Abstract

Machine perfectionnée d'extrusion-soufflage avec moule en deux parties caractérisée en ce que chacune des deux parties unitaires du moule creux présente deux jeux d'empreintes 11-12 et 16-17, sensiblement symétriques par rapport à un axe, espacés entre eux d'une distance A égale au pas de déplacement du porte-moule : le premier jeu d'empreintes 11-12 étant destiné à recevoir la paraison et à former l'ébauche lors de l'opération de moulage soufflage-refroidissement, le second jeu d'empreintes 16-17 étant en outre équipé des moyens de décarottage 18 à 21, 27 et 30 des déchets et des bavures formés sur l'ébauche réalisée.
