Then the yarn Y slide contacts the tapered portion 6c of the upper spindle 6 and then forms a balloon 22 at the outside of the supply package 14a. Thereafter, the yarn Y is guided to the tenser 17 disposed at the upper portion of the prohibiting member 10, and then it is guided from the tenser 17 to the outside of the prohibiting member 10.
  • the yarn Y is subjected to a predetermined tension during the above-described operation and forms a balloon 23 at the outside of the prohibiting member 10.

Since the lower spindle 2 rotates in a direction opposite to that of the upper spindle 6, the yarn Y is imparted with real twists of N1 (turns) in a direction the same as that of the twists imparted by the upper spindle 6 between the tenser 17 and the yarn introducing hole 25. Further, while the yarn Y passes through the yarn introducing hole 25, the yarn Y is imparted with twists, the direction of which is the same as that of the previously imparted real twists and the number of which is N1 (turns).
  • the yarn is subjected to real twists, the number of which is double of the sum of the rotational numbers of the upper spindle 6 and that of the lower spindle 2.

  • shaft portion is formed in the upper spindle
  • the formation of the cylindrical portion and the shaft portion may be reversed.
  • a yarn twisting spindle device when the yarn Y moves towards the center of rotating axis and forms so called reverse balloon 23, the yarn tends to wraps around the tapered portion 2c of the lower spindle 2 as the twisting spindle rotates.
  • the tension in yarn at the balloon is regulated by adjusting the wrapping angle ⁇ (see Fig. 8) so as to adjust friction between the yarn Y and the tapered portion 2c of the lower spindle 2.
  • the wrapping angle ⁇ is excessively large, the tension adjusting function of the lower spindle 2 may be lost. As a result, breakage of filaments constituting the yarn Y of yarn breakage may occur.

  • the length of the arced slit 2f is set at a predetermined amount. The yarn left the tenser 17 enters into the slit 2f after it forms a balloon 23 and then it contacts the surface of the tapered portion 2c of the lower spindle 2.
  • the wrapping angle ⁇ of the yarn Y is within an allowable range, and accordingly, the tension in yarn at the balloon 23 is regulated by the friction contact between the yarn Y and the tapered portion 2c. Contrary to this, if the yarn wraps around the tapered portion 2c beyond the allowable wrapping angle, the tension in yarn may become excessively large.
  • the wrapping angle ⁇ of the yarn Y is limited by the slit 2f, and the tension adjusting function can be always maintained within an adequate level.

  • the yarn twisting spindle device of the present invention obviate a problem that it requires an extra bearing member, which is essential for a conventional yarn twisting spindle device, for power transmitting member.
  • the size of the yarn twisting spindle device can be easily reduced, and the tension in the outer balloon becomes excessively small compared with that for a conventional yarn twisting spindle device. Consequently, the operating speed of the yarn twisting spindle device according to the present invention can be enhanced, and the twisting speed also can be enhanced while the size of the supply package can be enlarged.
  • the yarn twisting spindle device of the present invention has sufficient resistance to vibration and is high safety in a high speed range operation.
