Piping Binder or Dayu 109

by Chrissie

How does this Piping Binder work? How it’s attached, and how to fit the fabric in is explained in here.

Here’s what you’ll need

You’ll need a base plate (I’ve used the original one from Janome).  Two washers and obviously a piping binder, in this case the “Dayu 109”. And of course one screw to attach the base plate on your Coverstitch-Machine and two screws to attach the binder on the plate. You want to lay the washers on your base plate before attaching the piping binder with two screws.

If you do not know how to attach a common tape binder you can check out my video on youtube (it’s for the orignal binder from Janome Coverpro, but it works basically the same way for other models too.

This is what it looks like when attached.

Do not get confused, I’m using the Elna Easycover which is the same model as the Janome Coverpro 2000 CPX.

Piping Binder, really?

The name “piping binder” confused me a bit, because there isn’t acually a “real” piping you’re going to sew.  In my opinion the piping binder should be called “false piping”-binder.

No cord attached to the fabric though. There are just two layers of fabric one will sew on in one step.  So that’s all there is to the piping binder.


You’ll find the measurements for the fabric-stripes written on the piping binder itself. You’ll need two stripes.

large one : 1 3/
narrow one : 1/2

It is advisable to use a lighter fabric for the smaller stripe in order to make sure, that both layers are going to run smoothly through the piping binder while sewing.


Sometimes it’s necessary to cut the stripe a bit wider or smaller, depending on the fabric you’re choosing.

I like to cut the stripes with my rotary cutter. Obviously you’ll need a third fabric too which you want to bind. This can be a T-Shirt for the neckline for example.

Ready for mounting the fabric into the piping binder?

Mount the wider stripe

It can be pretty annoying sometimes to fiddle the fabric into the binder, until you get used to it.

A pair of tweezers can help to push the fabric into the piping binder.

When the wide stripe is fiddled in you want to make sure, that the upper edge is folded over (as showing in the picture below). The Dayu 109 is a binder type A. This means there is only one edge folded over. There are also binders with specification “type B”. Those binders are folded on the top and the bottom.

 Mount the narrow stripe

Let’s proceed! For the narrow stripe I took a long needle like it’s been used for sewing dolls. This worked out pretty well for me. The needle helps you to push the fabric into the binder.

What is the difficulty with the narrow stripe?

In my opinion it’s a bit more complicated to fiddle in the narrow stripe, because there is a huge gap. So make sure, the fabric stays in its channel.

With a bit of patience though it’ll work out for sure. Promised!
Pull the fabric out as long as you need it for fitting it under your sewing foot.


Let’s sew!

 Sewing with three Needles

This is what the result looks like with three. I realized later on, it’s not so pretty, it would be nicer sewed with two needles.


Sewing with two needles (left and middle)

If you realize your fabric is stuck in the binder, then it’s probably because your narrow stripe is cut too wide. Take a look at the very narrow opening of the binder. If your stripe is too wide this can cause a “fabric-jam”.


Needles left and middle: 3
Looper: 1
Differential: 1.5
Sewing Foot pressure 0.5″
Stitch-Lenght 3.5

You may realize that the left needle is a bit too tight. This is the way how to find the perfect adjustments for your machine. Sew, analyze the stitch-image, adjust the values if necessary and sew on.

Don’t forget to write all down, so you do not have to search every time for the perfect adjustments.

On the back there isn’t enough thread-tension.

Based on the knowledge above I’d do the following adjustments for next time:

Needle left: 2
Needle middle: 3
Looper: 2
Differential: 1.5
Sewing Foot Pressure 0.5″
Stitchlenght 3.5


The adjustments for your Coverstitch Machine are based on the needles and the thread you’re working with and of course your Coverstitch-Machine. This can diversify although two persons got the same brand!


Have you already made some experiences with the piping binder?

Thank you for this very informative article. I was confused because there was this dayu 103 which is also a top clean – raw bottom binder. But this gave me an idea that maybe the dayu 109 has this extra attachment. The dayu 103 has provisions for adjustments for the top and the bottom sides of the fabric. Does this dayu 109 have them also?
Thank you,

Hi Peter
There are 2 screws which you can adjust. You just need a steady hand and there is a bit fiddling around, but it works.
