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: bobbin doesn't fill in bobbin winder

The bobbin winder question is a frequent one and it is very easy to solve. If you look at the shaft where the bobbin sits on the bobbin winder, you will notice that it has a slot in the middle of the shaft, an opening if you will. This is where you use a flat screw driver and open that space more to give more friction to the bobbin so it is not loose on the shaft. That slot was made for that. There are different bobbins on the market so thats why the slot is there. If it is too tight, grab a pair of pliers and close the gap. The metal of the bobbin winder on that shaft is malleable exactly for this reason. No need to put plastic bag material or anything like that. Use it as it was intended for.

SOURCE: thread or bobbin tension

Thread tension. Beware of adjusting the bobbin screw. Pfaffs maintain their tensions just fine without adjusting the bobbin tension, unless you're using some crazy thick or fine thread. If you must change your bobbin tension, you would be well-advised to buy an extra bobbin case, because re-calibrating your tensions after changing them can be less than fun.

Increase your top tension, and your looping should cease. I normally keep my tension around 4.5. Also make sure you're using a good quality thread, and that there's nothing in the upper tension assemblies. Sometimes a tiny piece of debris can keep the top tension from applying enough tension, so turning the machine off and blowing some canned air in there can help as well.

Good luck,

SOURCE: The lower (bobbin) thread on my brand new Brother tangles

Please TRY the solution BEFORE giving your considered rating.
Specific detail on bobbin case adjustment (with picture) near halfway down reply, the remainder will help you achieve a balance of top and bottom tensions.

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 consistent diameter with good thread, and less compensating to be done by your tension plates and less thread breaks

When trying to load the bobbin with thread, only top half threads and is tangled. Has worked great till now.


Difficult to assess without a make & model.

The machine has a tensioner for the bobbin winder. Make sure that you are threading that tensioner before taking it to the bobbin winder. Also, sometimes the thread should make a complete loop around that tensioner (consult your owner's manual). Check that the thread spool is spinning the correct direction--most often the thread spool turns counter-clockwise on the spool pin. Running the thread the wrong direction could cause thread kinks or the thread plies to separate. Slow down the speed that you wind the bobbin. Fast speeds will cause the thread to stretch. Plus, if something goes haywire, you won't have a bobbin bouncing or thread flying all over the sewing room before you can stop the machine. Frequently, the bobbin will fill more in one area of the bobbin. You can gently guide the thread by pushing it up or down lightly with a pencil tip or other object to even the thread distribution on the bobbin.

When I try to fill my bobbin the thread gets all balled up on top of the bobbin instead of filling it. What should I do?


Consult your owner's manual. Chances are you may be threading the thread incorrectly. Make sure it is going through the bobbin winder tension guide before going to the bobbin winder mechanism.

If it continues, the bobbin winder may need a height adjustment. I had that issue with a machine that the case surrounding the bobbin mechanism was slightly misaligned. Once it was fixed, the bobbin winder worked perfectly.

Thread bunching and bobbin winder quit


This sounds a lot like you've forgotten to lower the presser foot. (this leaves the tension discs open and causes serious issues below the material.) Double check that and if still having issues post again.

Bernina 135 bobbin winds unevenly


If you are finding that the bobbin is winding with more thread towards one edge of the bobbin than the other, the bobbin winder motor needs to be adjusted so that the angle of the winder shaft is properly aligned with the tension disc next to the head cover. Unfortunately, unlike many of the other models, you have to remove the covers on the Activa range to get at the adjuster. There is a spring-tensioned screw just to the left of the bobbin winder motor that adjusts the angle of the motor and therefore how it loads the bobbin. If the winder is loading the bobbin with most of the thread towards the bottom edge, the screw should be turned clockwise and if most towards the top, it should be turned anticlockise. Make adjustments until the thread is winding evenly or, at least, towards the centre of the bobbin.

If you are finding that your bobbin is being loaded somewhat randomly, make sure you are using the vertical spool holder to hold the spool and that you've got a foam pad under the thread spool. Route the thread through the thread guide before winding around the tension disc in the correct direction (see the arrow on the case) and ensure that the spool and thread do not vibrate unduly when the bobbin is being wound. If you let the spool vibrate whilst the bobbin is loading, it may result in varying tension on the thread and uneven winding onto the bobbin.

Wind the Bobbin
For the usual jobs, it is the best to use a medium sized thread.
2. Disengage the flywheel by unscrewing the coupling knob as far as it will go.

3. Place the bobbin on the bobbin winder, and push the bobbin winder to the right.

4. Pull out one of the spool pins and place the spool of thread on it.

5. Pass the thread through the bobbin winder tension discs, as indicated.

6. Wind the end of the thread around the bobbin by hand, in the direction indicated.

7. Wind the bobbin, at a medium speed by pressing lightly with a finger on the spool so as to stretch the thread better and thus fill the bobbin to a maximum. The full bobbin stops automatically.

8. Re-engage the flywheel by tightening the coupling knob.

9. Cut the thread and remove the bobbin from the bobbin winder by pushing the latter to the left.

Kenmore Sewing Machine model # c877.15


I have a Kenmore as well ,I hope that this will work for you ,too bad that I don't live close to you otherwise I would give a hand. This is the way I fill the bobbin on mine. Mine is located on the top right ,I put the thread into the bobbin hole leaving a small piece of thread hanging for me to hold when I begin the winding, I pull the wheele out to stop the needle from moving while winding, when I am done just push it back in .I run the thread from the spool into the top left it looks like a U turn with a screw go around that without winding just pull it into the bobbin hole. press the foot control and it will begin winding .
