Abstract

DISPOSITIF DE DOSAGE DE LIQUIDE DANS UNE ZONE DE PINCEMENT ENTRE LES SURFACES ADJACENTES D'UN ROULEAU DOSEUR ET D'UN ROULEAU DE TRANSFERT D'UNE MACHINE A IMPRIMER. LE DISPOSITIF COMPREND DES MOYENS PERMETTANT D'APPLIQUER DU LIQUIDE SUR UNE SURFACE DE L'UN DES ROULEAUX 50 OU 60 DE MANIERE QUE LE LIQUIDE SOIT TRANSFERE PAR LA SURFACE DU ROULEAU DANS LA ZONE DE PINCEMENT; ET DES MOYENS DE COMMANDE PERMETTANT DE DEPLACER L'UN DES ROULEAUX PAR RAPPORT A L'AUTRE ROULEAU ENTRE UNE PREMIERE POSITION OU UNE PRESSION DE CONTACT EST APPLIQUEE A L'EXTREMITE DES ROULEAUX ADJACENTE A LA ZONE DE PINCEMENT POUR DOSER LE LIQUIDE DANS LA ZONE DE PINCEMENT, ET UNE SECONDE POSITION OU L'UN DES ROULEAUX EST DISPOSE PAR RAPPORT A L'AUTRE ROULEAU DE MANIERE A PERMETTRE UN GLISSEMENT ENTRE LES SURFACES SECHES DES ROULEAUX SANS PROVOQUER DE DEGATS AUX SURFACES DES ROULEAUX TOUT EN CONTROLANT LE LIQUIDE QUI PASSE DANS LA ZONE DE PINCEMENT. APPLICATION : MACHINES A IMPRIMER.DEVICE FOR DOSING LIQUID IN A PINCH ZONE BETWEEN ADJACENT SURFACES OF A DOSING ROLLER AND A TRANSFER ROLLER OF A PRINTING MACHINE. THE DEVICE INCLUDES MEANS FOR APPLYING LIQUID TO A SURFACE OF ONE OF THE ROLLERS 50 OR 60 SO THAT THE LIQUID IS TRANSFERRED THROUGH THE SURFACE OF THE ROLLER INTO THE PINCH ZONE; AND CONTROL MEANS ALLOWING TO MOVE ONE OF THE ROLLERS RELATIVE TO THE OTHER ROLLER BETWEEN A FIRST POSITION WHERE CONTACT PRESSURE IS APPLIED TO THE END OF THE ROLLERS ADJACENT TO THE PINCH ZONE TO DOSAGE THE LIQUID IN THE ZONE PINCH, AND A SECOND POSITION WHERE ONE OF THE ROLLERS IS ARRANGED IN RELATION TO THE OTHER ROLLER SO AS TO ALLOW SLIP BETWEEN THE DRY SURFACES OF THE ROLLERS WITHOUT CAUSING DAMAGE TO THE SURFACES OF THE ROLLERS WHILE CHECKING THE LIQUID PASSING THROUGH THE PINCH ZONE. APPLICATION: PRINTING MACHINES.
