Description

[Detailed description of the invention] The invention is based on attaching an elastic body capable of supporting the weft to the outside of the side wall of the shirttle. This invention relates to a shirt tortle that can reliably prevent the occurrence of cuts, etc.

When the shirttle that has been flying all the way is caught by the shirt box and suddenly stops its movement, the weft yarn let out from the shirt box becomes slack and gets caught between the front piece of the shelf board of the shirt box and the shirt l-le. Cheap.

Particularly in multi-shuttle looms, as shown in Figure 3,
0 moves up and down, as the shirttle 1 rises, the length of the weft 3 that is rubbed between the front piece 22 of the shelf board 21 and the shirttle 1 becomes longer (indicated by the dashed line in the figure). This may cause weft breakage, weft damage, weft stains, etc., and deteriorate the quality of the woven fabric.
Various problems have been pointed out in the past, such as a reduction in weaving efficiency.

The present invention aims to provide a shuttlecock that can solve these problems, and one embodiment thereof will be described below with reference to the drawings.

In the figure, the shirttle 1 of the present invention has an elastic body 5 affixed to the side wall W of the shirttle main body 2 and an elastic body 5 capable of supporting the weft 3.

The shuttlecock main body 2 has a boat shape, and a housing chamber 7 for housing a woodwind 6 is recessed in the center of the surface.
The side wall W is provided with an elongated groove 9 along its longitudinal direction, and a three-striped upper guide groove 11° into which the slider 10 can fit and slide on the upper and lower sides of the inner side of the groove 9. 11.11 and lower guide groove 1
2.12.12 is engraved.

Note that the slider 10 is always elastically pulled toward the end of the shuttlecock main body 2 by the elastic cord 13, and the slider 10
The tension of the weft yarn 3 led out through the guide hole 15 provided in the weft is kept constant.

Also, on the upper edge 16 of the side wall W outer surface S on the side of the lower guide groove 12.12.12 of the shirttle main body 2, there is a slightly outer position of the end 17 of the lower guide groove 12 located on the tip 2a side of the shirttle main body 2. A recess 19 is formed in the recess 19, which is a scoop-shaped notch having a relatively short length and a relatively shallow bottom.

The elastic body 5 is made by cutting an easily compressible material such as sponge-like rubber into a rectangular parallelepiped shape, and the negative corner portion 5a of the elastic body 5 is attached to the recessed portion 19 formed in the shirttle main body 2,
It projects slightly outward from the side wall W of the shuttlecock main body 2, and its upper end 5b is approximately equal in height to the upper edge 22a of the front piece 22 of the shelf board 21 of the drawer box 20.

Note that the height of the front piece 22 of the shelf board 21 is usually set to about half the thickness of the shirttle 1 so that the flying shirttle 1 can be stopped in a fixed position without difficulty. 5b is approximately equal to the height of the longitudinal center line of the groove 9, so that the weft yarn 3 let out from the guide hole 15 of the outermost slider 10a is supported by the elastic body 5 when sliding on the shelf board 21. be done.

On the other hand, during single flight, the weft yarn 3 easily comes off from the elastic body 5.

In addition, in FIG. 2, 23 is a well for pressing the shuttlecock 1 against the front piece 22 of the shelf board 21.

However, when the shuttlecock 1 is captured by the box 20, the second to third
As shown in the figure, the shirttle 1 is sandwiched between the front piece 22 of the shelf board 21 and the swell 23, and at this time the elastic body 5 is compressed to fill the gap g created between the front piece 22 and the shirttle 1. .

Therefore, the weft 3 can be supported by the upper end 5b of the elastic body 5,
The weft yarn 3 is surely prevented from being caught between the front piece 22 and the side wall W of the shirttle 1.

In addition, since the elastic body 5 is attached to the recessed part 19, even when the side wall W of the shirt seat 1 rubs against the front piece 22 of the shelf board 21,
The adhesive portion 5C does not rub against the front piece 22 at all, and there is no fear that the elastic body 5 will fall off.

Moreover, since the elastic body 5 is easily compressible, it deforms easily according to the front piece 22, filling the gap g, and can be immediately restored to its original shape, so that it can withstand repeated use.

Furthermore, since the elastic body 5 supports the weft yarn 3 in a soft manner, there is no risk of damaging the weft yarn 3.

As mentioned above, the shirttle of the present invention has an elastic body capable of supporting the weft attached to the outer side wall of the main body of the shirttle, and as a result, the shirttle can be pinched, cut, or damaged between the shelf board of the weft mold box and the shirttle. In addition, the possibility of staining can be completely avoided, and excellent effects can be achieved, such as improving the quality of the woven fabric and improving the efficiency of weaving.

The elastic body can be made of various materials as long as it is easily compressible, and depending on the type of weft used or the loom used, the elastic body may be placed on one side of the lower guide groove or on both ends of the lower guide groove. Can be pasted in position.

In addition, since it is only necessary that the weft can be prevented from being caught between the shirttle and the shelf board of the box by the attached elastic body, the recess can be placed at any position slightly to the side of the end of the lower guide groove. Can be shaped to any size.
