Definitions
- the present invention relates to a spinning method centrifugal designed to continuously produce a length of wire indefinite, according to which one alternately feeds two pots centrifugal spinning through two supply lines respective, both born at the exit of a train stretcher, periodically separating the wire at the junction of the two conduits, communicating a pretortion to the bundle of fibers leaving the stretching train by an air jet helical and directing this end into the other said conduits, the wire is pinched along its path between said junction and the spinning pot in which it is brought, to stop the rise of the twist along the wire, beyond the pinch zone to periodically separate the wire.
- the object of the present invention is to remedy the disadvantages mentioned above.
- the subject of this invention is, first of all a centrifugal spinning process for producing a wire in device according to claim 1, as well as a device for centrifugal spinning intended to produce a continuous wire according to claim 2.
- the attached drawing illustrates, schematically and by way of example of an embodiment of a spinning device for the implementation of the process which is the subject of the present invention.
- Figures 1 to 4 are four sectional elevation views of the spinning device illustrating four phases characteristics of the spinning process.
- the spinning device which is the subject of the invention comprises a stretching train of which only the output, in the form of two rollers 1, 2 is shown.
- a conduit 3 is arranged for collect the drawn bundle of fibers 4 leaving the drawing train.
- This conduit 3 is divided into two branches 5 and 6 whose outlets are aligned on two 5 'conduits, respectively 6 ', which lead respectively into two centrifugal spinning pots 7 and 8.
- Mechanisms for spread the wire along the inner walls of the pots are not not shown, but can be like those shown and described in EP-A1-515,762.
- Two storage coils 9 and 10 are arranged in the space separating the conduits 5 and 6 from the conduits 5 'and 6'. With respect to each of these storage coils 9 and 10, of the other side of the path of the wire passing from the outlet of the conduits 5, 6 at the entrance to conduits 5 ', 6', there is a pusher 11, 12 secured to a piston 13, respectively 14, mounted in a pneumatic cylinder 15, respectively 16, at against the pressure of a return spring 17, respectively 18.
- a winding coil 19 is intended for collect the wire from the storage coils 9 and 10, by example, as described in the aforementioned EP 925000015.0, this part of winding the wire not being necessary for the understanding of the present invention.
- a series of nozzles 20 is distributed angularly around of conduit 3. These nozzles are selectively connected by through a timer 21 to an air source under pressure S. These nozzles 20 are arranged so as to create, in the duct 3, a helical air flow under pressure directed downstream. Two other series of nozzles 22 and 23 are arranged downstream in each of branches 5 and 6. They are selectively connected to the air source under pressure S by timer 21 and a switching valve 24. These nozzles 22 and 23 are also oriented to form a helical air flow in branches 5 and 6.
- Two additional nozzles 25 and 26 can be directed in the axis of the wire at the birth of each branch 5 and 6 and located in the plane common to these two branches. These nozzles 25 and 26 are selectively connected to the source of pressurized air S by the timer 21 and the valve switching 24.
- the pressurized air source S is still connected selectively, via timer 21 and the switching valve 24, with two pneumatic cylinders 15, 16, as well as two ejectors 27 and 28, located along the ducts 5 'and 6', respectively, to create a vacuum at the entrance to these conduits.
- the switching valve 24 switches the pressure source S on two circuits separate, A and B, circuit A supplying the series of nozzles 22, the nozzle 26, the pneumatic cylinder 16 and the ejector 27, circuit B supplying the series of nozzles 23, the nozzle 25, the pneumatic cylinder 15 and ejector 28.
- the series of nozzles 20 is powered whenever the timer connects the circuits A or B at the source of pressurized air S.
- Figure 1 illustrates a phase of the spinning cycle at during which the wire of the centrifugal spinning pot 7 is transferred to the storage reel 9, while the wire is in spinning course in the other pot 8. Simultaneously, the wire previously wound on the storage reel 10 is transferred to the winding coil 19.
- the timer switches the switching valve 24 on circuit A above, which is drawn in a strong line in FIG. 2, which illustrates the effect produced by this pressurization of the circuit A.
- the pusher 12 clamps the wire against the storage reel 10. This pinching the wire isolates the part of the wire located between the pinch point and the exit of the stretching train 1, 2 of the source of torsion communicated to the wire by the pot of spinning 8. Simultaneously, the nozzles 20 communicate a twist to that portion of the wire.
- the nozzles 22 exert a vacuum at the inlet of conduit 5 and that the nozzle 26 can project a jet of pressurized air against the wire, this one, presenting practically no more cohesion, is breaks in the place where it is stressed by the depression due to the nozzles 22 and by the jet from the nozzle 26.
- the coil of storage 10 rotated in the direction of the arrow wind both the portion of wire leaving the conduit 6 and the wire from the pot 8.
- the end of the fiber bundle leaving the stretching train 1, 2 it is immediately subjected to a twisting effect by the nozzles 20, so that this beam of fibers regains cohesion.
- the distance between the pinch point of the rollers 1, 2 and the nozzles 20 is chosen lower than the average fiber length. Then at the entrance to junction 5, the wire receives a communicated S-twist by the nozzles 22, which gives it a cohesion suitable for reach the spinning pot 7.
- the delay between the nozzle (20) and the nozzles (22, 23) must be a few fractions of a second, which is not possible with the "sensitivity" of technology the timer; computerized means of control are preferable.
- This cycle also repeats continuously as long as necessary.

- Procédé de filage centrifuge destiné à produire en continu un fil de longueur indéfinie selon lequel on alimente alternativement deux pots de filage centrifuge (7,8) par deux conduits d'alimentation respectifs (5,5'; 6,6') prenant tous deux naissance à la sortie d'un train étireur (1,2), en séparant périodiquement le fil au niveau de la jonction des deux conduits, en communicant une prétorsion au faisceau de fibres sortant du train étireur par un jet d'air hélicoïdal et en dirigeant une extrémité du fil dans l'autre desdits conduits, le fil de chaque pot de filage étant transféré sur une bobine de stockage (9, 10) par un poussoir (11, 12) qui pince ce fil le long de sa trajectoire entre ladite jonction et le pot et l'applique contre cette bobine de stockage au moment précis où le fil est séparé, caractérisé en ce que pour séparer périodiquement le fil on induit, simultanément au pincement du fil, une aspiration dans l'autre desdits conduits (5,6), en créant un écoulement d'air hélicoïdal en direction du pot de filage (7,8) qu'il est destiné à alimenter en fil, de sorte que la portion du fil située a la jonction des deux conduits, isolée de la source de torsion suite au pincement du fil, perd sa cohésion et se sépare du reste du fil sous l'effet de l'aspiration crée dans l'autre desdits conduits dans lequel l'écoulement d'air hélicoïdal le fait avancer en direction de l'autre pot de filage en le soumettant à une prétorsion, on arrête ledit écoulement hélicoïdal dès que le fil est entré en contact avec la face interne du pot de filage centrifuge et on répète cette opération en sens inverse, et ainsi de suite autant de fois que désiré.
