I have a bernette 80e. I was sewing on Nylon Chiffon and needed my tension at ''1'' Now I am sewing on cotton and have my tension at ''4'' and my top is to tight and my bottom is to loose. I have tightened the screws below. I can't figure out how to fix the tension since the top and bottom thread are having problems. HELP

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)
Also look at:
Thread test
Test your thread quality to start, thread your machine and LIFT the presser foot (this opens the tension disks). Pull your top thread straight back. If you feel no tension no mater how much thread you pull, your thread is good. If that your machine passes that test, then let me know, we can go to step 2. If not, try different spool of thread, same test until you get a smooth pull (tip: always check your thread this way when you thread your machine)
Step 2:
Pull on your threaded bobbin thread while it’s in the machine. Does it pull smooth and even? If so, go to step 3. If not, try a new bobbin (bobbins get bent or distorted if wound too tight).
Clean thoroughly in the hook and bobbin case area and oil 1-2 drop is all.

The tensions must match ie. top tension =bottom tension. If the material is not sewn together tightly, that means the tensions are mismatched. Sewing machines will sew whenever the top and bottom tensions are equal (be it very tight or very loose).

We usually advise the customer to not touch the bobbin case tension. When that is not changed, all tension adjustments can be made from the top tension above the needle.

It appears that one of the two tensions (top or bottom) is much tighter then the other. I would reset the tensions to how they came, if you are unfamiliar with sewing machines this may take a little bit of experimenting until you get it back to a standard quality stitch.

The other option would be bring it to a sewing tech. A good mechanic should be able to adjust the machine and your tensions to your fabric (and recommend needle size for your thread/materials) in about an hour.

SOURCE: Upper thread wraps around bobbin mechanism, while sewing

IT PROBABLY IS THREADED INCORRECTLY. GO SLOWLY BY THE DIAPHRAGM AND MAKE SURE IT IS THREADED CORRECTLY. ALSO MAKE SURE SPOOL PIN HOLDERS ARE IN PLACE THAT HELPS TO GUIDE THE THREAD CORRECTLY.

If you have pattern dials set correctly then I might guess that one or more sets may have been missed when the thread was being set up in the machine. most of these models show either arrows or numbers for each or way the thread needs to be routed.

How do you adjust the bobbin tension?


Factory standard tension for upper thread is the midway point between the high and low number. However, that tension dial is meant to be used for tweaking tension. Generally, tweaking is required whenever the type of fabric, needle, or thread are changed, ie thicker fabric like denim should have a different upper tension setting than fine chiffon. To be successful with tension settings, one must become comfortable adjusting the upper tension.

NOTE: Accurate tension is achieved when the upper thread and bobbin thread meet in the middle of the fabric.

I can't get the tension right. The stitches on the top side are too loose and the thread just pulls out.


loosen the needle thread tension of a bit
sew on a scrap bit of material until you get the tensions right
correct tension is when the bottom thread and the top thread meet at the join of the two pieces being sewn
you will only need to sew 1" to see how it is going

How to set bottom and top thread center of material


Hello
It sounds like you are trying to balance the top and bobbin thread so it locks perfectly. If so, this is accomplished by balancing the thread "tension". If you see loops on the underside of the fabric, tighten (increase) the tension. If loops for on the top, lower the tension.

If the fabric is puckering: reduce the stitch length AND you may need to use a finer needle along with finer thread in the bobbin and on top.

Presser foot pressure is rarely adjusted, unless sewing with extremely variable fabrics. For example, pressure is lowered when sewing with silk chiffon as it transports easily under the presser foot (and to prevent damage to the fragile fabric). Whereas pressure is increased when sewing with tent canvass to allow the feed dogs to be able to 'grip' and move the fabric.

Happy Sewing!

My Bernina Bernette 65 has a problem with the thread bunching up every 10-15 stiches on the bottom. Some of the thread stitches on the bottom of the fabric are in a straight line, and then the thread will...


try a new needle--one that is for the fabric being sewed
then try to adjust the top thread tension again, if the stitches remain loose and the tension won't adjust then the tension knob needs to be checked to see if there is something wrong with it.
also check to make sure the bobbin is inserted correctly into the bobbin case, if the bobbin is not turned the right way in the bobbin case the sewing machine will not stitch correctly.

The thread underneath when sewing is too loosed


Usually thread too loose on the bottom is caused by the upper tension being too loose. The top and bottom tensions work together with the top thread making the underside of the stitch seem too taunt or too loose and the bobbin thread causing the top side of the stitch to be loopy or too tight. Select a large zig zag stick and sew a couple of inches. Then examine the stitch. It should look identical on both sides. Look to see which side is drawn too tight, the zig zag being smaller on that side with threads from the bottom threads pulled through. Then adjust the two tensions so that they make a uniform, identical stitch.

Also, when the bobbin tension is right you can hold the bobbin dangling by the thread and it won't spool out to the floor but will let loose a bit with a slight flick of the wrist. Too loose it will just spool out. Too tight and it won't drop at all. When you get that set right then do the above zig zag test to see where the top tension should be set.

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.

Loose stitch


Welcome to FixYa. I am the sewing machine expert that chose your issue to solve.

When everything seems to be working fine and an occasional stitch is loose.....now get ready.......here it is.......the needle!

It seems impossible, but the needle is the most neglected part of the machine. The one you are using could be slightly bent or have a slight burr that you won't see with the naked eye. Also, needles, especially in an embroidery machine (which work their buns off), are only good for about 8 hours of cumulative use. I would say that an embroidery needle should be retired after 3 or 4. They get dull like a razor blade which can cause enough drag to create a timing issue that's barely perceptible.
Welcome to FixYa! I am the sewing machine expert that chose to help you with your issue.

There are really only two things that can cause bottom (note: remember that problems with the bottom thread, almost always comes from the top and not the bobbin. Bobbins rarely need tension adjustments). These two things are:
  1. An area was missed when the machine was threaded (most machines have an arrow at each area on the thread path where the thread MUST run or the stitch on the bottom will be sloppy. Threading can be tricky and even the most experienced miss once in a while.
  2. The tension adjustment mechanism in the thread path. If the thread is not properly through this area, the thread on the bottom will be sloppy or if, threaded properly, and the tension is set too loose, the stitch will be sloppy. If the tension is set too tight, the bottom thread will be tight and pucker the fabric.
It is counter-intuitive that problems with the top tension cause problems with the bottom stitch but it sure will.

So try it and see if that helps.

Top color thread showing on bottom of embroidery on a Bernina Deco 330 embroidery machine


Upper tension is too loose or lower tension is too tight.This might be a good thing. It depends upon how much it is pulling the thread under. A perfect tension on embroidery is about 2/3's lower thread and 1/3 upper thread showing on the bottom.

Bobbin on a Viking #1+ sewing machine


Could be the bobbin case tension is too tight--are you using a thicker thread than usual? Also, check to make sure that it is the correct bobbin for your machine--several are very similar but if not exact, will not sew properly. Also, if the thread is not evenly wound on the bobbin, there would be problems. Check to make sure the bobbin thread is threaded through the bobbin tension. It may help to tighten the top tension, but if the bobbin case tension is too tight, adjusting the top tension will not completely resolve the problem. The tension is correct when the top and bobbin threads meet in the middle of the fabric--this means that whenever you start a different project, you may need to re-adjust the tension.
