It is easy to reduce the speed of sewing, and it is easy to achieve the speed of the sewing speed. In addition, the seam = the upper wall portion of the front end portion of the arm portion is generally formed with a needle holder insertion hole, and the second frame is not used at the time of normal sewing. For example, the cover 1 = can be used in advance to roughly sew the arm portion. Sealing, therefore, it can prevent flatness; oil leakage during sewing work, and prevent dust from intruding into the arm of the sewing machine.

This activity needle line ^ 4 member 8 right side The front portion of the slitting arm portion i is provided with a fixed needle thread passage 13 that is integrally attached to the needle thread, and three variable needle threads, and the needle line oil supply device 12 is connected from the four thread tensions. (3 pairs of needle thread 9 and 1 line hook line 1 () can be given a frictional resistance, individually adjusted: tension) 11 of the 4 lines shipped out and guided by the three needles 9 to gather gas, over ' And in the material 9 coating the phase oil, the three variable needle thread passing through the three needle thread 9 after the fixed needle thread passage 13 can be connected to the line passage ammunition table 14 (fixed connection) The fixed needle thread is fixed through the long hole 15 and the screw 16 respectively, and can be changed along the upper and lower sides (the arrow Ul-dl direction). In the front (left) end and the long side direction of the movable needle threading member 8, three needle thread passages 13 and a variable needle thread passage 17 which are arranged at the same height and three lead wires are respectively formed. The supply is caused to cause the middle door to be placed, and the needle thread formed on the left and right sides of the arm portion 1 is fixed to the left end of the arm portion 1 : the needle thread formed on the line guide 18 is directed toward the cut-down guide; and the needle thread feed line needle thread is Active needle thread feeding member between L8B = set: open three brothers 3 needle threading hole 8C pin-and-body, the third needle threading hole 8 is sent one, the extended needle thread part = two needle thread In the state of a substantially symmetrical V-shape, it is sent and guided. Left and right 1289163 In this state, the needle holder 3 and the needle 5 are driven up and down reciprocatingly, and the movable needle thread feeding member 8 is synchronized with the needle thread feeding shaft 6 Center, = lower (arrow direction ud direction) reciprocating rocking motion, while maintaining the thread tension and sewing state generated by the thread tension 11 while properly controlling the needle thread 9 without applying looseness or excessive tension to the three needle threads 9. The amount of delivery, the thickness of the unconstrained fabric can be set On the other hand, in the case of sewing a fabric made of a material such as a microfiber cloth which is very flexible in repairing and contracting, the needle thread 9 supplied by the fixed needle thread 2 13 and the variable needle passage Π is used. The sequence is formed by the needle thread feed member 8 (four) 2 needle thread feed hole 8B, the third needle thread feed hole c, and the first needle thread feed hole 8A, through the needle thread hole 18 & of the needle thread feed guide 18, and is Therefore, the entire length of the portion of the needle thread 9 attributed to the movable thread feeding member 8 is long, and the portion of the long needle thread 9 is slid downward in the substantially V shape by the 13 thread feeding hole 8G. The wire tension benefit 11 is imparted to the needle 9 to send the frictional resistance so that the thread tension does not become an appropriate value of the sewing unevenness and is interlocked with the downward movement of the needle threading member 8 and the needle 3 and the needle 5, and When the ascending position shown in Fig. 5 is oscillated to the lowering position shown in Fig. 6, (-) from the variable needle thread path I?, the distance L of the first needle threading hole 8A at the tip end of the movable needle threading member 8 is increased. The larger the bottom, (2) from the 2nd needle threading hole 8B toward the 3rd The posture of the needle thread portion 9a of the thread feed hole 8C is gradually downward, and the needle thread feeding force f which is given to the wire tensioner I is given is stronger as it is lower, and (3) the moving thread member 8 is shaken to the figure. When the lowering position of the 6th position is the upper position, the 3rd skewer, the 3rd line of the 3rd thread, and the 3rd thread feeding hole 3C are 11 1289163 = 'the line of the thread part 9b is the threaded seat 19 The flap portion 19a blocks, and since then, the movable needle thread feeding member 8 is rocked to the lowered position of Fig. 6, and with this, the blocked needle thread portion 9b is changed into an upwardly bent posture to resist the generation of the thread tensioner 11. The needle thread delivery force that sends out the frictional resistance is further enhanced, so the amount of needle thread delivery is larger as it goes downward.曰Because the amount of the needle thread 9 produced by the movable thread feeding member 8 is larger as it goes downward, even if a fabric made of a material that is very soft and rich in shrinkage is used as a sewing object, such as a microfiber cloth, It can still make the needle thread part of the needle field 5 through the fabric to the bottom dead center, and the needle thread part of the 胄5 from the bottom dead point through the rise of the fabric to the upper dead point is not extremely tight, and has a slight degree of slack, so it can be clothed The yarn loop wound around the claws of the needle plate during feeding is smoothly separated from f, and the excessive tightening can be eliminated, and the sewing of the cloth is prevented from being reduced by the arched ridge and the like. This excessive tightening is caused by the fact that the needle thread pushes down the cloth portion passing through when the needle 5 penetrates the cloth from above, or because the needle 5 is separated from the cloth when the needle 5 is separated from the cloth. The line hook line on which the shame is placed is between the first needle thread feed hole I at the front end of the active needle thread feed member 8 and the needle thread hole of the needle thread feed guide 18: the needle thread socket at the midway position 1...one line 2 is shown in Figure 4 with the right side (the line hook enters the earliest side of the needle loop). The most = the middle and the left side are sequentially lowered. The time of the 3 needle loops below the door is "1: hook entry. The longer the yarn loop formed on the left side of the fabric, mn, and 疋, the slower the three needle thread 9 when the needle thread feeding member 8 reaches the lowering and the larger diameter 、3, and the sewing is as follows. A soft tissue cloth such as a microfiber cloth 12 1289163, which can prevent the sewing portion from being arched, and in the above embodiment, although it has been reported, the product is reduced. However, as shown in Fig. 7 and In the case of the 8th line bearing 19, the 3-pin chain stitching machine of the bearing 19 still has no needle threading effect, so that the larger the movable thread feeding member 8 is, the more the sewing is prevented. When the microfiber cloth moves, the quality of the needle thread is reduced, and the sewing is performed when the fabric is soft.
