Abstract

The invention relates to a procedure for cold bending of profiles (3), especially wide-flange beams, in particular to form S-shaped railway sleepers, while maintaining the cross-sectional shape of the profile, in which - the profile (3) is clamped between a first pair (1) and a second pair (2) of jaws situated at a distance from one another, - the second pair (2) of jaws is then displaced over a section of a circular arc (29), the centre of which is close to the first pair (1) of jaws, - during the displacement, the second pair (2) of jaws maintains its parallel alignment relative to the first pair (1) of jaws and - the profile section (3a) lying between the pairs (1, 2) of jaws pulls the second pair (2) of jaws onto the circular arc (29). <IMAGE>
