Abstract

CE DISPOSITIF EST DESTINE A INTERCHANGER RAPIDEMENT LES TAMIS SERVANT A LA FILTRATION DE MATIERES A L'ETAT PLASTIQUE. IL COMPREND UNE MONTURE DE TAMIS 4 PRESENTANT UN TROU ALESE POUR LA MATIERE QUI PASSE ET UNE FENTE 12 QUI S'ETEND PERPENDICULAIREMENT A CE TROU ET DANS LAQUELLE DES PORTE-TAMIS 5 PORTANT DES TAMIS 6 SONT MAINTENUS DE MANIERE ETANCHE EN POSITION OPERATOIRE. AU MOYEN D'UN CYLINDRE DE MANOEUVRE 9, CHAQUE TAMIS ENCRASSE PEUT ETRE EXPULSE ET REMPLACE PAR UN TAMIS IMMEDIATEMENT SUIVANT, SANS INTERRUPTION DU TRANSPORT DE LA MATIERE. LE DISPOSITIF CONVIENT PARTICULIEREMENT BIEN POUR ETRE INCLUS DANS UNE EXTRUDEUSE SERVANT A LA FABRICATION DE CHAMBRES A AIR POUR PNEUMATIQUES D'AUTOMOBILES, AUQUEL CAS IL EST INTERPOSE OPPORTUNEMENT ENTRE L'EXTRUDEUSE ET SA TETE D'EXTRUSION.
