Abstract: The invention concerns a machine and a method for automatically restoring cinematographic films comprising connections produced by adhesive tapes, by unwinding the film in front of means (28) detecting the connections, stopping the unwinding, holding the film on either side of the detected connection with clips (30), cutting the film in the middle of the connection, eliminating the bits of adhesive tape, cleaning the film and fixing a new connection, then proceeding with the unwinding, eliminating with means (34) the overlapping lateral portions of the new connection and visually controlling the new connections with means (36). The invention enables to automatically restore films comprising connections consisting of adhesive tape.
