At this time, the plurality of yarns 10 on each roller are hung in a bundled state as shown in FIG. After threading the five heating rollers 4 a to 4 e and the plurality of yarn feeding rollers 11, 12, 16, and 17, the operator places the suction gun 24 on the floor surface.

  Next, the yarn dividing operation is performed on the plurality of yarn dividing guides 19 to 22 in order from the one arranged on the upstream side (first yarn dividing step of the present invention). Here, the yarn hooking on each of the yarn dividing guides 19 to 22 is performed using a yarn hooking auxiliary tool 25 as shown in FIGS. As shown in FIG. 6, the yarn hooking auxiliary tool 25 includes a number of grooves 25 a that hold the plurality of yarns 10. When the plurality of yarns 10 are hung on the yarn hooking aid 25, the yarn hooking aid 25 is inserted into the traveling yarns 10, and the plurality of yarns 10 are respectively hung on the plurality of grooves 25a and held.

  First, as shown by the arrows in FIG. 6, the yarn separation guide 18 is locked in a state where the first posture is switched from the first posture to the second posture, and the plurality of yarns 10 hanging on the yarn separation guide 19 are separated. In the yarn dividing guide 19, a plurality of guide pieces 19a for accommodating the yarn 10 are arranged in the front-rear direction. Therefore, by switching the yarn dividing guide 18 from the first posture to the second posture, the arrangement direction of the plurality of guide pieces 18b provided in the yarn dividing guide 18 and the plurality of guide pieces 19a provided in the yarn dividing guide 19 are set. Can be made to coincide with the arrangement direction. Therefore, it is easy to change the arrangement direction of the plurality of yarns 10 to the axial direction of the yarn feeding roller 16. Since the plurality of yarns 10 have already been separated on the yarn dividing guide 18, as shown in FIG. 6, by inserting and operating the yarn hooking auxiliary tool 25 on the plurality of yarns 10, the yarn dividing guide 19 is operated. A plurality of yarns 10 held in a bundle are accommodated one by one in the yarn accommodation space S (see FIG. 3) in one yarn accommodation space S between the guide pieces 19a. Thus, the plurality of yarns 10 can be separated by the yarn separation guide 18.

  Next, as shown by the arrow in FIG. 7, the yarn separation guide 18 is switched from the second posture to the first posture and locked. At this time, the bar guide 27 provided in the yarn dividing guide 18 also turns together with the yarn dividing guide 18 and is arranged on the front side of the plurality of yarns 10. Thereby, the movement to the front direction of the some thread | yarn 10 is controlled.

  As shown in FIG. 8, the arrangement interval of the plurality of yarns 10 is determined by the yarn dividing guide 19 located on the upstream side, so that a plurality of the plurality of heating rollers 4 a to 4 e provided in the heat insulating box 26 are hung. The arrangement interval of the yarns 10 is stabilized following the interval of the yarns 10 on the yarn dividing guide 19. As a result, the arrangement interval of the plurality of yarns 10 coming out of the slits 26c is stabilized, so that the yarn separation guide is used by a portion that is operated by an operator and does not have the bar guide (not shown) or the groove 25a of the yarn hooking auxiliary tool 25. Since the yarn 10 follows the yarn pitch regulated by the yarn dividing guide 19 simply by lifting the yarn 10 on the yarn 20 from the yarn dividing guide 20, the yarn can be easily divided into the yarn dividing guide 20.

  Next, the operator separates the yarn 10 on the yarn separation guide 21 arranged between the yarn feeding roller 17 and the yarn feeding roller 11 as shown in FIG. At this time, the operator inserts the yarn hooking assisting tool 25 into the plurality of yarns 10 traveling immediately below the yarn feed roller 17 from the left side. Further, while holding the plurality of yarns 10, the yarn hooking auxiliary tool 25 is moved downward while rotating 90 ° toward the front side, and the arrangement direction of the plurality of yarns 10 is made to coincide with the left-right direction. Thereby, the arrangement direction of the plurality of guide pieces 21a provided in the yarn dividing guide 21 and the arrangement direction of the plurality of yarns 10 traveling on the upstream side in the yarn traveling direction can be matched. Therefore, the yarn hooking aid 25 can easily separate the yarn 10 on the yarn dividing guide 21. At this time, the plurality of yarns 10 traveling between the yarn feeding roller 17 and the yarn feeding roller 11 are twisted by 90 °.

  Next, an operator operates a plurality of yarns 10 that travel between the yarn feeding roller 11 and the yarn feeding roller 12 and a portion without a bar guide (not shown) or the groove 25a of the yarn hooking auxiliary tool 25 is operated. By using the yarn 10 to float from the yarn dividing guide 22, the yarn 10 on the yarn dividing guide 22 follows the yarn pitch of the yarn dividing guide 21, so that the yarn can be easily divided into the yarn dividing guide 22. At this time, the yarn dividing operation to the interlace 23 can be performed in the same procedure as the yarn dividing of the yarn dividing guide 22, but can be switched between a position where the yarn enters the interlace 23 and a position where the yarn does not interfere with the yarn path. A bar guide (not shown) is provided in the vicinity of the interlace 23, and the bar guide is threaded in a state where the bar guide is in a position where the entry of the yarn is inhibited. The yarns 10 can be separated into the interlaces 23 only by retracting the guides.

  In the present embodiment, the operator separates the yarn into the yarn dividing guide 18, hooks the yarn, and then operates the suction gun 24 so that the plurality of yarns 10 before the yarn separation are applied to all the yarn feeding rollers 11, 12, 16, and 17. Thread it all at once. At this time, the plurality of yarns 10 held by the suction gun 24 form a single bundle. Therefore, the operator can easily thread the yarn feeding rollers 11, 12, 16, and 17.

  Thereafter, the suction gun 24 is placed on the floor, and the yarn 10 on each of the yarn dividing guides 19 to 22 is divided into yarns, so that the yarns 10 on the yarn feeding rollers 11, 12, 16, 17 are separated. . That is, the operator does not need to perform a fine operation of hanging the yarn 10 on the yarn dividing guides 19 to 22 one by one while holding the heavy suction gun 24, and the yarn applying operation to the yarn dividing guides 19 to 22, that is, The yarn 10 on each roller can be separated. Therefore, threading and threading work are facilitated, and the time required for the work can be shortened.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments and examples, and various design changes can be made as long as they are described in the claims. is there.

For example, as described in JP2012-214941A, JP2013-231307A, and WO2011009498A, a plurality of yarns 10 can be fed by a yarn feeding roller without being arranged upstream of the heating roller. It may be configured to be wound around the heating roller without using a roller.

  The yarn dividing guides 18 to 22 may be any one as long as the position of each yarn 10 can be regulated. The yarn dividing guides 18 to 22 may be, for example, a comb-shaped integrated guide, a grooved roller-shaped guide, or a single yarn guide such as a dog tail guide.

  Further, for example, as long as the yarn dividing guide 18 does not interfere with the yarn path, the yarn dividing guide 18 may be arranged in parallel to the longitudinal direction of the yarn dividing guide 19 and fixed so as not to be turned.
