Abstract:
1. An apparatus for manufacturing roll formed profile beams comprising: (a) a first material dispenser for dispensing a first material; (b) a first set of rollers having an inlet in communication with the first material dispenser to receive the first material being dispensed therefrom, the first set of rollers being adapted to form the first material into a first profile element having a predefined cross-sectional profile; (c) a second material dispenser for dispensing a second material adjacent the first material at an outlet of the first set of rollers; (d) a first welding station for welding the first material to the second material adjacent thereto; (e) a second set of rollers for receiving the welded first and second materials from the first welding station, the second set of rollers being adapted to form the second material into a second profile element having a predefined cross-sectional profile which encloses the first profile element; and (f) a second welding station in communication with an outlet of the second set of rollers for welding portions of the second material together as the welded first and second materials exit from the outlet of the second set of rollers to form a closed profile beam.
