  • the second yarn Y2 is not slacked at the tension applying device (the gate tensor 49). That is, tension is applied appropriately to the second yarn Y2 in the tension applying device (the gate tensor 49).
  • the second yarn Y2 is fed without being slacked.
  • the tension applying device (the gate tensor 49) and the initial tension applying device (the ball tensor 48) are provided at the bent part of the yarn path of the second yarn Y2.
  • the tension applied to the second yarn Y2 becomes even.
  • the tension applying device is not provided at the bent part, the fluctuation in the tension applied by the guide members or the like at the bent part becomes large.
  • the second yarn Y2 is fed from the initial tension applying device (the ball tensor 48) towards the tension applying device (the gate tensor 49) without being bent.
  • the fluctuation in the tension of the second yarn Y2 is suppressed.
  • an angle at which the second yarn Y2 is introduced into the tension applying device (the gate tensor 49) can be set appropriately, and the efficiency in which the tension is applied by the tension applying device (the gate tensor 49) is improved.
  • the initial tension applying device is a ball-method tensor (the ball tensor 48).
  • the second yarn Y2 passes through the tensor (the ball tensor 48), the second yarn Y2 is not rasped against the tensor ball 54 or the receiving member (the yarn guide 53) of the tensor ball 54.
  • the initial tension in other words, in case of applying tension to the slacked yarn, it is effective to apply resistance to the yarn by sandwiching the yarn.
  • the method for sandwiching the yarn is a disk method and not the ball method, there are defects that the yarn is rasped against the disk.
