Bobbin thread breaks

My bobbin thread breaks after sewing about 5 inches. I've checked to make sure I've threaded the machine correctly and the bobbin is installed properly. The sewing machine tension is correct. What can be the problem?

Make sure your bobbin thread is turning clockwise as it sits in the bobbin case. There is a screw on the outside of the bobbin case you can turn with your thumb slightly to adjust tension. If you dangle the case from the thread and give it a light ****, it should move down slightly when doing so-an indicator of good bobbin tension.

Things to check for thread breakage (top or bottom)

1. Good thread in the machine - not hand thread, cheap thread, quilting thread.
2. A burr on the hook - a small nick on the hook can grab and tear threads, however this usually causes the top thread to tear, not the bottom
3. Make sure a new needle is in the machine - one made for the material you are sewing
4. The bobbin must be installed to rotate in the correct direction in your bobbin case
5. And I'll say it anyway - tensions - the primary cause of thread breaking - Remember, there are TWO tensions in a sewing machine, top and bottom. Also, the thread you see on the bottom of the stitch is the top thread, and vice-versa.

Once placed into bobbin case, gently pull thread to the left so it comes out underneath of the metal section the screw sits on. This information is for front loading bobbins.

SOURCE: The bobbin thread breaks

if upper thread is breaking
1. needle in backward
2.upper tension to tight-check manual for proper setting
3.needle maybe bent-try rolling needle on flat surface to see if it's bent & if so replace
4.thread may hang on bobbin case-check area for lent or fragments of old threads
5. knotty or cheap thread-always use good quality thread
if lower thread is breaking
1.the most probable cause of lower thread breaking is an inproperly wound bobbin
2.bent bobbin
3.lint built up in case
4. thread catching on a spring or latch

My bobbin thread breaks too much. How do I fix it.


Be sure you are using the correct bobbin for your machine. Even though it appears to fit the bobbin case, if it is the wrong bobbin, it could cause major headaches.

Try a different bobbin. Try different thread.

Also check that the bobbin thread is wound smoothly and turning the correct direction in the bobbin case. Make sure the thread is threaded through the bobbin tension properly.

AVOID old and inexpensive, bargain bin thread!

There could be a nick or burr somewhere that is catching the bobbin thread and breaking it.

Try loosening the bobbin tension a bit. It could be too tight, especially if the bobbin thread is pulling the upper thread down to the underside of the fabric.

There could also be something wrong with the bobbin case itself that may be resolved by trying a new bobbin case (or borrow one from a friend, etc.)

How do I set a straight stitch? What is causing the top thread to break?


You do not say which machine you have. As for a straight stitch, make sure the needle is central and not in zig zag mode.
The thread can break for several reasons, such as. Incorrect tension.
:Wrong thread for the material.
: Thread in bobbin different from the top thread.
:Old thread.
: Not threaded correctly.
: Needle not inserted correctly, or incorrect needle.or the thread could be wound around the spool holder pin,
Try removing the spool and turn it around.
Hope this helps.

Thread breaking, not even threaded in needle anymore, thread gets caught on spool sometimes


Upper thread breaks
1.the needle may be bent or damaged--try rolling the needle on a flat surface to see if it's bent or not
Or the needle could be in backwards
Correct needle insertion
Correct needle insertion is mandatory for proper use of sewing machine.
Raise the needle bar to the highest point, then loosen the clamp screw to remove the old needle, place the new needle in the clamp with the flat side to the back of the machine or if using a round needle--the groove in the needle should face away from the shaft.
Push the needle all the way up to the stop or as far as it will go, then tighten the needle clamp screw
2.upper tension may be to tight--try 3 to 5
3.thread may be hanging up in bobbin case--check area for loose threads or lint
???
Lower thread breaks
The most probable cause of lower thread breaking is improperly wound bobbin
1.always start with a empty bobbin
Never wind one color over the other
2.choose thread that is identical in color & type as the one to be used for upper threading
3.wind the bobbin evenly across & in layers
4.don't wind the bobbin so full that it would be tight & hard to insert into bobbin case
5.bent bobbin--replace
6.lint built up in the bobbin case--frequent cleanings will eliminate this problem, the more often you use the sewing machine the more often it needs to be cleaned
7.thread catching on the bobbin spring or latch on bobbin case, check to see that the bobbin is inserted completely & correctly, & that you are using the right kind of bobbin

for the top & bobbin thread keep thread tails of 3 to 6 inches long pulled behind the needle before you start sewing

yes,sometimes the thread will get caught on the spool, you might think about getting a extra holder that sets behind the machine to hold those spool's that the thread get caught on, that's what I did.

Make sure the bobbin has a 3-5 inch thread tail
Then make sure the top thread has a 3-5 inch tail
Then hold the top thread tail with your fingers (away from the needle)
& use the hand wheel on the right hand side of the machine to slowly

How can I adjust the thread? I have a problem with the thread, when I start the sewing machine the tread from the top and the bottom would suddenly get tangled. Tks.


try this suggestions
check the needle to see if it's bent-roll it on a flat surface to see if it rolls correctly
check the bobbin to see if it's warped
check the bobbin case to see if there's any lint or loose threads
rethread the machine-upper thread & bobbin too---to make sure the thread is not catching on anything
make sure the upper thread has a thread tail 3-4 inches long
make sure the bobbin has a thread tail 3-4 inches long
make sure the bobbin is inserted correctly in the bobbin case
if you have your operation manual-check the tension settings & see if they are correct
