Abstract
An apparatus and process for reducing variations in the profile of a sheet metal stock are shown and described. The process includes the use of two passes, each comprising two smoothing surfaces. The smoothing surfaces of each pass are mateable to define a profile between the smoothing surfaces. The profile defined between the smoothing surfaces of the first pass is substantially the inverse of the profile defined between the smoothing surfaces of the second pass. As a sheet metal is processed between the first and second passes, it is formed with the first profile and the second profile thereby reducing variations in the profile of the sheet metal.
