An apparatus to facilitate tail threading of a paper web and a method of threading the tail of a paper web (1) to be coated through a coating line during startup or web break, in which an edge strip is slit from the web to act as the tail of the web which is first threaded through the line and then widened to the normal width of the web by moving the edge strip slitter. Said edge strip is first guided to a movable support element (12) located after the edge strip slitting point in the travel direction of the web (1) and the strip is supported against said movable support element (12) and is passed supported by said movable support element (12) to the next support element (14). A guiding/auxiliary support element (31) is brought to the discontinuity points of web support path and the edge strip is passed with the help of said auxiliary support element over the discontinuity and the edge strip is passed through the entire coating line supported by said sequential support elements (2, 12, 14, 18, 19, 22, 25) and said guiding/auxiliary support elements (31).
