Abstract
In a method of manufacturing a curved and quenched profile element, a profile element is positioned in a die tool with relatively movable tool halves for forming the profile element into a desired curved shape. The profile element is pushed between the tool halves thereby heating the profile element to a quenching temperature and forming it into the desired curved shape. Heat is dissipated from the curved profile element at an elevated cooling device whereat a cooling liquid flows through the die tool while the profile element is still contained therewithin. The profile element is transported in a forward direction along a manufacturing path to the cooling device and is transported in the same forward direction to remove it from the cooling device thereby providing continuous mechanical handling of the profile element during the manufacturing process. The tool halves each have a facing side provided with alternating ribs and grooves so that the grooves can function as channels to lead the cooling liquid to the curved profile element.
