As shown in the second to fourth figures, the yarn dividing n 21 includes the fishing line portions 22 and 2 for the first upper thread and the second upper decorative thread closer to the front end side of the yarn splitter than the thread hook portion 22. The wire hook portion 23' is formed to swing with the swing shaft 8 as a center by the swinging of the swing arm 18, so that the first and second wire hook portions 22 are adjacent to the upper needles 16a, 16b, 16c. The side moves back and forth in the left and right direction of the figure. That is, the first line hook portion 22 is formed when the yarn splitter 2 is reciprocating in the left-right direction on the front side of the upper needles 16a, 16b, 16c from the right dead point to the left dead point. 5th and 1st, the right side of the right needle i6a passes over the right needle 16a and moves back through the middle needle 16b to the position of the left position of the left needle i6c, and the second line hook portion 23 is from the fifth And the right side of the right needle Ua of the 苐1〇 is moved back and forth in the left-right direction between the range of the second needle 16a, the needle 16b, and the second needle 16c. 201215729 The swing arm 19 is coupled to the swing arm 28 coupled to the vehicle 27 by a connecting rod 30 which is rotatably supported by the bracket 25 supported by the front end 7 in parallel with the swing shaft 8. Thereby, the swing of the swing shaft 8 is transmitted to the swing arm 19, and the shaft 27 is swung by the link 30 and the swing arm 28. The mechanism for transmitting the swing of the swing shaft 8 to the shaft 27 may be replaced by any other transmission mechanism. A lead piece 32 having a pinhole 33 and a table 26 are attached to the shaft 27, and a vertical dressing portion in which the bent lead pin 34 is inserted is attached to the stage 26. It is formed that the lead piece 32 and the lead pin 34 are swung around the shaft 27 on the yarn splitter, and the eye 33 of the lead piece 32 is in the position of the fifth figure from the right oblique front of the right hand 16a. The range between the position of the second figure on the right side of the right needle i 6a is advanced and retracted, and the needle eye 35 at the front end of the wire needle 34 is at the position from the fifth figure in front of the right needle 16a and enters the right needle 16a and its phase. The target between the positions of the second figure between the needles 6b is advancing and retreating. In the figure i, the symbol 37 is attached to the wire guide bow of the machine. The eyelet 33 of the lead piece 32 and the eyelet 35 of the lead pin 34 are formed as circular holes in the illustrated example, but the long hole which may be an oblong shape may also be a grooved pin eye as shown in FIG. . Further, in the illustrated example, the needle eyes are formed to penetrate vertically, but may be formed in a horizontal direction. As described above, the lead piece 32 and the lead pin 34 are advanced and retracted in the front-rear direction, and the rocker arm shaft 4, the link mechanism 丨3, the swing shaft 8, the swing arm 9, the link 30, the swing arm 28, and the shaft 27 The table 26 and the like constitute an actuating mechanism for advancing and retracting the wire 3 2 and the wire pin 34, but it is arranged with the reciprocating mechanism for swinging the yarn splitter 201215729 21 to the left and right, that is, by the rocker car, and the r mechanism (1) The mechanism of the shaft 8 and the swing arm 18 is a common portion from the mechanism of the rocker arm: 4 to the swing shaft 8, and the shaft of the lead wire 8 and the wire pin 34 are used as the common swing shaft. In order to make the two-way reciprocating motion of the revolving motion, the mechanism for reciprocating the lead piece 32 and the lead wire 34 is the same as the above-described swinging mechanism, and may be used as a mechanism for straightening and linear motion. In addition, the swinging mechanism of the lead wire #32 and the wire pin 34 is not limited to the swinging mechanism of the above embodiment, and other known swinging mechanisms may be employed. With regard to such a known swinging mechanism, for example, The operation of the wire needle disclosed in the above Patent Document 1 is used. In the above embodiment, the lead piece 32 and the lead wire 34 are oscillated around the shaft 27, but they can be reciprocated by separate actuating mechanisms that act in conjunction with the main shaft. The lead piece 32 and the lead pin 34 are moved at the optimal timing and the best. The needle plate 36 under the