Abstract

Pneumatic nozzle for spinning yarns from synthetic and natural fibres is composed of two concentric tubes defining an annular space between them, the ends of the tubes overlapping partially and supporting helical vanes whose pitch and size depends on the difference of the dia. of the two tubes.
