It is projected and supported, and each bobbin holder 11 and 12 is equipped with a plurality of bobbins B (six in the figure), and one bobbin holder 11 is a winding position P ₁ and the other bobbin. The holder 12 is located in the standby position P ₂ .

The thread Y is wound around the bobbin B of the bobbin holder 11 located at the winding position P ₁ , and the turret plate 2 is rotated 180 ° each time the bobbin B becomes the full bobbin FB. to, the take-up position (P ₁₎ in only the bobbin (FB) to the take-up position (P ₁₎ in the standby position (P _2), the stand-by position the publication blank (EB) prepared at the standby position (P ₂₎ (P ₂ ) in the take-up is moved to a position (P _1), it is converted to the yarn (Y) by a public performance vents only bobbins (FB) bobbin (EB) in the ball taking a continuous volume.
