Ensure that all is clean and free of lint jams....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 Tension 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 !

SOURCE: noise from bobbin case on new Janome 4020

Check the bobbin to be sure it is inserted correctly. When you pull on the bobbin thread the bobbin should turn to the left(orcounterclockwise). If it doesn't, the thread will come out of the bobbin tension and give you loose stitches on top of the fabric. It will also make a noise because the bobbin is bouncing up and down.you will need to readjust your tension again.

SOURCE: Bobbin thread breaks after stitching

It depends on your machine. Some machine have a bobbin case that you take out a insert your bobbins. That has a screw to tighten or loosen the tension.If you have a drop in bobbin make sure you insert the bobbin the right way.

Try changing the needle sometimes over use causes burrs on the end of a needle and always remember to use proper needles to appropriate fabrics. Change needles frequently to avoid unnecessary wear on the feed dog teeth

I have a janome DC4030 the top thread keeps breaking on thicker materials,


Make sure the correct length of needle is used and installed correctly. Sometimes it moves slightly out of the holder without falling out but just enough to affect the needle eye position which can cause this kind of problem. For thicker materials use either ball point or denim needles. As last resort the top thread tension might be too tight. Adjust the top thread tension.

Bernina 780 sews great, but thread in bobbin keeps messing up while doing embroidery,


Usually, if the thread is messing up under the fabric, it is a top thread issue. This is sometimes referred to as thread nesting or bird nesting.

Make sure you are using a brand new needle of the type specifically for embroidery. The eye needs to be large enough to easily accommodate the thread size and it needs to be a sharp needle. It may help to use a needle with a larger scarf that will protect the upper thread when piercing the fabric. If the thread is not protected sometimes it will hang up on the underside of the fabric when the needle withdraws from the fabric, causing thread loops, etc.

Remove the thread from the machine. ALWAYS RAISE the presser foot and rethread from the beginning. (This releases the tension disk so the thread seats completely.) Verify the thread path is correct.

Use a bobbin thread that is compatible with the embroidery thread. Check that the bobbin thread is smoothly wound on the bobbin, that the bobbin is turning the correct direction in the bobbin case, and the bobbin case tension is threaded properly.

Retest your embroidery on a small project. If you are still seeing thread bunching up under the fabric, you need to tighten the upper tension.

My tension went out of sync now its not even picking the thread up


Try installing a brand new needle. Verify you are using the correct needle for your machine.

Remove the upper thread. Always raise the presser foot and rethread from the beginning. Make sure the threading path is correct.

Set the tension to the midway point between high & low numbers (this is usually the factory standard, although each machine may need a slight tweak and the type of fabric & thread may require a tension adjustment).

Check that the bobbin is inserted properly in the bobbin case and that the bobbin case is threaded correctly.

Retest your machine.

If it is still not picking up the bobbin thread, most likely there is a needle/hook timing issue. Take it for service.

My Janome 1600 keeps breaking threads


Is the tension too tight? Are the tension discs clean? Remove bobbin case, clean it and re-thread as this may be jammed.

After 2 or 3 stitches needle gets locked with balled thread


Lint and or thread has collected behind or under the bobbin. use a q-tip (cotton) and swipe out and around the bobbin and bobbin case. Use a can of air and blow out and around the bobbin area. Remove the spool thread from the machine and rethread the spool and bobbin thread in machine.

My needle thread keeps breaking. I've tried different thread (top and bobbin), a new needle, and I opened up the bottom plate to clean out lint. I have also tried adjusting the thread tension.


Are you sure you have got the top thread threaded correctly including the take up lever? Start at the thread spool and follow the thread all the way through the thread path checking that it is not snagging on anything enroute and that the thread is correctly through the tension device. Also tension dial should be on 4-5, if its higher this could be breaking the thread. YOu should not need to adjust top thread tension more than a half increment at any time.

Other possibility is that the bobbin holder under the needle plate has moved out of alignment and then the top thread is catching there as it goes around the hook.

If you check your manual it should give you instructions on removing the needle plate (2 screws need to come out), then you can lift the bobbin case out towards you, clean underneath with your little brush, then reinsert it. There are two little red marks on the right side of the bobbin case and a stopper, these need to be lined up. Then put in bobbin and rethread into tension spring, replace needle plate, bobbin cover, and test stitch.

Hopefully one of the above is causing the thread to break.

My Husqvarna diamond top thread keeps breaking while doing loop embroidery. It sews a couple of stitches and then you can hear when the thread breaks. Ive tried changing the needle and bobbin, and cleaning...


Hello

Primary causes of upper thread breakage:


-- misthreading: pull all the thread off and thread again, using the manual, step by step. Read each step aloud before you do it. (sounds dumb, but helps.) (And make sure you thread the takeup lever!)

