An absorbent article, such as a diaper, a pants-type diaper, an incontinence protector or a pants-like sanitary napkin, having a front part, a rear part and an intermediate central part. The article includes an absorbent body enclosed between an inner, liquid-permeable sheet and a liquid-impermeable outer sheet, and fastener devices for releasably connecting side-portions of the front and rear parts. The fastener devices are made of a renewable material. The fastener devices are welded to at least one of the sheets of the article and the fastener devices and the sheets are made of a material having a glass transition temperature which lies between 50-60&deg; C. and a melting point which lies between 140-180&deg; C., preferably between 150-175&deg; C.

Diaper that includes weldable fastener devices

The invention relates to a method and to an apparatus for perforating a web of material intended to form an outer casing sheet of absorbent articles. As the web is advanced, the web is first provided with a large number of mutually separated cuts in the nip defined between raised plateaus on a matrix cylinder and circumferentially extending knife-edges of a cutting cylinder. The web is then deformed transversely to its plane at parts which border on each cut. The invention also relates to a perforated outer casing sheet which includes recesses in the form of mutually adjacent elongated channel-like grooves.
