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.THE INVENTION RELATES TO THE CONTINUOUS PRODUCTION OF A POLYURETHANE FOAM USING AN OPEN TOP MOLD 10 AND WHOSE WALLS 20, 23, 23A ARE MOVING. A FLUID BODY MIX, THE REACTION OF WHICH FORM A POLYURETHANE FOAM, IS DEPOSITED IN 11, IN THE FORM OF A MASS WITH PRIOR FOAM AND PARTIAL EXPANSION, NEAR THE TOP OF THE V SHAPED BY THE SIDE WALLS 14, VERTICAL AND DIVERGENT, OF THE FIRST PART 12 OF THE MOLD. THE LEAVING OF THE MIXTURE IS ALMOST COMPLETELY COMPLETED WHEN IT REACHES PART 13 OF THE 15 PARALLEL SIDE WALL MOLD. BANDS MOVE ALONG THE SIDE WALLS AT 23, 23A AND ALONG THE BOTTOM 20 OF THE MOLD. APPLICATION: CONTINUOUS CASTING OF OBJECTS WITH ROUND OR CIRCULAR SECTION FOR PADDING OR THERMAL INSULATION.
