PURPOSE:Pressurized air is fed through the air hole which has been bored along the shaft center of the spindle to the jetting nozzle inside the balloon or to the other jetting nozzle rotating around the spindle center. CONSTITUTION:In order to allow the bobbin supporter 16 to rotate, pressurized air is introduced from the air chamber 34 through the air chamber 37 and a pair of holes 36 into the chamber 18 and jetted from the nozzle 8a toward the turbin blades 16a. Further, pressurized air is sent from the air chamber 34, through the air hole 42 and the chamber 43 to the nozzle 45 near the yarn turning point. The air nozzle 50 receives pressurized air from the air chamber 34 through hole 42, chamber 43, hole 47 chamber 46, path 30 and chamber 48. These holes and chambers can be formed very easily. |
