A method of manufacturing a ribbon roll by joining a splice tape to a ribbon, is capable of accomplishing automatization to deal with splice tapes different in length and kind. This method comprises a ribbon supply process, an edit process for joining first and second splice tapes to the ribbon and a take-up process for rolling up the ribbon joined to the first and second splice tapes. In the edit process, the first and second splice tapes are joined by an adhesive tape sticking section and its feeding quantity is adjusted by an accumulator. On the other hand, the ribbon is drawn out by a given length from a supply unit and cut. A rotating bed 42 supporting the cut ribbon is rotated so that the end of the cut ribbon comes into an opposed relation to the end of the first or second splice tape. In this state, the ribbon and the splice tape are joined to each other.
