dc.description.abstractIn this paper, a new air-jet weft-insertion system, which does not require any air-guide, such as a confusor or profiled reed, is discussed. Characteristics of the new double-holed relay nozzles, studied by using Pitote-tube measurement and Schlieren photography, are presented. The results of air-velocity and turbulence profiles measured by using a Laser Doppler Anemometer (LDA) are reported. The tensions developed in a stationary yarn are also studied. Schlieren photography and Pitote-tube measurements show that, in many nozzles, the jets are either divergent or parallel with an angular lift. Measurements indicate that the air velocity near the jet axis in the weft-insertion direction is much less, with the vertical component of the air velocity accounting for more than one-third of it, and that the main nozzle imparts a higher tension to stationary yarn than the relay nozzles.en
