Abstract: A reel threader for treading the tail of a paper making web around a partial reel. A flexible panel with interior passages forming an air distribution network has openings on one surface to provide a plurality of air streams out of the surface. The panel is positioned by a computer controlled movable support frame in an arc which is spaced from and concentric with the lower and side portion of a partial reel, regardless of its diameter, to form a gap. The tail passes from the nip into the gap and is pulled through the gap by the rotating periphery of the partial reel.
