SOURCE: Upper thread wraps around bobbin mechanism, while sewing

IT PROBABLY IS THREADED INCORRECTLY. GO SLOWLY BY THE DIAPHRAGM AND MAKE SURE IT IS THREADED CORRECTLY. ALSO MAKE SURE SPOOL PIN HOLDERS ARE IN PLACE THAT HELPS TO GUIDE THE THREAD CORRECTLY.

SOURCE: Upper thread knots up with bobbin thread when sewing a stich

Thread test
Test your thread quality to start, thread your machine and LIFT the presser foot (this opens the tension disks). Pull your top thread straight back. If you feel no tension no mater how much thread you pull, your thread is good. If that your machine passes that test, then let me know, we can go to step 2. If not, try different spool of thread, same test until you get a smooth pull (tip: always check your thread this way when you thread your machine)
Step 2:
Pull on your threaded bobbin thread while it’s in the machine. Does it pull smooth and even? If so, go to step 3. If not, try a new bobbin (bobbins get bent or distorted if wound too tight).
Clean thoroughly in the hook and bobbin case area and oil 1-2 drop is all.
Thread knotting on the bobbin can be a lot of things but here's some guidance:
Tension:
If the thread is loose on the bottom of the fabric, it's actually the top thread is too loose. Think of 2 little elves playing tug of war in your machine, one on toip and one underneath. If you have loops on bottom, the top needs to pull harder (tighten top tension)
Jamming bobbin case:
If it is damaged from turning out of place once, it could have rough spots on it that makes the thread hang on it, and keeps making it turn over and over. Use a finger nail board (fine sanding) and smoothall rough spots. Then reset the bobbin case taking care to put the notch in the bobbin case in alignment with the proper spot in the machine (basically 5 o’clock) when looking at the round area where the bobbin case goes.

SOURCE: Top thread won't pick up the bobbin thread

re insert the needle, maybe you did not put the needle up as far as it is to go. Make sure the flat side of the needle is to the back of the machine. Without any thread in the machine hand turn the wheel and look to see if the hook of your bobbin would/could catch the thread (to see if timing is right)
then thread the machine and hand turn the wheel and see what it is doing.
Your timing might be off, but I do not think that is likely. Though it is possible that when the needle fell out, it hit something hard, broke, and pushed the machine out of timing. then you need to bring it in.

SOURCE: Singer Sewing Machine model 9224. Bobbin thread

If you turn the handwheel, can you see a metal ring rotating around the outer edge of the bobbin case? If not rotating, broken gear or timing belt off.
If that ring is turning, remove the needle plate and bobbin case. As this ring now rotates, you will a finger on the ring that will pass behind the needle from right to left and it should catch the thread from the eye of the needle. If this finger, the "hook" passes above the eye, you have a timing problem.

Let me know.

Try these suggestions

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

My minghui is sawing just top and bottom is just mess can u help me???


Thanks for the question.
If your machine is not sewing on the bottom or making stacks of thread called (bird nesting) there are several simple fixes for this and some not so simple.
First you need to make sure that you are threading the bobbin into the holder correctly, Insure that you pull the end of the thread through the little slit on the side of the bobbin and that the thread is somewhat snug but not hard to pull.
Once you have done this replace the bobbin in the bobbin holder and thread the feed thread over the top from the spool or thread. making sure that you run it through the auto tensioner.
Set the auto thread tension to +1 to start, go ahead and thread the main feed through the bobbin feed so that you have both strings on the sewing deck.
Now with a piece of used material, pull both bobbin feed and Main thread behind the machine, insert your test material, drop the material tension foot onto material and start to sew a 1 inch spot.
After about one inch check to see if your machine is still nesting thread, if it is you need to add more tention to the main thread by moving the auto tensioner to +2. Now test sew again a short distance and recheck. If you still have a issue move the tension up until the nesting of string stops.
If you reach the stop. than it\'s likely that the bobbin holder needs to be adjusted.
The bobbin holder has two small screws in it generally that allow a very small screwdriver to adjust the bi metal pensioner on the bobbin holder. This is the area where you slide the string through the little slot in the bobbin holder.
You can tighten those screws until the string is harder to pull out of the bobbin holder. You may have to repeat this step several times until you get the tensions just right.
but make sure that you reset the main Thread tension to 0 before you start adjusting the bobbin tension.
If after all this work fails you may have to replace the bobbin holder to correct this issue.
There is one other fix that you can try before replacing the bobbin holder and that is to purchase more expensive thread. The reason behind this is that the more expensive thread is thicker and causes more friction in the bobbin holder..
I hope that this has helped you, I know what it\'s like not to have a working sewing machine.
Best of luck and thanks for using Fixya.com

Lil sew & sew lss202 bobbin threading?


Drop bobbin in carrier such that the thread and bobbin form "P". When you pull on thread the bobbin unwinds counter clockwise. Lay loose thread in groove on plate coming toward front of machine. Replace cover. Rotate hand wheel towards you to pick up thread. Pull upper and lower threads to rear of machine under presser foot.

Top thread tangled in bobbin.


try changing the needle---flat side goes to the back side of the machine
also check the top tension
depending on the fabric your sewing on--the needle & thread have to work
with the fabric--example light fabric needs a different needle & thread than
a heavy fabric
check to see if the thread is coming off the thread take up lever when you
sew.

The bobbin thread will not pick up. The machine had jammed and I forced the wheel and can't get bobbin thread to pick up. When I thread manually, I only get holes, no stitches. Is it a timing belt?


check your needle to see if it's bent---roll on flat surface to see if it roll correctly
on some sewing machines when the thread comes off the thread take up lever it can cause the machine to jam
also if the bobbin thread becomes tangled it can jam
check the bobbin area for lint or loose threads
try having a top thread tail & bobbin thread tail of 3-4 inches
try holding the top thread tail & turn the handwheel on the right side on the machine manually & put the needle down into the bobbin area & see if the bobbin thread will pick up that way
