to 4 is a quadruple nozzle weft insertion device having a weft guide 2a with a bullet like or conoid shape the weft guide 2 is a streamlined object that is an object whose curvature does not disrupt the smooth flow of fluid thereacross and causes a high velocity air stream to adhere thereto without causing turbulence the diameter of the guide 2 increases until a mid point of the streamlined portion and decreases thereafter until it terminates with a pointed end the weft guide 2a is mounted in the center between the four nozzles 1 1 39 1 34 and 1 39 34 and positioned in a coaxial relationship with the weft path line of sight 1 1 the guide 2a is positioned to contact the pressurized air discharged from the nozzles the high velocity air streaming from each nozzle carries a weft the air stream tends to adhere to the guide 2 in accordance with the coanda effect since the air stream is carrying the weft in the direction of the pointed end which is on the line of sight of the desired weft path as a result the wefts are directed toward the center of the reed channel by floating in the air stream redirected by the guide 2 a second embodiment of the present invention illustrated in fig5 to.
