An electric rollforming unit from Lamb Technicon Body Assembly Systems, a UNOVA Co., Warren, MI, helps ensure the efficient assembly of highly contoured automotive exterior panels.The unit takes difficult-to-hem, open-angled flanges that often result from the stamping of complex automotive closure panels, then quickly and precisely them to a hem-mable angle through a single-point roller. The roller's precise contact enhances hem and panel surface quality, in addition to bending the flange to a workable hem angle.
