The needles 6L, 6M, and 6R are supplied to a plurality of needles (representing j) needles 5L, 5M, and 5R (which are juxtaposed in the box, and τ is in the direction in which the feeding directions are crossed), by eliminating the need for a needle. The line cutting device of the well-known line is placed under the pressing member (4), and the needle thread 6l, _ end portion 61, 6m, 6r after (4) is moved to the side of the side of the needle 5L, 5M, 5R, as the case may be. Parts 61, 0m, όι* are separated by a needle thread (wiper, as explained hereinafter) (4), which is slightly horizontally moved on the right side of the cloth, and blocks the hole of the cloth. . At this time, the relationship between the needle thread 6R inserted into the pinhole of the right end pin and the upper decorative wire 3 in the parallel stitches 5l, 5m, and 5r is as shown in (10), and the end portion 6r of the right end needle thread 6R is free end. The state is located behind the upper side line 3, that is, the direction in which the cloth 2 is transferred and the rear side. When the sewing machine is operated in this state and the sewing of the next cloth 20 is started, as shown in Fig. 7 (8), the upper decorative thread hook H is retracted from the position of the entrance and exit end, and is attached to the needle fixing member 7. The upper decorative lane 8 moves synchronously with the needle and π, and then, as shown in Fig. 7(c), the upper T-wire hook 1 reaches the retracted end, and the needles 5L, 5M, and 5 are moved in the opposite direction. And the needles 5L, 5M, 5R and the upper decorative lane 8 reach the bottom dead center and then move up. At this time, the end portions Μ, 6r of the needle threads 6L, 6M, and 6R (cut under the pressing member, or moved to the side of the needle 5B, 5M, and 5r) are located in the pressing member. The top is free from tension, so as shown in Fig. 9(B), the free ends 61, 6m, and 6r of the needles 6L, 6M, and 6R are pulled to the upper side with the lower needles 5L, 5M, and 5 feet. Below the tensioning position of line 3. Next, when the upper decorative thread hook 1 moves in and out, there is no problem if the upper line 3 can be hooked by the fishing line portion la, but actually, the needles 5L, 5M, 5R and the upper decorative thread hook i The relationship of the timing of the action (set so that it can form a good stitch), the upper decorative lane 8 has risen before the hook line portion 1 is hooked on the upper decorative line 3, and since the upper _ side decorative lane When the 8 is raised, the upper decorative line 3 portion is pulled up to the upper side of the movement path of the hook line portion 1 a of the upper decorative thread hook 1 as shown in Fig. 7 (c), so the upper decorative line 3 portion cannot be hooked. In the hook line portion 1 a of the upper decorative wire hook, or even if it can be hooked, the probability of hooking is very unstable. When the upper decorative thread hook 1 reaches the entrance and exit end, as shown in Fig. 7(D) As shown, the upper decorative wire loop cannot be formed between the hook line portion 1a and the upper decorative wire guide 2, and the end portion of the right end needle thread 6R is accompanied by the rise of the needles 5L, 5M, 5R as shown in Fig. 9(C). As shown in the figure, the needle is pulled down to the lower portion of the upper decorative line 3, and is caught by the needle of the lower hook line hook 19 Line 6R 8 200840900 The end portion 6r is located in front of the upper decorative line 3. Further, in order to make the state of the figure clearer, the enlarged state of Fig. 7(D) is shown in Fig. 8. In the state shown in Fig. 8, even if the needles 5L, 5M, and 5R are lowered, the end portions 6 of the needle threads 6L, 6M, and 6R are 6m, and the lower portion of the presser member is connected to the cloth 20 to be held, and the upper side is decorated. The line 3 continues to maintain the vicinity of the end portions 6i, 6m of the needle thread 6L, 6M at the left end, and is located at the rear end of the right end R, and cannot be borrowed when the lower-second needle 5L, 5M, 5R^ is moved downward. The upper decorative thread 3 portion 7 is pressed down the pressing member by the right end needle thread 6R. Therefore, although the stitches of the needle thread 6L, 6M, and 6R and the lower thread can be formed, the sewing operation of the upper side is not formed, and the sewing operation of the stitching action is followed by the stitching of the second stitch. The problem of defective products.