head is attached to the base not shown, and the 8th to the base under the needle plate is disposed. The yarn splitter 38 shown in Fig. 12. The yarn splitter 38 is threaded through the yarn splitter line 39, as is generally known, which is synchronized with the upper and lower needles 16a, 16b, 16c. The right and left movement of the cloth in the direction of the right and the circular motion of the movement before and after the feeding direction are performed, and the needles 41a, 41b, 41c and the yarn separator line, which will be described later, are operated in cooperation with the upper needles 16a, 16b, and 16c. 39 The joint forming action of the seam is formed. -10- 201215729 ping: The sewing machine is constructed as described above, and when it is carried out on the fabric, first, the needle passes the needles 41a, 41b, 41e through the respective needles '^, C' And passing the first upper wire 43a through the eyelet m of the wire piece 32, the upper=upper line 43b The needle eye 35 at the front end of the needle 34 is passed through the yarn splitter 38 to start sewing the cloth. The second to twelfth figures of the knife show the seam forming process during the sewing process, at this time, the upper needle 16a, 16b, 16c are raised on the fabric to be at the top dead center, and the yarn splitter 21 is advanced in front of the upper needles 16a, 16b, i6c to hook the first and second upper trim wires 43a and 43b to the first And the second wire hook portions 22 and 23, and pulling the upper trim wires 43a, 43b to be located near the left dead point, and the wire piece 32 advances from the first pin formed by the right needle 16 a in the upper needle The needle thread trace of the row extends so that the needle eye 3 3 through which the first upper trim line 4 3 a is hooked against the first line fishing line is located near the front end of the right needle 16 6 right side, and the wire The needle 34 is advanced to extend from the needle thread trace of the second row formed by the middle needle 16b such that the eyelet 35 through which the second upper trimming line 43b hooked against the second thread hook portion 23 is located By the vicinity of the forward end between the right needle 16a and the middle needle 16b (Fig. 2). When the upper needles 16a, 16b, 16c start to descend from this state, the yarn splitter 2 1 reaches the left dead point of the forward end, and the lead piece 32 and the wire lead 34 reach the forward end. When the upper needles 16a, 16b, 16c are further lowered, the yarn splitter 2 1 starts to retreat toward the right side from the left dead point, while the wire piece 3 2 and the wire needle 3 4 are turned toward the front side and start to retreat, and the left needle 16 c extends from the stitching of the second row formed by the middle needle 16b, and descends vertically to the second upper trimming line 4 3b and the yarn splitter 2 1 hooked on the second thread hook portion 2 of the shai Between (Figure 8). -11 - 201215729 When the upper needles 43a, 43b are cut 2 1 continue to the figure Continue to the front side Down to the hooked eye 35: The needle 16a forms the first line of fishing Figure 3). On the right side of the upper needle map, the second upper trim 2 1 and then the retreat needle 3 4, and in the other side of the hanging side (Fig. 9), by loosening the line, but borrowing 1 to absorb the loose And the wire 21 is reached (the right front side of the upper needle retracting end is rotated and I is disengaged from the second wire hook portion 23 and is rotated by the front side and retracted by the left needle 1 6 c. , (10), 16C, when the step is further down, in the state in which the upper thread is sinned on each of the fishing units 22 and 23, the right side of the yarn splitter is retracted, and the wire piece 32 and the wire needle 34 are retreated backward, and The left needle 16c pierces the cloth w, and the middle needle rests on the second wire hook portion 23 and reaches between the needle two upper thread 43b of the wire needle 34 and the yarn splitter 21, and from the right side of the line The stitching stitches extend m to ^ between the first upper trim line 433 and the yarn splitter 21 on the portion 22 (i6a, 16b, 16C are further lowered), the yarn splitter 2i and the lead piece 32" 34it—step continues to retreat when the line 43b borrows the yarn splitter in the state of the left needle l6c_circle, but is pulled by the guide to absorb the slack 16b to the front of the first-top, 43a is retracted from the first-line fishing portion 22 after being wound around the middle needle (10), and is retracted by the white lead