<p>A method for the roll-forming of profiles or structural parts from semifinished sheet-like products, in particular from metallic materials, in particular from steel sheet or aluminum. For this, the semifinished sheet-like product is adjusted in its temperature, the adjustment of the temperature taking place locally, in particular in forming regions of the semifinished product that are intended to undergo a forming operation. Furthermore, a component is preferably produced by using this method, in particular a structural part for a seat structure of a motor vehicle, in particular a vehicle seat rail that can be adjusted forwards and backwards to adjust the seat, and to a roll-forming device for carrying out the method.</p> |
