<p>The device has an air outlet nozzle, whose nozzle body has two distanced nozzle segments (11,12), which form a nozzle slot (10). The contour of the nozzle segments is bent at inner surfaces facing each other and the segments form a nozzle slot sectionally converged in flow direction of the air. An airfoil-shaped core beam profile (13) arranged between both the nozzle segments is provided. The core beam profile is divided into two partial beams.</p> |
