Abstract: An apparatus for unfolding a rolled-up, elongate hollow body provides for stabilizing the unfolding body in a transition region. The hollow body has a closed cross-sectional profile. The unfolding mechanism has a winding core on which the hollow body is rolled up and compressed in a first state, and, by rotation, transfers the hollow body to an unrolled and unfolded second state. The hollow body is guidable between an outer fixing element positioned outside the hollow body and an inner supporting element which lies against an inner wall of the hollow body. The inner supporting element and outer fixing element interact in a form-fitting and/or force-fitting manner for axial positional fixing of the inner supporting element without a directed mechanical connection.

Abstract: The invention relates to an apparatus for unfolding a rolled-up, elongate hollow body, having: at least one elongate hollow body which has a closed cross-sectional profile, and an unfolding mechanism which has a winding core on which the elongate hollow body is rolled up and compressed in a first state and which, by rotation, transfers the elongate hollow body from the first state into an unrolled and unfolded second state, wherein the unfolding mechanism has a supporting device, wherein the supporting device has an inner supporting element which is arranged in a cavity within the elongate hollow body and at least partially lies against the inner wall of the elongate hollow body, and has an outer fixing element which is arranged outside the elongate hollow body in the region of the inner supporting element such that the elongate hollow body can be guided through between the outer fixing element and the inner supporting element, wherein the inner supporting element interacts with the outer fixing element in

Abstract: The invention relates to a method for producing a fiber-composite hollow component from a fiber-composite material which contains at least one fibrous material and one matrix material, wherein the fiber-composite hollow component is formed from at least two fiber-composite half-shells which in a joining edge region of the fiber-composite half-shells are joined to one another such that a cavity is configured between the joined-together fiber-composite half-shells, wherein the method comprises the following steps: providing a first fiber-composite half-shell formed from the fibrous material of the fiber-composite material, and at least one second fiber-composite half-shell formed from the fibrous material of the fiber-composite material; assembling the first fiber-composite half-shell and the at least second fiber-composite half-shell so as to form the fiber-composite hollow component; wherein at least one spacer element is inserted in the joining edge region between the first fiber-composite half-shell and
