Abstract (en)
Method and device in a multi-cylinder dryer of a paper machine in the threading of the paper web, said threading taking place substantially without a system of threading ropes.

The leader (S) is guided by means of air blowings (F1) extending across a substantial proportion or the whole of its width (L1), said air blowings (F1) being applied from the doctor beam (12) to the area (K) of the by of its doctor blade (14) at a certain small angle (B) in relation to the plane of the doctor blade (14). <IMAGE>
