SOURCE: bobbin tension

This is an issue of your upper thread tension, so take a look at this generic tension solution

If you are in a pickle with your bobbin case, check top tension and bobbin case are free of lint, reset the top tension to 4, and adjust the bobbin tension to suit......some more detail on how to do that, is here

SOURCE: WHITE Jeans Machine model 1475 thread tension problem

Ensure that all is clean and free of lint and jams, this is the most likely cause....now for tension troubleshooting .......

This solution is for tension problems...if you cannot form any sort of stitch, the issue is quite different, so please let me know if you need a different problem solved.....

It is quite long, but just work through each section in order.
The "knotting up" can reveal a lot. If you have loose threads on one side or the other, the tension on the opposite side will be the culprit.

QUICK SUMMARY FIRST:
Ensure sharp new needle,
Thread guides and Bobbin are Clean & Clear of lint
Set Top Tesion to 4 ....then....
Balance Bobbin to suit.

TOP THREAD TENSION:
If the looping threads are on the underside as you sew, it is the top tension. Top tension ought to be between 4 & 6 (this variation to allow for the different weights of fabric in your
projects).

IS YOUR NEEDLE SHARP ?
If you are using a needle that has seen quite a deal of work, or you suspect it may be blunt, change it for a new one !

TOP TENSION & GUIDES:
Make sure that when you thread the machine the presser foot is up so the thread goes between the discs and not to one side, top tension between 4 and 6, and that you have threaded through all the guides, including the last one, usually on the needle arm, just above the needle clamp.

It may be there is lint trapped between the discs, this will keep them slightly apart and reduce the actual tension, sometimes dramatically.

If tensions appear correct, and the thread is definitely in the channel between the discs, but still too loose and looping, try raising presser foot and remove your thread.

Now, with a 2" (50mm) wide strip piece of fabric 8 - 10" (20 - 25cm) moistened with methylated or denatured spirit, gently insert the fabric strip and clean between the discs with
a see saw / to and fro action.

In the worst cases, gentle use of a needle to pick & remove the jam may be necessary, but be very gentle and make sure the tension is set at Zero and the presser foot is raised, (to
disengage tension plates).... do not gouge or score the plates, they need a polished surface to work correctly.

BOBBIN TENSION:
Far less common, but if the loose threads are on the top, it is bobbin tension that is loose, it too may have lint in the spring and be giving a "false" tension.

I would not recommend fiddling with bobbin tension without good reason, it may end up with missing small screws and spring pieces, however, you can take the needle plate off to clean
the hook race area (where bobbin case sits)

...this is just good housekeeping, my wife does this every time she replaces the bobbin....

just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint. If there is a significant amount of lint, use a vacuum and small brush to get the worst.

Then wipe all this area with a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit, especially if there appears to be fine dirty deposits....oil and lint combine to conspire against you.

If it seems likely that you ......really ....do .....actually .....need .....to adjust the bobbin case, first check there is no lint trapped in the metal spring where the thread is tensioned.

TOP LOADER:
Drop-in Bobbin case will look similar to this image with the tension screw in the middle of the metalwork....

4c76dc1.jpg ...the other screw at one end is holding it all together, so beware....it is not a tragedy to undo the whole lot and clean it, but very gingerly and lay the bits out in sequence and orientation, or you risk tearing your hair out !

FRONT LOADER:
....this is a bobbin case from a front loading machine and works in a very similar fashion to the top loader with drop in bobbin, again, if you dismantle it, take care so you can put it all
back properly.
165ca5c.jpg FINISHING UP
GETTING THE BALANCE RIGHT:
When you are certain there's no trapped lint in top tension or bobbin, set the top tension to 4 and the bobbin tension to a point where you just begin to feel resistance.

Try using good quality thread of contrasting colours so you can more easily spot the changes.

Set your zigzag to one width less than maximum (eg. 5 of 6 ...or... 4 of 5 etc) and sew a sample for a few inches and check the result.... adjust the bobbin tension screw very little at
a time, perhaps 1/16 of a turn.

You may find you are playing with this balance for some little while and if you are putting the needleplate on and off each time begin to think it cannot be correct to do this.....BUT....it is,
and eventually, you do get a "feel" for the correct tension and then it happens quite quickly.....as a user you won't be doing it very often unless there is lint built up (or are there small hands at work around the house !?!?!)

