Abstract

L'INVENTION CONCERNE UN DISPOSITIF DESTINE A RENDRE MOUSSANT UN LIQUIDE VISQUEUX. CE DISPOSITIF COMPREND UN ELEMENT METTANT SOUS PRESSION LE LIQUIDE ET LE REFOULANT VERS UN ORGANE D'APPLICATION QUI PRESENTE UNE CHAMBRE INTERIEURE 122 DANS LAQUELLE LE LIQUIDE S'ECOULE EN FORMANT UN COURANT CONTINU. DES CANAUX 125 DEBOUCHENT DANS CETTE CHAMBRE 122 ET Y INTRODUISENT UN GAZ SOUS PRESSION QUI PENETRE DANS LE LIQUIDE ET SE MELANGE AVEC LUI. LE MELANGE DE GAZ ET DE LIQUIDE AINSI OBTENU EST MAINTENU SOUS PRESSION JUSQU'A CE QU'IL ATTEIGNE L'ORIFICE 141 DE DECHARGE D'UNE BUSE 130, 140. DOMAINE D'APPLICATION : APPLICATION DE CORDONS D'ADHESIF SUR DES EMBALLAGES EN CARTON, ETC.THE INVENTION RELATES TO A DEVICE FOR RENDERING A VISCOUS LIQUID. THIS DEVICE INCLUDES AN ELEMENT PUTTING THE LIQUID UNDER PRESSURE AND DELIVERING IT TO AN APPLICATION UNIT WHICH PRESENTS AN INTERNAL CHAMBER 122 IN WHICH THE LIQUID FLOWS FORMING A CONTINUOUS CURRENT. CHANNELS 125 OPEN IN THIS CHAMBER 122 AND INTRODUCE A GAS UNDER PRESSURE THEREIN, WHICH PENETS INTO THE LIQUID AND MIXES WITH IT. THE MIXTURE OF GAS AND LIQUID SO OBTAINED IS KEPT UNDER PRESSURE UNTIL IT REACHES THE DISCHARGE PORT 141 OF A NOZZLE 130, 140. FIELD OF APPLICATION: APPLICATION OF ADHESIVE CORDS TO PACKAGING IN CARTON, ETC.
