    Abstract: A fluid permeable covering sheet (9)is disclosed for an absorbent article such as a diaper, a sanitary napkin, an incontinence protector or the like, wherein heated needles (4) are brought to penetrate a sheet of textile material (1) comprising at least one thermoplastic component, whereby the thermoplastic component closest to the needles (4) melts, whereafter the needles (4) are removed and the heated material (1) is passed through at least one nip of rollers (7) so that the thermoplastic component closest around the apertures is smoothed out into a substantially smooth material surface around the apertures, whereafter the thermoplastic component is brought to solidify. An apertured covering sheet (not shown) is also disclosed for an absorbent article manufactured in accordance with the method, as is an absorbent article (not shown) provided with a covering sheet manufactured in accordance with the method.

    IPC: A61F13/511 ,  A61F13/15 ,  B32B7/04 ,  D04H13/00

    Abstract: The invention relates to a material laminate for use as a covering sheet on absorbent articles such as sanitary napkins, incontinence protectors, diapers, pant diapers, or the like. The material laminate comprises a first, fluid pervious fibrous material layer and a second fluid pervious porous material layer, wherein at least one of the two material layers comprises thermoplastic material and wherein the two material layers are mutually connected by means of the covering material laminate exhibiting bond sites within which the thermoplastic material has been caused to at least partially soften or melt and thereby bond the two material layers together. In the planar extension, the material laminate exhibits two side portions extending in the length direction and having an extension in the width direction from a respective longitudinal side edge and a distance in towards the longitudinal central axis of the material laminate and a central portion positioned between the side portions in the planar extension of the material laminate, wherein the first material layer and the second material layer in the central portion of the material laminate are intermittently bonded together with a first bond pattern and that the first material layer and the second material layer in the two side portions of the material laminate are intermittently bonded together with a second bond pattern wherein the percentage bonded area in relation to the total area in the two side portions is greater then the percentage bonded area in relation to the total area in the central portion. The invention further pertains to an absorbent article comprising the material laminate.
