Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to an improvement of a guide needle for a coal-stretching machine.

<Prior Art> As a type of variable weave, there is a type of coal-woven fabric in which the spacing between pile ridges is widened to create a large ground structure. When this fabric is piled with a conventional guide needle, the pile is simply cut and divided into two parts, and the pile becomes abnormally long depending on the rib spacing, making it impossible to obtain the desired fabric.

<Problems to be Solved and Means for Solving> The present invention aims to eliminate this drawback and provide a guide needle for a coal-stripe machine that can be used to pile the fibers to produce the above-mentioned coal-stripe fabric. , is configured as follows. That is, it is a guide needle for a coal top-strapping machine, in which the upper half is bifurcated to form a pair of needle parts, and cut grooves into which the hair-shafting machine cutters are inserted are provided in the longitudinal direction of both needle parts.

<Examples> Examples of the present invention will be described below based on the drawings. FIG. 1 is a plan view showing the introducer needle 1 of the present invention.
A pair of needle parts 3, 3 with the upper half of the filament 2 in a bifurcated shape
A cutter groove 4 is provided in the central length direction of both needle parts 3, 3, into which a cutter (not shown) of a Cole top-hairing machine is inserted.

To use this, when the interval between the pile ridges is relatively short, that is, in a fabric in which the floating weft threads 5 of one structure are short as shown in FIG. A real guide needle 1 is inserted and two cutters 6, 6 are guided between one tissue. Then, as shown in FIG. 5, the floating weft thread 5 of one structure is cut at two places, and the floating weft thread 51 between the cutters 6 is separated and removed. The floating weft yarn 5 at the portion where it intersects with the warp yarn 7 remains as a pile 8.

Next, when the interval between the pile ridges is long, that is, in a fabric with long floating weft yarns 5 as shown in FIG. 6, the guide needle 1 is inserted so that the cutters 6, 6 are inserted to the left and right of the intersection point 7 with the warp yarns. Then, as shown in FIG. 7, the floating weft threads 5 are cut on the left and right sides of the intersection point 7 with the warp threads, and the floating weft threads 51 between the adjacent guiding needles 1 are lifted and removed. As in the previous example, the floating weft yarns at the 7 points of intersection with the warp yarns remain as piles 8.

<Effects of the Invention> As explained above, the present invention constitutes a guide needle having a pair of needle parts, each of which functions as a guide needle. For this reason, the guide needle for the coal top-strapping machine has the special effect of being able to cut the pile short even if the spacing between the pile ridges is long.
