Title (EN) METHOD FOR MAKING A CALENDER ROLL AND THERMOPLASTIC SHEETS OR FILMS OBTAINED BY CALENDERING WITH SUCH A ROLL
(FR) PROCEDE DE FABRICATION D'UN CYLINDRE DE CALANDRAGE ET FEUILLES OU FILMS THERMOPLASTIQUES OBTENUS PAR LAMINAGE AU MOYEN D'UN TEL CYLINDRE
Abstract:
(EN) The invention concerns a method for making a calender roll whereby after etching the roll (4). superficial metal layer, in particular made of copper, the roll etched metal surface is gated by being subjected to an anode oxidation. Preferably, the roll (4) superficial layer is produced by electroplating, the anode oxidation being carried out in an electrolytic solution (6) derived from the electroplating step. The calender roll is used to obtain, by calendering a thermoplastic resin, a sheet or film comprising at least one matt surface which is more particularly used for making disposable absorbent hygienic articles.
(FR) Le procédé de fabrication d'un cylindre de calandrage consiste après avoir gravé la couche superficielle métallique, notamment en cuivre d'un cylindre (4), à attaquer la surface métallique gravée du cylindre en lui faisant subir une oxydation anodique. De préférence, la couche superficielle métallique du cylindre (4) étant réalisée par électrodéposition, l'oxydation anodique est réalisée dans la solution électrolytique (6) issue de l'étape d'électrodéposition. Le cylindre de calandrage est utilisé pour obtenir, par laminage d'une résine thermoplastique, une feuille ou un film qui comporte au moins une face d'aspect mat et qui est plus particulièrement utilisé dans la confection d'articles d'hygiène absorbants, jetables.
