Abstract (en)
[origin: WO2022258654A1] The invention relates to a device (42, 42', 42'', 42''', 52) for generating an atmospheric plasma jet (28) for treating a surface of a workpiece, comprising a plasma nozzle (3, 53, 53') designed to generate an atmospheric plasma jet (28), wherein: the plasma nozzle (3, 53, 53') comprises a nozzle assembly (44) having a nozzle opening (48, 48', 48'', 48''', 58, 58') for discharging a plasma jet (28) to be generated in the plasma nozzle (3); the nozzle assembly (44) can be rotated about an axis (A, B); and the nozzle opening (48, 48', 48'', 48''', 58, 58') has a cross-section with a shape deviating from a circular shape.
