SOURCE: Singer Starlet 353 Thread tension

you need to do a tension assembly check.

To do this test. Pull the threadthrough the tension assembly and test it to make sure the tension is workingcorrectly.
(To do this test, adjust your tension setting to normal or medium or 5 orsomething in the middle. Raise the presser foot and pull the thread through thetension. It should pull easily!! Lower the presser foot and pull the thread. Itshould pull noticeably harder.)
If it doesn’t work this way then you probably have a pieceof thread or lint stuck inside the tension discs. To remove it, turn thetension to 0 zero and raise the presser foot.Using a small screwdriver, openthe space between the discs and spray with canned or compressed air. The stuffshould come out. Do the tension test again to make sure you got everything andthen try sewing again.

SOURCE: janome 9500 bobbin tension too tight can I adjust it

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 !

SOURCE: the top thread keep breaking. should the tension

Thread breakage is usually due to the needle in backwards, upper tension too tight or old/weak thread.

When replacing the needle, make sure that the flat side is to the right (3 o'clock position) and is pushed all of the way up before tightening.

What brand and weight of thread are you using and are you sewing with the foot or free motion sewing?

SOURCE: singer 57817 thread tension problem

Hello,

If you have Increased the upper thread tension on your machine, try these solutions.

* Decrease your bobbin tension if your sewing machine allows you to adjust it. Consult your manual.

* Re-thread your bobbin, It may be threaded incorrectly.

* Reinsert your bobbin, It may be inserted incorrectly.

* Change your thread. If your upper thread and bobbin threads are different types, try using the same thread for both.

I hope this helps.

My Singer XL 6000 upper thread is too tight and keeps breaking, when the presser foot is up the upper thread is loose, but when the presser foot is lowered the threah gets too tight, what I notice is that...


You need to loosen the tension on the machine. There is a dial that has numbers on it. The higher the dial is set, the tighter the tension is. Turn the dial to the left one number. Then try it. Do it over and over. Do not turn the dial all the way down or you will mess up your machine. Do it slowly, one number at a time and try the machine between dials.

Singer xl-400 bobbin tread to loose when momograming


It means that your top thread tension is tighter than your bottom thread, and it's pulling your bobbin thread up. You loosen your top thread by turning the dial towards the "S." You should only have to loosen it by a maximum of one number; if it's more than that, you may have to adjust the bobbin thread tension.

You do that by first turning off the machine and removing the embroidery unit. Turn the tension dial to S. It helps to use a different color top and bottom thread, with the scrap fabric a third color. Run a straight stitch and zigzag stitch and examine them. If one size of the zigzag looks like "chicken tracks" or one side of the straight stitch is a straight line, it means that side is too tight. Take a look at your user's manual on page 11. If your top tension is on "S" and it is the side that is too tight, you will need to tighten the bobbin tension, to match the top tension. Tensions are a BALANCE.

The next step needs to be done systematically and carefully. If you don't, you can really make things worse. Set your mind to doing everything step by step--don't get tempted to jump ahead. Take the needle plate off and take out the bobbin case, and locate two screws on the side. One is a Phillips screw--leave it alone. The other is a straight screw--that's the one, and you will need a tiny screwdriver to adjust it.

The rule is "righty-tighty, lefty-loosey." Remember, you are trying to match the top tension! Give the screw on the case no more than 1/4 turn, reinsert and retest. You should see at least a little improvement. Keep doing that until you have balanced your stitches, and DON'T jump ahead! The difference between too tight or too lose is often a very small turn of that screw--especially when you're close.

Two threads coming from bobbin?


try adjusting the top thread tension-one number or letter less, then
sew on a piece of the scrap fabric if you have any. to see if that helps
try changing the needle
make sure the bobbin is turned the right way in the bobbin case, I
know this may sound crazy but it can hinder the sewing, I was sewing
a skirt the other night & I turned the bobbin the wrong way & inserted
the bobbin into the bobbin case & it didn't work good,, I took the bobbin
out of the bobbin case & had multiple threads. so I had to clean the mess up & turn the bobbin the opposite way & the machine worked
just fine

Which stitch are you using?

To check thread tension for straight stitches, use different colors of thread in your top thread and bobbin. If the top thread shows on the bottom of the fabric, turn the dial counter-clockwise (towards a lower number). If the bottom thread shows on the top, turn the dial clockwise. Do not adjust the tension too much (for example, go from 2 to 2.5 if increasing the tension) at a time; test another set of stitches. Alternatively, you can adjust the bobbin tension in the reverse directions. However, it's very easy to damage the set screw in the bobbin case so do this as a last resort. Since this is a vertical bobbin case, put the bobbin in and hold onto the thread. If the thread moves when you dangle the bobbin case, tighten the screw. Loosen the screw if the thread doesn't pull out of the bobbin when you hold the unit.

For zig-zag decorative stitches lower the tension until the puckering stops. Usually the top thread will show on the bottom of the fabric.

If the tension is not changing when you turn the dial, make sure that the presser foot is down. The sewing machine may need repair. The tension mechanism depends on a spring and that can break. See the Singer site for a parts breakdown and contact your Singer dealer for the parts.

If the top and bottom fabric are not moving at the same rate, you can get a different type of puckering. You may want to get an even feed foot if there are several layers of fabric.

The manual for the 3116 is available from Singer: http://www.singerco.com/uploads/download/438_3116.pdf .

I hope this helps.

I have a singer simple 3116 sewing machine and it stitches loose upper threads. I?ve tried adjusting the tension, re threading, flipping the bobbin around, and even different fabric. But nothing seems to...


Insert a new needle, (flat side facing rear of machine), now totally rethread. Try this, with presser foot up, pull top thread, it should pull smoothly, now lower presser foot, the thread should barely move. This should seat the thread in the tension discs. If that doesn't work, call Singer at 1-800-4singer.

If the bottom tension is too tight, the problem lies with your top thread. Lower your top thread tension and it should rectify your problem
