Title (EN) A METHOD TO PRODUCE A PAPERBOARD, A PAPERBOARD AND A CORRUGATED BOARD
(FR) PROCÉDÉ DE PRODUCTION DE CARTON, CARTON, ET CARTON ONDULÉ
Abstract:
(EN) The present invention relates to a method for producing a paperboard comprising the steps of; providing a furnish comprising cellulosic fibers, applying the furnish on at least one wire toform a web, dewatering the web on said at least one wire by subjecting the web to a pressure above 150 kPa without the use of a press roll nipand thereafter pressing the dewatered web to form a paperboard. The invention also relates to a paperboardand a corrugated board.
(FR) La présente invention concerne un procédé de production d'un carton comprenant les étapes consistant à : utiliser une composition comprenant des fibres cellulosiques, appliquer la composition sur au moins un fil pour former une bande, déshydrater la bande sur ledit au moins un fil par soumission de la bande à une pression supérieure à 150 kPa sans utilisation d'une ligne de contact de rouleau de presse puis presser la bande déshydratée pour former un carton. La présente invention concerne également un carton et un carton ondulé.
