A mobile metal building forming machine (30, 34, 38, 40, 68, 74) forms a panel (P) of predetermined length from a coil of flat metal and then the formed panels are continuously crimped on their side edges (C s) for strength and are selectively curved by crimping the bottom (C b) of the panel. The crimping and curvature are automatically controlled so that building panels with vertical walls and an arched roof may be formed. A moveable crimping roll (70, 72) is automatically portioned to control the curvature and the roll is chain driven (94, 98, 102) so that it may be moved without affecting its rotational drive.
