ABSTRACT:
The air jet of the present invention is of the "bullet nose" type and is provided with a conical outer surface (32) on the exit end for directing the ambient air surrounding the exit end of the jet downwardly and inwardly to join the yarn and pressurized air leaving the exit orifice (22) of the jet. An "airfoil" type baffle (40) is spaced from the exit orifice (22) and includes an arcuate leading surface (41) positioned to be engaged by the yarn and pressurized air after leaving the exit orifice (22) and a substantially wedge-shaped portion extending away from the arcuate leading surface (41) and being defined by the converging upper and lower planar surfaces (43, 44). The baffle (40) is supported for adjustment to vary the downstream distance and the perpendicular position relative to the exit orifice (22).
