Singer Sewing Machine Tension

My bobbin thread tension is very loose.  I saw somewhere that I could adjust the leaf spring tension on the bobbin case?  I need to finda a tiny screwdriver before I attempt that.  I was using my sewing machine two days ago and it worked great.  I had to make the tension very loose to pull the threads to make a ruffle on a Halloween costume.  I have also changed the thickness of fabric that could of affected my problem.  And of course I can't find my manual and need to finish up my project.

This is an answer to another person with a similar complaint. Try the suggestion below, it may fix the problem.

From your description it appears that you have tried tension settings on the upper tension control adjustment knob without success.
Check that the bobin tension is adjusted correctly by taking out the bobin complete with the spool.
Pull the cotton thread and it should be a smooth light pressure if the tension is correct. If it is tight to pull or pulls freely then adjust the tension screw which is found on the outside of the bobbin. The screw is very small and requires a minature size screwdriver. The adjustment will only be a slight turn of the screw one way or the other to obtain the correct tension(depending if it was loose or tight).
Once this is set reinstall the bobin and tread up the machine, hopefully with the upper tension set at approx."2" the machine will sew correctly.

SOURCE: Difficulty adjusting tension to avoid bobbin looping

it sounds like your bobbin tension is too tight. to adjust bobbin tension, remove bobbin case (remove needle plate first) and adjust bobbin tension screw on side of case until bobbin thread has a slight resistance as you pull it through the bobbin case.

this will be trial and error until you get best result. you should always try and match top and bottom threads. if the top thread is quite thick you may have continue to increase needle thread tension until balanced.

Straight stitch. Top is fine loose on bottomadjusting top tension does not help how to adjust bottom tension?


Usually, if there are loose threads under the fabric, it is the top thread that is too loose. Check your sewing sample closely--you can even test with two different color threads to help distinguish which thread is which. Loose top thread will generally be pulled DOWN and show under the fabric. Loose bobbin thread will be pulled UP and show on the top of the fabric. The ideal tension is when both threads MEET in the middle of the fabric.

First, remove the thread from the machine. Install a brand new needle. Always Raise the Presser Foot and thread the upper thread, making certain the thread path is correct.

Check that the bobbin thread is threaded correctly and turning the proper direction in the bobbin case.

Set the upper tension to the midway point and sew a retest. A tweaking of upper tension may be necessary to get it where it should be. Generally, upper tension should make the majority of adjustments needed for tension correction. Bobbin tension is one of the last tension adjustments to make as it is very sensitive and can go awry very quickly.

If, in fact, the bobbin tension is off, the tension skrew on the bobbin case is where the adjustment is made. Before making any bobbin tension adjustments, mark where the skrew slot is located on the bobbin case with a permanent marker. This will allow you to reverse your changes if necessary. Be CAREFUL as TINY changes make HUGE differences in tension. Make only 1/8th turn adjustment, then retest before making another adjustment.

Remember that tension testing and readjustment are a necessity when sewing. The same tension that will work with light weight thread and fine fabric will most likely not work when using heavy thread on drapery fabric. Get comfortable with making tension adjustments to get the ideal tension for each project.

How to Adjust the Tension on Sewing Machine

How do I adjust tension on the bobbin?


First of all, be absolutely certain that the problems being experienced are not a result of the upper thread tension, ie threading when the presser foot is not in the up position, thread pathway is correct, a brand-new needle compatible with the thread and fabric, etc.

Before making any adjustments to the bobbin tension, be sure to mark the bobbin case where the skrew slot sets with permanent marker or a small drop of nail polish. This will allow you to reset it to original should your adjustments not be successful. And, make only minor movements of the tension adjustment, ie 1/8th of a turn, then re-test, before making another adjustment. Tiny incremental changes will make a huge difference in the outcome.

When i sew a test piece of fabric on my sewing machine to check the stitching, the top thread seems fine but the bottom thread is loose and adjusting the tension doesn't seem to help


there are two thread tensioners on a machine
the first one is on the front of the machine for the top thread
the second is the small screw that holds the small flat spring under which you pull the thread after you put the bobbin in the holder
as you put the bobbin in the holder you have to pull the thread around the side until it slips into a small slot then under a retainer spring
that spring is adjustable by that small screw
the amount of tension added or released by that screw is minute so as little as 1/8 turn has a big bearing on the amount of tension of the bobbin thread so turn it just a small bit at a time until the thread tension is correct

What adjustment do you need to make when the bobbin is throwing too much thread out.


