The extracted edge is located below the cut edge. The cutting edge in the form of a front slit is drawn out of the tail section 67 of the loop line 12, and then led to the corresponding cutter 22 for cutting, and the edge is extracted _ • The starting end 54 of the knot is from the front end of the collar 53 (d), but do not cut it. The mode of operation will be described below with reference to Figures 9 through 11. In the position shown in Fig. 9, the start of the loop line 12 is held at 4 from (4) (four) 9 to the clip 53' at the device. The starting end extends beyond the clip 53 with a remaining section 68. A seam 69 is now inserted into the seam holder 13 in a manner known per se, where the seam is clamped between the clamping plates 15, 16; and then the round buttonhole seam 70 is sewn. The stitching of the round buttonhole is mainly made by moving the χ-y table 1〇 and the sewing material 69 sandwiched thereon in the y direction and to a limited extent - moving in the X direction with respect to the pinhole attachment 9 7 inches of sewing. The sewing of the round-hole buttonhole seam 70 is carried out in a conventional manner. Of course, the loop line 12 and the needle thread 6 together form a seam 70. Since the (sewn) condition and the cutting of the needle thread 6 are performed in a manner known per se, the description will not be repeated here. At the end of the sewing process, the starting end 54 of the loop line 12 is again at the same position as before the sewing work of the buttonhole seam 70 is started. In addition, the tail section 67 of the loop line 12 extends from the knob line slot 70 to the pinhole attachment 9. At the end of the round buttonhole sewing operation, since the pinhole attachment 9 is again approached to the position of the lower clamping plate 16 with respect to the slit holder 13 as shown in Fig. 9, the xy table ίο is moved in the y direction so that The round-hole buttonhole slit 7 is reached to the buttonhole cutting device 18. Here, the buttonhole 71 is formed by actuating the anvil 20 from the top to the bottom and engaging the cutter 19 by 13 . In one position of the x-y table 1 ,, the pinhole attachment 9_ is located between the greening device 24 and the clip 53 as shown in Figs. The wire deflector 43 is located above the starting end 54 of the loop line 12. The linear actuator 27 is now operated, whereby the threading device 24 is moved with its take-up and 5 cut-off regions 26 in a counterclockwise direction in the direction toward the clamp 53 and the corresponding cutter 22 - Fig. 2 . At the same time, the pivoting bow 44 that has moved upward to its stop position shown in Fig. 5 is released, thereby moving downward to the working position shown in Fig. 6, which means that the line deflector 43 is also pivoted downward. And pressing down the starting end 54 of the loop line 12 below the deflector, thereby grasping the starting end 54 by withdrawing the edge 66 instead of the v-shaped cutting edge 65 as the 1" picking device 24 moves further forward. . The tail section 67 of the loop line 12 that is closer to the threading device 24 has been grasped by the cutting edge 65 of the take-up and cut-off region 26 in the form of a ¥-shaped slit and is dragged in a direction toward the corresponding cutter 22. Before the drawing and cutting area 26 of the threading device 24 reaches the corresponding tool 22, the control button 62 of the lever 61 touches the operating pin 58 of the flexible clamping portion 56 to open the clamp 53. As the threading device 24 continues to move in the direction of the corresponding tool (10), the withdrawal edge 66 can withdraw the starting end of the loop 12 from the clip 53. On the other hand, the tail section 67 of the loop line 12 dragged by the v-cut edge & is inserted into the clip 53. At the end of the pivoting movement of the extraction device 24 towards the corresponding tool _ 2 frame, the starting end 54 of the entanglement line 12 has been withdrawn from the wire clamp 53. Hai began to know 54 will fall. The tail section 67 of the loop line 12 is severed on the corresponding cutter 22. By appropriately designing the control button 62, the operation pin 58 is released again at this position, thereby closing the line loss 53. The butterfly spring illusion helps move the control 61 back to its original position. The end of the loop line ^ ^ Yang online husband ^ 14 1333989. The linear actuator 27 is then actuated to retract the piston rod 29 into the cylinder 28 such that the threading device 24 is again pivoted back to its position shown in FIG. The wire deflecting device 38 is again pivoted upwardly to its stop position shown in Fig. 5, i.e., the frame bowing portion 44 is forcibly moved upward by the operating section 49 of the operating lever 47, and the carrying wire deflector 43 is moved upward. . When the xy table 1 is reversely moved to the position shown in FIG. 9 where the pinhole attachment 9 is located below the lower clamping plate 16, the looping line 12 on the wire deflector 43 is abutted at the end of the wire cutting process. The tail section 67 is pulled downward from there to move to below the line deflector 43 and to the position shown in Fig. 9. 10 Then, at the end of the buttonhole sewing operation, the tail section 67 of the looping line 12 becomes the starting end 54 of the looping line 12 for the sewing operation of the next round buttonhole seam 70, as shown in Fig. 12, After the cutting operation, the starting end 54 and the ending section 67 of the looping wire ^ are located on the sewing material 69. The starting end 长 is longer than the tail π by more than 15 segments 68. According to the prior art, the remaining section is always cut off, thereby damaging the sewing machine. The starting end 54 and the trailing section 67 are pulled down through the buttonhole slit η, where they are stitched and then manually cut.
