Abstract

Appareil de production d'étoffes non tissées à longues fibres, par dépôt de filaments sur une surface collectrice. Il comprend un éjecteur alimenté en air comprimé et en filaments, et comportant un tube 3 de sortie sur le tronçon extrême duquel est emmanché un dispositif 5 d'étalement. La profondeur sur laquelle le tube 3 pénètre dans le dispositif 5 peut être réglée de manière que les fibres entraînées par l'air comprimé se déposent sur la surface collectrice en formant un cercle ou une ellipse. Il est ainsi possible de régler les valeurs relatives de résistance longitudinale et de résistance transversale de la bande ainsi produite. Domaine d'application: production d'étoffes non tissées à longues fibres.Apparatus for producing long fiber nonwoven fabrics by depositing filaments on a collecting surface. It comprises an ejector supplied with compressed air and filaments, and comprising an outlet tube 3 on the end section of which a spreading device 5 is fitted. The depth to which the tube 3 enters the device 5 can be adjusted so that the fibers entrained by the compressed air are deposited on the collecting surface forming a circle or an ellipse. It is thus possible to adjust the relative values of longitudinal resistance and transverse resistance of the strip thus produced. Field of application: production of long fiber nonwoven fabrics.
