1. A device for providing a tubular foil, comprising a frame with a position for an active product holder from which the tubular foil can be removed and at least one further position for at least one subsequent product holder with a subsequent tubular foil, comprising coupling means for attaching a leading end of the subsequent tubular foil to a tail end of a spent tubular foil, wherein the coupling means comprise a carriage onto which the tail end can be fixed, and wherein the carriage is controllable so as to bring the tail end of the spent tubular foil and the leading end of the subsequent tubular foil together, wherein the carriage comprises a drivable applicator device with opposite applicator members with mutually facing operative surfaces, wherein the applicator members can be manipulated between a spread position, wherein the operative surfaces lie removed from each other, and a clamping position wherein the operative surfaces lie clampingly on each other, wherein the applicator device comprises supply means for providing adhesive strips on the operative surfaces of the applicator members in the spread position, and wherein the applicator device can be controlled to bring the applicator members with the adhesive strips thereon into the clamping position, with interposing of the tail end of the spent tube and the leading end of the subsequent tube, in order to mutually connect the ends between the adhesive strips, and to bring the applicator members into the spread position in order to release the adhesive strips and the ends mutually connected thereby.
