The invention relates to a method and a device for treating a fibre mass, such as for example a nonwoven or a woven. Such fibre masses are conveyed through a pressing mill for treatment where they are pressed in at least one pressing zone by means of a press-roll. By the pressing, a treatment fluid already present in the fibre mass is pressed out of the fibre mass. After the pressing out of the treatment fluid, a second treatment fluid is introduced into the fibre mass. In order to achieve a distribution of the second treatment fluid in the pressed fibre mass as quickly and homogenously as possible, according to the invention it is provided that the treatment fluid is introduced through the pressing surface area into the fibre mass in an expansion region, where the pressing power exerted by the press-roll is reduced in the moving direction of the fibre mass. Here, the pressing surface area is the surface through which the pressing power acts on the fibre mass.

L'invention concerne un procédé et un dispositif pour le traitement d'une masse fibreuse (21), comme par exemple un non-tissé ou un tissu. De telles masses fibreuses sont conduites aux fins de traitement à travers une machine de pressage (22) dans laquelle ils sont pressés dans au moins une zone de pression (53) au moyen d'un rouleau de pression (51). Le pressage permet d'exprimer de la masse fibreuse (21) un fluide de traitement se trouvant déjà dans la masse fibreuse (21). Une fois le fluide de traitement exprimé, un deuxième fluide de traitement est injecté dans la masse fibreuse (21). L'invention vise à atteindre une répartition aussi rapide et homogène que possible du deuxième fluide de traitement dans la masse fibreuse pressée (21). A cet effet, le fluide de traitement est injecté à travers la surface d'enveloppe de pression (59) dans la masse fibreuse (21), dans une zone d'expansion (55) dans laquelle la pression de pressage exercée par le rouleau de pression (51) décroît dans le sens de déplacement (B) de la masse fibreuse (21). La surface d'enveloppe de pression (59) est la surface par laquelle la pression de pressage agit sur la masse fibreuse (21).
