ABSTRACT:
An elongated workpiece is passed along an arcuate path defined by a pair of end rollers flanking a middle roller. At least one of the rollers is formed with a workpiece-receiving groove having flanks at least one of which has a milling formation for removing ridges that form on a workpiece passing along the arcuate path between the rollers. Thus, these ridges that form inherently on a workpiece that is bent are removed during the bending thereof to prevent the workpiece from jamming in the bending rollers.
