Abstract

L'invention concerne un procédé de préparation d'une ébauche tubulaire matricée ou coulée à paroi épaisse 1, pour un tirage en cascade venant ensuite. A cette fin, il est proposé que l'ébauche tubulaire 1 soit élargie à une extrémité à l'aide d'un mandrin captif (3), puis soit étirée extérieurement, dans la zone élargie (7), au moyen d'une filière d'étirage (2) coopérant avec le mandrin captif, la zone étirée étant guidée passant dans la direction d'étirage au moyen d'une filière d'étirage et étirée avec utilisation d'un mandrin captif, élargissant intérieurement.
