ABSTRACT:
A method and apparatus for forming structural members from a substrate heats a middle portion of the substrate in combination with edge guide rolls for laterally displacing mass of the substrate. Top and bottom rolls shape the structural member into the desired shape. The entire substrate is annealed. Thereafter, additional roll passes can be used for improving the shape of the substrate to the desired shape.
