Make certain the bobbin is inserted correctly into the bobbin case. If it is, be certain the bobbin is wound tight. A bad wind will cause the loose threads you mentioned. If both of those options are all right, check your upper tension. Generally, it should be set at 3. Also, make sure the needle is inserted correctly...the groove on the face of the needle should be facing the front of the machine (it is actually a thread guide). And last, has the bobbin case been removed and cleaned? If not, this could lead to "messy bobbin threads." I hope one of these suggestions is THE one for your problem. Good luck!

I checked my thread and bobbin watch the video and my machine keep bunches the bottom stitch


Is it really the bobbin thread that is bunching? Generally, thread messes under the fabric are the fault of the top thread, and thread messes on top of the fabric are a bobbin problem.

Top thread bunching under the fabric is called "thread nesting" or "bird nesting" but I prefer to call it thread "barfs." Most often, it occurs because the top thread has not been seated completely in the tension disk.

Install a brand new needle.
Remove the top thread from the machine.
RAISE the presser foot and rethread the top thread.
(Verify the thread path is correct.)
Set the top tension disk at the midway point.

Retest your machine. Tweak the top tension if required.

Bobbin thread bunching up on bottom side od material while sewinginto a mess, while top thread fine. HOW DO I fix this, please.


Hi, this is a lack of lower tension. Check to make sure your bobbin is seated correctly and that you have used the correct thread path. Check the tension by drawing some thread from the bobbin with your hand, if it reels off too easily, the tension hook for the bobbin is too loose, tighten it down a tiny bit with a small screw driver and try again. If the bobbin tension is normal, than the problem may be your upper tension, if it is too tight it can cause your bobbin to snarl. If a tension adjustment does not fix the problem, you may need to seek a specialist.

It just started sewing upside down it was fine earlier, I have just rewound the bobbin


1. You will likely need to adjust the bobbin tension. Make sure that you have placed the thread under the tension spring to start with.
2. If it is bunching up on the bottom your tension on the bottom is too strong. Before you do anything you can increase the top tension to offset this so you won't need to mess with the bobbin if it isn't a great amount.
3. JUST FOR INFORMATION: When you change threads they are either thicker, thinner or the same. This will require most of the times to adjust the bobbin.

My bobbin thread is bunching up underneath. I have taken the bobbin out and the bobbin assembly out but it still is doing it.


Gayle,

In a sewing maching, for the thread not to bunch up, there are two thread tension tighteners. One each for the bottom and the top threads. The top thread tensioner is a nut that tightens or loosens the thread tension. The thread passes under this nut. While for the bottom thread it is two screws on the casing for the bobbin. These two screws hold a small strip of metal to the casing and the thread passes under this strip.

To be able to get proper tension on both the threads you have to strike a balance on both the top and the bottom threads. If the difference is not much then you can do with varying only one of them, usually the top one for ease of functioning.

Since you say that the thread is bunching uo on the bobbin side, ie, the bottom, means that the top thread is too tight and must be loosened. You cant do it in the first go. It may take you a few attempts to get it correct, so do not loose heart if it is taking time.

All the best.

The bobbin thread keeps bunching up on my 990 machine


It is probably not the bobbin thread that is "bunching", put different color top (maybe red), and bobbin (maybe white), thread in the machine and sew. If the top thread is messing up on the bottom of the cloth you have 3 possible solutions. Here are the solutions in order of probability:
1 - You have not threaded the UPPER thread correctly. Read your book on threading.
2 - Your UPPER thread tension is too low. Try setting it at 5 or so.
3 - Your shuttle is damaged. Get a new one.

Sewing a bunch of thread from the bottom, this stops the machine from actually sewing


Yes, it does. There are a couple of reasons the bobbin thread could be bunching up on the underside of the fabric. It could simply be that the machine needs cleaning. Take the bobbin assembly out, brush all the old lint out as best you can, reoil the machine once it's all clean, and make sure there aren't any little bits of thread caught in the bobbin assembly. Rethread the machine (carefully) and change the needle. This solves the problem usually--especially if the machine was sewing along fine and the problem develops suddenly. '
The other thing to check is your tension. It could be that the top tension is too loose. But different color thread in the top and in the bobbin, stitch a few inches (be sure to held the top and bobbin thread ends behind your needle as you start to stitch) and check. WIth the pressure foot down, adjust the tension, and stitch again. Keep stitching, checking, and adjusting until you see little if any bobbin thread on the top or top thread on the bobbin.
Another thing to reminder: use the appropriate thread and needle for the fabric you're sewing.
Let me know if this works, ok?

THREAD GET BUNCHED UP UNDERNEATH THE FABRIC, THE STICHES SEEM TO BE INCOMPLETE THE TOP LOOKS GOOD THAN I TURN IT OVER AND THE THEAD IS BUNCHED AND LONG LOOPS OF THREAD ARE LEFT. THANKS LOU


Hi Lou! This sounds like a tension problem--the tension on the top thread is too loose. Try using different color threads on the top and bobbin, then carefully rethread everything. Stitch a couple of inches and check the underside. If the top stitches look fine and the bottom ones are loose and loopy, and with the pressure foot down, tighten the tension. Move the knob or dial (whichever you have) just a little bit. Sew a couple of inches more, and recheck. Continue to sew and recheck, gradually tightening the tension, until you see little if any bobbin thread on the top or top thread on the underside of the fabric.

Let me know if this helps, ok?

Bobbin thread bunches up creating a tangled mess under the plate


This could either be due to the bobbin being wound too loosely, or the tension on the top thread is too loose. This just happened to me the other day, and I thought it was the bobbin thread, but then I put another bobbin in with a different color than the top thread (this is a huge help in diagnosing thread issues), and I was surprised to find that it was actually the top thread that was a big loopy mess on the underside of the fabric. I fixed it by tightening the tension on the top thread (quite a bit), and everything was fine.
