Abstract

Dispositif de moula flexibles utilisés dans la fabrication d'objets à partir d'une paraison tubulaire en matière plastique. Ce dispositif est constitué par deux ensembles de demi-moules complémentaires montés sur deux chaînes sans fin, entre lesquels est extrudée en continu une paraison tubulaire. Des plaquettes transversales rigides sont insérées dans chaque demi-moule. Ces plaquettes comportent des interstices faissant communiquer l'intérieur avec l'extérieur du moule et permettant ainsi de transmettre à l'intérieur une dépression effectuée à l'extérieur du moule. L'invention est utilisée pour la fabrication en continu d'objets creux par expansion d'une paraison tubulaire contre les parois de moules se déplaçant en cycle fermé.
