Definitions

  • the present invention relates to a process for pneumatically parting fiber flocks, and to the manner of carrying out this process, more especially for the continuous conventional manufacture of unwoven felts of textile webs.
  • this fibreseparating system being, a mechanical system, cannot give complete satisfaction 'by reason of the breakages of the fibres, by reason of being poorly adapted to the working of very short fibres, by reason of the limitation of the tangential speed of beaters equipped with pins or teeth which hardly permits of increasing the production of unwoven fleeces, the quality of which moreover depends upon good distribution of the fibres, perfect regularity of which these machines cannot ensure, and their coating with synthetic binders, whether liquid or in dry powder form, which is a function of the degree of separation of the fibres.
  • the present invention proposes to replace the second group of mechanical elements by a pneumatic device for tearing into fibres with regulable pressure which is particularly adapted to the work of opening up flocks of any origins, without distinction of fineness, flexibility of fibre length, which can be of one single kind or short or can be mixed.
  • variable pressure of the. air jets permits higher jet speeds than the tangential speeds of rotatable mechanical elements.
  • FIGURE 1 is a side elevation of the pneumatic device for opening up or parting of fibres, mounted at the end of a feed table;
  • FIG. 2 is a similar view, the supply of the fibre flocks being effected by an Archimedean screw;
  • FIG. 3 is a similar view, flocks being taken between two fluted cylinders
  • FIG. 4 is a similar view, more especially for long fibres.
  • FIG. 5 is a side elevation of the entire assembly for the continuous manufacture of unwoven fleeces or felts which can comprise one of the systems for pneumatic opening of the fibres according to FIGS. 1, 2, 3 or 4.
  • the opening up of flocks of textile fibres and their separation are effected progressively by means of a pneumatic system replacing the conventional mechanical elements for tearing apart, having lateral or rotating movement, in which pneumatic system air jets act upon the flocks, the controllable air pressure being intro- 3 quizged into the flocks, to cause the fibres to fly individually as they are liberated from the retention of the supply device.
  • the pneumatic system comprises two parallel, juxtaposed and staggered air jets, acting vertically one against the other, which act upon the cushion of fibre flock 2 sliding over the fixed feed table 3 and delivered by the regulable-pressure fluted feed cylinder 1.
  • the flock is presented to a first pneumatic jet 4 which projects the liberated fibers downwards where they encounter the jet 5 which drives them upwards again.
  • the feed table 3 is of a special form. Its nose 3' is of concave, in-curved form in order to lay out the flock delivered by the cylinder 1 of the table 3 under the action of the jet 4 in the form of a tuft. This curvature has the purpose of deviating the jet 4 with the fibres which it detaches from the tuft on to the jet 5, which completes the opening up of the flock not yet opened and torn into fibres by the jet 4.
  • the spacings 6 and 6 of the jets are adjustable by any conventional means.
  • FIG. '2 when the flock is supplied by an Archimedean screw 7 within a tube 8, a nozzle 9 projects a jet of air under a pressure of 7 to 6 kg. violently on to the flock of fibres presented at the exit of the tube 8 at 10.
  • a second jet of air under pressure issues from the tube 8 through the end piece 11 by way of the aperture 12 of an adjustable section. This second air jet, with adjustable pressure and delivery quantity, liberated at 12, projects the opened fibres forward as they are supplied by the screw 7.
  • FIG. 3 the flock 2 supplied by the conveyor belt 13 beneath the equalising cylinder 14 is taken between the two feed cylinders 15 and 16, the upper cylinder being adjustable in pressure upon the lower cylinder.
  • These two cylinders form the point of retention of the fibre flock which is opened out at the exit therefrom by the air jet issuing from the adjustable nozzle 17.
  • the fibres thus separated under the action of the air jet fly ofl and are directed towards elements which subject the fibres to further treatment.
  • FIG. 4 shows another form of embodiment intended more especially for the pneumatic opening up of long fibres of 60 to 100 mm. mixed according to the need with short fibres of irregular lengths of from 5 to 50 mm.
