Title: Apparatus and method for forming metal building panels

Abstract: Apparatus and method for crimping the side walls of a sheet metal building panel independently of a main crimper which crimps the belly of the panel. The depth and the position along the panel of the side crimp is adjusted independently of the main crimpers in relation to the radius the panel is being curved and the length of panel that has passed through the apparatus. The adjustment is controlled by a microprocessor. The microprocessor controls a hydraulic motor which drives a machine screw which activates a scissors-jack type linkage. Blocks holding the rotatably mounted crimping rollers are mounted on slides and attached to the linkage. As the linkage moves, the depth of the crimping rollers is adjusted. The rotation of the crimping rollers is hydraulically driven through a gear-sprocket rotary motion drive train.
