ABSTRACT:
A method and apparatus for manufacturing metal profile members of open or closed construction, especially steel profile members, wherein a continuous band-like metal material of uniform wall thickness as viewed in cross-section is continuously fed along a path where it is continuously deformed by cold- and hot-shaping procedures to produce the profile member. The profile member produced in accordance with this process has one or more differences in wall thickness at one or more predetermined points in its cross-sectional width. During the hot-shaping procedure, at least one predetermined portion of the cross-sectional width of the band-like material is heated to soften that portion after which the band-like material is passed between pairs of discs disposed on opposite sides of the heat-softened portion, the angle of the discs relative to the band-like material being adjustable to cause the heat-softened area to be stretched or compacted.
