METHOD AND DEVICE FOR BENDING PROFILES WITH A VARIABLE CROSS-SECTION

A method for bending profiles, wherein the profiles have a profile web and bent or angled profile legs at lateral ends of the profile web, wherein the profile is bent or formed parallel to and in the plane of the profile web and the height of the profile web between the profile legs varies over the length of the profile. The profile is formed with a roll arrangement that has at least one supporting roll, one bending roll, and one forming roll positioned one after the other in the movement direction, wherein the supporting roll, the bending roll, and the forming roll rest against the profile or profile legs in lateral edge regions, and through the adjustment of the distance between the bending roll and the forming roll perpendicular to the movement direction of the profile, it is possible to adjust the bending radius of a profile.
