(FR) NOYAUX ABSORBANTS ET PROCÉDÉS DE FORMATION DE NOYAUX ABSORBANTS
Abstract:
(EN) Pulpless absorbent cores and methods of manufacture are disclosed. A first exemplary method may comprise advancing a base carrier sheet in a machine direction, applying a first adhesive onto a top surface of the base carrier sheet, advancing the base carrier sheet within a first particulate material delivery chamber, depositing a first amount of particulate material onto the first adhesive within the first particulate material delivery chamber, applying a second adhesive onto the first amount of particulate material outside of the first particulate material delivery chamber, advancing the base carrier sheet with the first adhesive, the first amount of particulate material, and the second adhesive into a second particulate material delivery chamber, depositing a second amount of particulate material onto the second adhesive within the second particulate material delivery chamber, and applying a top carrier sheet onto the second amount of particulate material.
(FR) L'invention concerne des noyaux absorbants sans pâte et des procédés de fabrication associés. Un premier procédé donné à titre d'exemple peut consister à faire avancer une feuille porteuse de base dans un sens machine, à appliquer un premier adhésif sur une surface supérieure de la feuille porteuse de base, à faire avancer la feuille porteuse de base à l'intérieur d'une première chambre de distribution de matière particulaire, à déposer une première quantité de matériau particulaire sur le premier adhésif à l'intérieur de la première chambre de distribution de matériau particulaire, à appliquer un second adhésif sur la première quantité de matériau particulaire à l'extérieur de la première chambre de distribution de matériau particulaire, à faire avancer la feuille porteuse de base avec le premier adhésif, la première quantité de matériau particulaire et le second adhésif dans une seconde chambre de distribution de matériau particulaire, à déposer une seconde quantité de matériau particulaire sur le second adhésif à l'intérieur de la seconde chambre de distribution de matériau particulaire, et à appliquer une feuille porteuse supérieure sur la seconde quantité de matériau particulaire.
