    摘要: The inventive device for intermingling multifilament yarns has a yarn channel in which the filaments of the multifilament yarn can be intermingled by means of a flow of medium emerging from an opening cross-section of a blast nozzle arrangement, especially flows of pressurised air. The opening cross-section of the blast nozzle arrangement is essentially symmetrical to the longitudinal axis of the yarn channel. A particular blast nozzle arrangement (35) divides the flow of medium into a main flow and pairs of secondary flows. The main flow flows into the middle area (29) of the yarn channel (13), one of the secondary flows flows into one edge area (33) and the other secondary flow flows into the other edge area (33) of the yarn channel (13). The main (H) and secondary (N) flows are essentially oriented in the same direction.
