Abstract
LA PRESENTE INVENTION CONCERNE LES TAMIS DESTINES A PURIFIER LA PULPE FIBREUSE UTILISEE POUR LA FABRICATION DU PAPIER. SELON L'INVENTION, ON UTILISE UN TAMIS CYLINDRIQUE TUBULAIRE ALLONGE 5 DANS LEQUEL TOURNENT DES FEUILLES DE TAMISAGE ROTATIVES 27, 27A, UN PREMIER JEU DE FEUILLES 27 ETANT PLACE AU VOISINAGE DES PORTIONS GAUCHE ET CENTRALE DU TAMIS, TANDIS QU'UN SECOND JEU DE FEUILLES 27A EST DISPOSE DANS LES PORTIONS DROITE ET CENTRALE DU TAMIS. LES DEUX JEUX DE FEUILLES SONT DECALES L'UN PAR RAPPORT A L'AUTRE, ET SE RECOUVRENT PARTIELLEMENT PAR INTERCALEMENT DANS LA PORTION CENTRALE. AINSI, LES PULSATIONS TRANSMISES A LA FRACTION PURIFIEE DE LA PULPE ONT UNE FREQUENCE PLUS ELEVEE, MAIS UNE AMPLITUDE PLUS FAIBLE, D'OU IL RESULTE DES CARACTERISTIQUES D'ECOULEMENT PLUS UNIFORMES. L'INVENTION PEUT SERVIR A PURIFIER LES PULPES FIBREUSES DE PATE A PAPIER.
