1. A device for manufacturing a fiber-reinforced fuselage shell for an aircraft, wherein the fuselage shell comprises a plurality of stringers spaced apart from each other, the device comprising: a base frame for forming a load-bearing, rigid, substructure with an outwardly-curved mounting surface for the positive-rigging of a fiber-reinforced fuselage shell to be manufactured;a plurality of actuators affixed to and extending radially outwards from the outwardly-curved mounting surface and being longitudinally adjustable;a plurality of mold channels attached at the distal ends of the plurality of actuators and configured for receiving the plurality of stringers;wherein the plurality of mold channels are interconnected by at least one of a plurality of elastic belts and additional mold channels for forming a vacuum-tight closed mold surface, wherein the plurality of elastic belts are arranged along longitudinal edges of the mold channels; andwherein the plurality of actuators are hingeably mounted, by associated joints, on the outwardly-curved mounting surface. 2. A device for manufacturing a fiber-reinforced fuselage shell for an aircraft, wherein the fuselage shell comprises a plurality of stringers spaced apart from each other, the device comprising: a base frame for forming a load-bearing, rigid, substructure with an outwardly-curved mounting surface for the positive-rigging of a fiber-reinforced fuselage shell to be manufactured,a plurality of actuators affixed to and extending radially outwards from the outwardly-curved mounting surface and being longitudinally adjustable;a plurality of mold channels attached at the distal ends of actuators and configured for receiving the plurality of stringers;wherein the plurality of mold channels are rigidly interconnected by at least one of a plurality of hinges and additional mold channels for forming a vacuum-tight closed mold surface, wherein the plurality of hinges are arranged along longitudinal edges of the mold channels; andan actuator for folding down a side flank of the closed mold surface, wherein the side flank is configured to be hinged over the closed mold surface;wherein the actuator is hingeably mounted, by associated joints, on the outwardly-curved mounting surface. 3. The device of claim 2, wherein the plurality of rigidly interconnected mold channels is adjustable by way of the actuator shared among the plurality of interconnected mold channels. 4. The device of claim 1, wherein each of the plurality of mold channels comprises a groove for guiding vacuum and vacuum connections for the closed mold surface. 5. The device of claim 1, wherein each of the plurality of mold channels comprises a groove region, wherein the groove region comprises a plurality of positioning sections arranged so as to be spaced apart from each other and reducing the diameter of a groove cross section of the groove region, and corresponding to the desired geometry of one of the plurality of stringer to be inserted. 6. The device of claim 1, wherein the base frame is configured to be moved on a transfer carriage with a lifting mechanism or a lifting-rotating device for moving together a laminating-bonding device and the device for manufacturing the fuselage shell, and for positioning the laminating-bonding device and the device for manufacturing the fuselage shell relative to each other.
