apparatus according to a first embodiment of the invention
  • FIG. 2 is a transverse cross section made on the line 11-11 of FIG. 1;
  • FIG. 3 is a view generally similar to FIG. 1 illustrating a modified embodiment
  • FIG. 4 is a section on the line IV1V of FIG. 3.
  • the spinning apparatus illustrated in FIGS. 1 and 2 comprises a conventional feeder device consisting of a pair of rolls 11 and 12 adapted to feed a rove or sliver It made up of short discontinuous textile fibres to a stationary inlet nozzle 2, thence into the inner cavity of a revolving rotor or turbine 3, whence the yarn issues through a stationary outlet nozzle 4 to a delivery device comprising a pair of rolls 5-6.
  • a conventional feeder device consisting of a pair of rolls 11 and 12 adapted to feed a rove or sliver It made up of short discontinuous textile fibres to a stationary inlet nozzle 2, thence into the inner cavity of a revolving rotor or turbine 3, whence the yarn issues through a stationary outlet nozzle 4 to a delivery device comprising a pair of rolls 5-6.
  • the entire system is shown in this embodiments as disposed vertically.
  • the input or feeder device comprising the pair of rolls 11, 12 may conveniently constitute the output or delivery rolls of a conventional roving apparatus delivering a continuous strip of short fibres, free of any twist (and constituting a sliver), or provided with a minimum amount of twist to impart some stiffness thereto (i.e. a rove).
  • This sliver or rove is then guided through the inlet nozzle 2 which is in the form of a simple cylindrical tube.
  • the turbine 3 comprises a rotor in the form of a generally fiat disk defining an inner cavity having its radially outer periphery bounded by an annular trough 14.
  • the rotor 3 is here shown as supported for rotation about the outlet nozzle 4, in alignment with the inlet nozzle, by means of spaced ball bearings 15 and 16 having their inner races secured to said outlet nozzle 4 and their outer races secured in a bore 17 of a hub or nose 18 projecting downwardly from lower wall 312 of the rotor.
  • the lower end portion of the hub 18 is defined by a pulley 19 for connection by way of a drive belt 21 with any suitable source of kinetic power.
  • the lower wall 312 of the rotor is formed with an annular series of holes 24 adjacent to the trough 14 but along a radius smaller than the maximum radius of said trough.
  • upper wall 3a is formed with an annular set of holes 25 positioned approximately on a circumference of equal radius to the series of holes 24.
  • the lower or outlet end of the inlet nozzle 2 extends through a hole 27 formed axially in the upper wall 3a of the rotor, with sufiicient clearance to avoid objectionable friction.
  • the inner wall surface of the trough 14 is arranged to facilitate slipping of the fibres thereover as will be more fully described later, and is advantageously for this purpose provided with a highly smooth surface finish. It should be noticed however that the important point in this respect is that the wall surface shall not oppose any resistance to the fibres in the circumferential direction.
  • the revolving rotor 3 functions as a two-way suction pump, with air being continuously drawn in axially both through the inlet nozzle 2 and the outlet nozzle 4 into the cavity of the rotor, and discharged by centrifugal force radially outwards across the cavity and out through the peripheral holes 25 and 24 respectively.
  • An annular series of radial blades 23 is shown provided in this embodiment adjacent the holes 24 to increase the rate of discharge of the air therethrough.
  • the sliver advances downwards through the nozzle 2 it is exposed to a violent shredding action from the air which is simultaneously being drawn at a high velocity down through said nozzle, so that at its entry into the cavity of the rotor 3, the fibre is in a loose, disintegrated state in suspension in the air entraining the same.
  • This mixture of air and shredded fibre entering the rotor cavity is subjected to the concurrent actions of centrifugal force and friction against the inner surface of the upper wall 3a.
  • Each air molecule is driven outward at alinear velocity that increases continuously from the center to the periphery of the rotor, with its angular velocity increasing concurrently from zero at its point of entry into the rotor to a maximum equal to the angular velocity of the rotor 3 itself as it strikes the surface of the peripheral trough 14.
  • the air molecules describe outwardly spiralling paths, and impart substantially identical spiral paths to the particles of textile fibre suspended in the airstrearn as indicated schematically by the discontinuous spiral lines in FIG. 2.
