Apparatus and method for forming compound shaped surfaces

摘要

Apparatus and method for forming compound shaped surfaces. A skin conforming to the visual shape of the surface being formed is prepared from a blank sheet of material that is cut to size and includes any desired stamped-out detailing or notched edges or lines. Disposable strips of material are used to form hems in the skin. A preforming die is used to create tight bends or outer contours in the skin. A liner of the desired size and detailing is formed along with two-shaped side flanges. A plurality of ribs or silhouettes are provided and placed into the skin to form and maintain the desired final shape. The pre-formed liner is then assembled to the skin, the ribs being disposed between the liner and the skin.
