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: thread tension on Babylock Esante2

Try a wing needle, it will keep the vinyl from pinching the thread. Don't be afraid to crank up the upper tension all the way if you are using heavy thread.
Hope this helps.

SOURCE: thread tension for regular seam sewing

oil the shaft for the presser bar and keep moving it up and down(it may take a while) until it moves freely. Always use Sewing machine oil Not 3N1 oil.
Tension:
If the thread is loose on the bottom of the fabric, it's actually the top thread is too loose. Think of 2 little elves playing tug of war in your machine, one on top and one underneath. If you have loops on bottom, the top needs to pull harder (tighten top tension). If you have loose thread on top your top tension is probably too tight and your bobbin thread too loose

are you turning the little screw in the piece that holds the bobbin? That is how you adjust the tension for the bobbin

SOURCE: Needle thread looping underneath, threads not interlocking at all

If the machine is now threaded, lift the presser foot.

Now, pull about 10" of thread through the needle.

The next time you thread the machine, lift the presser foot first.

When the presser foot is up, the tension control opens and allows the thread to "seat" into the control, then when the foot is down the control closes to the indicated setting.

When threading the machine with the foot is down, thread does not enter the tension control and when you start to sew, there is no tension on the thread.

No tension = loosey, goosey, loopy stitches underneath.

Because the lack of tension on the top thread, the bobbin thread cannot lock a proper stitch.

I have multiple threads coming out the bobin space and making a mess of the back side.


called bird nesting and is a result of too loose a needle thread tension
if you use an automatic tensioner or using the numbers
and you still have a problem, the correct tension is a resistance to you pulling the thread prior to threading the needle

Where should upper tension be to start out with a thompson mini walking foot pw201?


I'd want to check to be sure the thread is not getting caught on anything, which can mimic upper tension issues. Check the thread path, all the guides, the spool pin, the take up lever and needle bar, for nicks or wrapped up thread.

Tension discs can wear out with age. I'd try cleaning them, fold a thin pieces of soft cloth and gently work it between the discs. Should remove anything stuck in there. Just a touch of one of the silicone thread lube products may be helpful. I'd apply it to a piece of thread and then work the thread through the discs, rather than apply the lube directly to the discs.

Walking feet themselves usually don't need anything special in terms of tension. But you do need to be able to sew a balanced stitch.

Using a thread coloured differently for bobbin and top helps you see if it's balanced. All one colour on top, all the other colour on the bottom, is what you want to see. If you see pops of the other colour on top or bottom, there's a problem. If you see the bottom thread on top, or vice versa, there's a tension problem.

Thread damaged by an burr in the needle eye can fray and mimic upper tension issues too. I always try replacing the needle with a brand new one, which sometimes fixes all sorts of things. Brand new is best, not just another needle.

If none of this helps, then you may be looking at needing a new tension mechanism, or rebuilding the one you have. Best of luck.

Brother cs6000i thread tension issue


Logically, the top thread should not be affected by a walking foot as the thread operates independently of the presser foot.

Suggest removing the top thread totally from the machine. ALWAYS RAISE the presser foot and rethread from the beginning. Verify the thread path is correct.

Check that your walking foot is installed correctly--the fork-shaped piece needs to encircle the needle clamp screw.

If you continue to experience problems with the walking foot but none of the other feet, recommend contacting a Brother technician.

My problem is with the bobin. The machine worked well two days ago. Now when I try to sew , the bobin thread is becoming caught in the lower area and produces tension that stops the machine after about two...


With out looking at the machine it is hard to determine the exact problem, but make sure your bobbin thread is placed in the bobbine case corretly, and pulled through the little tension area on the bobbin case.

Next make sure the upper thread is in the tension discs, if not this can also cause you a problem, plus if possible used a little canned air (with the pressure foot up, machine unplugged and thread removed) blow out the tension area.

Good luck.

How to adjust the bobbin tension?


On a sewing machine, the first "knob" in the threading process is usually the tension.

Try threading the machine with the presser foot up, first. Sew a few stitches and then make adjustments as needed - right is a tighter and left is looser when turning the tension adjustment.

I would recommend buying sewing machine. These little gadgets are cute, but they just don't do that well and are not worth the stress they create.

Problem with spool Thread, please suggest a solution!


This is a tension problem.
In addition to the top thread having a tension adjustment there is the facility to adjust the tension of the bottom(bobbin) thread.
Both these tensions need to be correct to get a balanced stitch and to stop the loose threads underneath the cloth.
It is almost impossible to explain how to adjust the bottom tension you need to be shown.
Somewhere in your manual it should explain how to do this.
