摘要

The yarn handling device has a nozzle body (1) with yarn channels and blowing hole (3). The yarn channel is formed from a wider yarn channel area (2a) and a narrower yarn channel area (2b). The transition from the wider yarn channel area into narrower yarn channel area takes place in the transition region. The blowing hole is present in the transition region. The impact planes of the yarn channel areas are collinear. The height of the wider yarn channel area is larger than the height of the narrower yarn channel area.
