A method for coating a dispersion slurry containing a solid SAP dispersed in a dispersion medium on a surface of a substrate sheet are provided. The method is characterized in that a first region and a second region are formed on the surface of the substrate sheet with a convex-and-concave pattern wherein the first region have the coating layer in thicker thickness and the second region have the coating layer in thinner thickness or does not scarcely have the coating layer, by means of positioning the rotating pattern roll over the substrate sheet via the cover film, of supplying the dispersion slurry between the substrate sheet and the cover film while rotating the rotating pattern roll, and of pushing the coating layer with the rotating pattern roll via the cover film, when the coating layer of the dispersion slurry is formed.

L'invention concerne un procédé d'application de revêtement formant un motif, permettant de revêtir la surface d'un matériau de base du type feuille avec une boue de type dispersion possédant du SAP solide réparti dans un milieu de dispersion. Ledit procédé consiste à : disposer un rouleau rotatif à motif sur le matériau de base du type feuille, à travers un film de recouvrement, et à envoyer la boue de type dispersion entre le matériau de base de type feuille et le film de couverture, tout en faisant tourner le rouleau rotatif à motif. On forme ainsi une première zone dans laquelle la couche appliquée est épaisse selon un motif irrégulier sur la surface du matériau de base du type feuille, et une seconde zone dans laquelle la couche appliquée est mince voire inexistante, en pressant le roulant rotatif à motif contre la couche appliquée, à travers le film de revêtement, lorsque la boue de type suspension est formée.
