Abstract

The invention relates to a device for clamping hollow profiles, for example for the purposes of bending, wherein a support mandrel is arranged on the end of a retainer bar within the hollow profile with a mounting rod for a support core surrounding the retainer bar. A clamping jaw encloses the hollow profile in the region of the support core such that the profile is clamped between the support mandrel and the mounting rod with the support core to one side and the clamping jaw.
