摘要： The invention relates to a method and device for stabilizing a paper web in a group of cylinders in the dryer section of a paper machine. The group of cylinders are arranged in a row of drying cylinders and a corresponding row of leading rolls or equivalent placed as interlocked with the drying cylinders. The group of cylinders is provided with a single-wire draw so that the heated drying cylinders in the group are placed outside the loop of the drying wire and the leading rolls in the group are placed inside the loop of the drying wire. The stabilization device is arranged in the area between adjacent drying cylinders and the leading roll or equivalent placed as interlocked between the adjacent drying cylinders in the group of cylinders. Air is blow from the device and directed in the direction opposite to the running direction of the paper web. A nozzle opening of the stabilization device is shaped so that the air flow follows a substantially smooth face of the stabilization device while, at the same time, ejecting surrounding air along with it. In preferred embodiments, the smooth face is substantially parallel to the drying wire and the group of cylinders is formed as a compact geometry.
