Abstract
L'ADDITION A POUR OBJET DES PERFECTIONNEMENTS AU PROCEDE ET A LA MACHINE DE TRAITEMENT D'UNE MATIERE PREMIERE CONTENANT DES FIBRES DE CELLULOSE. SELON L'ADDITION, ON REALISE LE DEFIBRAGE DE LA MATIERE EN AU MOINS DEUX ETAPES SUCCESSIVES, CHAQUE ETAPE COMPRENANT LE PASSAGE DE LA MATIERE DANS UNE ZONE D'ENTRAINEMENT ET UNE ZONE DE FREINAGE CONTROLANT LE PASSAGE SELECTIF VERS L'ETAPE SUIVANTE DE LA MATIERE AYANT ATTEINT UN DEGRE DE DEFIBRAGE CHOISI, CE DEGRE AUGMENTANT D'UNE ETAPE A LA SUIVANTE. DE PLUS, ON REALISE LE BLANCHIMENT DE LA PATE PAR INJECTION D'UN REACTIF DE BLANCHIMENT DANS LA MACHINE DE TRAITEMENT AU COURS DU PROCESSUS DE DEFIBRAGE. L'INVENTION S'APPLIQUE SPECIALEMENT A LA FABRICATION DE LA PATE A PAPIER A PARTIR DE COPEAUX DE BOIS.
