An absorbent device comprises an absorbent layer having an apertured contoured polymer film attached to one surface which surface is provided with a plurality of depressions which communicate directly with the apertures in the film. The device may be produced by separating the polymer film and a carrier material which have been formed into a laminate having impressed therein raised areas defining for example the strands of a net and depressed areas such that upon separation the depressed areas of the film remain attached together with associated portions of the attached absorbent, to the carrier, leaving the raised areas attached to the remainder of the absorbent.

Dispositif absorbant comprenant une couche absorbante qui se compose d'une fine couche de polymère préformée à ouvertures fixée à une surface pourvue de plusieurs dépressions communiquant directement avec les ouvertures se trouvant dans la fine couche. On peut produire ledit dispositif en séparant la fine couche de polymère du matériau porteur, qui ont tous deux la forme d'un stratifié ayant en impression des zones surélevées qui définissent par exemple les fils d'un filet et des zones enfoncées, de sorte que, lors de la séparation, les zones enfoncées, de la fine couche restent collées au porteur avec les parties de l'absorbant qui leur correspondent, tandis que les zones surélevées restent attachées au reste de l'absorbant.
