Instead of reinventing the wheel, I'm looking for advice to use a (basic) sewing machine to sew a line from right to left (or the other way). The feed dog of my sewing machine (and most machines) is made to stitch a line front to back

sewing right to left how to sew a straight line left ⇆ right (instead of front ⇆ back)

I know that I will need to cover the feed dog (using a cover plate), then I will need to slide the fabric manually from right to left with the steadiest speed (for aesthetic: to keep a regular space between the stitches).

If you tried it with a normal sewing machine, I'll be glad to collect your advice! (Does anyone knows what this is called? It's difficult to Google it without knowing the term.)

(That would be useful for many things like drawing a long line following a long tube such as a pant leg)

I don't see how to cover or deactivate the feeding dog so it won't interfere.(@Elmy).

You just need a feed dog cover plate: enter image description here

  • You're just going to end up with uneven stitches and a broken needle. Some home machines do have the ability to drop the feed dogs, but evenly spaced stitching in a straight line is still difficult on them. Better to just make your pant legs the normal way. – Allison C 2 days ago

You need to change your perspective to solve this problem.

Short of breaking your sewing machine, I don't see how to cover or deactivate the feeding dog so it won't interfere.

Usually, you can remove a cover or compartment right under the bobbin case to expose the "sleeve arm" or "free arm".

Then you align your fabric in a way that the seam lies on top of the arm and the opposite end below the arm. You should pin the seam very well for this.

Simply start sewing the normal way. The left side of the tube can move forward freely, but the fabric will bunch up on the right side (In a certain way, the fabric will actually move left to right, but you still sew from the back to the front). Keep sewing and bunching the fabric up, until you've sewn at least half of the entire length. Then you can repeat the same process from the other side if the bunched up fabric hinders you too much.

As a general advice, ignore the bunched up fabric as much as possible. Just push it out of your way as best as you can. the only important thing is to keep the seam aligned with the feeding dog.

If the tube you're trying to sew is still to long for this method, I'm afraid you'll need to use a professional sewing machine like this one.

  • Thanks! I'm not sure to understand (a video would be handy!). But if I understand well, your technic only works for small tubes. I was wondering how these pant maker sewing machine looks like, thanks for that! (It's easy to get rid of the watch dog, see the update in my question). – JinSnow yesterday

    @JinSnow Sorry, but I can't find a video of someone sewing that way on a non-professional machine. It just isn't done ;-). May I ask why you even want to do this? Isn't sewing the the sleeve or leg with right sides together and then pressing the seam open enough? Like demonstrated in this video at 2:00 minutes – Elmy yesterday
  • I'm just curious to know other creative way to use a sewing machine (the rest ( to sew a long line on a long tube) is just an excuse/challenge). The video doesnt fit: I don't want to make a tube, I want to draw a line on a (very long) tube (already sewed). – JinSnow yesterday
  • @JinSnow I tried to explain what I meant better. Basically you just sew the normal way and keep the fabric that cannot move past the arm out of your way. If the fabric is not too stiff and the tube not too tight, you can sew several meters with this method. – Elmy 23 hours ago

it's actually much easier than I thought (if you don't mind about spacing). But I guess there are some tricks I don't know.

What I did is

  • put the "feed dog cover plate" (it disable the feed dog) so you could saw in any direction)
  • pass the "tube" through the machine
  • just pull back slowly the fabric to sew a straight line

It's pretty easy a low speed (what I find difficult is to keep a low and constant speed, using the "foot speed controller". It would have been easier with a preset speed). Basically the more you pull the fabric, and the slower the needle goes, the bigger are the spaces between stitches.

if you are not sure, run the machine manually (by turning the wheel) for a few stitches. It's slow but still much quicker than sewing by hand, and you can set spacing exactly where you want. It more difficult with the motor on, but not impossible if you manage to have a constant slow speed.

I also tried on the tricky part to saw without the presser foot (I put it up) which worked well.

(I tried nearly 2x1meter a kind of jeans fabric, I did not break the needle without really caring about it)
