チェーンステッチ縫い目等の二重環縫い目の形成をなす二重環ミシンは、図３ に示すように針糸５を供給する縫い針Ｎと、針板１の下方に位置し二重環縫い糸 ３の供給をなす二重環ルーパー４等を備えて構成されている。 そして二重環ルーパー４は、矢符に示すよう進退駆動をなし、縫い針Ｎの保持 する針糸５と二重環縫い糸３とを交差させることで二重環縫い目を形成するよう になっている。 Figure 3 shows a double chain sewing machine that forms double chain stitches such as chain stitch seams. As shown in the figure, a sewing needle N that supplies needle thread 5 and a double chain stitch thread located below the throat plate 3, a double ring looper 4, etc., for supplying water. The double ring looper 4 moves forward and backward as shown by the arrow, and holds the sewing needle N. A double chain stitch is formed by crossing the needle thread 5 and the double chain stitch thread 3. It has become.
【０００３】 なお２は、針板１に形成された縫い針Ｎの針落ち穴である。 ところで二重環ミシンは、縫製開始時において、縫い目を形成することなくミ シンを駆動させる捨て縫い駆動を行う必要がある。 次に図４ないし図６により、二重環縫い目の形成状態および捨て縫いの説明を する。0003 Note that 2 is a needle drop hole for the sewing needle N formed in the throat plate 1. By the way, a double ring sewing machine can sew without forming a seam at the beginning of sewing. It is necessary to perform a waste stitch drive to drive the thread. Next, with reference to Figures 4 to 6, we will explain the formation state of the double chainstitch and the waste stitch. do.
【０００４】 図４は、縫い針Ｎが上昇しこの縫い針Ｎの上昇により形成された針糸５の糸輪 ５ａ内に二重環ルーパー４が進出した状態を示す図である。 これにより二重環ルーパー４は、針糸５を捕捉するとともに二重環縫い糸３を 移動させ、針糸５との間に縫い針Ｎが挿入可能な空隙部Ｓを形成する。 この図４の状態より二重環ルーパー４は後退し、その間に縫い針Ｎは図５に示 すように空隙Ｓ内に下降し、これら両糸５、３が交差し二重環縫い目Ａが形成さ れる。0004 FIG. 4 shows the thread loop of the needle thread 5 formed by the rising of the sewing needle N. FIG. 5 is a diagram showing a state in which the double ring looper 4 has advanced into the interior of the double ring looper 5a. As a result, the double chain looper 4 captures the needle thread 5 and the double chain stitch thread 3. A gap S into which the sewing needle N can be inserted is formed between the needle thread 5 and the needle thread 5. The double loop looper 4 moves backward from the state shown in FIG. 4, and the sewing needle N moves back as shown in FIG. The two threads 5 and 3 intersect to form a double chainstitch A. It will be done.
【０００５】 以上のような縫製作用をなす二重環縫いミシンの二重環縫い糸３は、縫製開始 時においては図６に示すような状態となっている。 縫製開始時の被縫製物に縫い目Ａが形成されていない際の二重環縫い糸３は、 上述の空隙Ｓ（図４参照）を形成することなく、その先端は図に示すように垂下 した状態となっている。[0005] The double chainstitch thread 3 of the double chainstitch sewing machine used for sewing as described above is used at the start of sewing. At times, the state is as shown in FIG. When the stitch A is not formed on the workpiece at the start of sewing, the double chain stitch thread 3 is as follows: Without forming the above-mentioned gap S (see Figure 4), its tip hangs down as shown in the figure. The situation is as follows.
【０００６】 こうした状態でミシンを駆動させると、複数回の二重環ルーパー４の進退動に よりやがて二重環縫い糸３が針糸５と接触することで係合し、縫い目が形成され る。 この縫い目が形成されるまでの間のミシン駆動を当業者では捨て縫い駆動と称 している。[0006] If you run the sewing machine in this condition, the double ring looper 4 will move forward and backward multiple times. Eventually, the double chain stitch thread 3 contacts and engages with the needle thread 5, and a stitch is formed. Ru. Those skilled in the art refer to the sewing machine drive until this stitch is formed as a discarded stitch drive. are doing.
【０００７】 しかしながらこうした捨て縫い駆動を行うにあっては、被縫製物での縫い目形 成開始点を定められないため、縫製品質を安定したものとすることが出来ない、 また縫製の開始までに時間を要し縫製能率を低下させる等の不都合を生じた。 そしてさらに、捨て縫い駆動時に二重環縫い糸３が縫い針Ｎ、針糸５等に複雑 にからみ合って、糸切れを起こしてしまうという不都合を生じた。[0007] However, when performing this kind of waste stitch drive, it is necessary to Since the starting point cannot be determined, the quality of the sewing product cannot be stabilized. In addition, it takes time to start sewing, resulting in a reduction in sewing efficiency. Furthermore, when driving the waste stitch, the double chain stitch thread 3 becomes complicated with the sewing needle N, needle thread 5, etc. This resulted in the inconvenience that the threads would get tangled with each other and cause the threads to break.

It is formed from the side end of the plate 1 to the needle drop hole 2, and the side end portion Ba has a slit width. It is formed so that it widens as it goes outward. From threading slit B on the throat plate of the double chainstitch sewing machine formed as described above, Insert the chain stitch thread 3 into the needle drop hole 2, and place the double chain stitch thread 3 on the throat plate as shown in Figure 2. hold it.
【００１２】 この保持の際、側端部分Ｂａに沿って二重環縫い糸３を挿入するようにして行 えば良く、特別な道具や熟練を必要とせず迅速かつ容易にこの保持作業を行うこ とが出来る。 そしてこの保持された二重環縫い糸３は、被縫製物に縫い目が形成されている 状態と同様の位置（図４参照）となる。0012 When holding this, insert the double chain stitch thread 3 along the side edge part Ba. This holding work can be done quickly and easily without the need for special tools or skill. I can do that. This held double chain stitch thread 3 is used to form a seam on the object to be sewn. The position will be the same as the state (see FIG. 4).
【００１３】 このことにより、二重環縫いミシンの駆動開始とともに適正な二重環縫い目を 形成することが可能となる。 また、二重環縫い糸３が比較的細いあるいは滑り易い等、針板上で保持しにく い材質であった場合には、被縫製物の揺動を防止する周知の布押さえ（不図示） により二重環縫い糸３を針板上に押止するよにしすれば良い。[0013] This allows the double chainstitch to be properly sewn as soon as the double chainstitch machine starts operating. It becomes possible to form. Also, if the double chain stitch thread 3 is relatively thin or slippery, it may be difficult to hold it on the throat plate. If the material is made of a thin material, use a well-known fabric holder (not shown) to prevent the material to be sewn from swinging. The double chainstitch thread 3 may be held down on the throat plate by using this method.