  • the flock of fibres 2 passing beneath the equalising cylinder 14 is brought by the conveyor belt 13 on to the feed table 3 having a concave, in-curved nose 3, and beneath the fluted feed cylinder 1 of regulable pressure, which feeds it and presents it to a cylinder 18 equipped with saw teeth, which rotates clockwise as indicated by the arrow 20, and mechanically tear the flock into fibres.
  • the fibres thus opened up remain hooked in the toothing.
  • a jet of air 19 under adjustable pressure and of very high tangential speed acts circumferentially on the cylinder 18 and causes the fibres to fly towards elements which later separate the fibres.
  • This installation which comprises a series of elements successively carrying out the manufacturing operations, comprises a charging device 22, into which the textile fibres are conducted by a pneumatic conduit 21, which charging device is composed essentially of an endless conveyor belt 23, the apron of which is equipped with pins 23, which in its ascending movement entrains clumps of fibres the quantity of which is determined by a con trolling roller 24, the distance of which from the apron is adjustable.
  • the fibres fall in tufts on to a horizontal endless conveyor belt 25 which carries them towards the position A where one of the pneumatic opening systems as described in FIGS. 1, 2, 3 and 4 is installed, whence they are brought by projection into a chamber 26, where the intimate mixing of fibres and resin is effected.
  • the fibres are blown into this chamber 26 by an air current 27, the direction of which is adjustable by means of direction-regulating devices 28, and the quantity delivered of which is controllable by means of a throttle 29.
  • the open fibres are sucked on to the conveyor belt 30 by means of a suction box 31 fixed beneath the belt 30.
  • the fibres are progressively superimposed and before their engagement between the belts 30 and 32, the device 33 of regulable height permits of their equalisation.
  • This device 33 is in the form of a shoe and is provided with a nozzle through which a controllable air jet drives the fibres accumulating before it.
  • liquid resin When using liquid resin, it can be introduced into the fibres by the air jets 4 and 5 of the pneumatic opening system according to FIG. 1.
  • the air jets 4 and 5 of the pneumatic opening system according to FIG. 1.
  • at 34 in the chamber 26 there are provided nozzles introducing a mist of very finely atomised liquid resins into the chamber, which resins coat the fibres while they fly in the eddy which holds them for a certain time in suspension in the air, which time is adjustable by means of the circuit 35 mounted on the box 31 which places the chamber 26 under suction, by withdrawing a portion of air current 27.
  • An external air entry is provided in the top of the chamber 2 6 with adjustable flaps 37.
  • a second conveyor belt 32 of adjustable height takes the fibre-resin mixture which is thus fed into the tunnel 38 for polymerisation.
  • belts 32 and 30 it is possible to form regular, more or less dense mats or cushions of fibres, with strictly flat surfaces.
  • the air current 27 can be heated in order to pre-heat the fibre-resin mixture.
  • a current of hot air is introduced by means of fans 39 into the polymerisation tunnel 38.
  • This current passes through the fleece and furthermore can be directed either from the top downwards or from the bottom upwards or alternately in both directions, according to the nature, thickness and constituents of the finished product to be obtained.
  • conventional speed-variation means (not shown) permits varying the speed of the endless belts 30 and 32.
  • the unwoven felt is either wound on a spindle or it passes into a guillotine 40 which cuts it in sheets of desired length. It can also be cut into belts, the width of which is adjustable.
  • a process for pneumatically parting fibre flocks comprising (a) feeding said flocks into and out of a confined space, and (b) impinging upon said fiber flocks emerging from said confined space at least a pair of high speed air jets flowing in different directions to thereby cause parting of said fibre flocks.
  • a process of pneumatically parting and tearing fibr flocks comprising (a) feeding said fiber flocks through a tube by rotating a screw therein, and (b) impinging upon said fibre flocks leaving said tube an air jet axially aligned with said tube to cause pneumatic parting and tearing of said fibre flocks.
  • a process for tearing and pneumatically parting fib-re flocks comprising (a) feeding said fibre flocks into and out of a confined space, (b) rotating against said fiber flocks emerging from said confined space a sawtoothed cylinder in which said fibre flocks are booked in the toothing thereof, and -(c) impinging tangentially in the rotational direction of said cylinder and air jet of controllable pressure and flow to cause tearing and pneumatic parting of said fibre flocks.
