Abstract: An apparatus for automatically adhering tapes adheres a double-faced adhesive tape to a tip portion of a stock paper roll around which a stock paper is wound and adheres at least one fixing adhesive tape so as to bridge the tip portion and the stock paper roll. The apparatus includes a device for transporting the double-faced adhesive tape. The transporting device includes an endless belt transporting the double-faced adhesive tape while at the same time holding the double-faced adhesive tape on its transporting surface. The apparatus further includes a device for feeding the double-faced adhesive tape. The feeding device feeds the double-faced adhesive tape to the transporting surface of the endless belt while simultaneously stripping a strip paper adhered to one face of the double-faced adhesive tape. The apparatus further includes a device for feeding the fixing adhesive tape.
