PURPOSE:To provide the title production process so designed that a yarn is covered on the other yarn while twisting with the number of said twisting changed continuously, thereby making the yarn quality at the twisted part various with the wrapping yarn allowed to be projected in a looped manner at appropriate positions to an appropriate extent. CONSTITUTION:The first yarn 5 from the package 9 in a twister is delivered externally from the side of a yarn reserving disc 3 via the yarn guide hole 8 of said disc 3 succeeding a tenser 10 and a spindle shaft 1, and twisted twice before reaching a balloon guide 11. The second yarn 7 from a package 16 out of the twister is introduced, through a tenser 17 and the lower part of the spindle shaft 1, into the yarn guide hole 6, being guided from the side of said disc 3 to the balloon guide 11, where the yarns 5 and 7 are mutually twisted; and the amount of the yarn 7 to be fed from a feed roller 18 is changed with the rotational speed of said feed roller 18 kept higher than that of the winding roller 14. |
