VERFAHREN ZUM AUTOGENEN VERBINDEN VON SCHICHTEN EINES MEHRSCHICHTIGEN ZELLULOSESUBSTRATS

摘要

A process for autogeneously bonding two cellulosic laminae to form a multi-lamina substrate by high pressure lamination. 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.
