The invention relates to a device for unfolding a rolled-up elongate hollow member having:at least one elongate hollow member which has two elongate shell member halves, andan unfolding mechanism which has a fixed base structure and a winding core which is rotatably supported on the base structure and on which the at least one elongate hollow member in a first state is rolled up and compressed and which by rotating moves and unfolds the elongate hollow member from the first state into an unrolled and unfolded second state so that an elongate hollow space is formed between the two shell member halves of the at least one elongate hollow member,wherein the at least one elongate hollow member has as a first end a hollow member root, via which the elongate hollow member is secured to the rotatably supported winding core,whereinthe first shell member half of the at least one elongate hollow member is secured in the region of the hollow member root to the rotatably supported winding core, andthe unfolding mechanism has an expansion mechanism which in the region of the hollow member root is in engagement with the second shell member half and which moves the second shell member half in the region of the hollow member root away from the rotatably supported winding core in order to expand the cross-section of the at least one elongate hollow member in the region of the hollow member root when the elongate hollow member is unrolled from the rotatably supported winding core.
