An apparatus for transferring formwork rings (1) of inner formwork (2) for cast-in-situ tunnel lining (3) has on the one hand a tubular supporting bridge (4) running essentially centrally inside the inner formwork (2) and on the other hand a transport truck (5) for the formwork rings (1) to be transferred, which transport truck (5) is guided on the supporting bridge (4) and is also movable along the latter. With its front end, the supporting bridge (4) is mounted in a tunnel-driving machine in such a way that it can move relative to the tunnel-driving machine. In such an apparatus, the supporting bridge (4) can be moved forward irrespective of the working state of the tunnel-driving machine and in addition can be used for absorbing linear reactions when bracing elements, in particular rods (7) stressed in tension, passing through the intermediate space (6) formed by the tunnel wall and supporting bridge (4) are provided in the rear end area of the supporting bridge (4), which rods (7) can be secured with one of their ends to the tunnel wall, preferably by a linked expanding ring (11), and are connected with their other end to the free end of hydraulic cylinder/piston arrangements (9) fastened to the supporting bridge (4) and acting in the direction of the supporting bridge (4). <IMAGE>
