Description

[Detailed explanation of the invention] Conventionally, when weaving two weft threads in parallel during weaving, two weft threads are drawn in advance on a wooden tube in a shuttle using a tube winding machine, wound up into a tube, and then inserted into the shuttle. Weaving was done by passing the weft threads through two playpieces, or by pulling out the weft threads from two woodwinds placed opposite each other in the same shuttle and aligning them and passing them through one playpiece. The two weft threads become entangled with each other, resulting in slight twists, which often impairs the texture of the fabric.

The present invention provides a shuttle that completely eliminates the entanglement of the weft threads and allows weaving with two weft threads neatly aligned. By providing individual playpieces and pulling out the weft threads pulled out from the two wood pipes from the shuttle separately via the individual playchildren, the individual weft threads are inserted while maintaining a state in which they do not intersect, and the two weft threads become entangled. The gist of this is to prevent the generation of heat.

An embodiment of the present invention will be described below with reference to the drawings.

In Figures 1 and 2, the shuttle body,
, are woodwinds, and , are shuttle tongs, each of which allows two woodwinds to be mounted facing each other in the same shuttle body.

, are the sliding grooves of the playpiece, each of which has three rows of grooves on the top and bottom, and each sliding groove has a through hole, , , , , respectively, as shown in Fig. 3.
, , , are arranged sequentially from the inner groove to the outer groove, and each playable slides freely from side to side along the sliding groove while receiving tension adjustment by elastic strings, , , ,. It's getting old. This elastic string is made of a rubber elastic material, and in order to have a wide elastic range, it uses a pulley...
The elastic cord can be worn for a long time.

Note that A and B are two types of weft threads wound around the woodwind respectively.

The principle and structure in which the weft wound around one of the woodwinds is pulled out from the shuttle through the playpiece is the same as that of conventional shuttles, but the present invention combines two woodwinds into one shuttle as described above. By placing the weft yarns A and B facing each other and pulling out the respective weft yarns A and B through separate play pieces, the individual weft yarns can be aligned and inserted without crossing each other.

That is, in the two-line alignment shuttle according to the present invention, as shown in Fig. 3, a certain tension is applied to the weft thread pulled out from the woodwind via the tension pin, and the weft thread passes through the hole in the play child and is pulled by the elastic string. The tension is adjusted, and then the tension is adjusted again using the play piece, and the weft is pulled out of the shuttle.

Similarly, the weft yarn B pulled out from the other wood tube installed symmetrically with the wood tube is also pulled out of the shuttle while adjusting the tension in the same manner as described above. Since the shuttle is pulled out separately from the through hole of the play child, when the shuttle is placed in the shuttle box (not shown), a constant angle θ is maintained, and the weft threads are twisted in the middle of the weft thread. It is possible to type the two side by side.

In Fig. 3, the weft threads ′ and ′ indicated by broken lines show the state when the shuttle is stored in the shuttle box (not shown) on the opposite side, and in this case also, the angle θ is maintained symmetrically with the above. It is.

Therefore, when using the shuttle according to the present invention, the two weft threads are driven into the fabric while maintaining the angle θ in both the right-hand and left-hand travel, so the weft threads driven into the fabric are ,,,,,,,
, etc. The fabric is woven in a regular arrangement of every two strands without twisting, making it possible to weave fabrics that cannot be obtained with conventional shuttles.

Although the structure of this invention is simple as mentioned above, the effect obtained by this method is that the two strands are never twisted, which is revolutionary in the weaving industry and is suitable for industrial use. It is highly sexual.
