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.

Have you checked the top thread is correctly placed in the spring of the bobbin case?

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.

SOURCE: I have an old singer sewing machine 401A. The top

You can download a manual for $10 at www.sewingmanuals.com and it should help you. A couple of suggestions though, is your needle inserted correctly? Flat side facing the rear of the machine, fresh needle? Threaded correctly on top and bobbin area? Is your thread good not too old and the same type in bobbin and top? Did you leave a long enough tail in the bobbin thread? 3-4 inches which you hold with your left hand. Is the thread in the bobbin unwinding the right way? Are you turning the handwheel towards you, not away from you at least two revolutions or until you see the thread loop? Try these suggestions, and I am sure one will work unless your timing is off and it needs professional service.

I can sew a few stitches did it all balls up at


Thread balling up in the bobbin case usually indicates that the TOP thread is mis-threaded (usually at the take up lever). Check with your manual for proper threading path.

I was sewing with elna machine and ran out of thread. This caused the thread to ball up underneath and "jam" the machine. I cleared it out and rethreaded it, but now the top thread doesn't catch the bobbin...


it is possible that the sewing machine has a timing problem, but check to see if the needle is inserted correctly into the needle holder
make sure the bobbin is inserted correctly into the bobbin case if the machine has a top loading bobbin
if the machine has a side or front loading bobbin also make sure the bobbin case is inserted correctly into the machine.
and also make sure the top thread has not come off the thread take up lever

Sews good on top but balls up on bottom.


Check that the thread is tight around the bobbin. Make sure that the bobbin is in the right way around - the bobbin thread should double back on itself coming out of the bobbin holder. The bobbin tension adjustment is the small screw in the plate on the bobbin case that the thread passes under as it comes off the bobbin and goes out.

When sowing the thread bunches up in a ball. The inner rotary make noise, how to correct problem?


first change the needle
clean under the needle plate where the feed dogs are for lint
also clean the bobbin area for lint or loose threads
rethread the machine-top thread & bobbin

some time the top thread can come off some thread take up levers--that should be watched when sewing

check to make sure the bobbin is always wound correctly--and incorrect wound bobbin can cause sewing problems

Singer 301a sewing machine does not sew for more than 2 secs...top thread just knots into a huge ball on bottom of fabric...everything is threaded correctly and all tension set well...next step is trash...


Recheck the top thread and bobbin tension for equal balance of thread when sewing. The knotting of thread problem is usually because the tensions are too tight or too loose and/or thread may not be properly threaded. Another reason is when the bobbin thread is wind imbalanced it will cause the thread to knot-up when sewing. This problem is notorious when the bobbin is winded within the bobbin case on some machines. The bobbin thread need to be wind smoothly in the bobbin to avoid this problem.

Thread ball up


Check your bobbin area. Make sure you have put the bobbin in the case with the H logo up and the thread pulls off the spool in a counter clockwise motion. Make sure the bobbin is sitting in the case and threaded through the "catch" on the bobbin case. Then leave a long piece of thread from the bottom, holding the end of the top thread, lower the needle for one revolution using the handwheel. Does the top thread catch the bobbin thread and pull it to the top? This is done without fabric. Your checking to determine if the top thread catches the bobbin thread and pulls it to the top. IIf it does not, it is most likely hook/needle timing. f it does, gently pull on the bobbin thread and determine if it pulls through with a little resistence (checking bobbin tension). Make sure you are using correct needle -- Schmitz or Inspira needles are recommended (Universal size 80 is standard). Make sure you are using Husqvarna Viking made for your machine -- original ones were green but there are some new colored ones but all have the Husqvarna logo on them. Otherwise take it to an authorized Husqvarna Viking dealer. You can find your closest dealer at the Husqvarna Viking website - http://www.husqvarnaviking.com/us Good luck

Sewing machine XL 5500 settings


Your bobbin is probably too loose. When you set a new bobbin, stop every now and then and try with your fingers nail if it's nice and tight enough. Not extremely tight, but tight, not loose and moves easily when you set your finger between the threads.

With most fabrics (99%) the plate is fine at the the top position, just with very thick and "fragile" (satins etc) you might need to adjust it.

Settings: Tightest tension for the thinnest materials, more loose for the thicker ones, better have a test piece, it rarely goes under 5 anyway.

Bobbin threading


Unthread the machine
Open the top of the machine and take the thread and place it through one of the whole in the bobbin (from inside to outside) and pre-wind to secure the thread around the bobbin
Wrap the thread around the far left feeder knob on the top and put the bobbin on the bobbin holder in the top right-hand side
Push the bobbin to the right until it snaps in place (it will click)
On the outside of the machine, un-secure the hand sewing wheel so that it is loose
Power the pedal and watch the bobbin load
When finished, push the bobbin holder back to the left to release it and you're done
