PURPOSE: To obtain a fine spinning frame giving a strong real-twist yarn at a high speed by providing a guide member having a tip end opened close to the inlet part of a non-rotating yarn-guide tube, placing the guide member in a block for opening a drafted fiber bundle with a jet of gyrating air stream and placing a gyrating air stream blasting twist nozzle in a yarn guide tube path.

CONSTITUTION: A fiber bundle S is supplied through a sliver-feeding guide 14 and drafted with a drafting apparatus D consisting of a back roller 15, a middle roller pair 17 having an apron 18 and a front roller pair 19. The drafted bundle is introduced into a fine spinning frame A. The frame A contains a guide member 6 in a fiber- opening nozzle block 1 having a fiber-opening nozzle 4 blasting a gyrating air stream and has a twist nozzle 5 blasting a gyrating air stream in the path 7 of the yarn guide tube 2. The guide member 6 has its tip end opened near the inlet part 2a of the non-rotating yarn guide tube 2. The yarn is exposed to the gyrating air stream near the inlet part 2a of the yarn guide tube 2 to effect false-twisting and the separated fiber is wound around the fiber bundle S by the rotation of the yarn caused by the gyrating air stream blasted from the twisting nozzle 5 to obtain the objective real-twist yarn Y.
