縫いを可能とする針板の構成を提供するものである。However, using the sewing needle 1 of the above-mentioned conventional example, two vertically moving linear needles (not shown) having sewing threads attached thereto, the overedging looper 20 and the double chain stitch looper are used. In cooperation with 22, a so-called two-needle, four-thread overlock seam is formed. The sewing thread of the linear needle and the sewing thread attached to the overedging looper 20 and the looper for double chain stitch 22 are wound around the gaps 17 and 16 to the tip of the sewing needle 1 to form an overlock stitch.
Due to the tension or external force of the sewing thread used, the sewing needle 1
Has fallen out of the slit groove 10 and the seams cannot be formed. Therefore, the present invention provides a construction of a needle plate which prevents the sewing needle 1 from falling off the slit groove 10 and enables smooth overlock sewing.

え金を示す。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to the accompanying drawings. First, in FIG. 2, the adhesive 30 is applied to a part of the slit groove 10 formed in the first protruding portion 6 of the needle plate 2, and the sewing needle 1 is pushed in from above to slit the sewing needles 1 and 1. Fix it so that it will not fall out of the groove 10. Needless to say, the portion to which the adhesive 30 is applied is not necessarily limited to a part of the slit groove 10 of the first protruding portion 6 and one 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 punched and formed, a protrusion 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 and at the same time. Impact the protrusion 32 from above and crush it,
The crushed portion 33 of 2 fixes the upper surface of the sewing needle 1, 1 so that the covering needle 1, 1 does not fall off (FIG. 4). At this time, an adhesive may be applied in advance to the slit grooves 10, 10. FIG. 5 is a schematic line perspective view showing a state where the needle plate 2 according to the present invention is assembled to an overlock sewing machine. In the drawing, reference numeral 26 is a lower knife, 24 is an upper knife, and 28 is a presser foot.
