Abstract (en)
[origin: WO2005002753A1] The invention relates to a method for producing hollow profiles provided with different cross sections along the length thereof. Said profiles are shaped in a die from one piece of cut metal sheet (5, 6, 7). According to said invention, a convex or concave rounding produced on the edges of a longitudinal section (8a, 8b, 9a, 9b) results in material excess or material shortage in the transition regions (8, 9), thereby preventing the material thinning or thickening in said transition regions (8, 9) during forming.
