Zusammenfassung:	A method for producing a metallic formed hollow profile which is curved in at least one axis, in which a hollow metallic profile element is formed by means of two tool elements of a tool group which hold a cross section part of the hollow metallic profile element, on a length of the hollow metallic profile element, wherein at least two tool groups each having two tool elements which are spaced from one another are provided, wherein each of the tool groups is fixed to the hollow metallic profile element at least in regions in a forced based manner, wherein the region of the hollow metallic profile element to be formed is arranged between the tool groups, and wherein through relative movement of the tool groups to one another, the hollow metallic profile element in the freely arranged region located between the tool groups is formed at least partially.
