構成されていた。(Prior art) As a device for absorbing the slack in the weft yarns that occurs due to the reciprocating movement of the shuttle or the vertical movement of the shuttle box during weaving, a weft yarn system using a play piece that fits into a sliding groove provided on the side surface of the shuttlecock is used. Tension adjustment devices are often used, and conventionally the play piece is formed in the shape of a rectangular plate as shown in FIGS.
The structure is such that the tension of the weft yarn e, which is always drawn toward the end direction c of the shuttle and drawn out by passing through the yarn guiding hole d from the inside to the outside, is adjusted.

問題を生ぜしめることともなつていた。(Problem to be solved by the invention) Therefore, when the shuttle is temporarily stopped during weaving and is inserted again, or when the shuttle box moves up and down, the slack part of the weft f
However, it becomes extremely unstable due to impact during the shuttle throwing motion, etc., and the slack portion f sometimes gets stuck in the upper or lower sliding grooves h, h at a position near the side of the playlock g, The weft e passes between the groove bottom i of the sliding groove h and the play piece g, and as shown in FIG. e will be caught on the side of play child g. In such a state, it is no longer possible to pull out the weft e, and weft breakage occurs. As a result, it requires considerable skill and a great deal of effort to repair the damaged part of the woven fabric every time the weft is cut.
During this time, the loom must be stopped, resulting in a significant drop in weaving efficiency. Furthermore, when the loom is restarted, weaving steps and the like occur, resulting in a deterioration in the quality of the woven fabric. A conventional method for solving this problem is to adjust the length of the sliding groove h so that the slack portion f is difficult to pass between the groove bottom i of the sliding groove h and the play piece g.
The aim was to make the groove depth as deep as possible.
However, due to the dimensional constraints of the shuttle, the depth of the groove was limited to approximately 3 mm at most, and it was still impossible to reliably prevent the weft threads from passing through. The longer the time, the more the strength of the shuttle deteriorates, which is a serious problem.

たのである。 The present inventor believes that if the weft yarn that has passed between the groove bottom and the playr is configured so that it passes between the groove bottom and the play element from the inside to the outside again, the weft yarn will return to its normal state and the weft thread will return to its normal state. We believed that this would reliably prevent weft breakage, and that it would also be possible to improve the strength of the shuttle without increasing the depth of the sliding groove, and as a result of further research, we arrived at this invention. be.

質の低下を来さない。 Next, the play piece 6 in the shuttle according to this embodiment
The operation will be explained based on FIGS. 3a, b, c, and d, taking the case of the lower sliding groove 5 as an example.
That is, due to the impact during the shuttle throwing motion, the weft thread 1
The slack portion 20 of 5 fits into the sliding groove 5 in the vicinity of the side of the play piece 6 (as shown in FIG. 3a),
When the weft yarn 15 passes between the groove bottom 21 of the sliding groove 5 and the play piece 6 from the outside to the inside, as shown in FIG.
As shown in the figure, the weft 15 is once in contact with the peripheral part 22 of the play child 6, but as the shuttle 1 flies, the play child 6 is rotated in the direction of arrow F by the weft thread 15, and as a result, The contact portion 23 between the play piece 6 and the weft thread 15 moves to the groove bottom 21 side, and the weft thread passed through from the inside to the outside between the groove bottom 21 and the play piece 6 (see Fig. 3 d), and quickly Return to normal state. Moreover, even if the play piece 6 rotates when the weft thread 15 goes around, the position of the pivot hole 10 is set so that the pivot hole 10 does not fit into the sliding groove 5, as described above, and Since the branch 17 and the peripheral edge 19 of the pivot hole 10 are in contact with each other so as to slide relatively, the peripheral edge of the play piece 6, the weft 15 and the pivot piece (in this embodiment, the elastic string) Part) 1
2 can be prevented from simultaneously overlapping in the sliding groove 5, and therefore there is no risk of cutting the weft yarn 15, and there is no possibility of unsmooth pulling out of the weft yarn during the turning. No deterioration in woven fabric quality.

なる等製織物の組織くずれを生ずることとなる。 By the way, as shown in FIGS. 4a and 4b, if the disc-shaped play child is tied to the elastic string 25 in the same manner as in the case of the conventional play child, the sliding groove 5
When the weft yarn that has passed between the groove bottom 21 and the play child passes from the outside to the inside, as shown in FIG. 4b,
The peripheral edge part 26 of the play child, the weft 15 and the binding part 27 of the elastic string overlap at the same time in the sliding groove 5 to form the weft 15.
becomes stuck. As a result, unnecessary tension is applied to the weft threads pulled out from the shuttle, making the draw-out of the weft threads unsmooth, resulting in irregular radial density and deformation of the weft fabric.

and upper, middle, and lower three pivot holes 10a, 10b, 1
0c is provided. In this way, multiple pivot holes 1
0 is provided because there are cases where it is better to change the height of the weft yarn 15 pulled out from the yarn guiding hole 9 depending on the diameter yarn, the position of the heald, or the type of fabric. If it is better to pull out the weft thread 15 from above, use the upper pivot hole 10a as shown in Fig. 6 and pull out the weft thread 15 from below. If this is the case, insert the lower pivot hole 1 as shown in Figure 7.
Use 0c. Further, in FIG. 6, an elastic string 13 is attached to a pivot piece 12 formed by bending a wire or the like into an annular shape.
The case where the two are combined is shown.

設位置は任意である。 Furthermore, as shown in FIG. 8, the thread guide hole 9 may be formed by fixing a thread guide ring member 29 made of ceramic, pottery, or the like to the prepared hole. Furthermore, it is better to arrange the pivot hole 10 at the center of the playr main body 7 or in its vicinity.
This is preferable in order to smooth the rotation of the weft yarn 15, but the condition is that the rotation of the playr 6 when the weft thread 15 goes around is performed smoothly and that the pivot piece 12 does not fit into the sliding groove 5 when the playback rotates. The arrangement position of the pivot hole 10 is arbitrary as long as the following is satisfied.

A play child 6 formed in the shape of a disk is shown, which is integrally surrounded by a material such as a slightly thin resin (the same material as the material of conventional play children). In the figure, the pivot piece 12 is formed in a hook shape, and an elastic string 13 is tied to the pivot piece 12.

幅に向上されたものとなされうる。(Effect of the invention) As a result of the play child of the invention being constructed as described above,
Even if the weft thread passes between the groove bottom of the sliding groove and the play child due to the weft slack phenomenon, the passed weft thread easily and quickly returns to its normal state. Therefore, it is possible to reliably avoid accidents of weft thread breakage caused by weft threads being passed through, and there is no situation in which the weft threads are not pulled out smoothly when the weft threads are threaded, thereby improving weaving efficiency and fabrics. It can be expected to improve quality. In addition, since the weft thread is threaded smoothly and quickly, there is no need to consider the weft thread threading as a particular problem. Therefore, it is sufficient to set the groove depth of the sliding groove to a level that can prevent the player from coming off, for example, about 1 mm. This depth is much shallower than the groove depth (approximately 3 mm) in the conventional shuttle described above, and as a result, the strength of the shuttle of the present invention can be greatly improved.
