Description
<EMI ID=1.1> La présente invention est relative à un appareil à filer
<EMI ID=2.1>
forës étroitement rapprochés, tournant dans le même sens, dans la région de coin desquels sont situées des zones d'aspiration tournées l'une vers l'autre, les fibres introduites en suspension dans l'air étant tordues ensemble dans la région de coin et le retrait du
fil formé s'effectuant dans la direction longitudinale des tambours, tandis que le fil est empêché de tourner.
Des appareils de ce genre sont déjà connus (DT-OS
2 449 583) et donné de bons résultats. Il se produit seulement
des difficultés lorsqu'il s'agit de fabriquer des fils fins, en particulier de coton, parce qu'il s'agit de fibres courtes, ayant une longueur maximale de 50 mm, qui sont très souples et très minces et qui, par suite, peuvent facilement s'accrocher dans
les trous des tambours d'aspiration ou être aspirées au travers.
En outre, avec de telles fibres, le frottement contre les tambours est le plus souvent trop grand pour que l'on obtienne une torsion et un filage satisfaisants.
Aussi, l'invention a pour but de perfectionner l'appareil défini plus haut, de façon telle qu'il convienne à la fabrication de fils fins, en particulier de fils de coton.
Selon l'invention, ce problème est résolu par le fait
que les trous des tambours, dont la surface totale représente environ 20 à 50 % de la surface latérale perforée des tambours,
ont un diamètre d'un millimètre au maximum.
Il est apparu qu'avec des tambours à trous aussi fins,
le risque d'aspiration des fibres est éliminé et que le frottement entre les fibres et la surface latérale des tambours est réduit
<EMI ID=3.1>
façon satisfaisante. La surface totale des trous des tambours doit se situer dans la gamme indiquée, car autrement, le courant d'air de transport des fibres entraîne trops peu d'air et il peut se produire des accumulations ou des tourbillons qui nuisent a la formation du fil.
Un exemple d'exécution de l'invention est représenté par le dessin en coupe verticale sous forme purement schématique.
<EMI ID=4.1> <EMI ID=5.1>
un côté frontal des tambours est prévue une paire de cylindres
<EMI ID=6.1>
bours le fil formé entre ceux-ci, tout en l'empêchant de tourner. Les fibres sont fournies par un groupe de détachement de fibres essentiellement formé d'une admission de matière 8 et d'un tambour de carde denté 9 duquel les fibres s'envolent pour arriver directe-
<EMI ID=7.1>
de la surface latérale perforée du tambour et qui ont un diamètre de 1 mm au maximum. Avec ces dimensions, l'appareil convient très
<EMI ID=8.1>
<EMI ID = 1.1> The present invention relates to a spinning apparatus
<EMI ID = 2.1>
closely spaced bores, rotating in the same direction, in the corner region of which are located suction zones facing each other, the fibers introduced suspended in the air being twisted together in the corner region and the withdrawal of
formed yarn running in the longitudinal direction of the drums, while the yarn is prevented from turning.
Devices of this kind are already known (DT-OS
2,449,583) and gave good results. It only occurs
difficulties when it comes to making fine yarns, especially cotton, because they are short fibers, having a maximum length of 50 mm, which are very flexible and very thin and which, therefore , can easily hang in
the holes of the suction drums or be sucked through.
In addition, with such fibers, the friction against the drums is most often too great for satisfactory twist and spinning to be obtained.
Also, the object of the invention is to improve the apparatus defined above, so that it is suitable for the manufacture of fine threads, in particular cotton threads.
According to the invention, this problem is solved by the fact
that the holes of the drums, the total surface of which represents approximately 20 to 50% of the perforated lateral surface of the drums,
have a diameter of one millimeter at most.
It turned out that with drums with such fine holes,
the risk of fiber suction is eliminated and friction between the fibers and the side surface of the drums is reduced
<EMI ID = 3.1>
satisfactorily. The total area of the holes in the drums must be within the range indicated, otherwise the air flow transporting the fibers will entrain too little air and there may be build-ups or vortices which interfere with the formation of the yarn. .
An exemplary embodiment of the invention is represented by the drawing in vertical section in purely schematic form.
<EMI ID = 4.1> <EMI ID = 5.1>
a front side of the drums is provided a pair of cylinders

burs the wire formed between them, while preventing it from turning. The fibers are supplied by a fiber detachment group essentially formed of a material inlet 8 and a toothed card drum 9 from which the fibers fly off to arrive directly.
<EMI ID = 7.1>
of the perforated side surface of the drum and which have a maximum diameter of 1 mm. With these dimensions, the device is very suitable
<EMI ID = 8.1>
