In an apparatus and method for manufacturing an automotive beam for use as a beam in structural components of automobiles, the beam is provided with significant improvements in terms of torsional rigidity and yield strength. The beam improves the overall safety of passengers and maintains the simplicity of the manufacturing process. The apparatus ( 1 ) for manufacturing roll formed profile beams comprises a plurality of material dispensers ( 2,6 ), a first set of rollers ( 5 ), a second set of rollers ( 11 ), a first welding station ( 10 ) mounted between the two sets of rollers ( 5, 11 ) and a second welding station ( 12 ) at the outlet of the second set of rollers ( 11 ). The method of manufacturing roll formed profile beams comprises the steps of roll forming a first profile element followed by roll forming a second profile element enclosing the first profile element and forming a closed profile beam having an internal support structure.
