Abstract
(EN)
This method for manufacturing a sheet member (70) which is for an absorbent article and has a textile (40) and a fiber assembly (50) that is entangled with the textile (40), is characterized by having: an arranging step for arranging the fiber assembly (50) on at least one surface of the textile (40) that is continuous in the conveyance direction; an entangling step for jetting a fluid toward the textile (40) and the fiber assembly (50) after the arranging step, and causing the fiber assembly (50) to be entangled with the textile (40); and a cutting step for cutting both end sections of the fiber assembly (50) in a CD direction that crosses the conveyance direction after the entangling step, wherein the maximum length in the CD direction of the fiber assembly (50) is no less than the length in the CD direction of the textile (40).

L'invention concerne un procédé permettant de fabriquer un élément en feuille (70) qui est destiné à un article absorbant et qui contient un textile (40) et un assemblage de fibres (50) qui est enchevêtré avec le textile (40). Ledit procédé est caractérisé en ce qu'il comprend : une étape d'agencement pour agencer l'assemblage de fibres (50) sur au moins une surface du textile (40) qui est continue dans la direction de transport ; une étape d'enchevêtrement pour projeter un fluide vers le textile (40) et l'assemblage de fibres (50) après l'étape d'agencement et pour amener l'assemblage de fibres (50) à s'emmêler avec le textile (40) ; et une étape de coupe pour couper les deux sections terminales de l'assemblage de fibres (50) dans une direction CD qui croise la direction de transport après l'étape d'enchevêtrement, la longueur maximale dans la direction CD de l'assemblage de fibres (50) n'étant pas inférieure à la longueur dans la direction CD du textile (40).
