Abstract: A method and equipment for tail threading in a paper machine in which tail threading is carried out in stages: the web (w) is guided to the broke treatment at a selected dryer (C1), a cut (11) is formed in the web (w) to separate a narrow tail (A) from the rest of the web, i.e. the broke web (B), prior to the said dryer (c1), the edge (Bnull) opposite to the cut of the broke web is turned away from the cutting point to form an open draw (C) between the tail (A) and the broke web (B), the tail (A) is guided from the selected dryer (c1) to the following section while the broke web (B) is transferred further to the broke treatment, while travelling in a controlled manner, the tail (A) is widened to the full width and the broke web (B) is simultaneously reduced away.
