Abstract

L'INVENTION CONCERNE LA PRODUCTION CONTINUE D'UNE MOUSSE DE POLYURETHANNE A L'AIDE D'UN MOULE 10 A SOMMET OUVERT ET DONT LES PAROIS 20, 23, 23A SE DEPLACENT. UN MELANGE FLUIDE DE CORPS DONT LA REACTION FORME UNE MOUSSE DE POLYURETHANNE, EST DEPOSE EN 11, SOUS FORME D'UNE MASSE A MOUSSAGE PREALABLE ET DILATATION PARTIELLE, PRES DU SOMMET DU V FORME PAR LES PAROIS LATERALES 14, VERTICALES ET DIVERGENTES, DE LA PREMIERE PARTIE 12 DU MOULE. LA LEVEE DU MELANGE EST QUASI-TOTALEMENT ACHEVEE LORSQU'IL ATTEINT LA PARTIE 13 DU MOULE A PAROIS LATERALES 15 PARALLELES. DES BANDES SE DEPLACENT LE LONG DES PAROIS LATERALES EN 23, 23A ET LE LONG DU FOND 20 DU MOULE. APPLICATION: COULEE EN CONTINU D'OBJETS DE SECTION RONDE OU CIRCULAIRE POUR LE REMBOURRAGE OU L'ISOLATION THERMIQUE.
