  For convenience of understanding, the first fixed guide 23A of the conveyor block 21 is numbered from the right to the left in the drawing, and the conveyor blocks 21 with the same numbers in FIGS. 4 to 8 indicate the same thing. ing. In the following description, the conveyor block [n] means the conveyor block 21 with the number n on the drawing. For example, the conveyor block [6] is the third conveyor block from the left in FIG. 21.

In the state shown in FIG. 4, three yarns T are sequentially wound around the first fixed guide 23A and the second fixed guide 23B.
The thread T, when viewed from the right side to the left side of the drawing, is engaged with the first fixed guide 23A in the conveyor block [0], and then passes between one belt-like member 14 and the inner cylindrical body 17, From the first fixed guide 23A side to the second fixed guide 23B side, it is engaged with the second fixed guide 23B in the conveyor blocks [1], [2] and [3].

It extends to the 23A side and engages with the first fixed guide 23A in the conveyor blocks [4], [5], and [6]. The cylindrical body turning roll 41 is located above the conveying surface of the conveyor block [5].

  The thread T is engaged with the first fixed guide 23A in the conveyor block [6], and then passes over the one belt-like member 14 and crosses from the first fixed guide 23A side to the second fixed guide 23B side. It is engaged with the second fixed guide 23B in [6]. Such engagement of the yarn T with the fixed guides 23A and 23B is realized by applying a tension to the yarn T by the yarn supply mechanism 32 disposed outside the second fixed guide 23B in the conveyor block [5]. Yes. Further, the yarn T is continuously supplied from the yarn supply mechanism 32.

The operation in this manufacturing method from the state shown in FIG. 4 to the next rotation of the annular rotating member 31 is described.
The conveyor 2 moves to the right in the drawing at a constant speed. The state shown in FIG. 5 is a state in which the transport conveyor 2 has moved to the right by three conveyor blocks from the state shown in FIG. During this time, the annular rotating member 31 does not rotate.

  As the transport conveyor 2 moves, as shown in FIG. 5, the thread T hooked behind the second fixed guide 23B in the conveyor block [6] is hooked in front of the second fixed guide 23B in the conveyor block [7]. . Then, the thread T arranged on one belt-like sheet 14 enters between the one belt-like sheet 14 and the inner tubular body 17 on the downstream side of the tubular body turning roll 41.

  When the conveyor 2 further moves to the right of the drawing by three conveyor blocks, the state shown in FIG. 5 is changed to the state shown in FIG. The thread T located between one belt-like sheet 14 and the inner cylindrical body 17 moves to the downstream side of the belt-like sheet turning roll 42.

In this state, as shown in FIGS. 7 and 8, the annular rotary member 31 is rotated 180 ° in plan view, and the yarn supply mechanism 32 is moved from the second fixed guide 23B side to the first fixed guide 23A side. A virtual circle C indicates the rotation locus of the yarn supply mechanism 32.
By the movement (rotation) of the yarn supply mechanism 32, the yarn T is engaged with the second fixed guide 23B in the conveyor block [9], and then crosses from the second fixed guide 23B side to the first fixed guide 23A side, Engage with the first fixed guide 23A in the block [10]. As a result, the thread T is disposed on the one belt-like sheet 14 and the inner tubular body 17 between the tubular body turning roll 41 and the belt-like sheet turning roll 42.

Further, as shown in FIG. 8, the annular rotating member 31 is rotated 180 ° in plan view, and the yarn supply mechanism 32 is moved from the first fixed guide 23A side to the second fixed guide 23B side.
By the movement (rotation) of the yarn supply mechanism 32, the yarn T is engaged with the first fixed guide 23A in the conveyor block [12], and then crosses from the first fixed guide 23A side to the second fixed guide 23B side. Engage with the second fixed guide 23B in the block [12]. As a result, the yarn T is disposed on one of the belt-like sheets 14 on the upstream side of the cylindrical body turning roll 41.

Through this operation, the thread T is engaged with the fixed guides 23A and 23B in the same state as shown in FIG.
Thereafter, by repeating the above-described operation, the yarn T is sequentially disposed on the upper surface side and the lower surface side of the inner cylindrical body 17 and wound around the inner cylindrical body 17. At the same time, the thread T is sequentially disposed between the upper surface of the inner cylindrical body 17 and the other band-shaped member 15 and between the lower surface of the inner cylindrical body 17 and the one band-shaped member 14.

  According to the method of manufacturing the hair holder of the present embodiment described above, the (inner) tubular body 17 is rotated with its longitudinal direction as the rotation axis, or the supply port of the thread T is set in the longitudinal direction of the inner tubular body 17. The thread T can be easily wound around the inner tubular body 17 in a state where the inner tubular body 17 is placed on the transport surface of the transport conveyor 2 without rotating as a rotation shaft.

  Moreover, according to the manufacturing method of the hair holding tool of this embodiment, by devising the supply form of the strip | belt-shaped sheets 14 and 15 to the conveyance conveyor 2 (before the inner side cylindrical body 17 is supplied to the conveyance conveyor 2). One belt-like sheet 14 is supplied to the conveyor 2, and the inner cylindrical body 17 is supplied to the conveyor 2, and then the other belt-like sheet 15 is supplied to the conveyor 2, etc.), as shown in FIG. It has an elongated double cylindrical structure, and includes an inner cylindrical body 17 and an outer cylindrical body 12 that is externally inserted into the cylindrical body 17, and the inner cylindrical body 17 and the outer cylindrical body are arranged on the outer peripheral surface of the inner cylindrical body 17. A winding thread 13 for winding the body 12 is wound in a spiral shape, and the outer cylindrical body is positioned at a position where the winding thread 13 is folded from one surface side of the inner cylindrical body 17 to the other surface side. Hair retainer exposed from 12 " It can be easily manufactured.

In the above description, the annular rotating member 31 performs only the rotational movement with the inner ring portion 31A as the rotation center. However, as described below, the annular rotating member 31 can also perform a linear movement along the conveying direction of the conveying conveyor 2. preferable.
The annular rotating member 31 moves in the transport direction (from the left side of the drawing to the right side) of the transport conveyor 2 during the rotation. When moving in this way, when the yarn supply mechanism 32 crosses between the first fixed guide 23A and the second fixed guide 23B, it becomes difficult for the yarn supply mechanism 32 and the fixed guides 23A and 23B to come into contact with each other.

Further, the annular rotating member 31 moves in the direction opposite to the conveying direction of the conveyor 2 (from the right side to the left side in the drawing) when the rotating member 31 is not rotating. When moving in this way, the movement of the yarn supply mechanism 32 in the conveyance direction of the conveyor 2 is canceled out, and the annular rotating member 31 is moved to the original position (in the present embodiment, the rotation of the annular rotating member 31 in plan view). The center will return to the position where it coincides with the cylindrical body rolling roll 41.
Such a configuration in which the annular rotating member 31 moves in the direction opposite to the conveying direction of the conveyor 2 when not rotating is particularly effective when the conveyor pitch (interval between fixed guides adjacent in the longitudinal direction) is narrow. is there.
