How to adjust tension on a baby lock BL1556

Have tried loosening and tightening the tension and it will sew correctly for a brief time then it starts acting up again, leaving knots and loops on the bottom, breaking the thread or snarling up inside the machine, have tried new better thread, redoing bobbins and actually replacing the bobbin, replacing the needles etc. it is a constant battle to get it to do any repair work....again any solutions.

On your bobbin case there should be a tiny screw to adjust the tension of the bobbin thread. loosen that screw if heavy thread, or tighten for thinner thread. Play with it and try getting the correct tension that will continue.

SOURCE: Bottom (bobbin thread) makes loops

I don't have the same brand as yours, but on my machine there is a little screw on the bobbin case that you tighten to increase the bobbin tension. If you've got one, turn it 1/8 to 1/4 turn at a time.

SOURCE: Top thread stitches correctly but bottom thread loops.

FYI---- Loops on the bottom-- problem is in the threading..
Loops on the top--- problem is with the bobbin.

SOURCE: bobbin thread keeps breaking

Could well be that the bobbin tension is too tight, you should only just be able to pull the bottom thread through with slight resistence, if it is too tight slacken the screw on the bobbin case anti clockwise about a quarter of a turn at a time and test until you get it right,

How do I adjust the bobbin tension on baby lock elure plus

The owner's manual provides instructions for adjusting the tension by manipulating the upper tension to either tighten or loosen the upper thread:

However, here is a discussion about adjusting bobbin tension:

Be very careful adjusting the bobbin tension as it is very easy to over-adjust.

Regular sewing - I cannot get the thread tension correct. The bobbin seems too lose. How do I adjust? I've tried using the adjust key but I still get loose thread and puckered fabric.

Be sure to RAISE the presser foot BEFORE threading the upper thread. Set the upper tension to the mid-point which is generally the factory setting. Test. If thread is looping or bunching under the fabric, the upper tension needs to be tightened. If there is a problem above the fabric, try loosening the upper tension.

NOTE--sometimes the stitching problem is a result of the type of fabric being sewn. Most machines have a presser foot pressure setting that can be tightened or loosened to accommodate the fabric.

The tension is correct when the two threads meet in the middle of your fabric.

How do I adjust the tension on my Singer 621B model I have had it for 20 years and the tread breaks every time I try to sew with it?

Put the top tension on 3. The bottom bobbin carrier remove. The little plate on the carrier has a screw to tighten and loosen for the bottom tension. Allow the thread to drop the carrier about two inches from your hand and move up and down lightly. The carrier should extend slightly when you do this. If it doesn't do it then loosen. If it does it too far then tighten. Make sure that your bobbin is rotating counterclockwise. The top may have to be adjusted by the fabric you are sewing but three is a good start.

Elna 664 Bottom Thread loose

Make sure bobbin is loaded correctly and unwinding in the correct direction. It does make a difference. Do a test seam. If not improvement....

Loosen top tension. Do a test seam to see if that helps. If it does, loosen some more until you have a balanced stitch.

Finally... if neither of those really help. Look on the bobbin case for the tension "spring" (it is flat) with two tiny screws. One holds it on... the other tightens or loosens tension. Tighten the tension on 1/4 turn. Do a test seam. Etc., etc., etc.

The only time one ever changes the bobbin tension is when they are either using substantially larger or substantially thinner thread.

Good luck.

Bottom thread bunching up, baby lock denim pro

bottom thread bunching up is actually the needle thread having no tension. Most likely the upper threading is wrong...

Tension settings for the babylock sewing machine

I found that the tension setting of 1 worked. The main problem was the machine had thread wound around behind the bobbin. I had to take the plates that are under the foot out, clean out the thread, oil the machine and use a spool of thread that had more weight than the little spool I was trying to use.

Bottom stitches are not tight. I am using a heavy weight thread on sailcloth

The heavy thread will always cause a problem. You need a needle with a large eye( top stitch or metallic thread needle)and you will need to tighten the upper tension considerably.
