A method and apparatus for making stretchable absorbent diaper articles. An absorbent material is provided and entangled with a stretchable material to form a stretchable network incorporating the absorbent material. In one embodiment a plurality of foam absorbent material particulates are drawn or accelerated by gravity, vacuum or forced air through a stream of a meltblown adhesive that contacts and entangles the particulates and forms a stretchable network incorporting the particulates.

La présente invention concerne un procédé et un appareil de fabrication d'articles extensibles du type couche absorbante. On réalise un enchevêtrement d'une matière absorbante et d'une matière extensible de façon à former un réseau extensible qui incorpore la matière absorbante. Selon un mode de réalisation, une pluralité de particules de matière absorbante sous forme de mousse sont attirées ou accélérées par la gravité, le vide ou l'air pulsé à travers un courant d'adhésif obtenu par fusion-soufflage qui produit le contact et l'enchevêtrement des particules et forme un réseau extensible incorporant les particules.
