Abstract

Appareillage de thermoformage. Cet appareil comporte un mandrin chauffé, une cavité de moulage, des moyens pour maintenir la feuille de matière thermoplastique chauffée en position entre le mandrin et la cavité du moulage, et il est caractérisé par le fait qu'au-dessus de la cavité de moulage est positionne un guide à cavité en forme de dôme, dont le diamètre est supérieur à celui de la cavité de moulage, ce guide étant pourvu d'un insert faisant office de couteau. Permet la fabrication d'articles creux à partir de feuilles en matière thermoplastique.
