Abstract

Procédé pour fabriquer un produit fibreux cellulosique multiplex, consistant à déposer des fibres cellulosiques sous forme humide pour former des première et seconde couches déposées sous forme humide, à déposer des fibres cellulosiques sous forme sèche pour former au moins une couche déposée sous forme sèche, et à intercaler la (ou les) couche(s) déposée(s) sous forme sèche entre les couches déposées sous forme humide pour obtenir ledit produit, la ou chaque couche déposée sous forme sèche 32 est consolidée sous l'action de la chaleur et de la pression une fois qu'elle a été combinée avec au moins une des couches déposées sous forme humide 33. Application notamment aux cartons pour boîtes pliantes.A process for making a multiplex cellulosic fibrous product, comprising depositing cellulosic fibers in wet form to form first and second wet-deposited layers, depositing cellulosic fibers in dry form to form at least one dry-deposited layer, and in interposing the layer (s) deposited in dry form between the layers deposited in wet form to obtain said product, the or each layer deposited in dry form 32 is consolidated under the action of heat and pressure once it has been combined with at least one of the layers deposited in wet form 33. Application in particular to cartons for folding boxes.
