Abstract

Procédé et appareil pour dilater l'extrémité d'un tube en matière plastique pour y former une cloche après chauffage du tuyau à une temperature prédéterminée. L'appareil comprend un mandrin muni d'une base et d'un noyau cylindrique traversés par un passage longitudinal. Le noyau comporte des gorges annulaires communiquant avec ledit passage qui est relié à une source de vide; une coquille segmentée formée de plusieurs pièces et fixée sur le noyau du mandrin, cette coquille comportant plusieurs ouvertures alignées avec les gorges formées sur le noyau. Dès que le tuyau chauffé est dilaté sur la coquille, on fait le vide pour aspirer la paroi interne du tuyau contre la surface externe de la coquille. Fabrication de tuyaux raccordables entre eux.
