Abstract
An apparatus for a dryer section of a paper or board machine has a drying group (R) and an impingement drying unit () which is placed above and/or below a row (DSR) of drying cylinders (). A drying fabric () supported paper or board web () is conducted past the impingement drying unit () having at least one impingement surface (IP, IP) the side profile of which is straight, changeably curved in its radius of curvature, in the shape of a broken line or a selectable combination of these, and that the impingement surface or a tangent line to the impingement surface or a line passing via the beginning and the end of the impingement surface or an extension of the line forms on the impingement side an angle with a horizontal plane parallel to the machine level, which angle is ≦120°, advantageously 120°–60°, most advantageously about 90°.
