Abstract
La présente invention porte, selon une réalisation préférée, sur un procédé de formation d'une bande laminée. Ce procédé consiste à produire une bande non tissée (22) de fibres présentant une tension superficielle, cette bande non tissée (22) comportant une première surface, une seconde surface et une pluralité de passages pour le fluide situés entre les première et seconde surfaces en communication fluidique l'une avec l'autre; appliquer un traitement (28) de surface ayant une tension superficielle inférieure à celles des fibres de la bande non tissée formant une bande polymère (200) tridimensionnelle dilatée, à alvéoles macroscopiques; et assembler la bande non tissée de fibres avec la bande tridimensionnelle (200) de façon à former une bande laminée. Cette bande laminée convient notamment pour être utilisée comme feuille supérieure dans un article absorbant jetable.
