A roll bender is a mechanical jig having three rollers used to form a metal bar into a circular arc.

The rollers freely rotate about three parallel axes, which are arranged with uniform horizontal spacing. The two outer rollers have the same fixed vertical height and make contact with the underside of the bar to be formed. The middle roller has an adjustable height and makes contact with the topside of the bar.
