Abstract
The system for monitoring the movement of a cutter arm and of the cutting tools rotatably mounted on said cutter arm in a tunnel-driving machine comprises a receiver (13), which has a sighting device (14) that is mounted to be displaceable and pivotally movable transversely to the longitudional axis of the tunnel-driving machine. The movement of the receiver (13) to a position in alignment with a guide beam (3) is transmitted to a simulator, which contains a model (62) of the desired profile and in which a three-dimensional scale model (54) of the cutting tool is mounted to be pivotally movable and displaceable analogously to the receiver (13) (FIGS. 4 to 11).
