Re: bobbin help please!

Take out the raceway and check for broken threads/lint. Unthread the machine and put in a new needle taking care to insert it correctly. It may be that the needle is slightly bent. Put everything back carefully and check it is running smoothly with NO THREAD first(no bobbin thread either-use an empty bobbin). This will prove there is nothing catching. If it catches when you thread it then you are having a problem with incorrect threading.

Every time I use this machine something else is wrong with it :-(. Now the bobbin thread us bubbling up in the back of the material and there is a grinding sound as the needle hesitates to move. What

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

I have a brother ls-2125 sewing machine. the upper thread is not catching the bobbin thread properly. help please

  1. Tension
    • Your sewing machine tension controls the rate at which the thread is fed through either the upper section of your machine or through the bobbin case. If your upper or bobbin threads aren't threading properly, sometimes adjusting the tension will correct this problem.
    • Your sewing machine works by passing the upper thread through the needle of the sewing machine at precisely the same time the bobbin brings its thread to its uppermost position. If either the needle or the bobbin thread reach these positions too soon or too late, the threads won't interact and create the knots that make the seam. You can throw off your timing by sewing too many layers of fabric or hitting a pin with your needle. See you sewing machine repair facility to correct any timing issues.
    • Thread can get snagged or caught in the upper section of your machine or on lint pieces in the lower bobbin section. If your threads aren't catching properly, you may be able to fix it by unthreading and rethreading both your upper thread and bobbin threads.

I have a brother sewing machine. i threaded and have rethreaded and threaded the bobbin over and over. it will not move the fabric and botton thread will not catch onto top. what am i doing wrong?

Brother machines are usually a very good brand. Sounds like you are having a small problem with threading..........I know how frustrating that can be!
Start over....totally from the beginning. First, clean the machine of all dust, I use a small paint brush to remove lint from the bobbin case area. Oil the machine. Remove all the thread from the machine, use a different bobbin and rewind it with new thread. Make sure the bobbin thread is the same as the thread you use to thread the upper needle with. Use a new needle that is the appropriate size for your sewing project. Check to make sure the feed dog is moving when you turn the wheel that raises the needle up and down. New needle, new bobbin, new thread......before you place the fabric under the presser foot (and with the presser foot raised), turn the wheel one complete rotation to allow the upper needle thread to catch the bobbin thread. Gently pull both threads out towards the back of the machine, making sure the bobbin thread is now coming up through the little hole in the feed dog plate. Place fabric under the presser foot, lower presser foot and as you slowly start to sew, make sure you have the bobbin thread pulled with slight tension out from the back of the needle. This will take up any slack in the bobbin thread and keep it from making a knotted mess. Good luck, I hope this helps.

My Necchi 4595 has never really worked properly,.,.,the lower thread (bobbin) is very loose and then the thread breaks,,,I've tried to adjust the tension, but maybe I'm doing that wrong.

I also own 2 necchi sewing machines, my mechanical is a 4595,,
lower thread tension
to test the bobbin tension, remove the bobbin case & bobbin & hold it by suspending it byb the thread, **** it once or twice, if the tension is correct, the thread will unwind by about an inch or two.
if the tension is too tight, it does not unwind at all, if the tension is too loose, it will drop too much.
to adjust the tension,, left is loosen & to the right tighten

thread breaks
rethread the machine making sure to get all thread guides
top thread tension usually 3 or 4
replace needle- make sure the needle is inserted correctly
some needles don't work with some thread, here's a tip

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

My wife has a model 9110 sewing machine. It has stop picking up the thread from the bobin. Can you help on this fix?

Put new needle in

Make sure you have a 3-5 inch thread tail on both top thread & bobbin
Then hold the top thread tail with your fingers (away from the needle)
& use the hand wheel on the right hand side of machine & slowly lower needle into bobbin area & see if it will pick up the bobbin thread that way

rethread the bobbin,,also check the bobbin area for lint or loose threads

if none of these suggestions work, then the machine could be out of time & would need to be repaired

I was sewing along fine and then all of a sudden my thread started "birdnesting" I have rethreaded the machine as well as the bobbin. It works great on a practice run but as soon as I go back to my project...

Yes, VERY frustrating! When this has happened to me it has always turned out to be a tiny bit of thread caught in the bobbin assembly. I've rethreaded and rethreaded but could only solve the problem by taking the bobbin assembly apart and finding and removing the caught thread. I use a bright flashlight to help find the caught threads.

Good luck and I sure hope this helps!

Morse 6300, the thread keeps breaking every attempt i make

Change your needle, make sure the needle is new. and change your thread. Use a high quality thread and rethread the machine carefully, following all the guides. Also, check your tensions. I bet it is the needle tho.

The bobbin is getting caught and needle is jamming

This sounds like there is cotton stuck in the bobbin holder. Check it thoroughly. Take the bobbin out and turn the wheel to lower the needle a few times. This will show up any thread caught. Pull it out gently. You may have to perservere to get it all out.
