Roll Bender

During the roll bending process the pipe, extrusion, or solid metal is passed through a series of rollers (typically no more than three). These rollers exert pressure on the pipes and thereby change the bend radius in the pipe. There are also pyramid style roll benders which utilize only a single moving roll, usually the top roll. There is another type of roll bender which is known as a Double Pinch type roll bender, which has two adjustable rolls, (usually the bottom two rolls), and a static top roll. This method of bending causes virtually no imperfections in the cross section of the pipe. The process of Roll Bending is usually suited to producing coils of pipe as well as long bends, most often used in truss systems.
