Abstract

L'invention concerne une machine et un procédé de traitement de matières plastiques ou polymères particulaires liquéfiées en cours de traitement. Ladite machine comporte un élément 38 constituant une surface de retenue de la matière particulaire et un élément 32 constituant la surface 34 collectrice de matière liquide et l'un ou l'autre de ces éléments ou les deux présente un tronçon se prolongeant vers l'autre élément et occupant une partie prédéterminée d'un espace réservé à la matière liquide pour délimiter un espace secondaire, de forme géométrique prédéterminée choisie pour imposer une pression de décharge présélectionnée à la matière liquide rassemblée sous forme d'une masse en vue de sa décharge. Application au traitement de matières plastiques ou polymères particulaires à liquéfier au cours de leur traitement.
