Roll Bending Machines • Models 1212, 1618, 1824

Built to meet the demands of production involving small, light gauge parts. Pneumatic lock-up is standard on all models for increased productivity. 120V 1PH standard wiring simplifies installation. 220 or 440V 3PH wiring is also available.

The Two Roll Principle method is comprised of a steel top roll and a urethane bottom roll. A segment of this top roll is pushed into the urethane bottom roll, and this deflecting volume of urethane functions the same as hydraulic fluid in a hydroforming process, exerting very high pressures against the steel roll. When sheet metal is inserted between two such rolls, the urethane wraps the sheet metal tightly against the steel roll (similar to a radius forming urethane press brake die), and since the urethane roller is driven, the sheet metal is roll formed into a precise radius. Allowing for natural spring back of the material, this radius remains uniform irrespective of whether the shape of the part being formed is a complete circle, or is only a segment of a circle. The flat spots on the leading and trailing edges are very minimal (approx. one to four material thicknesses, depending on the type of material). Otherwise difficult-to-roll sheet metal parts, such as those with perforations, cut-outs, uneven feeding or trailing edges, embossed parts, ect. can be formed without kinking or fluting.
