  • the ground wire 70 of the present embodiment has a spring property (elasticity). Because the ground wire 70 has a spring property, the ground wire 70 is shortened and the entirety of the wire is attached to the frame 92 when the yarn threading is not performed, with the result that a space for attaching the ground wire 70 is downsized. The ground wire 70 is therefore attached to a location where the wire does not interfere with the yarns 10 passing in front of the frame 92.

When yarn threading is not performed, the yarn threading assisting tool 160 may be stored in the vicinity of the spun yarn take-up machine 1. When performing the yarn threading, the operator draws the ground wire 170 out from the casing 175a of the winding mechanism 175 of the yarn threading assisting tool 160 and magnetically fixes the magnet 171 to the frame 92. As a result, electricity becomes transmittable between the ground wire 170 and the frame 92.
  • the ground wire 170 conductively attached to the main body 165 can be conductively attached to the conductive frame 92 of the spun yarn take-up machine 1. It is therefore possible to discharge the static electricity accumulated in the main body 165 of the yarn threading assisting tool 160 to the frame 92 via the ground wire 170, when the operator performs the yarn threading to the fulcrum guides 13 by using the yarn threading assisting tool 160. As a result, it is possible to prevent the operator from receiving an electric shock when performing the yarn threading.
  • the ground wire 70 may be attached to the frame 92 by another means.
  • the ground wire 70 may be fixed by using a screw.
  • the hook member 72 may be attached to the frame 92 by using another means.
  • a ring-shaped member may be provided on the frame 92 to hook the hook member 72.
  • hook members 271 and 272 are fixed to end portions of a ground wire 270, respectively.
  • the hook member 271 is hooked into a ring-shaped member 274a of the frame 92.
  • the hook member 272 is hooked into a ring-shaped member 275a of the frame 92 when the yarn threading is not performed.
  • the entirety of the ground wire 270 is attached to the frame 92 when the yarn threading is not performed.
  • the hook member 272 is detached from the ring-shaped member 275a and is hooked into the hole 63 of the yarn threading assisting tool 60 in the same manner as in the first embodiment (see FIG. 5 ).
  • the ring-shaped members 274a and 275a and the hook members 271 and 272 are made of a conductive material. On this account, as the hook member 271 is hooked into the ring-shaped member 274a, the ground wire 270 is conductively attached to the frame 92.
  • the hook member 272 may be magnetically attached to the frame 92 in the same manner as in the first embodiment.
  • the ground wire 70 (170, 270) is attached to the frame 92 which is above the take-up unit 4 and the yarn threading portions (fulcrum guides 13 and yarn guides 20 to 24) to which yarns are threaded by the yarn threading assisting tool 60 (160)
  • the position where the ground wire 70 (170, 270) is attached is not limited to this.
  • the ground wire 70 (170, 270) may be attached to a frame different from the frame 92 lower than the yarn threading portions and the take-up unit 4.
  • the fulcrum guides 13 are aligned in a line in the front-rear direction
  • the arrangement direction of the fulcrum guides 13 is not limited to this.
  • the fulcrum guides may be aligned in a line in a direction intersecting with the front-rear direction, or may not be aligned in a line.
  • the ground wire 70 is detachably attached to the yarn threading assisting tool 60 by the hook member 72 (272), the disclosure is not limited to this arrangement.
  • the ground wire 70 is detachably attached to the yarn threading assisting tool 60 by an openable ring-shaped member 372 instead of the hook member 72 (272) .
  • the ring-shaped member 372 is formed of two circular-arc-shaped members 372a and 372b. The circular-arc-shaped members 372a and 372b are connected to each other at end portions by a shaft 372c.
  • the ring-shaped member 372 is switched between a closed state in which a ring shape is formed as shown in FIG. 9(a) and an open state in which the ring is partially cut out as shown in FIG. 9(b) , as the circular-arc-shaped members 372a and 372b are rotated about the shaft 372c.
  • the ring-shaped member 372 is opened.
  • the ring-shaped member 372 is closed. This prevents the ground wire 70 from being detached from the yarn threading assisting tool 60 during the yarn threading.
  • the ring-shaped member 372 may not be formed of the two circular-arc-shaped members 372a and 372b.
  • the ring-shaped member may be formed of one circular-arc-shaped member and one rectilinear member, such as a carabiner.
  • the ground wire 70 (270) may not be detachable from the yarn threading assisting tool 60.
  • the hook member 72 (272) may not be attachable to the frame 92.
  • ground wire 70 has a spring property (elasticity)
  • the ground wire 70 may not have a spring property (elasticity), on condition that the ground wire 70 can be attached to a position where the wire does not interfere with the yarns 10 when the yarn threading is not performed and the ground wire 70 is long enough for the yarn threading.
