Abstract: TA multifunctional nozzle for a spinning machine used to produce at least 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.

Abstract: The invention relates to a device (1) for individualizing fibers of a supplied fiber sliver end and to a spinning device (2) comprising such a device (1). The device (1) comprises a first hollow body section, to which pressure can be applied and which comprises an inlet channel segment (3) for receiving and guiding a supplied fiber sliver end together with a fluid in the direction of an unraveling channel segment (6) arranged downstream thereof, and the unraveling channel segment (6), which communicates with the inlet channel segment (3) and is arranged downstream thereof, for unraveling the fiber sliver end supplied together with the fluid into individual fibers. The unraveling channel segment (6) forms an annular channel (10) which communicates with the inlet channel segment (3).
