PURPOSE:A mechanism for receiving and delivering yarns, having a yarn suction tube, a yarn end holding tube and a threading member near a position for moving a false twisting nozzle to the side of a pneumatic false twisting bundled spinning apparatus, and capable of facilitating the yarn ending operation. CONSTITUTION:A mechanism for receiving and delivering yarns having a yarn end suction tube 21 for coming into contact with the inlet part of a pneumatic false twisting nozzle 4 moved to the side on the occurrence of yarn breakage, and introducing a yarn end from the outlet part of the pneumatic false twisting nozzle 4 while sucking air therethrough, threading the yarn end in the reverse direction through the pneumatic false twisting nozzle 4, and retreating thereafter, a yarn threading member 29 for hooking a yarn (Y) connecting from the pneumatic false twisting nozzle 4 to the yarn end suction tube 21 on a hook (29a) thereof, carrying the yarn (Y) to an opening of a yarn end holding tube 28 provided just near the yarn (Y) and the yarn end holding tube 28 for holding the yarn end. The yarn end suction tube 21 and yarn threading member 29 are then shunted, and the pneumatic false twisting nozzle 4 and the yarn end holding tube 28 are returned to the normal positions to join the yarn end to the fiber bundle in the drafting mechanism. Thus, yarn ending is carried out. |