OTHER ISSUES:
If you live near the ocean as we do, salt air can play havoc with metalwork inside and out, so to help minimise this, keep a few small packets of dessicant (silica gel) in your machine
case....no case ? then make some sort of cover !

Same applies in any damp or humid environment, keep your machine dry and dust free.

Budget for a proper full service every couple of years (more often if heavily used) and if you don't use your machine for a few years, be aware that old oil will dry out and combining with
dust and form a "clag" like glue (another reason for some sort of cover, even a teatowel !)

FINALLY, A WORD ON THREAD:
If it is worth spending the time, energy and money on making something that you would like to give lasting enjoyment......use quality thread, .......it may seem to cost a little more at the
time, but the results, ease of use and added longevity will be worth the extra, and as a bonus, your tension troubles may be fewer and further between, because there is a more consistant diameter with good thread, and less compensating to be done by your tension plates and less thread breaks !

SOURCE: unable to adjust tension,

Sounds like the bobbin thread is not inside the tension on the bobbin case. This normally happens when the bobbin is upside down. Insert the bobbin and pull on the thread.The bobbin should turn counter clockwise.

Top tension back to 4 and leave the bobbin tension as is.

Make sure you have a new needle for the type of fabric being sewn installed with the flat side to the back of the machine. A bent needle can sometimes go unnoticed.

Always thread the machine with the presser foot up and this will give proper tension to the stitch.

Check the manual to be sure you are threading correctly (always with the presser foot up) and that the bobbin thread is feeding in the correct direction from the bobbin spool and through the guides.

Take hold of the thread at the needle as you lower and raise the needle to pull up the bobbin thread. Take both thread ends under the presser foot and to the back of the machine.

What is the problem when sewing the top thread can be pulled right out and the material puckers up


So, it sounds like the bobbin thread is coming to the top of the fabric and the top thread simply lays on top of the fabric. Just a hint: If the thread problem appears on top of the fabric, it is usually a bobbin thread problem. If the thread problem appears under the fabric, it is a top thread problem.

Is the top thread tight, ie pulling the bobbin thread up? Try loosening the top tension.

If that doesn't resolve the problem, then you probably need to tighten the bobbin tension.

Brother SE400 :When I pull on the fabric's sewn part one of the threads slides back and forth. I can then pull on one of the threads-it slides out and the other thread is easily lifted up. How to fix?


Your stitches may be too far apart. But, most likely the issue is that the tensions are not correct. If one thread lays in a smooth straight line on the fabric, the other thread tension is too loose, ie the bobbin thread lays on the fabric and the top thread is going all the way through the fabric and shows on the bobbin side, then the top tension needs to be tightened. The tensions are correct when both threads meet in the middle of the fabric.

I have a brother PR1000 and on the test stitch there is too much bobbin thread showing underneath. do I adjust the tension in the top thread or the bobbin tension?


Yes Adjust to more tight see what it'll do.
Bottom bobby is too tight or upper thread control is too lose.

Good luck

How do I adjust the bottom thread tension on the 2 needle cover stitch?


Go back to the tension adjustments that were doing well with other fabrics.
You may need to go to a smaller size needle, and a finer thread. Sometimes I use a wooly nylon in my looper because it is very stretchy, but be careful when you pull it through as you are threading it because it will also break easily if you don't have your tensions full open as you are pulling it through.
Start out by buying a sheet or roll of Solvy. You can either cut it into strips to lay on top of the material as you sew or under it if you prefer. It should make the material lay flat as it sews. I have used tissue paper before under it to make it lay flat and keep it flat to make the looper thread stretch itself out as it sews.
If your looper thread tension was too tight on other fabrics too, that is a whole other problem.

Top stitche is to tight and bottom stitche is to loose


Meaning you have adjusted the tension for the top thread as well as the bobbin?

Use two distinct colors of thread - one for the top and one for the bottom.

Thread the machine with the presser foot up.

The two threads should meet in the middle of the stitch with neither obvious on the opposite side of the seam.

Set the top thread tension to 4 and adjust the bobbin as needed.

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.

BOTTOM STITCH IS ALWAYS LOOSE


If the top stitch is loose, then you need to tighten the bobbin tension: if the bottom stitch is loose, tighten the top tension. Hope this helps. It could also be the size needle and thread you are using for a particular fabric. Different fabrics require different notions.
