Patent number: 6988390Abstract: A method of forming a tubular workpiece which consists in pre-bending a metal plate along at least two longitudinal lines of bend (12–13) then in bending the plate along at least one of the lines of bend (12–13) using a bending member (103–104) that exerts an external clamping force (F7, F8) along a part (23, 24) of the plate towards the at least one of the lines of bend (12, 13). Thereby preventing any sliding of part (23, 24) of the plate along the bending member (103–104) as the bending member bends the part. The bending member is articulated about a virtual geometrical axis (a, c) located inside a tubular section of the workpiece.Type: GrantFiled: September 25, 2001Date of Patent: January 24, 2006Assignee: Imphy AlloysInventors: Jean-Claude Jeandeaud, Jean-Pierre Reyal
