Abstract

An angular metal section is produced by rolling a rectangular elongate metal blank to form a lengthwise triangular ridge having an apical angle equal to that at which flanges of the section are to be set with respect to each other, and bending portions of the blank about this apical angle to form the flanges. The triangular ridge is formed by rolling from a rounded protuberance previously rolled on the blank. In each rolling pass, the thickness of the blank is reduced by about one third. In an additional optional pass to which the blank is subject before it is bent, the corners thereof exclusive of those bounding the surface carrying the triangular ridge are rolled to effect rounding thereof. <IMAGE>
