Abstract

L'invention concerne un dispositif d'homogénéisation d'un courant fluidique chargé de fibres. La paroi extérieure du conduit fluidique est graduellement profilée jusqu'à une forme rectangulaire présentant la largeur désirée à l'extrémité de décharge et est pourvue d'au moins un poste mélangeur se composant de deux types de chicanes intérieures qui ne se touchent pas mutuellement, et il est prévu des supports dont les grandes dimensions sont orientées essentiellement parallèlement à la grande dimension de la paroi extérieure rectangulaire, de manière que l'écoulement fluidique rectangulaire entrant soit divisé en deux écoulements partiels essentiellement égaux et que chaque écoulement partiel soit canalisé de manière à suivre un trajet qui assure son reprofilage de section droite en deux phases jusqu'à la largeur initiale individuelle et qui puisse en outre poursuivre son trajet dans une position située respectivement en dessous ou au-dessus de l'autre écoulement partiel. Application : fabrication de nappes non tissées.
