 <EMI ID=2.1> 

  
 <EMI ID=3.1> 

  
 <EMI ID=4.1>  tête unique d'étirage et des dispositifs d'étirage à trois cylindres.

  
Le présent perfectionnement a pour but d'apporter

  
aux machinée d'étirage comportant trois ou quatre trains ou groupes de trois cylindres diverses améliorations dues à l'avancement des travaux de recherche. On s'est en effet aperçu qu'il existait une possibilité intéressant. de tirer parti des dispositifs de retenue, de contrôle ou d'étirage trois cylindres, dont un cylindre ou rouleau de pression, habituellement recouvert d'une matière élastique, est pressé sur les deux autres cylindres ou cylindres jumeaux en acier, actionnés suivant un développement identique.

  
On a ainsi imaginé dans le premier train d'utiliser le premier des deux cylindres jumeaux pour maintenir d'une manière absolue la masse de fibres en contact avec le rouleau supérieur, tandis que le second de ces cylindres permet à la matière textile de glisser, lorsqu'elle est pincée par le

  
train d'étirage suivant, ce glissement étant obtenu par des rainures circonférentielles coniques ou trapézoïdales prévues dans ledit second cylindre, rainures dans lesquelles sont  contrôlées les fibres dites "flottantes".

  
Le maintien de la matière risquant dans ces conditions d'être diminué, alors qu'il faut précisément éviter tout glissement des fibres à l'endroit du premier cylindre, il est  prévu, pour améliorer la retenue de la matière en lui permet- 

  
 <EMI ID=5.1> 

  
 <EMI ID=6.1> 

  
 <EMI ID=7.1> 

  
sens approprié, diminuera du reste les risques d'enroulement. 

  
Le second train d'étirage recevant une masse forte-  ment diminuée par l'étirage précédent comporte un second  cylindre avec des rainures circulaires moins profondes et  plus rapprochées.

  
Il est encore prévu de pouvoir modifier l'écartement

  
 <EMI ID=8.1> 

  
étirer.

  
De mime, il est prévu do pouvoir modifier le diamètre du premier cylindre du troisième train pour approcher autant que possible du cylindre rainuré précédent utilisé comme élément de contrôle. Ceci D'applique particulièrement dans les étirages de préparation délivrant des mèches plus légères.

  
Il est également prévu de constituer les cylindres rainurés dit. "de contrôle" de disques serrés côté à cote sur

  
 <EMI ID=9.1> 

  
disques, qui formeront finalement le cylindre, peuvent être en métal ou en matière plastique résistante, voire en porcelaine.

  
Mais il est évident que les rainures peuvent aussi être taillées dans la masse sur toute la longueur du cylindre.

  
Le dessin annexé, à titre d'exemple uniquement, relatif à une étireuse à trois trains, permet de mieux com-

   <EMI ID = 1.1>

  
 <EMI ID = 2.1>

  
 <EMI ID = 3.1>

  
 <EMI ID = 4.1> single head stretching and three-cylinder stretching devices.

  
The purpose of this improvement is to bring

  
the drawing machines comprising three or four trains or groups of three cylinders various improvements due to the progress of research work. We realized that there was an interesting possibility. to take advantage of three-cylinder retainer, control or stretching devices, in which a pressure cylinder or roller, usually covered with an elastic material, is pressed onto the other two steel cylinders or twin cylinders, actuated in a development identical.

  
It was thus imagined in the first train to use the first of the two twin rolls to keep in an absolute manner the mass of fibers in contact with the upper roll, while the second of these rolls allows the textile material to slide, when pinched by the

  
next drawing train, this sliding being obtained by conical or trapezoidal circumferential grooves provided in said second cylinder, grooves in which the so-called “floating” fibers are controlled.

  
The maintenance of the material running the risk under these conditions of being reduced, whereas it is precisely necessary to prevent any sliding of the fibers at the location of the first cylinder, it is provided, to improve the retention of the material by allowing it-

  
 <EMI ID = 5.1>

  
 <EMI ID = 6.1>

  
 <EMI ID = 7.1>

  
proper direction, will also reduce the risk of winding.

  
The second drawing train receiving a mass greatly reduced by the previous drawing comprises a second cylinder with circular grooves which are shallower and closer together.

  
It is still planned to be able to modify the spacing

  
 <EMI ID = 8.1>

  
stretch.

  
Likewise, provision is made to be able to modify the diameter of the first cylinder of the third train to come as close as possible to the previous grooved cylinder used as a control element. This particularly applies in preparation draws delivering lighter strands.

  
It is also planned to constitute the said grooved cylinders. "control" of discs clamped side by side on

  
 <EMI ID = 9.1>

  
discs, which will ultimately form the cylinder, can be made of metal or strong plastic, or even porcelain.

  
But it is obvious that the grooves can also be cut in the mass over the entire length of the cylinder.

  
The accompanying drawing, by way of example only, relating to a three-stage stretching machine, makes it possible to better understand

  
 <EMI ID = 10.1> Figure 1 a section through a three-cylinder drawing train or assembly, and Figure 2 a plan view of a control cylinder.

sible on the input rack, is brought to the first three-cylinder drawing train shown in the drawing.

  
The pressure roller 11, usually lined with elastic material 11 ', can be depending on the high mass:
of fibers at the all-steel inlet and with or without splines:
of various shapes, such as grooves 25 or 26.
