Abstract:
A method of producing a fluid permeable covering sheet for an absorbent article, said method comprising:creating apertures in a sheet of a fibrous textile material, said fibrous textile material comprising at least one thermoplastic component, the apertures being created by bringing heated needles having a temperature exceeding the melting temperature of the thermoplastic component to penetrate the sheet of fibrous textile material, whereby the heated needles melt the thermoplastic component closest to the needles, whereafter the needles are removed from the sheet of fibrous textile material, and after creating the apertures, passing the heated fibrous textile material through at least one nip of rollers between two compression rollers, whereby the thermoplastic component closest around the apertures is smoothed out in the plane of the sheet of fibrous textile material so that a substantially smooth material surface is obtained around the apertures, whereafter the thermoplastic component is brought to solidify.
