Zusammenfassung:	An annular nozzle contains a nozzle body, the nozzle body comprising at least one annular gap for the discharge of a film. The annular gap is laterally bounded by a stationary wall and a flexible lip. A plurality of threaded pins and a corresponding number of bolts are arranged in the nozzle body. Each of the threaded pins is rotatably mounted in a first bore in the nozzle body. Each of the bolts is slidably mounted in the nozzle body in a second bore in the nozzle body. The bolt is in contact with the flexible lip and the corresponding threaded pin so that a compressive force can be transferred from the threaded pin to the bolt and via the bolt to the flexible lip.
