Abstract

Procédé de façonnage d'objets annulaires tels que des anneaux décoratifs. Le procédé de façonnage d'objets annulaires dans lequel une partie de la matière est disposée radialement par rapport à l'axe consiste à réaliser des pièces cylindriques sans fin à partir de bandes dont les extrémités sont soudées et dont la matière est orientée axialement, puis à déplacer une partie située entre les bordures annulaires internes radialement vers l'extérieur pendant que la périphérie de la pièce n'est pas supportée. Lorsque la totalité de la matière de l'objet terminé qui est située dans ses bordures doit être orientée radialement, les bordures annulaires internes ne sont pas supportées. Application à la production de garnitures annulaires décoratives de roues d'automobiles.
