    (e) un dispositif (48) qui détermine une valeur réelle pour la grandeur caractéristique à partir des signaux de mesure amenés, compare la valeur réelle déterminée a une valeur prescrite prédéfinie et génère un signal électrique de commande conformément à la différence entre la valeur réelle et la valeur prescrite et
    (f) un dispositif de réglage (60) qui commande le dispositif de freinage (4) en fonction du signal de commande électrique amené par le dispositif (48) pour régler automatiquement la quantité du ou des ruban(s) de filasse pour filtre à traiter par l'intermédiaire de la force de freinage exercée.
  13. Dispositif selon la revendication 12, caractérisé en ce que le ruban de filasse pour filtre est un ruban de filasse pour filtre à largeurs multiples, séparé préalablement et séparable.
  14. Dispositif selon la revendication 13, caractérisé en ce qu'il est prévu un dispositif de séparation (16) qui sépare le ruban de filasse pour filtre en rubans individuels.
  15. Dispositif selon la revendication 14, caractérisé en ce que le dispositif de séparation (16) sépare en rubans individuels à largeur simple, le ruban de filasse pour filtre à largeurs multiples sur une ligne destinée à la rupture (17) qui est réalisée préalablement sur le ruban de filasse pour filtre et qui sépare préalablement le ruban de filasse pour filtre.
  16. Dispositif selon l'une quelconque des revendications 12 à 15, caractérisé en ce que le dispositif de mesure détermine individuellement la grandeur caractéristique pour chacune des mèches pour filtre (27.1, 27.2) et émet des signaux correspondants de mesure sur le dispositif de commande qui commande le dispositif de freinage (4) de telle sorte que la quantité à traiter du ruban de filasse pour filtre (6.1, 6.2) à largeur simple est réglée automatiquement.
  17. Dispositif selon l'une quelconque des revendications 12 à 16, caractérisé en ce que le dispositif de freinage (4) a plusieurs paires de rouleaux de freinage séparées l'un de l'autre, a commande non automatique et à travers lesquelles passe respectivement un ruban de filasse pour filtre et en ce que les paires individuelles de rouleaux de freinage exercent une force de freinage sur le ruban de filasse pour filtre les traversant respectivement, la force de freinage étant réglable.
  18. Dispositif selon la revendication 17, caractérisé en ce que le dispositif de freinage (4) comporte deux paires de rouleaux de freinage (4.1, 4.2).
  19. Dispositif selon la revendication 18, caractérisé en ce que les deux paires de rouleaux de freinage (4.1, 4.2) sont couplées et exercent une force de freinage identique.
  20. Dispositif selon l'une quelconque des revendications 12 à 16, caractérisé en ce que le dispositif de freinage (4) présente une paire de rouleaux de freinage à commande non automatique et à largeurs multiples et une paire de rouleaux à commande non automatique et à double largeur ou largeur simple.
  21. Dispositif selon la revendication 12, caractérisé en ce que le dispositif de freinage présente une paire de rouleaux de freinage à commande non automatique et à travers laquelle passe le ruban de filasse pour filtre.
  22. Dispositif selon l'une quelconque des revendications 12 à 16, caractérisé en ce que le dispositif de freinage présente au moins une barre de frein par l'intermédiaire de laquelle le ruban de filasse pour filtre ou les rubans de filasse pour filtre est ou sont guidé(s) et en ce que, au moins l'une des barres de frein est mobile afin que la position des barres de frein l'une par rapport à l'autre puisse être modifiée pour pouvoir régler la force de freinage sur le ou les ruban(s) de filasse pour filtre.
  23. Dispositif selon l'une quelconque des revendications 12 à 16, caractérisé en ce que le dispositif de freinage comporte au moins une tôle de freinage par l'intermédiaire de laquelle le ruban de filasse pour filtre ou les rubans de filasse pour filtre est ou sont guidé(s) et en ce que la tôle de freinage est mobile pour pouvoir régler ou modifier la force de freinage sur le ou les ruban(s) de filasse pour filtre.
  24. Dispositif selon au moins l'une quelconque des revendications 12 à 23, caractérisé en ce que le dispositif de mesure (33) détermine en tant que grandeur caractéristique, la résistance à la traction des mèches pour filtre produites.
  25. Dispositif selon au moins l'une quelconque des revendications 12 à 23, caractérisé en ce que le dispositif de mesure (46) détermine en tant que grandeur caractéristique, la densité ou la masse des mèches pour filtre produites par le dispositif de formatage (3).
