  • Frances, Check to make sure that you don't have a bad needle. If there is a slight burr on the point of the needle, it will cause this. Or if your needle isn't in straight.
  • If you have broken a needle, you may have a groove on the inside of the needle hole in your throat plate. You can take your plate off and buy emery string to run back and forth to smooth that out or you can buy a new plate. (look under your plate and there should be a number engraved on your plate to guide you into purchasing the right plate.
  • Check your bobbin to see if its wound evenly and that there aren't any grooves in the edges of your bobbin (if there is, throw it away).
  • Lean your machine back and run your finger along the outer edge of the shuttle to see if there is a rough edge that might be catching the thread as it revolves around. If there is, buy a piece of fine emery paper at a hardware store and buff it smooth
  • Are you using smooth thread and a big enough needle? If your needle eye is too small for the thread or the needle is too small to punch a big enough hole in the material for the thread to pass through easily, it will sometimes cause skips like this.
  • As a last thought, try a different foot. If your foot doesn't hold the material tight to the feed dogs while you are sewing, the material will 'follow' the needle up and down and cause skips.
  • Good Luck!

SOURCE: Top thread stitches correctly but bottom thread loops.

FYI---- Loops on the bottom-- problem is in the threading..
Loops on the top--- problem is with the bobbin.

I have a brand new Juki MO-50e and the threads are loose on the back of the fabric, how do I fix this?

  1. . re-thread your machine with a rainbow of colors. (important that you remove the existing threads if you are not sure it is threaded properly.) make sure you are lifting the presser foot while rethreading.
  2. Sew a good 6 inches.
  3. Look to see which threads are the offenders and tighten the co-responding tension knobs a little.
  4. Sew another 6 inches. Examine the result. Adjust tension again if needed.
  5. Work this way until you have the stitch balanced.
  6. Finally when your stitches are perfect. clip the threads at the spools in back. And tie on the coordinating colored thread for your fabric.
Get used to this procedure since it is common to have to adjust tensions when you change fabric. Good luck!

How do I know that machine is in working condition ddl-5550

A little more information please. I have this model, and it only does a straight stitch and reverse.
Have you turned it on and tried sewing on it? Is the oil pan dry? Has it been serviced at all, or maintained?
We can't help you without more info.

My wife broke several needles on her Juki DDL 555 machine and I need to know how to adjust the timing as she put a new needle in and the point was damaged

First thing to check is if you've got the right needle system: and that the needle is correctly oriented... the scarf has to be precisely set.
The next things I'd check are the stitch cycle -- hand crank the machine through the normal stitch cycle and see what's hitting. Then fix that. I've got my suspicions this may be a needle bar height adjustment. Don't thread up for this test... misthreading can also cause the needle to hit something and break, so start with the fewest possible variables first.

Bottom thread on Juki DDL-5550 is coming up. Top thread seems to lie flat

Check your upper thread at the spool. I've had industrial machines randomly throw a loop around the spool holder spindle which is hidden under the spool itself.

Also check your threading guide to be absolutely certain you are threading it correctly. Also make sure needle/thread diameter are suitable for each other.

Good luck.

Make sure you are threading the machine correctly. Make sure you are using serger thread that isn't old. Make sure you are undoing all the threads when it breaks and thread it from the beginning.

Make sure you have the right needles in their respective places. My Juki MO has two different size needles.

Make sure that the needle is inserted all the way up and is facing the correct way. Tighten the upper tension gradually until the stitches look even on top and bottom.
