<p>To provide a threading apparatus that can thread yarn by feeding compressed air when the yarn is fed from a large diameter portion of a spindle member to a small diameter portion of the spindle member preceding the large diameter one. A spindle member is divided and a pipe consisting of a filter member is installed in the middle of the spindle, so that when compressed air is injected from the rear end of the spindle having a large diameter toward its tip having a small diameter and preceding the rear end, a suction flow that sucks external air at the rear end is generated while excessive air is discharged to the exterior through the filter member, thereby maintaining a yarn feeding air flow in the center of the spindle member. Thus, the present invention can provide a threading apparatus that can feed compressed air to thread yarn from the rear end having a large diameter toward the preceding small diameter portion. <IMAGE></p> |
