Definitions

  • a drafting system for a spinning machine for stretching a fiber structure, comprising at least a first pair of rolls consisting of a top roll and a bottom roll, and a second pair of rolls consisting of an output top roll and an output bottom roll. ze, and with a downstream of the output roller pair fiber compression for compression of the stretched fiber structure.
  • the fiber compression device has a pneumatic compression device with a fiber-bundling zone and with a suction tube looped around and sucked by a sieve element.
  • FIG. 1 shows a schematic representation of a longitudinal section of a spinning machine according to the prior art, in particular a ring spinning machine. Shown are, by way of example, individual components of the spinning machine, namely a drafting system 2 and a spinning device 10.
  • the drafting system 2 consists of three roller pairs, an input roller pair 3, a pair of apron rollers 4 and a pair of output rollers 5. However, it is also conceivable in the drafting system two or four pairs of rolls.
  • the output roller pair 5 is formed by an output top roller 6 and an output bottom roller 7.
  • the two rollers of a pair of rollers 3, 4 and 5 are pressed against each other and form a nip at their point of contact, a first nip K1 passing through the apron roller.

Abstract

Dispositif d'étirage pour un métier à filer pour l'étirage d'un assemblage de fibres (1), comprenant au moins une première paire de rouleaux (2) composée d'un rouleau supérieur (3) et d'un rouleau inférieur (4), et comprenant une deuxième paire de rouleaux (5) composée d'un rouleau supérieur de sortie (6) et d'un rouleau inférieur de sortie (7), et d'un compresseur de fibres, monté en aval de la paire de rouleaux de sortie (5), pour la compression de l'assemblage de fibres étiré, lequel comprend un dispositif de compression pneumatique comprenant une zone de mise en faisceau des fibres (8) et comprenant un tuyau d'aspiration (9) pouvant être soumis à l'aspiration, entouré par un élément filtrant (21). Un premier point de serrage (K1) est défini par la première paire de rouleaux (2) et un deuxième point de serrage (K2) est défini par la deuxième paire de rouleaux (5), le premier point de serrage (K1) et le deuxième point de serrage (K2) formant un plan de champ d'étirage (24), lequel est traversé par l'assemblage de fibres (1) dans un sens de défilement (15) du premier point de serrage (K1) au deuxième point de serrage (K2). Le rouleau supérieur de sortie (6) présente dans le plan de champ d'étirage (24), vu dans le sens de défilement (15) de l'assemblage de fibres (1), un rideau (A) par rapport au rouleau inférieur de sortie (7). Un troisième point de serrage (K3) est défini par le rouleau supérieur de sortie (6) et l'élément filtrant (21), la longueur de serrage (B) du deuxième point de serrage (K2) au troisième point de serrage (K3) le long d'une surface du rouleau supérieur de sortie (6) étant inférieure à une longueur de pile moyenne de l'assemblage de fibres (1) à étirer.
