Method for smoothing the surface of bar material

摘要

A method and apparatus for smoothing local unevenness from the surface of bar material, such as anode bars, consisting of clamping the bar rigidly against a supporting frame and moving a smoothing device along the bar, said smoothing device maintained in continued contact with the bar by means of rollers pushing against opposed parallel faces of the bar. The rollers allow the smoothing device to move according to the general contour of the bar, so that only local unevenness is removed, and excessive smoothing due to curvature in the overall bar length is eliminated.
