The present invention provides method for making a wet pressed paper web. An embryonic web of papermaking fibers (120) is formed on a foraminous forming member (11), and transferred to an imprinting member (219) to deflect a portion of the papermaking fibers in the embryonic web into deflection conduits in the imprinting member. The web (120), the imprinting member (219), and the two felt layers (320, 360), are then pressed in a compression nip (300) with a foraminous backing member (350) to mold and dewater the web.

L'invention porte sur un procédé de fabrication de bandes de papier pressées humides. Une bande embryonnaire de fibres papetières (120) est formée sur un élément formateur poreux (11), puis transférée sur un élément d'impression (219) de manière à défléchir une partie des fibres dans les conduits de déflexion de l'élément d'impression. La bande (120), l'élément d'impression (219), et deux couches de feutre (320, 360) sont ensuite comprimés dans la pince (300) de cylindres avec un substrat poreux (350) pour mouler et essorer la bande.
