Abstract

Procédé pour maintenir propres les plaques à trous ou à filières dans l'extrusion de matières polymères pouvant être mises en forme à partir de la masse fondue, en particulier procédé pour éviter les dépôts au voisinage des embouchures des filières par gazage de ces ouvertures de filières à la sortie de la masse fondue, caractérisé en ce que le gaz consiste totalement ou partiellement en des vapeurs de substances qui exercent un processus de dégradation au bord des filières sur les dépôts provenant de la masse fondue.
