A threading device and a method for threading a tail of a web, wherein, for guiding the path of a tail separated from a full-width web in a paper machine or a paper finishing device, the threading device comprises a suction channel, placed at least partly in a paper machine portion and provided with a reduced pressure for gripping the tail, and transfer means for transferring the suction channel in the portion of the paper machine and simultaneously for releasing the tail to the portion. In the method for threading of the tail, before threading the full-width web through a portion in a paper machine, the tail is separated from the web, the tail is cut, and the tail is conveyed in the portion of the paper machine, after which the full-width web following the tail in a continuous manner is conveyed to the portion, by providing a reduced pressure in a suction channel, by transferring an inlet opening of the suction channel close to the tail separated from the web, by transferring the tail into the suction channel by means of the reduced pressure prevailing therein, and by releasing the tail to the portion of the paper machine by transferring the suction channel and particularly the inlet opening in the direction of the portion of the paper machine.
