Abstract

L'invention concerne un système amélioré dans un procédé de fabrication de papier, de formage et d'égouttage mécanique d'une dispersion fibreuse/aqueuse (44) par drainage immergé, dans lequel l'air ne pénètre pas dans la dispersion fibreuse/aqueuse (44) ni dans la bande de papier à mesure qu'elle est formée; l'égouttage mécanique étant effectué par modification de la tension naturelle de la surface de l'eau afin d'augmenter l'écoulement d'eau de la dispersion aqueuse (44) de fibres de fabrication de papier, notamment à l'extrémité la plus humide du système.
