ABSTRACT:
Methods for forming a soft lip for a wheel rim are disclosed herein. The wheel rim may be a cold-formed, spun-formed, or rolled-formed cylindrical blank, wherein the blank includes an upturned outer edge. As the blank is spun, a blunting roller lowered to contact the upturned outer edge to blunt the outer edge into a work-strengthened annular bead, and finish off the external surface of the annular bead to form a soft lip.
