長尺が可Ｉｌｌとなる。In conventional up-and-down sewing machines, the bobbin thread is wound around the bobbin and placed inside the bobbin case, which limits the size of the bobbin case, making it impossible to use long bobbin threads. Therefore, with industrial sewing machines and many types of embroidery machines, it was time consuming to replace the base. Also, since an automatic stop device for bobbin thread breakage is not installed, if the bobbin thread breaks during embroidery, it will result in a defective product, so I had to replace the bobbin thread early, which resulted in a lot of wasted thread and time. An example will be explained using I7 based on the diagram. Figure 1 is a rotating sectional view of the sewing machine, with drive shaft 1, hook 2, middle hook 3,
is a well-known method, but make a hole in each of them, insert the bobbin thread from the bobbin winder 5 into the inner hook in the order of 1.2.3, and adjust the thread adjustment/f screw of the bobbin case 4. By inserting the bobbin thread into the thread, the length of the bobbin thread can be increased.
また少量生産のときは従来通りボビン４二下糸を巻き使
用する事も出来る。In addition, when producing in small quantities, it is also possible to wind the bobbin 4 with two bobbin threads as before.
尚この装置は垂直釜、水平釜、何れもとも使用する事が
出来る。This device can be used in both vertical and horizontal pots.

構造が簡１こなり、系取付（３作業も容易となる。In addition, for embroidery sewing machines and mass production sewing machines, as shown in Figures 1 and 2, you only need to attach a thread waste device to the inner hook without attaching a bobbin mounting shaft or bobbin case.
The structure is simple and system installation (3 operations) is easy.
また下糸のねじれ防止に１よ、図のよう番こ中釜より、
駆動軸の外まで案内／ｆイブを出し、駆動軸１こ糸が接
しないようにするとよし１゜Also, to prevent the bobbin thread from twisting, use the inner hook as shown in the figure.
It is a good idea to extend the guide/fiber to the outside of the drive shaft so that the threads of the drive shaft do not come in contact with each other.
