Abstract

The present invention relates to a method of manufacturing fastener elements for fastening devices that are intended to be affixed to side-parts of an absorbent article of the kind which includes a central part and front and rear side-parts that project out from respective sides of the central part, so as to enable the front and rear side-parts on one and the same side of the central part of the article to be joined together. According to the invention, a central, longitudinally extending, wave-shaped slit is made in a material web which includes at least one continuous row of fastening devices or a continuous string of fastener devices or fastener-device blanks which extends in the longitudinal direction of the material web. Transverse slits are made on both sides of the material web up to the region of the wave-shaped slit, these transverse slits being mutually spaced in the longitudinal direction of the web at a continuously repeated spacing sequence. The invention also relates to fastener-device elements manufactured in accordance with the method.

Dependent claims

An absorbent article comprising:

a central part, front and rear side parts projecting out from respective sides of said central part, such that the central part, front and rear side parts on one and the same side of the central part of the article are joined together;
at least one fastener element attached to one of the front side part and the rear side part and at least one fastener device element attached to the other of the front side part and the rear side part such that said at least one fastener element is connectable to said at least one fastener device element;
said at least one fastener element lying in a plane and having at least one continuous row of fastener devices and a row of several identical tongues projecting outwardly in a wave shape and in the plane of the at least one fastener element perpendicular to the row of fastener devices with a fastener device on each tongue;
and
said fastener device element lying in a plane and having a plurality of identical tongues projecting outwardly in a wave shape and in the plane of the fastener device element and having a plurality of studs extending substantially perpendicularly from the plane of said tongues with a stud on each tongue;
wherein said studs of said fastener device element are engageable with said fastener devices of said fastener element to substantially maintain said front and rear side parts in a position to support said absorbent article on a wearer thereof.