  • the shredded fibres stripped from the sliver It in the input nozzle 2 are introduced in the form of a spread-out shower into the upper part of the rotor cavity.
  • the spreading shower of shredded fibres entering into the upper chamber A and spiralling outwards therein along the upper wall 3a retain their general orientation throughout their spiral paths owing to the action of the expanding air medium in which they are entrained. That is, the head end of each fibre reaches the peripheral trough surface first, and as that surface is revolving at an angular velocity higher than the fibre end, the remaining length of the fibre is then forcibly applied against the trough surface, so that the fibres are laid down in an extended or stretched condition and with a regular circumferential orientation over'the bottom of the trough, i.e. along the maximum-diameter region thereof. In other words, all the fibres are lying more or less straight and taut rather than any of the same tending to curl or loop.
  • the angular velocity of the outer end of the yarn 3% assumes a value W2 somewhat higher than W1, and the precise value is determined by the draft velocity imparted to the yarn by the output rolls 5-6.
  • the outer end of the yarn 30 sweeps around the periphery of trough 14 at a relative velocity (w2w1), so that it continually sweeps and picks up the incoming fibre progressively as the latter are deposited around the trough wall, and the yarn thus grows continually by accretion.
  • the loose incoming fibre entering the upper part A of the rotor cavity are maintained positively isolated from the yarn 30 in process of formation in the lower space E of said cavity, by the non-material partition constituted by the flat neutral zone or boundary layer P at which the rising and descending airstreams meet.
  • the rotor 3 In order to prime the apparatus at the start of a spinning run, the rotor 3 is set into rotation and an input sliver is fed into its cavity by means of the input rolls ll, 12 and input nozzle 2, until a layer of shredded fibre has been deposited around the surface of trough 14 in the manner described above. A previously formed yarn 3a?
  • the thickness of the resulting spun yarn depends essentially only on the relation between the input feed rate of I the sliver and the yarn output rate imparted by the delivery rolls 5-6, assuming a correct angular rate is imparted to the rotor 3. It will readily be understood that the higher the ratio of input to output feed rate, the thicker the spun yarn obtained. Conversely, if the output feed rate is increased in relation to the input feed rate, the yarn delivered at the output of the device will be increasingly thin, and should the relative increase in output rate be continued beyond a certain point, the apparatus will be unprimed.
  • the input feed rolls 11, 12 may be considered as the input rolls of a yarn drawing system, wherein the draft rolls are replaced by the suction applied to the fibre in the input nozzle 2 of the turbine.
  • the whole length of each fibre should at that point have moved past the pinch point or nip of the input rolls.
  • the distance from said nip to the entrance of the rotor cavity should be somewhat longer than the maximum length of the fibre encountered in the sliver or rove to be processed.
  • the diameter of the input and output nozzles 2 and 4 in relation to the length thereof should be so determined that the loss of air pressure occurring therethrough or flow resistance opposed thereby to the respective airstreams, shall substantially balance each other, so that the neutral zone P in which the two airstreams op pose each other and provide the non-material partition etween the rotor cavity chambers, will be properly positioned substantially on the central transverse plane of the rotor cavity.
  • the axial length of the rotor cavity of the turbine 3 should be large enough to provide sufiicient depth in each of the chambers A and B for the necessary motion of the fibres therein and also to ensure that the position of the neutral partition zone P separating said chambers will not be too critical in view of the considerations of aerodynamic balancing stated in the foregoing paragraph.
  • an upper limit to said axial length is set by the condition that the airstrearns should not be subjected to a reduction in velocity so great as to prevent the setting up of a stable boundary layer P capable of acting as an effective partition between the two chambers.
  • the lower wall of rotor 49 is formed with an annular recess 42 near its outer periphery, the radially outer surface of this recess being provided as a frustoconical surface 43 of inverse, taper from that of the surface 41.
  • the dimensioning is such that horizontal segment 44 of yarn 45 in process of formation bridges the annular recess 42 and engages the outer wall surface of the rotor cavity substantially at the base of the upwardly tapering surface 41.
  • the direction of fibre pick-up by the tip of the yarn being spun is indicated by the arrow M which corresponds tothe sense of relative rotation of the yarn with respect to the rotor and fibre. Itis noted that the direction of twist imparted to the spun yarn, as indicated by the arrow f3 in FIG. 4, is the sarne as in the case of the first embodiment.
