METHOD OF MANUFACTURING BRIDGED ABSORBENT STRUCTURES

A method of manufacturing an absorbent web includes moving a foraminous member in a machine direction. The foraminous member has at least one masking plate with a partitioned area including at least one partition defining a plurality of segments. The method further includes drawing air through the f...

Zusammenfassung:	A method of manufacturing an absorbent web includes moving a foraminous member in a machine direction. The foraminous member has at least one masking plate with a partitioned area including at least one partition defining a plurality of segments. The method further includes drawing air through the foraminous member and depositing fibrous material onto the foraminous member to form an absorbent web. The absorbent web has a bridged area with a reduced basis weight corresponding to the partitioned area of the masking plate. The bridged area has vertical interfaces separating web segments and fibrous material at least partly bridging the vertical interfaces. L'invention concerne un procédé de fabrication d'une bande absorbante qui comprend le déplacement d'un élément foraminé dans un sens machine. L'élément foraminé a au moins une plaque de masquage comprenant une zone séparée comprenant au moins une cloison définissant une pluralité de segments. Le procédé comprend en outre l'aspiration d'air à travers l'élément foraminé et le dépôt de matériau fibreux sur l'élément foraminé pour former une bande absorbante. La bande absorbante a une zone pontée présentant un poids de base réduit correspondant à la zone séparée de la plaque de masquage. La zone pontée a des interfaces verticales séparant des segments de bande et un matériau fibreux reliant au moins partiellement les interfaces verticales.
