Abstract

A method of forming sharp-edged profiled rails and bodies from metal bands. A band is first corrugated, and a directrix is determined subdividing the band into first and second areas composed of the areas between the first and second exterior edges of the band and the directrix. One of the areas is moved in a swinging motion about the directrix while the transverse distance of the associated exterior edge of the area from the directrix is reduced during each part of the continuous forming process. By continuously reducing this transverse distance accrued edge tensile stresses are reduced. The initial corrugations formed in the band are increased so that the length of each envoloping line of each part of the band is longer than the enveloping line of the longitudinal profile contemplated for the corresponding part by about 2-5 percent. This allows subsequent upsetting and bending of the band with a curvature smaller than the band thickness without any thinning or weakening at the bends. Profiled rails formed in this manner may then be connected to form profiled bodies in a variety of ways.
