Abstract (en)

[origin: US4240187A] An airstream impinging laterally on a thread can convey a running thread through an opening. This "placing" of threads in nozzles fails at elevated thread speeds. According to the invention, placing succeeds even at high thread speeds if a strong stream of propelling gas is divided in the nozzle into edge streams which are deflected outwards and a fine central stream which conveys the thread through the narrow opening.
