ABSTRACT:
A dryer section in which a paper web to be dried meanders successively over several drying cylinders, which are arranged in two rows one above the other. To the top row of cylinders is allotted a top supporting belt and to the bottom row of cylinders a bottom supporting belt. Between each two drying cylinders each of the supporting belts runs over a carrier roll. At the open paper draws are provided web stabilizers of which each exhibits several nozzle elements with one air blow slot each and a web-guiding surface interacting with it. The direction of flow of the blow air is at all nozzle elements the same as the direction of travel of the paper web. Each web stabilizer is designed as an exhaust-air box surrounding the nozzle elements, to which an exhaust-air pipe is connected.
