Abstract

La présente invention est relative à un dispositif de cintrage des bords de flans en tôle de grande surface. Dans un dispositif selon l'invention, le flan 10 incurvé à l'avance est immobilisé sur un support 12 par un vérin 24. Un outil de cintrage mobile 30, porte par un support équilibré, se déplace le long du bord en cintrant le bord en le pressant contre un support ou une enclume avec des pièces de formage formant un ensemble non plan, actionné par vérin. Application à la fabrication de réservoirs soudés de grandes dimensions.
