Abstract (en)

[origin: WO2009141508A1] The invention relates to a method in tail threading in the dryer section of a fiber web machine including successive dryer groups (38). The dryer group (38) includes dryer cylinders (22), turning rolls (24), vacuum boxes (62), one dryer fabric (26) traveling as single fabric run (20) via the dryer cylinders (22) and the turning rolls (24), and in tail threading of the web (34) the end (42) of the web (34) is led at full width through the dryer section (14). In addition, on the side of an opening gap (32) formed by a dryer cylinder (22) and the dryer fabric (26), the full width web (34) is blown off from the dryer cylinder (22), at least at the edges (33, 35) of the web (34). The invention also relates to a corresponding arrangement (28).
