Patent

CA 2215944

It has already been proposed to use measuring devices to detect spectral and/or physical characteristics with a subsequent neuronal network in the production of de-inked cellulose, where corrections for an existing regulating or control device for the operating means are obtained. According to the invention, the measuring devices are used to check the raw materials for paper and cardboard production and/or their intermediate or end products. It thus becomes possible to discover data on the quality of the paper and cardboard from which signals for backward and/or forward control can be derived.

Dans la production de cellulose désencrée, il a d'ores et déjà été proposé d'utiliser des dispositifs de mesure pour détecter les caractéristiques spectrales et/ou physiques avec un réseau neuronal subséquent, ce qui permet d'obtenir des valeurs de correction pour un dispositif de régulation ou de commande destiné aux éléments du système. Selon l'invention, les dispositifs de mesure permettent de détecter les produits de base utilisés pour produire du papier et du carton et/ou leurs produits intermédiaires ou leurs produits finis. Ce procédé permet notamment de fournir des informations sur la qualité du papier et du carton, des signaux pouvant être dérivés pour une commande en aval et/ou en amount.
