PURPOSE:To carry out the yarn ending of bound spun yarns with ease and form yarn ended parts without the deterioration in strength, by means of fluid jetting nozzles for turning the fluid in the direction opposite to the direction of a turning stream in a fluid jetting twisting apparatus on the downstream side of the fluid jetting twisting apparatus with a path having a cut wall with an air suction hole placed therebetween. CONSTITUTION:A cut path wall having a cut with an air suction hole 22 is provided on the side of taking off rollers 7 and 7' of a fluid jetting twisting apparatus 5 provided between feed rollers 3' and 4 and the taking off rollers 7 and 7', and fluid jetting nozzles 20 are provided on the downstream side of the path wall. The nozzles 20 are mounted to turn a jetting fluid in the direction opposite to the turning direction of jetted streams in the fluid jetting twisting apparatus 5 with respect to the path 15 coaxial with yarn paths 11 and 13. If the yarn breakage occurs in the bind spinning in the fluid jetting twisting apparatus 5, the fluid is jetted from the nozzles 20 to form a turning stream in the opposite direction in the path 15. A yarn end is fed from the downstream side in the opposite direction while sucking air from the air suction nozzle 22, mutually entangled and ended with a yarn end fed from the twisting side by the air stream caused by the air suction hole 22. |
