A method of making a flangeless seam for a disposable article including the following steps: a first member (200) of the disposable article is provided. A conductive member (205) is provided on the first member (200). The first member (200) is folded about the conductive member (205) providing opposing first proximal and first distal portions of the first member (200), the conductive member (205) being disposed at least partially between the opposing first proximal and first distal portions. A second member (202) of the disposable article is provided in a folded configuration juxtaposed at least a portion of the first member to form a laminate including the first member (200) and the second member (202). An electromagnetic field is applied across at least a portion of the laminate to heat the conductive member (205) to a temperature which joins at least a portion of the first member (200) and at least a portion of the second member (202). The resulting seam can be opened to provide the article with a flangeless seam.
L'invention porte sur un procédé de fabrication d'une couture sans rebord pour article à jeter comportant les étapes suivantes: sur un premier élément (200) de l'article on dispose un élément conducteur (205); puis on replie le premier élément (200) autour de l'élément conducteur (205) en opposant la première portion proximale et la première portion distale du premier élément (200), l'élément conducteur (205) étant placé au moins partiellement entre la première portion proximale et la première portion distale du premier élément (200) opposées. Un deuxième élément (202) de l'article replié est juxtaposé à au moins une partie du premier élément (200) et du deuxième élément (202). On applique ensuite un champ électromagnétique sur au moins une partie du laminé pour porter l'élément conducteur (205) à une température qui réunit au moins une partie du premier élément (200) à au moins une partie du deuxième élément (205). La couture résultante une fois ouverte donne une couture sans rebord.
