ABSTRACT:
A method and tool for forming a hem flange. A larger radius bend is initially formed when a pre-hem flange is formed. A sharper radius bend is subsequently formed when the flange is formed. After the flange is formed, conventional hem forming methods and tools may be used to complete formation of a hem that may be used to join inner and outer panels.
