Abstract
Techniques produce intertwining knots in a multifilament thread. In such techniques, an air stream pulse is generated by a nozzle channel opening into a treatment channel periodically with an interval between successive air stream pulses. During an interval, the air stream pulse is directed transversely onto the thread guided in the treatment channel so that a continuous sequence of intertwining knots is produced in the running thread. An auxiliary air stream is generated continuously or discontinuously and the auxiliary air stream and the air stream pulse are blown in together into the treatment channel.
