Abstract
Appareil à former des emboîtures comportant un mandrin expansible s'emboîtant dans un tube dans lequel on veut réaliser une emboîture, constitué d'une pluralité de segments maintenus élastiquement entre eux et pourvu d'un passage axial de section conique ou pyramidale dans lequel pénètre une aiguille également conique ou pyramidale pour provoquer l'expansion radiale du mandrin. Selon l'invention, cet appareil est caractérisé en ce que la section de ladite aiguille est plus large du côté du tube que du côté de l'appareil et en ce qu'il comporte des moyens pour rétracter ladite aiguille vers l'appareil. Réalisation d'emboîtures dans des tubes, notamment pour plomberie.
