Claim Text:
1. Device for producing intertwining knots in a multifilament thread, the device comprising: a rotating nozzle ring, which has on a circumference of the nozzle ring a circumferential guide groove and at least one nozzle channel which opens radially into the guide groove, a stator which has a pressure chamber with a chamber opening, wherein the pressure chamber can be connected via a compressed air connection to a compressed air source and wherein by rotation of the nozzle ring the nozzle channel can be connected to the pressure chamber via the chamber opening in order to produce an air stream pulse, and a cover which is associated with a portion of the guide groove and forms a treatment channel in the guide groove together with the nozzle ring opposite the chamber opening of the stator, wherein at least one of the nozzle ring and the cover has at least one auxiliary nozzle channel opening into the treatment channel, wherein the auxiliary nozzle channel is connected constantly to the compressed air source, wherein the auxiliary nozzle channel has a free flow cross-section which is smaller than a flow cross-section of the nozzle channel, and wherein the auxiliary nozzle channel and the nozzle channel open, offset with respect to one another, into the treatment channel in such a way that different blowing directions can be produced.
