  • Method and Apparatus for Manufacturing Asymmetrical Roll-Formed Sections
    Publication number: 20140150513
    Abstract: A roll-forming station for forming asymmetrical sheet metal beams with unequal flanges, where both of the unequal flanges contact the rolls simultaneously and where the diameters of the rolls are such that the bending moments applied to the unequal flanges are identical in magnitude. This prevents lateral displacement of the workpiece during forming.