piece 32 on the front side and retracted to be retracted. At the same time, the right needle 16a is lowered to Around the middle needle 16b, the first upper trim line 43 & and the yarn splitter 4 of the eye 33 of the loop 32. When the 16a, 16b, 16c reaches the bottom dead center, the yarn splitter 21 approaches at the dead point, and the wire needle 34 and the lead piece 32 are also in the vicinity of the sin. The second upper trim line 43b is hooked on the left -12-201215729 needle 16c, and the guide 34 is turned toward the front side by traversing the top of the yarn splitter. Retreating, riding on the yarn splitter and being tensioned, in terms of the first upper thread 43a being hooked on the middle needle, and in the state of the yarn splitter 21, by guiding the guide piece 32 toward the front After the side is tightened (Fig. 10). When the upper needles 16a, 16b, 16c rise from the top dead center, the device 2丨 reaches the right dead point, and the wire needle 34 and the wire piece 32 reach the second end. (Fig. 5). Thereby, the second upper decorative thread is further pulled toward the front side in the state of riding the special yarn β 21, and the upper decorative line 43a is also formed by the right needle 16a. The needle is pulled out toward the front side (Fig. 1 1). When the upper needles 16a, 16b, 16c are further raised, the yarns are advanced toward the left side of the upper needles 16a, 16b, 16c, and the needle 34 is simultaneously And the lead piece 32 is advanced from the backward end toward the needle side (Fig. 6). On the way forward, the second upper brocade that rides on the yarn splitter 21 is hooked on the second line hook portion 23, and The first upper 43a of the eyelet 3 3 of the lead piece 3 2 is reached by the right stitch i & stitch line stitching of the right needle i & (Fig. 2) Thereafter, the cloth w is fed out of the seam portion while the wire needle 34 and the sheet 32 reach the forward end. Sewing of the upper trim lines 4 3 a, 4 3 b is performed as described above. In the above embodiment, the lead piece 32 is moved toward the front and rear to tension the first upper trimming line 43a, but the amount of the pulling up of the upper trimming line 43a by the yarn splitter 2i is higher than that of the second upper trimming line. 4 讣 pull out the needle and the other is separated and the front side of the yarn is divided into the first stitch 21 wire and then: 43b the second line. However, the first amount of the wire is less than -13-15165, even if the wire piece 32 is fixed, there is no particular obstacle to the formation of the seam, but in order to form a beautiful seam, as shown in the above embodiment, It is preferable to swing the lead piece 32 in the front-rear direction. As described above, the upper trim line 43a is sewn into the first line and the second stitch line stitch formed by the right needle j 6a and the middle needle j 6b, and the upper trim line 4 is sewed into the left needle 1 In the first 筮_ stitch stitch formed by 6c and the middle needle 16b, the upper trim line 43a and the upper trim line 4 are divided into left and right sides of the seam without overlapping. Therefore, in the case where the different color line is used for the upper decorative line 43a and the upper decorative line 43b, the color can be distinguished from the left and right sides of the seam without causing color unhooking. The seams formed by the needle threads 4u, 4ib 4ic carried on the upper needles 16a, 16b, 16c and the yarn separator thread 39 carried on the yarn splitter 38 can be formed by a well-known well-known method. The formation of the seam of the Lingjin lamp itself is not a feature of the present invention, and thus detailed description is omitted. Fig. 14 shows the seam structure of the upper reclining line and the seam of the seam in the above manner. The form of the sewing machine is reversed and moves back to the left (2) to the right direction of the machine, and the manufacturing is formed by the sewing machine of the above embodiment. The irony of the shape of the left and right symmetry is the sewing machine of the left (four) machine. This day (4) can be used for the sewing machine of the heart. Therefore, in the sewing machine of the left sewing machine, the sewing machine of the heart-shaped sewing machine is reversed, and the sewing thread of the first--------------------------------- The second line of stitch stitches is formed by the right stitch from the middle stitch.一丁之在 -14- 201215729 [Simple description of the drawings] Fig. 1 is a perspective view of the main part of the sewing machine of the present invention.
