  • Ring spinning machines with traversing device for roving laying are already known per se.

  • the spinning machine has an oscillating device driven by the intermediate drive for moving the roving in the longitudinal direction of the machine, the device comprising yarn guiding rods extending from both sides of the intermediate drive.
  • To drive the oscillating device of an intermediate drive has proven to be of little advantage, since you are bound to the intermediate drive and you constructively limits accordingly. With longer machines, it may be necessary, for example, to use several traversing devices. However, this is not possible in DE1 12012005348T5.
  • JP06-019576Y discloses a head-driven roving laying apparatus connected to a roll via a gear. Again, it is disadvantageous that with longer machines, the traversing device (s) can not be applied anywhere or can. Constructively, this solution is correspondingly very limiting.

Abstract

L'invention concerne un continu à filer à anneaux et un procédé permettant de faire fonctionner le continu à filer à anneaux (1). Le continu comprend au moins un dispositif de va-et-vient (9) pour la pose de la mèche de banc, le dispositif de va-et-vient (9) étant relié à des rails de guidage de mèche de banc (14) ; les rails de guidage de mèche de banc (14) s'étendent à partir du dispositif de va-et-vient (9) dans les deux sens dans la direction longitudinale (x) du continu à filer à anneaux (1). Le continu comprend une pluralité de bancs d'étirage (5) pour l'étirage d'une mèche de banc (6), le dispositif de va-et-vient (9) étant entraîné par le cylindre inférieur d'admission (101) de l'entraînement du banc d'étirage. Le continu à filer à anneaux (1) selon l'invention est avantageux étant donné que l'entraînement selon l'invention du dispositif de va-et-vient (9), en particulier dans le cas de continus de structure plus longue ou très longue, présente une flexibilité supérieure.
