The Joys of Industrial Machines – Part 2

Filed under: Machines — Gigi @ 9:51 am

This little gem of a machine is a Merrow 2DNR-1. It makes a perle edge like you would see on ready-made napkins, tablecloths and garments. At first glance, the perle edge looks like a rolled hem but it’s actually just a 2-thread overedge stitch. Does DNR mean “does not roll”? Who knows! The stitch length on this machine is controlled by a cam. When I acquired this machine a few years ago, I had a 32 spi (stitch per inch) feeder installed. I wanted to be able to achieve a nice solid edge without having to use texturized thread. The thread you see here in my samples is 40 wt. polyester machine embroidery thread. It’s much easier to get a perfect match this way.

Threading this machine does take a little practice. Some of the guides are internal and can only be threaded with a wire threader. Aside from sliding out the needle plate, the machine does not open up in any way for threading. It was a challenge at first but after a few tries I got the hang of it.

This machine uses a short, curved needle – system 60M/151×1.

The thread nestles in a groove on the curved side of the needle before being threaded into the eye. Sorry, about the red lint! That’s obviously leftover from some Slinky samples I was working on recently. The thread chain is also handy for those rare occasions when you might need thread belt or button loops.

This little machine just purrs along while effortlessly making a beautiful perle edge on either woven or knit fabrics.

If I use a knit and stretch the fabric,

I end up with a gorgeous lettuce edge.

I must confess that I recently toyed with the idea of selling this machine to make way for my 2nd coverstitch. While I love it, I don’t really use it all that often. Diva Mary Beth talked me out of selling it and she’s right. This model is hard to come by and, having sold my last domestic serger, I no longer have another machine that will do a narrow edge. Instead, I cut about 18″ off the left side of the table so it doesn’t take up quite as much space.


  1. Gigi, thanks for all the information shared about industrial machines.

  2. My mother always says – you need the right tool for the job and if it doesn it well enough it doesn’t matter if that’s all it does.

  4. I have this model too and while threading is challenging, it’s better than all those twists and turns on my Elna D5pro serger. It’s cool how the presser foot swings out of the way but I still had to loosen the front plate to get the thread through the guide.

  6. Hi Gigi,
    My mother worked with Merrow machines years ago and always talked about how great they were. I knew it was a type of industrial serger now I can finally see what she was talking about. Thanks. :O)
