Abstract
(EN)
Provided is a method for manufacturing a sheet member (70) for absorbent articles, the sheet member (70) having a woven fabric (40) and a fiber assembly (50) entangled with the woven fabric (40). The method is characterized by comprising: a first conveying step in which at least the fiber assembly (50) is conveyed using a conveyor (130a); and a second conveying step in which the woven fabric (40), and the conveyed fiber assembly (50) from the first conveying step are further conveyed using a rotating body (150) having a suction mechanism, wherein in the second conveying step, the woven fabric (40) is conveyed in contact with the circumferential surface of the rotating body (150), and a fluid is jetted in the radially inward direction of the rotating body (150) to entangle the fiber assembly (50) with the woven fabric (40).

L'invention concerne un procédé permettant de fabriquer un élément en feuille (70) pour des articles absorbants, l'élément en feuille (70) ayant un tissu tissé (40) et un assemblage de fibres (50) entremêlé avec le tissu tissé (40). Le procédé est caractérisé en ce qu'il comprend : une première étape de transport dans laquelle au moins l'assemblage de fibres (50) est transporté à l'aide d'un transporteur (130a) ; et une seconde étape de transport dans laquelle le tissu tissé (40) et l'assemblage de fibres (50), transporté dans la première étape de transport, sont ensuite transportés à l'aide d'un corps rotatif (150) ayant un mécanisme d'aspiration. Dans la seconde étape de transport, le tissu tissé (40) est transporté en contact avec la surface circonférentielle du corps rotatif (150), et un fluide est projeté dans la direction radialement vers l'intérieur du corps rotatif (150) pour entremêler l'assemblage de fibres (50) avec le tissu tissé (40).
