How to prevent the upper thread of my sewing machine gets tangled around the bobbin.?

Question

Every time I sew, the top thread of my machine gets tangled around the bobbin.

I have tried putting in the bobbin again and making sure its in properly, I made sure the needle was in properly, and I threaded it properly. I dont know what else to do :(

Answer 1

Could be a lot of things, but sure sounds like what used to happen to me until I figured it out.

fourfeetsix answered the way I would have.
That is, make SURE both tails of the thread are pulled out of the way of the needle at all times, but especially when first beginning to stitch! (or one or both will get pulled down into the bobbin, making a mess)


Good luck!

Try the following:
1. Oil the sewing machine: Old oil will turn to varnish, and must be removed with alcohol before adding new oil. Otherwise, machine parts stick and will not run smoothly. (Also,for this reason, too little oil is better than too much.)This is what most repair people will do when you bring your machine in for service

2. Disassemble your bobbin case which is realy quite easy, clean thoroughly with a brush and air, paying particular attention to any rust that may have formed, and any thread that may have weazeled it's way into small but very incremental areas of your case.

3. Make sure your needle is not in backwards.The rounded side should be on the outside

4. If threading is correct and your tension is properly adjusted (refer to your manual) and you have a NEW needle (change every 4 hours, you will be amazed at the difference! ), then check the hook for scratches. If you have ever hit the hook with a needle, it will be scarred and will catch the thread every time the upper thread passes around the bobbin case. the hook is the sharp point on the shuttle that holds the bobbin case. If it is scratched, polish it smooth with VERY fine sand paper, or a green stick (flexible abrasive available at most auto supply shops.) The stitch cover plate may be scratched too; same remedy works here, although to get into the tiny feedog slots, you need abrasive dental floss.

5. Make sure that your thread arm that rises and falls, constantly having tension running through it and that it is in fact staying in place.

6. Alternate between the metal and plastic bobbins - sometimes the plastic bobbins tend to chip

If these basic home techniques don't work, then you may have a "needle - bobbin" syncronization problem.


Good luck fixing it yourself! If you find that you need to take it to an expert, don't worry! it's not wasted money. You will be able to sew more things and save! Have them show you what they did, so you can fix it yourself next time.

Answer 3

Have you dusted the bobbin case? (use a soft brush like a new, clean blush brush, sometimes they come with the machine). Is your tension set correctly, according to the manual? Are you sure the thread is feeding from the correct side? Is the needle properly inserted and threaded?

Answer 4

I like everyone elses answers, but I can tell you WHY its happening. Not really how to fix it tho. If your top thread is acting up, the tension on the BOTTOM is wrong. If your bobbin thread is acting, the tension on the TOP is wrong. Check your owners manuel to see how to adjust the tension.

Answer 5

Pull both threads back behind needle, away from you, before starting to stitch.
