TailDoc threads a sheet tail through the machine with the help of compressed air. The tail-threading unit consists of a doctor blade and a blade holder. The doctor blade separates the sheet tail from the cylinder surface with the help of a counter-directed air blow, and guide blows usher the tail to the next fabric nip. Nozzles placed in the blade holder area create a tail-stabilizer zone that settles the tail, prevents cross-machine sway and ensures fast tail tensioning and smooth transfer. The tail-threading unit is suitable for double-fabric dryer sections of paper or board machines.
