金を示す。Embodiments of the present invention will be described below with reference to the accompanying drawings. First, in FIG. 2, an adhesive 30 is applied to a part of the slit groove 10 formed in the first projecting portion 6 of the needle plate 2, and the sewing needle 1 is pushed in from above, whereby the sewing needle 1, 1 is slit. Fix so that it does not fall out of the groove 10. The place where the adhesive 30 is applied is not necessarily the first projecting portion 6.
Of course, not only a part of the slit groove 10 but also a half of the entire length of the slit groove 10 may be used. next,
Another embodiment will be described with reference to FIGS. In the present embodiment, when the needle plate 2 is stamped and formed, a projection 32 is formed in the middle of the slit grooves 10, 10, and the sewing needles 1, 1 are engaged in the slit grooves 10, 10. The projection 32 is crushed by applying an impact from above to the projection 32.
The upper part of the sewing needles 1 and 1 is covered with the crushed part 33 of 2 and fixed so that the sewing needles 1 and 1 do not fall off (FIG. 4). At this time, the crushed portion 33 of the projection 32 is
On the slit grooves 10 on both sides of the
As it enters the gap between the needles 1 and 1, it is put on the surface of the needle plate 2
There is no rise and smooth cloth feeding is ensured.
You . At this time, an adhesive may be applied to the slit grooves 10 and 10 in advance. FIG. 5 is a schematic perspective view showing a state in which the needle plate 2 according to the present invention is assembled to the overlock sewing machine. In the drawing, reference numeral 26 denotes a lower knife, 24 denotes an upper knife, and 28 denotes a presser foot.

ぬけ落ちない等の効果がある。According to the present invention, a sewing needle is fixed with an adhesive into a slit groove formed on a side of a needle plate of an overlock sewing machine which receives a cloth to be fed.
Since the sewing needle flat crushed kick was formed in the center of the two slit grooves formed on the side projections are fixed configuration the needle plate, it is possible to cause swelling on the surface of the needle plate
In addition, there is an effect that the sewing needle does not fall off the needle plate due to the tension or external force of the thread when performing the overlock sewing after ensuring the smooth cloth feed .
