Rotary Take-up - What it is and How it Works - Industrial Sewing Machine
Тәжірибелік нұсқаулар және стиль
I have this Juki DDW-9A industrial plain sewing machine on the bench for service and it has an unusual rotary take-up mechanism.
Rotary take-ups were designed so that the take-up mechanism would cause less vibration, therefore less wear and more speed was achievable.
A take-up is a very important part of any sewing machine and provides exactly the right amount of slack in the system at exactly the right time. This allows enough slack in the top thread so it can make its way around the hook, to then be pulled up to create a tight stitch at just the right time.
I compare the rotary system with the more traditional linear system.

I had no idea a setup like this for a sewing machine even existed! That machine looks very well built.
Simply thinking about the idea without finishing the video, this is beautiful, in a sense that it’s simple, elegant, less vibration, more encapsulated, etc. Not just that, the amount of take up can be easily adjusted after leaving the factory, if needed. Obviously to me, that’s another new dimension of possibilities.
This is interesting. I’m always fascinated by the many different, but equally beautiful ways used by different machines for same or similar problems. There is always room for innovation. Always ample room.
Well, what a wonderful video and mechanism! Beautifully filmed too - I learned all sorts of things. Thank you!! :-)
Thanks for posting this explanatory video. I learned a lot seeing this.
What a wonderful machine!
You might be interested to know that Juki also made domestic machines with this set up. At one point they were even marketed under the White brand.

I have a vintage juki industrial. My favourite, though having problems with the control box, which I tried to repair but without success. I might just replace with a servo motor. Would keep an eye out for a used juki domestic.
I need advice. I have a Singer 700G machine, it had been tossed out curbside, on trash night, when I rescued it. It is missing the throat plate cover and Needle Bar door. I have no luck finding these parts. I believe the "G" on the front of the machine, stands for GERMANY.
I have 2 or 3 examples of the domestic version of this that was available in the USA, the Juki "Rotalix". Interesting machine, and it certainly saves on the parts count. But what I couldn't understand is why it's an oscillating hook and not a rotary! A rotary would have been SO much faster and smoother!
