Abstract

Dispositif réalisant le procédé de fusion de matière plastique comportant un corps rotatif 4 sur lequel sont disposés des canaux d'amenée ouverts du côté de l'apport de matière à traiter qui alternent avec des canaux d'évacuation ouverts du côté de la sortie, ces canaux étant obtenus sur le tronçon opérateur de fusion 6, disposé sur le corps rotatif 4 par des premières nervures 13, longeant la paroi intérieure du boîtier 1, ces premières nervures étant flanquées de deuxièmes nervures 14, sensiblement parallèles aux premières, lesquelles, avec un certain jeu, pour la masse non fondue, peuvent longer, plus ou moins près, cette paroi, des coudes 10, 16 étant prévus reliant alternativement les extrémités des premières et deuxièmes nervures sur les côtés de l'admission et de l'évacuation.
