Abstract

L'invention concerne un procédé de cintrage de deux tubes insérés l'un dans l'autre avec un espacement radial entre eux, sur une cintreuse à tubes comportant un chariot d'avance muni d'un manchon de serrage et une table pivotante munie d'un gabarit de cintrage, d'une mâchoire de serrage pouvant aller et venir relativement au gabarit et d'une glissière. Le procédé selon l'invention est remarquable en ce qu'il consiste pour le cintrage, dans la région du gabarit de cintrage, du côté tourné vers le gabarit, à amener le tube intérieur à s'appliquer contre le tube extérieur et à introduire un mandrin dans le tube intérieur et un mandrin entre le tube intérieur et le tube extérieur du côté opposé au gabarit et tourné vers la mâchoire de serrage. L'invention concerne également un appareil pour la mise en oeuvre de ce procédé.
