Abstract

Un procédé et un dispositif servent à produire des corps creux et volumineux à parois stratifiées en plastique. Afin de réduire le coût du procédé et de son contrôle, et d'obtenir un profil uniforme des couches formant la paroi stratifiée, plusieurs couches de matériau sont rassemblées à l'intérieur d'un piston annulaire radialement mobile de façon à former une masse fondue stratifiée. La masse fondue stratifiée s'écoule à l'intérieur du piston annulaire, se dilatant en entonnoir vers une chambre annulaire de stockage. Le piston annulaire est repoussé en arrière par la masse fondue, celle-ci étant extrudée à travers une filière par l'avancement du piston annulaire, formant ainsi un extrudat.
