Abstract (en)
[origin: EP0695591A1] The machine comprises a bending die (2), at least one clamp (3) and slider (4). There is at least one transfer member in continuous content of the hollow profile (6) inner side walls, or their grooves over their entire surface, which it also supports. The transfer member consists of pressure-resistant, elastic material. Pref. two opposite transfer members are used. They are in contact with the envelope faces of calibrating rollers (37), located between the transfer member. The transfer members may be made of spring steel. The calibrating rollers may be threaded on a flexible wire rope of large tensile strength.
