Abstract: In a press bending arrangement for an aluminum profile, especially for manufacturing the equator profile for an LNG-tank, the press is connected to control and measuring devices in such a manner, that the reflection of the workpiece is taken into account both in bending the profile and in determining the bending control based on measurements being made.
