A multifunctional nozzle for a spinning machine used to produce real-twist yarn. The multifunctional nozzle comprises a nozzle channel open on one side in a nozzle housing and in which a vortex flow can be generated. A nozzle body which is shorter than the nozzle channel is provided with a through-channel for the passage of a thread or fibre band. An annular gap with a narrow point is formed within the nozzle channel. The annular gap tapering on both sides at the narrow point. The narrow point is arranged downstream of a fluid inlet which leads to the nozzle channel. A hollow body-type flow conducting body is provided between the annular gap and the open end of the nozzle channel for guiding the thread or fibre band together with a fluid, the annular gap being formed between the nozzle body and the nozzle housing and/or the flow conducting body.
