摘要
The machine for bending hollow sections has a roller (1) with a circumferential groove and a support bar (6) to receive the section (3). The support bar (6) has a longitudinal groove which, together with the roller groove, fits closely aruond the outside surface of the hollow section. The roller (2) has a tangential arm (4) with a clamp (5) to receive one end of the hollow section. The size of roller (1) is chosen so that its radius is equal to the required radius of curvature of the bend in the hollow section. USE/ADVANTAGE - Hollow sections bending machine. Because the hollow section is firmly supported in the grooves of the roller and bar there is no deformation of the section walls.
