Abstract

A.L'INVENTION CONCERNE UN DISPOSITIF DE REMPLISSAGE DESTINE A INTRODUIRE DES GRANULES DE MATIERE THERMO-PLASTIQUE PRE-EXPANSEE, EXPANSIBLE, DANS DES MOULES POUR FABRIQUER DES PIECES EN MOUSSE DE PLASTIQUE, EN PARTICULIER DES PIECES DE POLYSTYRENE EXPANSE, EN STYROPOR OU STYROZELL. B.CE DISPOSITIF EST CARACTERISE EN CE QU'IL COMPORTE UNE DOUILLE DE FERMETURE MOBILE QUI BLOQUE, AU MOYEN D'UN RACCORD L'ALIMENTATION EN GRANULES QUAND LE PISTON EST ARRIVE AU-DELA DU RACCORD D'ALIMENTATION DANS LA DIRECTION DU MOULE. C.CE DISPOSITIF PERMET D'ECONOMISER UNE CERTAINE QUANTITE D'ENERGIE ETOU D'ACCELERER L'OPERATION DE REMPLISSAGE, CE QUI DIMINUE LES FRAIS DE PRODUCTION.
