Abstract:
An apparatus and method for forming a conical flange about a circular opening in a malleable sheet material are provided. A plurality of flange-forming members are adapted to engage the circular opening in a material-opposing relationship. The members are then translated about the opening while maintaining the material-opposing relationship and varying the angular positions of the flange-forming members with respect to the material such that the conical flange is formed therein when the members are translated.
