Abstract
The invention relates to a method and device for producing metal sections having two profile flanges arranged opposite one another and having flange inner faces that are to be kept apart from each other by a closely toleranced final chamber dimension. In order to adapt the chamber dimension from a starting chamber dimension K0 to a desired final chamber dimension K1, the metal section is passed through the device, which forms working gaps between an inner working roll pair and outer support rolls. The working rolls that form the inner working roll pair roll over each other in order to brace the forming forces exerted on the working roll pair from the flange inner faces against each other.
