Needle Thread and Bobbin Thread

I was smoothly sewing until the bobbin thread was tangled. I pulled out the bobbin case and removed the tangled thread from within. When I am trying to start sewing again, I cannot be able to draw the thread from the bobbin.

What is happening when I sew and 3 threads come out of the bobbin? Or when it just freezes up and I can't get the needle to go up or down?

basically the problem comes from incorrect thread tensions
the main thread responsible is the needle thread as the tension is far too loose
tighten up that tension and it makes the needle on the up stroke pull the thread around the bobbin carrier and collects the bobbin thread and pulls it up to the material
with the needle thread too loose the needle thread is wrapped around the bobbin carrier again giving you the 3 threads ( 2 needle threads and 1 bobbin thread and the tangle jams the bobbin movement

The machine is locked up. I've tried checking for thread behind the bobbin case, but cannot get the bobbin case to move.

Check your owner's manual troubleshooting section.

Assuming the machine is jammed with thread:

Try removing all the thread, remove the needle, the presser foot and the needleplate (if it is removable). If there is a thread tangle in the bobbin area, try to snip the thread loops and gently pull with tweezers or needlenose pliers. The best thing would be to get the bobbin case out of the machine. Once the bobbin case is out, the thread should be pretty easy to remove.

The motor locked up because the thread is tangled.
Remove the tangled thread before continuing the operation.
Clean the bobbin case to remove the tangled thread.
After cleaning the bobbin case, insert the bobbin case properly.
If the needle is bent or broken, replace the needle.
Then, thread the upper thread properly, and continue the operation.

Bobbin thread tangles

I am sewing scout badges on a uniform and when I sew there is a bunch of needle thread bunched up on the bottom (the top looks fine). And the needle thread gets all caught up around the bobbin.

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

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.

When you forget to lift the presser foot before threading the machine, the tension control does not open to capture the thread. Then when you begin to sew, the top thread has no tension, and the bobbin thread, which does have tension, pulls the top thread to the bottom in messy loops.

I have a brother pe 770 and the bobbin will not catch the thread. The thread will wrapped and tangled up around the bobbin case and bobbin, but will not catch the bobbin at all. I chcked the needle, it is...

You need to sew the first stitch slowly. Lower the needle by hand and take up carefully. Pull the needle thread up and the bobbin thread should be caught in the formed loop and come with it. Pull them both to the back of the machine and sew.

I have an older machine - Riccar 3600 -- and the spool thread keeps breaking while sewing. What can I do?

Here are some things to try.

If it's Your upper thread breaking:

* Rethread your machine
An incorrectly threaded machine can cause thread to break.

* Decrease the tension on your machine
The tension may be too tight for your thread.

* Reposition the spool of thread on the spindle
You know that little nick in the edge of a spool that’s used to hold the loose end of the thread? Your thread may be catching on this nick as you sew. Place your spool so that this nick rests against the bottom of the spindle.

* Reinsert your needle
Make sure it goes all the way into the holder and that it’s positioned correctly, usually with the flat side away from the bobbin, but consult your machine’s manual to be sure.

* Change your needle
Your needle may be bent or dull. The eye of your needle may have a nick in it that’s cutting the thread as you sew. Or your needle may be too small for the thread you’re using, in which case, change to a larger needle. And make sure your needle is appropriate for the weight and type of your fabric.

* Change your thread
Your thread may be weak. Or your thread may be fuzzy and irregular, causing it to catch in the eye of your needle as you sew. Cheap thread tends to be weak and fuzzy, so make sure to
use a quality, brand name thread. And if you’ve been sewing with an older cotton thread, which can dry out and become brittle with age, try a newer thread.

* Check your presser foot for damage to the needle hole
A burr in your presser foot’s needle hole may be cutting your thread. Gently smooth any rough spot you find with an emery cloth.

* There may be a burr in one of your thread guides, in which case, you may need to have your
machine professionally serviced to have the part replaced.

If it's Your lower thread breaking:

* Reinsert your bobbin
Your bobbin may not be seated properly in its case.

* Rethread your bobbin
Your bobbin may be threaded incorrectly or the thread may be tangled.

* Remove some of the thread from your bobbin
If your bobbin is very full (if it’s hard to insert into the case, it’s too full), this may be keeping your bobbin from turning smoothly.

* Rewind your bobbin thread
If your bobbin thread is wound unevenly, this may be keeping your bobbin from turning

* Try a new bobbin
There could be a nick along the edge of your bobbin spool that’s catching your thread as you sew.

* Clean the lint from your bobbin case
Lint in your bobbin case could be keeping your bobbin from working properly.

* Check the needle hole in your throat plate for rough spots
A burr in the needle hole of your throat plate, usually caused by the needle hitting the throat plate, could be cutting your thread. Gently smooth any rough spot you find with an emery cloth.

I hope one of these solutions work for you.

Jammed thread.

To address my needle thread tangling (horribly) in the bobbin compartment, I rethreaded the bobbin. I cleaned the bobbin and the feeder feet, I changed the bobbin and the thread. I changed the tension on the needle thread and the bobbin thread. NO FIX! Then, I changed the needle - the problem was fixed instantly. I sewed awhile and then put the original needle back in. No problem. I think perhaps that the problem is being caused by the needle getting out of alignment somehow during sewing. If you are having the same issue, try it. It can't hurt!

Thread breaking.

Rethread the machine following these directions:
all machines thread the same. TTN tension, take up, needle.
Beginning with the spool, guide the thread through the thread guides to the tension assembly. Pull the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.) If it passes this test, continue up through the take up lever,then down through the thread guides to the needle. Make sure your needle is fully inserted and turned the correct way.( If you load your bobbin case from the left side,the needle rule is normally FLAT to the RIGHT is RIGHT. There are some exceptions. If you have a newer style drop in bobbin or your bobbin case loads in the front then the rule is FLAT to the BACK.
Remove the bobbin case and bobbin. Pull on the bobbin thread to make sure it doesn't pull too hard. It should have some tension on it but not a lot. Insert the bobbin and bobbin case into the hook assembly and pull on the bobbin thread again.The tension should still be about the same. If it is tight, you need to look at the bottom of the pin that the bobbin case sits on and see if there are any threads looped around it. If there are , you need to remove them.
Hold the top thread , turn the hand wheel and see if the thread is catching someplace around the hook assembly. If it pulls the thread up easily, put some fabric in it and see how it works.
Make sure the thread is through the take up lever.
