Abstract

An absorbent pad (1) such as an incontinence pad comprises a liquid-impervious back sheet (3) with spaced islands (4) of absorbent material thereon. A liquid-pervious cover sheet (7) has pockets (5) formed therein, in which the islands (4) of absorbent material are disposed. The cover sheet is secured, either adhesively or by heat sealing, directly to the impervious sheet (3) along lines that separate the islands of absorbent material and the pockets that contain them. The pad is formed by applying a strip of cover sheet material to a rotating multi-perforate drum and forming the pockets in the cover sheet material either mechanically, or by drawing hot air inwardly through the holes in the drum in the case of a heat-deformable material such as polypropylene fibers. The drum then rotates past a pocket-filling station, where absorbent material such as cellulose fluff is drawn into the pockets by vacuum applied internally of the drum. The cover sheet is then applied to the composite of cover sheet and absorbent material, and is firmly bonded to lines of cover sheet material that are free from absorbent material between the pockets, overlying the bridges that separate the holes through the drum. The composite is then removed from the drum and cut to size.
