Abstract: Process and Device for the Manufacture of Frame Profile Elements for Windows, Doors, or the Like and of the Frame Profile Element manufactured Accordingly The invention relates to a process for the manufacture of frame profile elements (1) for windows, doors or the like from sheet metal or other material shapes (2, 3) designed, for example, as aluminum, wood or plastic shells and forming preferably opposing surface areas of the frame profile element (1), and a common solid profile core (4) that forms a positive and/or non-positive connection with said material shapes by means of forming and curing and is made of a rigid plastic foam such as polyurethane in which process the material shapes (2, 3) are embedded in a profile element production mould made, for example, of aluminum and the cavities that remain following their closure are filled with a rigid plastic foam. To provide a process and a device with which frame profile elements (1) for windows, doors or the like can be manufactured with non-warping and non-bending properties despite the deviating centroidal axes and without considering the shape and kind of material shapes (2, 3), it is provided that during the production process, the profile element production mould is bent is a direction opposite the expected warping of the frame profile element (1).
