摘要:
In order to conduct thoroughly pre-mixed hot gas into a ring spinning nozzle by a rotational flow in such a manner that sufficient quantities of hot gas are available for drying the filaments situated on the inside without causing backflow and without any significant movement of the filaments by turbulence, an annular chamber with tangential inlet is placed around the ring spinning nozzle. The internal wall of the chamber is separated from a circular chamber by equalizers in its upper region while on its underside it is separated from the spinning chamber by equalizers and metal gauzes at the level of the lower edge of the spinning nozzle. The circular chamber is also separated on its underside from the spinning chamber by equalizers and metal gauzes.
