<p>The nozzle (1) has an adjustable air jet recess with a spin production area (2). A convergent-divergent separating area (3) with a tearing edge (4) is arranged successive to the production area. The edge is rotatably arranged in a plane that is perpendicular to a center longitudinal axis of the nozzle. The edge is spaced apart from an outer cross section of the nozzle, and has a right angle with a longitudinal section. A hollow cylindrical region with a minimum inner diameter (D1) is arranged before the edge. The inner diameter is smaller than an inner diameter (D2) of the cross section.</p> |
