摘要
To facilitate the introduction of running yarns into injector nozzles the cross section of the inlet openings of the said nozzles are enlarged before the yarns are laid in, the yarns are sucked into the enlarged openings and subsequently the openings are reduced to their initial dimensions. The injector nozzles are preferably used in jet stufferbox texturizing processes or with suction guns. Without special threading aids, yarns and threads supplied at high speed are sucked in automatically and conveyed into spaces under elevated pressure.
