How to connect thread to 91k5, 91k6

[ddiuni]

The tension control of the circle part was not tight, so I removed it again, fixed it, and then sewed it again, and the sewing worked well.
However, the size of the photo only increases by about 1.4M.
First of all, I adjusted the tension control part of the circled part in the picture I uploaded, and it is sewn. Sewn limbs will be posted in the next post. However, if you look at the picture, the stitch itself is forming a thread on the lower thread. Is the original 91k5 and 6 sewn in the shape of a string at the bottom? The top is very well stitched.

Now I'm wondering if this machine actually has a take-up lever as I know them?

The sewing on the lower thread worked well.
However, it is not flat, and 91k5 and 6 are stitched like this, so can they be sewn?

사진이 매우 흐릿하고 식별하기 어렵습니다. 실 복귀 스프링과 실채기가 보이지 않습니다. 위의 마지막 사진 각도에서 바늘을 아래로 한 다음 바늘을 1/2 위로 올린 상태에서 사진을 찍을 수 있습니까? 사진 크기를 너무 많이 줄이지 마십시오.

I adjusted the tension first, and the sewing works well.
I can't upload only blurry due to photo size limit
I'll re-upload it one by one.

However, if you see the upper thread and the lower thread are sewn on the lower side, a thread is formed and it is sewn. I don't know if it's like this in the first place. I don't know if this is the characteristic of sewing 5 and 6 of 91k.

이제 이 기계에 실제로 내가 알고 있는 테이크업 레버가 있는지 궁금합니다.

I'll post the picture you mentioned.
First, look at the picture of the sewing and see if it is right to sew like this.

I believe what you have there is a what we call a chain stitch machine and the bottom thread looks like this normally. As there is no bobbin you can not get a lock stitch to form as many other machines do. I think you have it as good as you can get it for now.

나는 당신이 가지고 있는 것이 우리가 사슬 재봉기라고 부르는 것이고 밑실은 일반적으로 이런 모양이라고 믿습니다. 보빈이 없기 때문에 다른 많은 기계처럼 잠금 스티치를 형성할 수 없습니다. 나는 당신이 지금 그것을 얻을 수 있을 만큼 잘 가지고 있다고 생각합니다.

So it looks like a chain that is sewn on the underside of the fabric.
The lower thread seems to be sewn in a spiral shape.
I recently bought a 91k5 and 6. So, I got the needle up to number 14....
Needle 9 is out of stock. And in the video uploaded to YouTube, it is explained that the person using the needle uses number 16. If you have thick gloves, you should probably use the number 16 needle. 46*1 needles are no longer produced in this world. Sooner or later, the needle will disappear, and this sewing machine will remain as an antique.
