Abstract (en)
[origin: WO2011141336A1] The invention relates to a method for producing hollow profiles having a longitudinal flange, wherein a blank disposed between a punch and a first die is preformed into a U-profile having a first limb and a second limb by driving a punch into a first die, and wherein the U-profile is formed into an O-profile having a longitudinal flange by means of a second die. The aim of disclosing a reliable method for producing hollow profiles having a longitudinal flange and allowing better control of the dimensions and shape of the longitudinal flange is achieved in that a longitudinal flange limb segment is formed in at least the first limb when preforming the blank into the U-profile, and the longitudinal flange limb segment is formed into a part of the longitudinal flange while substantially retaining the shape thereof during the forming of the U-profile into an O-profile.
