Worked great until the needle broke and now the bobbin thread bunches up

  • Bobby Whitaker Aug 11, 2011

    There is no maintenance section in the manual that I have. The machine is new and the bobbin area was already checked to assure it was clean and clear of tangles. A new bobbin was already tried, the top thread proceedure was followed according to the manual and no adjustments were made to the bobbin tension since it is preset from the factory and was doing just fine prior to the needle breaking (due to fabric thickness). The needle threading proceedure and new bobbin routine has been tried 3 seperate times and this machine has only been used to make two 18x24 pillow cases. This is why I specifically asked for instructions on checking and setting the timing. I sincerely appreciate your advice but I really need the detailed information that I requested and have paid for. Thank you..B. Whitaker

Hello there,
Have the tension adjusted correctly and the thread and the thread will no longer get tangled. The cause of this problem lies on the type of thread vs the material you are sewing on.
Brother suggests stitching two or three stitches only, then stop and use the reverse feature to make it as strong as possible so that they do not pull out easily while sewing. It's the same concept as using reverse to be your knot. If the stitches are missmatched to the material being used then the first few become too weak to hold and they pull out giving the machine enough thread to tangle. See is using reverse solves or helps your issue.
If it does, then you know we are on the right track and try changing the thread or the material combination.

Here is a link to your model for the manual which includes troubleshootinghttp://welcome.solutions.brother.com/BSC/public/us/us/en/faq/faqh/000000/000000/000004/faqh000004_000.html?reg=us&c=us?=en?=hf_ls2125eus&Cat=52

Hope this was helpful to you. Goodluck Elect_Comp

Hello

Clean out the bobbin area if there are any thread tangles there.

If the bobbin does not fit snugly into the bobbin case, then get new bobbins. You need class A or 15 and they do not cost very much. Make sure they are plastic and not metal.

Refer to the maintenance section of the manual - see the configuration of the bobbin case and shuttle race? The bobbin case as an extending arm and the race a notch. When inserting the bobbin case into the shuttle, turn the handwheel so the needle is at it's highest position. Then lift the lever on the back of the bobbin case and insert the cast into the shuttle, arm pointing straight up toward the bed of the sewing machine.

Now thread the machine with the presser foot up - always - and see if the tangling stops.


There should be a tension setting for your bobbin thread, as well as your top thread. It sounds to me like your bobbin tension setting is not in sync with your top thread.

most common solution to this is to remove the top thread completely from machine and re thread it with the presser foot UP not down. This will allow the top thread to engage properly in the top tension disc

I was sewing with my Brother and it got stuck- whenever I tried to sew, a whole bunch of bobbin thread made a mess underneath the material and pulled until the bobbin thread broke.

Make sure you have cleaned out all the thread pieces in the bobbin area and it is clean.

Install a brand new needle.

Remove the top thread from the machine.
ALWAYS RAISE the presser foot and rethread from the beginning.
Set the top tension to the midway point and test your machine. Adjust the top tension until both threads meet in the middle of the fabric.

Thread started bunching on underside of project & tangling around bobbin. Now the needle won't pick up bobbin thread, even after changing needle 2x and re-threading upper thread. What's wrong?

Hmmm, could be several things.
Try a brand new needle. Try a different brand of thread.
Remove the top thread from the machine. RAISE the presser foot and rethread from the beginning. Verify the thread path is correct.

If it still will not pick up the bobbin thread, the machine could be out of time.

The bobbin thread is bunching up

hi Lois.
this is all i could find out.
Check Your Tension Settings. Looping underneath the fabric usually occurs when there is not enough tension in the needle thread to pull the bobbin thread. Sometimes thread bunching can be caused by something as simple as the tension dial being inadvertently turn.
or try this link.

Try these suggestions

1. Change the needle--use a needle that's for the fabric being sewed

2. Rethread the machine--top --make sure to use every thread guide

3. try a different bobbin--make sure bobbin is inserted correctly into the bobbin case, & make sure the bobbin is turned the correct way in the bobbin case

4. make sure the thread has not come off the thread take up lever

5. Clean under the needle plate & in the bobbin area for lint or threads

6. Also could be a timing problem, and the machine would need to be checked.

Sewing a bunch of thread from the bottom, this stops the machine from actually sewing

Yes, it does. There are a couple of reasons the bobbin thread could be bunching up on the underside of the fabric. It could simply be that the machine needs cleaning. Take the bobbin assembly out, brush all the old lint out as best you can, reoil the machine once it's all clean, and make sure there aren't any little bits of thread caught in the bobbin assembly. Rethread the machine (carefully) and change the needle. This solves the problem usually--especially if the machine was sewing along fine and the problem develops suddenly. '
The other thing to check is your tension. It could be that the top tension is too loose. But different color thread in the top and in the bobbin, stitch a few inches (be sure to held the top and bobbin thread ends behind your needle as you start to stitch) and check. WIth the pressure foot down, adjust the tension, and stitch again. Keep stitching, checking, and adjusting until you see little if any bobbin thread on the top or top thread on the bobbin.
Another thing to reminder: use the appropriate thread and needle for the fabric you're sewing.
Let me know if this works, ok?

Singer 7422 bobbin thread bunching up

I assume you checked to see there are no needle bits in the bobbin case holder.
Without looking at the machine it is difficult to diagnose the problem. It could be any one or a combination of problems, timing, needle bar height, damage to the hook and base etc.
I strongly suggest you have it looked at by a sewing machine tech.
