Abstract
The present invention is directed to a forming device adapted to impart a precise arcuate curvature to a sheet metal blank. The device includes a forming drum and a compression roller in proximate space relation to the surface of the drum. A characterizing feature of the device resides in a resilient deformable metal sheet having a lead surface fixed to the drum, the metal blank to be formed being captured between the drum surface and the flexible metallic sheet. Both the blank and the sheet are caused by the compression roller to conform to the curvature of the surface of the drum.
