PURPOSE:To carry out easily the yarn ending of bound spun yarns, by using a cut path wall having an air suction hole provided on the downstream side of a fluid jetting twisting apparatus. CONSTITUTION:A fluid jetting twisting apparatus 5 provided between feed rollers 3' and 4 and taking off rollers 7 and 7' has a cut path wall having an air suction hole 22. Thus, a cut 14 is provided on the extension of the apparatus wall of the fluid jetting twisting apparatus 5 having fluid jetting nozzles 17 and 24, and the air suction hole 22 perpendicular to yarn paths 11 and 13 is provided on the remaining part of the apparatus wall. If the yarn breakage occurs in the bind spinning in the fluid jetting twisting apparatus 5, air is sucked through the air suction hole 22 while feeding a yarn end in the reverse direction from the taking off rollers 7 and 7' to join the yarn end to a yarn end fed from the fluid jetting twisting apparatus 5 at the position of the air suction hole 22. Thus, the yarn ending is carried out by the resulting turning stream in the fluid jetting twisting apparatus 5. |
