Description

       

  " Filière destinée plus spécialement aux matières

  
filables thermo-plastiques et fusibles ".

  
L'invention a pour objet une filière, qui est appropriée notamment pour la filature de matières filables très

  
visqueuses, par exemple thermoplastiques ou fusibles, telles que de l'éther de oellulose, des composés de polyvinyle

  
ou des produits de polyoondensation tels que des polyamides,

  
et qui diffère des filières en usage jusqu'à présent par

  
le fait que le fond de la filière oomporte des bourrelets

  
concentriques à travers lesquels passent les perforations

  
de la filière. Ces perforations se trouvent donc dans des anneaux en forme de nervures, qui sont produits par estampage ou par refouillement en pleine matière, en veillant à oe que la largeur de ces nervures ne dépasse pas considérablement

  
le diamètre des perforations. En tout cas, la face arêtière doit être au moins de largeur telle que les ouvertures se trouvent toutes nettement dans un même plan. Par cette disposition, le raccord de filage des matières filables mentionnées oi-dessus est considérablement facilité et l'enlèvement de restes durcis, qui est important pour une filature exempte de troubles, est rendu possible. Les nouvelles filières, qui peuvent être fabriquées facilement et avec une grande précision ont, en outre, l'avantage que la résistance à de hautes pressions est augmentée par les nervures annulaires. La forme des filières est, au surplus, secondaire; elles peuvent avoir la forme de chapes ou de plaques. Comme matière de construction, on emploie, de préférence, des métaux, par exemple le

  
 <EMI ID=1.1> 

  
si de la matière céramique qui possède l'avantage d'une plus lente émission de ohaleur.

  
Le dessin annexé représente, à titre d'exemple, quelques formes typiques de filières d'après l'invention.

  
Les figures 1 à 4 montrent en coupe des formes de filières, telles qu'elles sont fabriquées de préférence en métal. Les figures 5 à 7 montrent des plaques de fond, plus spécialement en matière céramique ou en matière de construction, produites par refouillement en pleine matière. La figure 8 est une vue du fond de la filière d'après la figure 3, et la figure 9 est une vue du fond de la filière d'après la figure 7. La figure 7 diffère des formes des figures 5 et 6,d'une part/par deux nervures concentriques avec trous de filières et, d'autre part,par le fait que l'entrée des perforations est en forme d'entonnoir de manière connue. Les  <EMI ID=2.1> 

  
Les filières d'après l'invention se sont montrées particulièrement bien appropriées pour la filature de résines formatrices de fils du type des polyamides, décrites dans la Patente aux Etats-Unis 2.071.051 du 16 février 1937 et aussi dans la demande de brevet allemand I. 61.608 IV o/12.0 du
10 juin 1938.



  "Sector intended more specifically for materials

  
thermoplastic wire cables and fuses ".

  
The subject of the invention is a die which is suitable in particular for the spinning of highly spinnable materials.

  
viscous, e.g. thermoplastics or fusible, such as cellulose ether, polyvinyl compounds

  
or polyoondensation products such as polyamides,

  
and which differs from the channels in use until now by

  
the fact that the bottom of the sector has beads

  
concentric through which the perforations pass

  
of the sector. These perforations are therefore found in rings in the form of ribs, which are produced by stamping or by rewinding in full material, making sure that the width of these ribs does not considerably exceed

  
the diameter of the perforations. In any case, the hip face must be at least of a width such that the openings are all clearly in the same plane. By this arrangement, the spinning connection of the above-mentioned spinnable materials is considerably facilitated and the removal of hardened residues, which is important for trouble-free spinning, is made possible. The new dies, which can be manufactured easily and with great precision, have the further advantage that the resistance to high pressures is increased by the annular ribs. The form of the dies is, moreover, secondary; they can be in the form of screeds or plates. As a construction material, preferably metals, for example

  
 <EMI ID = 1.1>

  
if ceramic material which has the advantage of a slower emission of heat.

  
The accompanying drawing shows, by way of example, some typical forms of die according to the invention.

  
Figures 1 to 4 show in section forms of die, as they are preferably made of metal. Figures 5 to 7 show bottom plates, more especially of ceramic material or of construction material, produced by rewinding in full material. Figure 8 is a bottom view of the die from Figure 3, and Figure 9 is a bottom view of the die from Figure 7. Figure 7 differs from the shapes of Figures 5 and 6, d 'on the one hand / by two concentric ribs with die holes and, on the other hand, by the fact that the entry of the perforations is funnel-shaped in a known manner. The <EMI ID = 2.1>

  
The dies according to the invention have been shown to be particularly well suited for the spinning of yarn-forming resins of the polyamide type, described in United States Patent 2,071,051 of February 16, 1937 and also in German patent application I. 61.608 IV o / 12.0 of
June 10, 1938.
