         The method of circular bending is to add a set of three-roll circular bending mechanism at the end of the forming unit.In the case of continuous forming, the curved round roll is usually not driven.In order to avoid or minimize the profile warping between the last forming roller and the bending roller, the two rollers should be installed as close as possible.Another method that can be used is to use a support device around the profile to avoid wave-forming.During the design phase, consideration must be given to removing the end of the profile from the unactuated round bend.
