Abstract

Appareil pour la production de non-tissés filés-liés à partir de filaments continus, une filière étant prévue pour filer les filaments continus et une chambre de refroidissement étant prévue pour refroidir les filaments filés. Une cabine d'alimentation en air à partir de laquelle l'air de refroidissement peut être introduit dans la chambre de refroidissement est agencée sur deux côtés opposés de la chambre de refroidissement. Une conduite d'alimentation pour l'air de refroidissement est connectée à chaque cabine d'alimentation en air, la section transversale de la conduite d'alimentation à la transition de l'air de refroidissement dans la cabine d'alimentation en air augmentant jusqu'à la section transversale de la cabine d'alimentation en air, la surface en coupe transversale de la cabine d'alimentation en air étant au moins deux fois plus grande que la section transversale de la conduite d'alimentation. Dans chaque cabine d'alimentation en air, au moins un redresseur d'écoulement est prévu et à distance du redresseur d'écoulement au moins un élément plat d'homogénéisation pour homogénéiser le flux d'air de refroidissement introduit dans la cabine d'alimentation en air. L'élément d'homogénéisation plat présente une pluralité d'ouvertures, la surface ouverte libre de l'élément d'homogénéisation étant de 1 à 40% de la surface totale de l'élément d'homogénéisation.
