Abstract

DISPOSITIF DE REGLAGE DU GRAMMAGE DANS DES MACHINES A PAPIER. LE DEBIT DE LA SUSPENSION EST REGLE A UNE VALEUR QUI EST PROPORTIONNELLE A LA PRODUCTION, ET LA CONCENTRATION DE FIBRES EST MESUREE PAR EXEMPLE PAR L'INTERMEDIAIRE DE LA PUISSANCE DU MOTEUR DE LA POMPE, OU PAR UN DISPOSITIF25 DE MESURE DE LA CONCENTRATION, LE SIGNALQ DE MESURE AINSI OBTENU ETANT ENVOYE A UN DISPOSITIF28 DE REGULATION DE LA VITESSE DE LA MACHINE A PAPIER, EN VUE D'OBTENIR UN GRAMMAGE SENSIBLEMENT CONSTANT, LE SIGNAL DE MESURE ETANT ENVOYE A UN DISPOSITIF POUR COMMANDER LA TENSION29 DE REFERENCE DE LA MACHINE A PAPIER. INDUSTRIE DU PAPIER.DEVICE FOR ADJUSTING THE GRAMMAGE IN PAPER MACHINES. THE FLOW RATE OF THE SUSPENSION IS SET TO A VALUE WHICH IS PROPORTIONAL TO THE PRODUCTION, AND THE FIBER CONCENTRATION IS MEASURED FOR EXAMPLE VIA THE PUMP MOTOR POWER, OR BY A CONCENTRATION MEASURING DEVICE25, THE MEASURING SIGNAL THUS OBTAINED BEING SENT TO A DEVICE28 REGULATING THE SPEED OF THE PAPER MACHINE, IN ORDER TO OBTAIN A SENSITIVELY CONSTANT GRAMMAGE, THE MEASUREMENT SIGNAL BEING SENT TO A DEVICE FOR CONTROLLING THE REFERENCE VOLTAGE29 OF THE MACHINE PAPER. PAPER INDUSTRY.
