A method for making a textured tissue sheet on a conventional tissue making machine using a conventional cylindrical drum dryer creates a product that is remarkably bulky, soft, and wet resilient. A combination of rush transfer and sheet molding with three-dimensional fabrics is combined with the step of web inversion to ensure that the surface of the web which was molded onto a first textured transfer fabric is the surface which is placed against the surface of the cylinder dryer. Web inversion improves machine productivity and enhances physical properties of the web.

L'invention se rapporte à un procédé de fabrication d'une feuille de papier ménager texturé sur une machine classique de fabrication de papier ménager mettant en oeuvre un séchoir à tambour cylindrique classique. Ledit procédé permet la fabrication d'un produit remarquablement gonflant, doux et présentant une certaine élasticité à l'état humide. On combine à l'étape d'inversion de bande des étapes de transfert rapide et de moulage en feuille avec des tissus à structure tridimensionnelle dans le but de s'assurer que la surface de la bande qui a été moulée sur un premier tissu de transfert texturé est la surface qui est placée contre la surface du sécheur cylindrique. L'inversion de la bande permet d'accroître la productivité de la machine et d'améliorer les propriétés physiques de la bande.
