A microprocessor controlled apparatus and method for processing sheet material into building panels (P) for assembly into buildings. The sheet material is formed into a panel (P) having a flat bottom and sides while length of the formed panel is monitored to control the operation of the forming device. The panel is then fed into a curve-forming device (68) which crimps at least a portion of the panel so that it is arched or curved. The curvature of the output panel (Cb) is monitored (74) to control the location of adjustable crimper rollers (70, 72) disposed in the curve-forming device (68) to provide the portion of the panel with an accurate preselected curvature. The length of the curved portion of the panel is monitored (58) when producing panels having both straight and curved portions, and the crimper rollers (70, 72) automatically reset to form portions with a different radius of curvature.
