The bobbin will tread at all! no fabric is caught-up. motor run but not threading.

If you have an a self wind bobbin make sure the bobbin winder is all the way down and no thread caught under it, your machine should be able to cope with thick fabric, slacken the pressure on the presser foot

The top thread breaks

1. the needle thread is not threaded properly

2. The needle thread tension is to tight

3. The needle is bent or blunt

4. The needle is incorrectly inserted

5. The needle thread & the bobbin thread are not set under the presser foot when starting to sew

6. the threads were not drawn to the rear after sewing

7. The thread is either to heavy or to fine for the needle

8. Try a different spool or cone of thread


Bobbin thread breaks


1. There is a right way & wrong way to insert the bobbin in the case --when you insert the bobbin in if it doesn't stitch correctly turn the bobbin over see if that helps or bobbin case is not inserted correctly


2. Lint has collected in the bobbin holder


3. The bobbin is damaged & doesn't turn smoothly


4. Lower thread tension is two tight

if the sewing machine has a top loading bobbin, you may have to have the sewing machine checked to see if there is something wrong with the bobbin case or the hook and hook race.
I suggest try a new needle--one for the fabric being sewed
also try another bobbin
rethread the sewing machine top and bobbin, using every thread guide.

try rethreading the machine top & bobbin
change the needle--flat side to the back of the machine, make sure the needle is the right one for the fabric being sewed
clean under the needle plate & in the bobbin area for lint or theads

change the needle
clean under the needle plate & in the bobbin area for loose threads & lint
rethread the machine top & bobbin

Hi. So is this a horizontal hook? Where is the thread getting caught beneath the needle? Maybe on the hook? Check your upper threading to make sure the thread passes through the thread take-up lever. If thread is not through the lever, it wont get pulled up , which can lead to multiple thread loops getting caught on the hook, not pulling off after the rotation.

Do you have the bobbin thread going the right way, according to owners manual some go clock wise some go counter clock wise when you pull the thread after bobbin inserted in bobbin case

It could be different things, the tread may not be locked in the top tension, you may have treads all wrapped up around the bottom bobbin. Take out the bobbin and look, re-thread the entire machine.

I had similar problems when I first started sewing. Try adjusting the tension in your thread - less tension for lighter fabrics, more tension for heavier fabrics. This will stop the needle from pulling the threads in the fabric.

As for the thread getting bunched up in the bobbin - this is most likely because your bobbin is the wrong size for the machine, or that you did not thread the bobbin properly. Try re-threading, this time making sure you pull the thread into the bobbin container tightly. This should stop the bobbin from jumping around the container and spitting thread.

Hello,
Here are a couple of solutions to try.

* Try re-threading your machine. It may be threaded wrong.

* Raise your feed dogs
If your machine has this feature.

* When you start to sew a seam, hold the upper and bobbin thread tails back and out of the way as you sew your first couple of stitches. This will prevent them from getting caught in your machine.

I hope this helps.

The tread only breaks in the needle. what can i do . i don't get to sew anything . I tread the needle and get everything ready and start the machine and as quickly as that the tread is broken and the machine has not sewn at all.
