  • Patent number: 8056382
    Abstract: The pressures provided by several wheels or rollers (18, 20, 22, 24, 30, 32) on various members of a metal panel are controlled to produce a curved panel of desired radius with little or no distortion. Predetermined pressures are used to achieve the desired curvature and increased pressures provide smaller radii of curvature. For metal ā€œUā€ panels pressure is preferably applied on two members. For seamed metal panels pressure is preferably applied on three members. Additional curvature may be obtained by use of a curving bar (82). Motors (34, 36, 38) drive the wheels, which urge these panel members through the wheels, the wheels having a separation distance less than the original thickness of the metal. This results in the metal of those members being elongated, thereby curving the panel with little or no distortion. Repeatable results are also provided.