Your tension is is too loose somewhere I guess, so will need tightening. Tighten the upper tension first to see if that helps before tackling the spring on the bobbin. If you need to tighten the spring on the bobbin then do it in tiny increments and remember where you started. Try taking out the bobbin and gently pulling by hand the thread from it; it should have a slightly tight feel on the correct tension..

The top stities is good/the bottom stities is very loose


Can be a tension problem, can be a threading problem too. First, unthread machine completely, and rethread carefully, be sure it's all just right. Check the thread guides to be sure there aren't any that are catching the thread. Also try using a new spool of thread, and a new needle as well.

If, after doing all that, you cannot find an upper tension setting that gives you a balanced stitch, on occasion, the bobbin might also need an adjustment for tension. Generally you should be able to get a balanced stitch at any setting, so if no setting is working, check bobbin tension too.

Remove the bobbin case. Pull a length of thread out from it and dangle the bobbin case by the thread and bounce it a little, as if you were playing with a YoYo. If the bobbin won't move at all, tension may be too tight. If it slides along the thread freely, it is too loose.

Get something to mark the position of the tiny screw that's on the bobbin case first and mark where it is now, so you can put it back where it was if need be. It is usually just a tiny slot screw, and you only move it a tiny, tiny fraction of a turn at one time. Clockwise usually tightens.. but check to be sure which direction does what. Then move the screw very slightly and dangle the bobbin case again to see if it's better.

Should move along the thread when you jerk the thread, but not slide freely, and not stick tightly in one place.

If adjusting the bobbin does not help, then chances are that the upper tension adjustment mechanism is worn out, and it may need to be replaced.

I have a VX1250. I don't know how to regulate the tension.


There is two places to adjust thread tension: the top tension device controls the top thread tension and is usually a dial or knob with numbers on the front of the machine.

Then there is some form of tension device on the bobbin; in your case I believe the Brother has a removable bobbin case with a tension spring which holds the bobbin thread firmly: the tension spring can be adjusted with a screwdriver but once set, you shouldn't need to adjust this much, just alter the top tension slightly for different weights of fabric. So start by setting top tension dial to 4-5 and test stitch a seam. Use different coloured but the same type of thread top and bottom and take a look at the seam. You want to see a balanced even seam.

Here is a link to a great info site for this:
http://www.sewusa.com/Sewing_Machine_Repair/Thread_Tension_Settings.htm

If the bobbin thread is too loose, then you probably will need to finess the tension spring on the bobbin case and adjust this slightly. The best way to set the tension on the bobbin case is as follows. Load the bobbin into the bobbin case and pull the thread tail into the tension spring, then suspend the bobbin by holding the thread tail up in the air (the dangle test). You want it to be just tight enough to hold its own weight, but still able to release thread when you pull gently downwards on the bobbin case. If it isn't doing this then take your little screw driver and adjust the screw on the leaf tension spring by ONE QUARTER TURN ONLY. Lefty looser, Righter Tighter. Then test again, and adjust again until its right.

Now test stitch again and finess your top tension to get the seam even. Remember to change the needle for each new sewing project too; this will impact tension also.

Top thread too loose, brings up bobbin thread. Tried to adjust, but cant get it right. Have manuel, but cannot locate it currently I have The Omega model


Hi. If the bobbin thread is coming up on top, then the upper tension is too tight. Try loosening it.

Hi. The best way to adjust your tension is to use good-quality thread, a size 12 needle, and different color threads in the bobbin and on top. That way, it's easier to see which thread is loose. Sew a few inches, check, and adjust (make sure the pressure foot is DOWN). Stitch a few more inches, recheck, and adjust some more. Just move the adjustment knob a little bit each time.

You might also want to use a bit of unwaxed dental floss and floss the tension disks. That helps get rid of any old lint and pieces of thread that build up in there.

As a last resort, you might need to adjust your bobbin tension. There is a very small screw on the bobbin case that tightens/loosens the spring/lever. If you need to adjust it, only move the screw a tiny bit. But, like I said, this is only a last resort--almost all adjustments can be done by adjusting the upper tension.

Hope this helps!

I need to know how to adjust the bobbin tension on my euro-prox sewing machine.


There is a tiny screw on the side of the bobbin case.

Mark the **** (in the screw head) position on the bobbin case with tiny dab of nail polish so you will know where the original setting was.

Left/loose and right/tight.

If you are adjusting because the bottom stitching is loose/loopy, first try threading the machine with the presser foot up to see if this solves the problem.
