Abstract (en)
[origin: WO2004101190A1] The invention relates to a method and a device for bending a standing-seam sheet metal section (2) that is supplied in a web, said section comprising an essentially flat connecting piece (3) with a flange (4, 5) on either side, said flanges being on a plane that is perpendicular to that of the connecting piece (3), thus forming a U-shaped section. According to the invention, to bend a standing-seam sheet metal section (2), whose connecting piece (3) tapers in the longitudinal direction, the mobile support (9) comprising mounted rollers (12a, 13a, 14-16, 18) is pivoted in accordance with the angle of conicity of the sheet metal web (2) in relation to the web transport direction and the rollers (10a, 10b, 11b, 14-17) on the other side of the web transport path and during the progression of the sheet metal web (2) the mobile support (9) is driven in a controlled manner transversally to the web transport direction (X), so that it adapts to the changing web width of the sheet metal web (2).
