Definitions

  • the present invention relates to an improvement made to the devices used for drawing a wick of fibers during a spinning operation making it possible to transform it into a yarn. It relates more particularly to an improved device, which associated with a drawing device proper, makes it possible to condense, transport and optionally give additional drawing to the wick of substantially parallelized fibers leaving said drawing device.
  • the device according to the invention makes it possible to solve these problems.
  • the invention therefore relates to a device for drawing a wick of fibers during a spinning operation making it possible to transform it into a yarn, device of the type according to which a condenser element is arranged in succession.
  • said condensing element is in the form of a movable guide surface on which the fibers are delivered tangentially and which is in the form of a rotary guide, pierced with orifices connected to a suction source, said guide surface making it possible both to exert a tensile force on the end of the fibers delivered by the drawing system and to limit the rise in torsion communicated by the spinning system.
  • the movable guide surface is subjected to the action of a stream of fluid, air for example, the flow of which is such that it promotes, in cooperation with said surface guide, transport and condensation of fibers.
  • a stream of fluid air for example, the flow of which is such that it promotes, in cooperation with said surface guide, transport and condensation of fibers.
  • This flow of fluid can be obtained, for example, by subjecting the guide surface to a vacuum.
  • the action of fluid flow on the guide surface is preferably suppressed in the zone which follows the point where the condensation function has been carried out, that is to say in other words, substantially from from the point where the twist imparted by the spinning system is stopped by said guide surface.
  • the condenser element according to the invention is in the form of a rotary guide, said guide comprising at its periphery an open groove, substantially V-shaped, the bottom of this groove being pierced with orifices connected to a suction source, suction which is suppressed in the area following the point where the stretched wick is condensed and begins to be twisted.
  • the orifices can be arranged in different configurations, for example aligned, or even be in the form of a sinusoid.
  • the faces of the groove can be more or less spaced from one another and form between them an angle which can range from 30 to 160 ° but which, preferably, is generally between 60 and 160 °.
  • a stretching assembly comprising a conventional strap system and a ring and slider spinning system. It is obvious that this is not limiting and that the improvement in accordance with the invention could be used in combination with any system making it possible to stretch a wick of fibers and return it in the form of a yarn.
  • a device is particularly suitable for use in association with stretching systems of the type described in French patents 1 044 932, 1 117 278 and 1 503 693, the device according to the invention then being arranged at the exit of the actual stretching system from the wick.
  • the distance between the outlet of the drawing system itself and the point of contact of the fibers with the surface of the condenser device according to the invention will be adjusted so as to be as small as possible when only desired condense the wick, whereas, on the other hand, if you wish to communicate an additional stretch to said wick by moving the condenser faster than the feed speed of cells, it will be necessary to adapt this distance according to the length treated fibers.
  • the condenser guide according to the invention is in the form of a rotary guide, it is advantageously positioned at the outlet of the drawing system so that the path of the wick in the bottom of the groove of this guide preferably forms an angle between 30 and 90 °.
  • annuities for example by having a fixed cover, either inside or outside, making it possible to close the orifices that said guide surface has, or, possibly using a device, for example suction, acting only on a part displacement of said surface, for example over part of the rotation of the guide when the latter is rotary.
  • the device for drawing a wick of fibers (1) coming from a power source which is not shown consists, on the one hand , by a conventional drawing train (2) comprising, for example, a pair of food cylinders (3), a machon system (4) and a pair of drawing cylinders (5).

Claims (6)

1. Vorrichtung zum Strecken einer Faserlunte (1) während eines Spinnvorganges, durch den die Faserlunte in Garn verwandelt wird, mit einem hinter dem eigentlichen Streckwerk (2) angeordneten Verdichtungselement, dadurch gekennzeichnet, daß das Verdichtungselement (6) eine bewegliche Führungsfläche aufweist, der die Fasern tangential zugeführt werden und die einerseits bestrebt ist, eine Zugkraft auf die Enden der Fasern auszuüben, und andererseits den Bereich begrenzt, über den die der Lunte von der Spinnvorrichtung erteilte Drehung zurückreicht, welche Führungsfläche als drehbare Führung ausgebildet und mit an eine Saugvorrichtung angeschlossenen Löchern (15) versehen ist.
2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die drehbare Führung an ihrem Umfang eine offene Nut (7) mit im wesentlichen V-förmigem Querschnitt aufweist und die an eine Saugvorrichtung angeschlossenen Löcher (15) am Grund dieser Nut angeordnet sind.
3. Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß die Saugwirkung in einer Zone unterdrückt ist, die unmittelbar an den Punkt angrenzt, in dem die Verdichtung der Lunte vollendet ist.
4. Vorrichtung nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß die Löcher (15) längs einer Sinuslinie angeordnet sind.
5. Vorrichtung nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß die drehbare Verdichtungs-Führung (6) am Ausgang des Streckwerkes (2) derart angeordnet ist, daß der Übergangsstelle auf dem Verdichter zur Spinnvorrichtung (8) auf dem Verdichter (6) einen zwischen 30° und 90° betragenden Winkel bildet.