-- thread has wrapped itself around a thread guide or spool pin from one of the breaks. Take the spool off the machine before rethreading.

-- bad or damaged needle. Replace with the right size for the fabric, turned correctly (backwards needles skip stitches)

-- dirty machine, especially in the bobbin case area: review cleaning instructions and do it, using brush and vacuum only

-- bad/cheap thread: should not be slubby or break easy. Try another spool.

-- top thread tension too tight. 4 is normal for most fabrics, most stitches.

Tips;

1) do a light cleaning (brush and vacuum) every day you sit down to sew.

2) replace the needle if you hear it hit metal, if you've got a really bad thread jam, if you see it deflect as you sew (for instance, sewing over the side seam on jeans when hemming). Replace every 3-8 hours of actual stitching time anyhow.

3) buy good quality thread

4) when your machine isn't sewing right, stop; take all the thread off of/out of the machine (bobbin out of bobbin case, spool off spool pin) and give it a quick cleaning. Rethread from scratch, carefully. If that doesn't fix it, do it again, then replace needle and rethread one more time, manual in hand (yah, even if you've threaded it 8 million times before). #4 is curative about 98% of the time. The other 2% often requires professional attention.

I keep having trouble...I have tried some of the solutions on this page and still not working. I'm trying to sew on a very stretchy fabric, I have put in a fresh "ball point" needle, I have...


How frustrating for you - I will assume that "very stretchy fabric" would be lycra or a jersey with lycra or spandex in it. This can be tricky fabric to tackle on the sewing machine, especially if it is very light weight, textured or open weave. So use a Smetz "Stretch" needle, not just a regular ball point and a good quality polyester thread such as gutterman or metrosene. this link is great info on sewing threads, http://sewing.about.com/library/weekly/aa102100a.htm
tally_girl_20.jpg Use a stretch stitch that that has forwards and backwards movement to put elasticity into the seam. Use a teflon coated (black) sewing foot if you can get one, otherwise use a clear plastic foot. And if fabric is really hard to control, you can put strips of freezer paper between the two layers to give it some stability and help control the fabric when stitching. Use a spool cap over the thread spool to help the thread flow off smoothly. It is possible that your fabric may just be too difficult for a regular SM and best tackled with a serger with differential feed which is why sergers are so popular, they are great for knits.

However, your top thread breaking over and over like this sounds more like the top tension discs are malfunctioning or your top thread is caught/catching somewhere in the path to the needle.

So, take a deep breath, put in a regular woven needle and get the tensions sorted on cotton fabric scraps first. This way, you take the stretch fabric out of the equasion and establish if the machine is faulting.

Have you cleaned the top tension discs already? If not, do this now - turn to zero, then run the selvage edge of a clean piece of cotton scrap fabric between the discs in a sawing motion. Is there black gunk coming onto the fabric? Keep going until it is clean. Then rethread up and set tension back to 5. (I assume you are using a good quality thread and it isn't a very old spool that has been sitting around for years? Thread does dry out and get brittle with age - I keep mine in sealed containers away from sunlight).

Also carefully check the threading path from the spool to the needle, is the thread catching on a nick in the top of the spool? or some other part of your machine, is it wrapped twice around an eyelet or the thread takeup lever. Is there some sharp piece of plastic or metal that is causing the thread to break. Lower the pressure foot and pull the top thread just before the needle. It should feel firm but you should be able to pull it? If it breaks now, I would take it to the mechanic and get it serviced.

If you can pull the thread okay, then rethread the bobbin, set the tension back to the normal number on the bobbin holder, and test sew on cotton fabric. Can you get a good seam now? If thread is still breaking now, I'd take the machine to the mechanic for a full service.

Janome jd 1822 when i'm doing zig zag, the thread is missing stitches and also my threads keep breaking


rethread the machine getting every thread guide
check the thread tension 3 or 4 is usually good
Change needle--make sure the flat side is toward the back of the machine & that it's insert as high as it will go--make sure the needle bar is raised to it's highest position
Clean under needle plate where feed dogs are for lint
Clean bobbin area for lint or loose threads
Rethread machine top thread make sure to get every thread guide
& bobbin that the bobbin is wound correctly & put into the bobbin case or shuttle correctly

here a tip about needle & thread compatability
Cut 6-8 inch piece of thread of the spool you are going to use for your project
Take the needle you are going to use for the project
& insert the thread thru the eye of the needle
& lift one end of the thread to a 45 degree angle
& if the needle is the right size for the thread it will slide down the thread
But if the needle hangs on the thread you need one size larger needle for the thread

The machine thread keeps breaking


try rethreading the machine
the top thread tension might be to tight
needle may not be inserted into needle clamp correctly
thread could be caught on something like--spool pin--notch on spool
needle may be damaged
