SOURCE: upper thread getting tangled in the bobbin

Always remember T-N-T. Thread, Needle, Tension. Assuming its threaded properly, is the needle all the way in and facing the right direction? These symptoms also suggest the bobbin may be in the bobbincase upside down thus turning in the wrong direction. Hope this helps.

SOURCE: Machine not sewing

Make sure you have threaded the machine from right to left, it sounds like the needle thread is trapped under the lower looper thread and cannot form a stitch.........start the threading over from scratch like this:

  1. Lower Looper
  2. Upper Looper
  3. Left Needle
  4. Right Needle
Is there a diagram for how to thread on the inside of the door ?

Follow that slowly and carefully to make sure you have not missed any thread guides on the way, as each one needs to be followed through to ensure correct tension and thread progression.

If you are certain that all threaded correctly, did you have a fabric jam and pulled it loose ? If so, the timing may well be affected.

Post an update and we'll get this right.

SOURCE: My bottom thread is loose when sewing a straight stitch

Please TRY the solution BEFORE giving your considered rating.




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 !

the problem is always on the other side of the fabric - if thread bunches up underneath, the top tension or threading is wrong

How to adjust tension on lervia sewing machine


Tension is a balancing act between the upper tension and the bobbin tension. Balanced tension (which is not always necessary) is when the two threads meet between the layers of fabric. Not all unbalanced stitches are a tension problem. You can have loops under the fabric from a failed take up lever, improper clearance between the positioning finger or even a burr or lint. First I check the upper tension. If you can not make the upper tension normal pinching the thread after it comes off the spool will act as a tension device. If this solves your problem then start with cleaning.

You may have lint between the tension discs at the top next to the take up lever. Clean this out with the presser foot up. Next install a new needle size 80 and thread the machine. When you lower the presser foot and pull the thread the spring steel the needle is made of should bend 1/8 of an inch at normal tension. Between 3-5. If this does not happen turn to a larger number on the tension assembly. If this does not deflect the needle as you pull the thread to the left rear of the machine your tension assembly needs repair or replacement.

The bobbin tension is controlled by a spring on the bobbin case or bobbin basket (depends on the sewing machine). This spring can also get lint under it. The lint can hold the tension discs open causing no tension. This may be the problem if you see the lower thread pulling up to the top of the fabric. Normal tension on the lower thread is usually 150-200 grains. That may not mean much to you and you may not have a scale to measure that. One simple trick is to take a wooden clothes pin and glue 3 pennies to it. I then use this as a weight to set the bobbin tension. I clip the clothes pin to the thread and set it on the work bench. Next raise the bobbin case or bobbin basket without touching the thread or bobbin. Then tighten the tension screw on the bobbin case until the clothes pin lifts off the work bench.

This gives you a good place to start on balancing the tensions. Set up a straight stitch at the mid range of 2-3mm long and sew. Turn the upper tension dial to the mid range 3-5 and observe the stitch. If the bottom of the fabric shows too much top thread tighten the upper tension. If the top of the fabric shows too much lower thread loosen the upper tension. I recommend playing with your tensions to learn what too loose and too tight a tension look like. Sometimes we want the upper tension really loose to do a basting stitch. If you want to pucker (gather) you can create a long stitch and play with the tensions. A tight upper tension will pucker thin fabric. You can also gather fabric manually by using a long stitch and a loose upper tension then bunch the fabric together on the loose threads.

After all that it may be easier to take this to your local dealer and ask for advice.
Have a great day and keep on sewing.

When I embroider with my Pfaff Creative 2 the top tension pulls bobbin thread up too much. I changed toe tension on top but it still does the same thing. How can this be fixed?


Suggest you do rethreading ,then test the stitches on straight stitch. If top stitches is loose you have to reduce the upper thread tension, if the bottom stitches is loose you have to increase the upper thread tension. Adjust accordingly till you can get a perfect straight stitch. If okay then you can continue your embroidery work.

12 wt thread


12 wt thread generally will not work well in the bobbin...


"Aurifil 12wt Thread
Aurifil 12 wt thread is ideal for hand quilting, big stitch hand quilting and machine quilting. 12 weight thread creates a more defined and often primitive look. It's great for designs that use a longer stitch length if using a machine. When machine quilting with 12 wt thread, use 40 wt in the bobbin, increase your stitch length, lower your tension, use Topstitch size 90 needles and stitch slowly."

On my Singer 8280, the thread stitches are very loose. I've tried adjusting the tension of the upper and below thread. No change, still loose stitches. Any ideas? I wonder if I broke and...


The most common cause of this is improper threading.

1. Thread the upper thread properly with the presser foot in the UP position.

2. Make sure the bobbin is threading with the thread unspooling in the correct direction.

3. Make sure the needle and thread are suitable for the fabric in your project.

I cannot get the tension right on my 2600 Brother machine. I am stitching in the ditch with three layers of material. Can you please help?


Make sure you have the right size needle...not to small. Then do a simple seam through three layers (doesn't need to be a seam just sewing through 3 layers of scrap) using a wide zig zag stitch. Examine the stitch looking at both sides. Do they look even, identical?

Think in opposites, ie the bottom thread tension affects the stitch on the top side and the thread tension on top affects the stitch on the bottom side. If one side is loopy then the opposite side tension is too loose (or, sometimes that side's tension is too tight). Adjust until both sides are identical looking. Then try stitching in the ditch like you wanted to.

Skipping stitches and upper thread breaking on JCPenney 6600


Hello,
Here are a few things to try.

* Raise your feed dogs if your machine has this feature.

* When you start to sew a seam, hold the upper and bobbin thread tails. Hold them back and out of the way as you sew your first couple of stitches. This will keep them from getting caught in your machine.

* Your fabric may require a different needle. Generally, heavier fabrics require larger needles and thinner fabrics, smaller needles. You may also need a larger needle if you're sewing through many layers of fabric. And make sure to use a ballpoint needle for knit fabrics and a sharp needle for woven (or a universal needle for either). And make sure your needle is appropriate for the type of thread you're using.

* Adjust the pressure of your pressure foot, it may be too light for your fabric.

* If your upper thread and bobbin threads are different types, try using the same thread for both. And use a good quality, brand name thread.

* Change your needle plate. Try switching to a needle plate with a smaller hole (a straight stitch needle plate).

Important Note: If you change your needle plate, check to make sure your needle aligns perfectly with this smaller hole before starting to sew. A misaligned needle could hit the plate and break, which could be dangerous. And make sure to change your needle plate back for zigzag and other wide stitches.

I hope this helps.

QE 440 BSR sewing along fine then skips 2-3 stitches, bobbin seems to not catch the stitch.


Hello,
Here are a few things to try.

* Re-thread your needle
It may be threaded incorrectly (backwards).

* Reinsert your needle
Make sure it goes all the way into the holder and that it’s positioned correctly – usually with the flat side away from the bobbin, but consult your machine’s manual to be sure.

* Change your needle
Your needle may be blunt, bent, or otherwise damaged.

* Your fabric may require a different needle. Generally, heavier fabrics require larger needles and thinner fabrics, smaller needles. You may also need a larger needle if you’re sewing through many layers of fabric. And make sure to use a ballpoint needle for knit fabrics and a sharp needle for wovens or a universal needle for either. Make sure your needle is appropriate for the type of thread you’re using.

* Adjust the pressure of your pressure foot
It may be too light for your fabric.

* Change your thread
If your upper thread and bobbin threads are different types, try using the same thread for
both. And use a good quality, brand name thread.

* Adjust your thread tension
It may be too tight or too loose.

* Re-thread your machine
