Patent ID: 7677071

Claim:
An apparatus for roll forming metal components including substantially channel-shaped members for use in a building structure, said apparatus comprising: a support frame assembly having front and rear portions; a mechanism for selectively feeding at least one metal strip into said support frame assembly, said metal strip having a pair of side edges and a center web; a plurality of driver roll elements mounted along said support frame assembly and adapted to move the metal strip through said frame assembly; and a plurality of spaced idler forming rolls mounted for free rotation in pairs along said support frame assembly and adapted to simultaneously air form the side edges of said metal strip into angularly extending side flanges by urging the side edges in opposing directions from said center web; and wherein said feeding mechanism is adapted to feed a pair of metal strips into said frame assembly, said metal strips having substantially congruent side edges and center webs, wherein said driver roll elements are adapted to move said paired strips substantially simultaneously through said frame assembly, and wherein said forming rolls simultaneously air form the side edges of said paired metal strips into angularly extending side flanges by urging the substantially congruent side edges of said paired strips in opposing directions from one another.
