A process for autogeneously bonding two cellulosic laminae to form a multi- lamina substrate by high pressure lam-ination. The attachment occurs at selective bond sites wetted with a functional fluid such as water prior to bonding. The process is applicable to multi-lamina substrates formed from laminae treated with chemical softening agents.
L'invention concerne un procédé de liaison autogène de deux strates pour former un substrat multi-strate. La liaison s'effectue au niveau de sites de liaison sélectionnés et humidifiés, avant la liaison, au moyen d'un fluide fonctionnel, tel que l'eau. Ce procédé peut s'appliquer à des substrats multi-strate formés à partir de strates traitées au moyen d'agents chimiques adoucissant.
