Abstract

PROCEDE PAR LEQUEL ON INTRODUIT DANS UN MOULE EN ROTATION ET EVENTUELLEMENT EN PIVOTEMENT, TOUT D'ABORD, UNE MASSE DE MATIERE SYNTHETIQUE FONDUE DESTINEE A FORMER LA COUCHE EXTERIEURE DU CORPS MOULE FINAL, PUIS UNE AUTRE MASSE REMPLISSANT, PAR EXPANSION EN MOUSSE, LE CORPS CREUX FORME DANS LE MOULE. PROCEDE CARACTERISE EN CE QU'ON INTRODUIT D'ABORD UNE MASSE DE MONOMERE POUR FORMER LA COUCHE EXTERIEURE, PUIS UNE MASSE DE MONOMERE A MEME MATIERE DE BASE, MAIS POURVUE D'UN AGENT D'EXPANSION EN MOUSSE, LES DEUX MASSES ETANT SOUMISES DANS LE MOULE A UNE POLYMERISATION. PROCEDE APPLICABLE A LA FABRICATION DE CORPS MOULES LEGERS, MAIS RESISTANT AUX SOLLICITATIONS MECANIQUES.
