    I agree, the most common problem is the upper thread catching somewhere, usually the spool itself. Try flipping the spool over.



  • jill May 11, 2010

    is your thread old?  is it a specialty thread?  do you have the same thread in the bobbin that you have on the spool?  is the needle the correct weight for the fabric and is the needle new and sharp?


    my first thought was that for some reason the thread is not flowing off the spool and through the machine freely.  it sounds as though it might be catching on something creating a very tight upper thread tension.

Check to make sure the there is no damage to the needle plate. A gouged plate will rub the thread when it passes and break it. Make sure the tension number is between 3-5. To check your bobbin thread, once you put the bobbin in and have it threaded properly, pull on the thread, if it has a little resistance, it is probably good, if it pulls through too easily, adjust the screw, just a very minor bit until you feel some resistance. Then try again. Sometimes it takes a little back and forth to get it right, better to go in small amounts than large leaps.

The thread keeps breaking. Could the AUTO tensioner be the problem ?


here are some suggestions, hope they help
Upper thread breaks
1.needle may 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.the needle may be bent or damaged--try rolling the needle on a flat surface to see if it's bent or not
4.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 .

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

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.

I am sewing a quilt and my needle is in the right place but it keeps breaking. Please help. Also, the thread break often.


here are something you might check
upper thread breaks
1.top tension to tight
2.thread to thick or to fine for needle
3.needle not inserted correctly
4.thread caught on something-spool pin, tension area
5.needle damaged
6.needle thread is not threaded properly

Needle breaks
wrong size needle for fabric
wrong foot is attached
needle clamp screw is loose

also check for lint & pieces of broke needle under the needle plate
also the bobbin case area -take the bobbin & case out & check for pieces of broke needle

here is a tip about needle & thread
Cut 6-8 inch piece of thread of the spool you are going to use for your project
Take the needle you are going to use for the project
& insert the thread thru the eye of the needle
& lift one end of the thread to a 45 degree angle
& if the needle is the right size for the thread it will slide down the thread
But if the needle hangs on the thread you need one size larger needle for the thread

Try inserting the bobbin in the reverse direction. Most machines take a bobbin clockwise or counterclockwise and it can make a difference. Also try a new needle, a bad needle is often the problem believe it or not.

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


Hello,
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
smoothly.

* 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.
