Roll Forming Roll-formed profiles often go out of specification during a run because the incoming coils have lot-to-lot variations in width, thickness, crown, camber, and physical properties. Manual inspection is a time-consuming method to isolate out-of-specification material, resulting in bad parts produced on long runs. Fea tures • Monitor key dimensions in-line for changes due to coil thickness, crown, camber, and physical properties • Reduce or eliminate costly and time-consuming off- line checking • Make faster set-ups by checking each pass on-line 533 L aser M easurement
