Abstract
Device for drying a web in a two-screen dryer section. The device may include a plurality of heatable dryer cylinders arranged in vertically spaced upper and lower cylinder rows, an upper endless screen associated with the upper cylinder row and a bottom endless screen associated with the bottom cylinder row, and a screen guide roll associated with one of the upper and lower endless screens. A shaft may be formed between adjacent cylinders in a cylinder row and bounded by one of the upper and lower endless screens guided around the adjacent cylinders and the screen guide roll. An air box and a blowing device may be positioned within the shaft, and the blowing device may be arranged in a region of separation between the screen and the screen guide roll to direct an air flow through the screen. The device may also include a longitudinal sealing strip coupled to a surface of the screen guide roll in a vicinity of the region of separation.
