Fremgangsmåde til fremstillingen af et koldvalset profil med mindst én fortykket profilkant

摘要

A method for the production of a cold-rolled profile having at least one thickened profile edge made of a metal strip is provided. For this purpose the metal strip is guided through at least one clamping nip formed by at least one guide roll and at least one lateral edging roll, wherein the roll axis of the guide roll is disposed parallel to the web level of the metal strip, while the roll axis of the edging roll is disposed transverse to the roll axis of the guide roll, and is lined up at an angle to the strip level such that in addition to the upsetting force exerted by the edging roll onto the strip edge a clamping force is also applied that acts on the side of the metal strip facing away from the guide roll. The edging roll may be configured in steps, and surrounds the web edge at least on the side of the metal strip facing away from the guide roll.
