  • Another object of the invention is to make the withdrawal of the spinh cable from the spinning device as flexible as possible.
  • the invention has the particular advantage that the degree of wrap between the spinning bucket and the rollers of the take-off unit can be changed and adjusted. This allows states with a high degree of wrap to build up high pull-off forces or states with a low degree of wrap to build up correspondingly low pull-off forces or also for applying and spinning on the spinning cable.
  • the setting range of the wrap angle is between 0 ° and 180 ° on the middle rollers of the take-off unit.
  • at least some of the rollers on the take-off mechanism are movably held on the machine frame in such a way that the guideway of the spinning cable can be changed.

Abstract

L'invention concerne un dispositif et un procédé de filage et d'enlevage d'un câble de filage (15). A cet effet, un dispositif de filage (1) sert à filer à chaud un ou plusieurs faisceaux de fibres, levés ensuite en tant que câble de filage au travers d'un système de levage (2). Le câble de filage (15) est ensuite déposé dans une canette (4) au moyen d'un système de dépôt (3). Pour mettre en oeuvre les forces de levage nécessaires sur le câble de filage (15), ce dernier est guidé par enroulement partiel sur les rouleaux (9, 10) du système de levage (2) dans un guide en forme de S. Pour modifier en particulier le degré d'enroulement sur les rouleaux afin d'appliquer et d'étaler le câble de filage (15), une partie des rouleaux du système de levage (2) est logée de façon mobile sur le bâti du dispositif selon l'invention de manière que le guide du câble de filage (15) peut être modifié.
