Abstract

L'invention concerne un dispositif permettant de communiquer une torsion alternée à au moins un fil en mouvement, dispositif comportant : - une source d'alimentation en fil à traiter ; - des moyens permettant de communiquer une torsion alternée au fil: - des moyens de guidage du fil en amont et en aval du dispositif de torsion alternée; - des moyens de renvidage des fils formés. Le dispositif se caractérise par le fait que les moyens permettant de communiquer une torsion alternée au fil sont constitués par deux broches de fausse-torsion par friction associées à des moyens guide-fils permettant de mettre le fil en contact alternativement avec l'une ou l'autre de ces broches. Application : obtention de fils à torsion alternée, de fils auto-tordus.
