<p>The invention relates to a device for the automatic selection of rolls of tape, particularly adhesive tapes, which are used in dispensers. The inventive device ensures that a dispenser uses certain types of tape rolls selectively by preventing unsuitable rolls from being placed correctly therein or from rotating. According to the invention, lugs (62) which surround the mandrel (63) of the dispenser only allow a tape core having a corresponding annular groove on one of the sides thereof to be positioned correctly in the dispenser and to rotate.</p> |
