Date Dec. 17, 1987.In the process for the cold forming of ferrous and nonferrous metal sections, pretensioning is applied to the initially essentially straight metal section, which is clamped at both ends. Next, the tensioned metal section is bent in a rotating bending tool. In order to achieve three-dimensional forming of the metal section, the bending tool effects a controlled movement in all three spatial axes, whereby the metal section is pressed, with a backlash-free guide system, at least in the forming region against the bending tool and guided by positive engagement.
