ABSTRACT:
A roll forming device receives a continuous elongated flat sheet of metal to form selected profiles along at least one longitudinal margin thereof. The roll forming device comprises a drive assembly, located within the apparatus frame which engages the elongated sheet proximate to the entryway and advances the sheet in a downstream direction discharge it at an exit. Preferably, at least one guide bar is supported by the frame which also engages the longitudinal margin of the sheet as it is advanced downstream and bends it into a trough-shaped cross-section. The frame houses at least one forming station having a coacting pair of first and second forming rollers journaled for rotation about respective axes. Some of the forming stations may include a plurality of pairs of coacting first and second forming rollers, at least some of which are mounted to be adjustably positioned toward and apart from one another to accommodate varying widths of sheet metal. Optional features may include a rotatable reel assembly operative to mount and feed a continuous coil of material, and a sub-frame for supporting an assemblage of forming stations which is adjustable in three dimensions.
