<p>The device has a rotatable rotor (13) that is provided with nozzle heads (14) directed radially outward. The nozzle heads are provided with a gas feed line and a nozzle (16). The nozzles are arranged in a common plane which is arranged approximately perpendicular to supporting surfaces (12) of feed rails (7,8) and runs through central axis (17) of a hollow object. The rotor is rotated in conveying direction (12) during conveying of the hollow object. The nozzle head interacts with the head area (4) of respective hollow object in an area between rotor and feed rails.</p> |
