Abstract (en)
[origin: WO2012156220A1] The invention relates to a method and an apparatus for producing intertwining knots in a multifilament thread. In this case, an air-stream pulse is directed through a nozzle opening transversely onto the thread. In order to produce a continuous succession of intertwining knots, the air-stream pulse is produced periodically with an interval between the air-stream pulses. In order to be able to produce an irregular thread structure, according to the invention the interval between successive air-stream pulses is continuously changed. To this end, the apparatus according to the invention has a nozzle ring carrying the nozzle opening, said nozzle ring being coupled to a drive. The drive of the nozzle ring is assigned a control device, by way of which a rotary speed of the nozzle ring is controllable for the purpose of changing an interval between the air-stream pulses.
