发明名称 FOERFARANDE OCH ANORDNING I TORKPARTIET I EN PAPPERSMASKIN VID STYRNING AV BANANS AENDFOERINGSBAND
摘要 In a method for guiding the leader of the web in the drying section of a paper machine, a narrow leader is cut out of the full-width web by water jets, or the equivalent, such as, for example, against a roller of the press section. The leader is guided by a plurality of air jets into a gap between threading ropes and is carried between the threading ropes over drying cylinders. The leader is detached from a rock roller of the press section by a first plurality of air jets and is guided by a second plurality of air jets into connection with a drying wire in the drying section of the paper machine. A third plurality of air jets are directed through the drying wire to the leader supported on the drying wire and detach the leader from the drying wire. Substantially immediately upon detachment of the leader from the drying wire, transverse air jets are directed at the leader and shift the leader into the gap between the threading ropes and move the leader between the threading ropes over the drying cylinders.
