Abstract

CE STABILISATEUR CYLINDRIQUE PERMET DE TRAVAILLER SANS FLUCTUATIONS NI RUPTURE DE LA BULLE MEME DANS LE CAS OU LA VITESSE DE TRACTION DU FILM TUBULAIRE EST TRES GRANDE, LE REFROIDISSEMENT DE L'EXTRUDAT TUBULAIRE DE RESINE FONDUE SORTANT DE LA FILIERE INSUFFISANT OU LE DEBIT D'EXTRUSION DE LA FILIERE TROP GRAND, CE STABILISATEUR COMPREND UNE PARTIE CYLINDRIQUE 1 AU-DESSUS D'UNE BASE CONIQUE 2 RETRECIE VERS LE BAS. DES TROUS D'ENTREE 3 SONT PERCES DANS LA PARTIE CONIQUE, COMMUNIQUENT AVEC LA CAVITE INTERIEURE ET AVEC UN ORIFICE 4 DU SOMMET DU STABILISATEUR. LA SURFACE EXTERIEURE DE LA PARTIE CYLINDRIQUE 1 COMPORTE A LA FOIS DES DESSINS 11, COMPOSES DE CREUX ET DE BOSSES DONT LA DIFFERENCE DE HAUTEUR EST DE 0,1 A 0,5MM, ET UN OU PLUSIEURS SILLONS PROFONDS ET CONTINUS, QUI S'ETENDENT SUR TOUTE LA HAUTEUR DE LA PARTIE CYLINDRIQUE 1 ET POSSEDENT UNE PROFONDEUR DE 0,5MM OU PLUS,CES SILLONS ETANT PAR EXEMPLE CREUSES EN HELICE.
