Abstract
A process is provided for forming a metallic edge having a three dimensional internal configuration by preparing a metallic edge blank having a two dimensional internal configuration; attaching a flange to the sides of the blank; preheating the blank, forming mandrel and receiver dies to a temperature at which the metal is in a malleable state, with the forming mandrel having an external surface which corresponds to the three dimensional internal configuration of the formed metallic edge; and hot forming the metallic edge by securing the blank within the receiver dies and advancing the mandrel into the inner cavity of the blank through use of a drive means which rotates the mandrel as it advances into the blank while maintaining the blank, mandrel and receiver dies at the malleable temperature.
