SOURCE: Tension

I'm assuming the thread is looping on the bottom. If this is not the case, ignore the rest of this.
Perform a tension test. Tension assembly test. To do this test. Pull the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.)
If it doesn’t work this way then you probably have a piece of thread or lint stuck inside the tension discs. To remove it, turn the tension to 0 zero and raise the presser foot.Using a small screwdriver, open the space between the discs and spray with canned or compressed air. The stuff should come out. Do the tension test again to make sure you got everything and then try sewing again.

Bobbin Tension Adjustment:

1. Do you have a genuine Bernina bobbin casing and not an Oriental copy? If yes, proceed as follows:
2. To set the bobbin tension, wind a genuine Bernina bobbin with Metrosene thread, type 1161 white thread as your "gaging thread". Load the bobbin case so that the bobbin turns CW. Attach the bobbin case to the hook body from the machine. Wind a couple of revolutions of thread around your index finger with the assembled bobbin case and hook body dangling about 6" to 12" below your finger. Gently and rapidly move your finger back and forth in a "sideways" motion about 1/4" to create a gentle vibration on the bobbin assembly. (Do not shake the bobbin assembly up and down). When the tension is right, the bobbin assembly should fall slowly and as you stop the movement, the assembly should stop.
The adjustment is found on the small screw, holding the flat tension spring against the bobbin case. If the tension is too tight, one must loosen the screw (past) the desired location and always make the adjustment by tightening to the correct position.

There are other checks for tension imbalance and associated problems on the bobbin case that I won't go into here. For further information I can help you later on.

Top Tension Adjustment:

1. The top tension rarely changes and can be depended on throughout the life of that machine providing that tension assembly is maintained occasionally. This can be done by blowing out the tension disks with the presser bar lever in the up position. One can also drag or pull a piece of sized percale or muslin through the disks with the presser bar lever in a down position. Perhaps both methods can be employed.
2. Load the top of the machine with Metrosene 1161 thread in a dissimilar color. I prefer to use a pastel color so as not to create an optical illusion of imbalanced tension.
3. Sew a satin stitch (.25 on the Nova 900) in sized cotton muslin with a thin piece of paper between two plys of fabric. The width should not exceed 4.5mm (standard width on the 900 Nova), however the newer machines have wider stitch widths so one must adjust as specified. The result will be a slight amount of top thread in symmetric lines on both the right and left sides of the satin stitch.

Typically, the top tension will not need adjusting. If the Nova 900 needs adjustment, please ask for additional help.

Hello,
Here are several solutions to try. I realize you have tried some of these but it may be worth a second try.

* Re-thread your machine, an incorrectly threaded machine can cause thread to break.

* Decrease the tension on your machine. The tension may be too tight for your thread.

* Reposition the spool of thread on the spindle. You know that little nick in the edge of a spool that’s used to hold the loose end of the thread? Your thread may be catching on this nick as you sew. Place your spool so that this nick rests against the bottom of the spindle.

* Reinsert your needle and 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 bent or dull. The eye of your needle may have a nick in it that’s cutting the thread as you sew. Or your needle may be too small for the thread you’re using, in which case, change to a larger needle. And make sure your needle is appropriate for the weight and type of your fabric.

* Change your thread
Your thread may be weak. Or your thread may be fuzzy and irregular, causing it to catch in the
eye of your needle as you sew. Cheap thread tends to be weak and fuzzy, so make sure to
use a quality, brand name thread. And if you’ve been sewing with an older cotton thread, which
can dry out and become brittle with age, try a newer thread.

* Check your presser foot for damage to the needle hole
A burr in your presser foot’s needle hole may be cutting your thread. Gently smooth any rough
spot you find with an emery cloth.

* There may be a burr in one of your thread guides, in which case, you may need to have your
machine professionally serviced to have the part replaced.

I hope this helps.

SOURCE: The upper thread tension on my Bernina 930 is too loose

If you threaded the machine with the presser foot lever raised and the stitching is still loose, the tension control may need a new spring or the entire control may need to be replaced.

Berninas tend to be the only brand that hold their value and it would be worth the expense to take it to an authorized Bernina dealer for service and repair.

Bernina activa 130 tension loose after needle breaking into bobbin area


Is it the bobbin tension that is very loose? Try tightening it. Also check that the bobbin has been installed in the bobbin case, turning the correct direction and that the bobbin tension is threaded properly.

Bobbin Tension How and Why Tension is Adjusted

Understanding Bobbin Tension

Understanding Thread Tension Threads

If it is the upper tension that is loose and creating "thread nests" under the fabric, the machine is either misthreaded or possibly the thread is not seated completely in the tension disk.

Remove the upper thread from the machine.
ALWAYS RAISE the presser foot and rethread the upper thread from the beginning--verify the thread path is correct.
Set the upper tension to the midway point between high & low number (the factory standard--although it may need tweaking later for your particular machine).

Retest your machine. Hopefully, the issue has been resolved. If not, it may need service.

I have Bernia 180. The bottom thread is puckering. Top thread is perfect. I cannot find help in manual. Please help


Check that the bobbin is inserted turning the proper direction in the bobbin case and that the thread is threaded correctly through the tension control on the bobbin case.

Make sure the upper thread is threaded correctly. The factory standard upper tension setting is midway between high & lower number although this may need to be tweaked for your particular machine.

If the machine is still pulling the bobbin thread too tight, you can try tightening the upper thread tension. If it still isn't resolved, you may need to loosen the bobbin tension.

You might also want to check the presser foot pressure on your machine. That generally needs adjustment when changing from thicker to thinner fabric and vice versa.

There are tests to perform for testing and adjusting bobbin tension. There really aren't any "specifications" other than adjusting it until the bobbin drop test is where it is normally recommended.

I have a bernina Sport 801 and my bottom tension is off. I'm not sure how to fix this. Adjusting the tension setting doesn't seem to work.


On the bobbin casing is a screw to adjust bobbin tension when upper tension will not solve the problem. Check your manual for location of the screw.

Tension is loose underside


Loops appear on the surface (top side) of the fabric?
Reduce the tension by turning the upper tension control dial to a lower number. If the loops still appear on the surface of the fabric after you adjust the upper tension, the bobbin thread may be too loose. In this case, turn the screw clockwise, being careful not to over-tighten the screw, approximately 30-45 degrees to increase bobbin tension. After you adjust the bobbin thread, adjust the upper thread to match the bobbin thread.
Make sure you reset before your next project.

Old bernina 830 stitching problem: tight


Sounds like you need to adjust the tension. Probably a good idea to oil this older machine before you adjust. Also look for and clean out any lint or debris in bobbin case and around foot area.
