Abstract
In order to provide a balanced bent lip disc, the applicant routinely had issues with rippling at an outer circumference edge of the lip. Due to the geometries involved in a 3½ inch disc bent to provide an outer lip of ½ inch at 45 degrees, 0.1145 of excess circumference is created thereby providing a ripple effect. The applicant discovered that simultaneously embossing the lip while bending the lip could reduce this rippling effect (and the outer circumference at the edge) by at least 75 if not 90 or 95% of a non-embossed lip bent in the same manner.
