If you are getting lots of thread underneath, then the top tension is at fault, the thread is not being controlled by the top tension device. So check the tension is set to 5, and that the thread is fully into the tension discs. You need to clean the tension discs every so often too, just turn dial down to zero and rub a clean piece of fabric edge between the discs to remove any dust, or dye particles that lodge there.

Then rethread up the top and check that the top thread is in tension this time, if you lower the pressure foot the tension discs should operate so when you pull the top thread just before the needle it should feel firm/resistance.

If you still aren't getting top tension after this, then the device/spring may have broken and will need a service to fix.

I'm having trouble properly threading my Elna 1010. Could you please help? The bobbin thread keeps bunching up and breaking


bunching of thread under the material is an indication of insufficient tension of the needle thread
increase the needle tension until the threads meet at the center of the materialbeing sewn

Needle thread wrapping around bobbin case.


Hello Crystal, I also have had problems in the past with drop-in bobbins . I had to experiment with different model bobbins . The cause I found was due to the bobbin was not tall enough in the drop-in bobbin case. When sewing , the bobbin would rock in the bobbin case and the top thread would get caught on the bobbin instead of going over the top of the bobbin, causing the rats nest that you described. I would recommend finding a taller bobbin to fit in the bobbin case. There are about five different bobbins that will fit in there, but only one that will work properly. Knowing the exact model number of your machine would be a great help to finding the correct bobbin.

Brother cs-80 tension issue


Remove the thread from the machine. Install a brand new needle.

ALWAYS RAISE the presser foot and rethread the top thread. Set the upper tension to the midway point.

Insert the bobbin in the bobbin case (make sure it is turning the correct direction) and thread the bobbin tensioner. Install the bobbin case in the machine.

Insert the fabric under the presser foot. Lower the presser foot. While holding the top thread tail with your left hand, manually turn the handwheel (always toward you, never away!) one revolution until the top thread has pulled the bobbin thread up. Raise the presser foot and sweep both threads under the presser foot toward the back (you can use a stiletto, a pencil, or some other tool to sweep the threads). Lower the presser foot, gently hold both thread tails with your left hand and slowly turn the handwheel (either manually or by motor) to form a couple of stitches. Then let go of the thread tails and continue sewing.

If it continues to cause thread nests or you have other issues, then your machine may need service.

Hi. You "feel" that the machine is threaded correctly? You should probably completely pull the thread out and start over, making certain that it is threaded correctly. Once that is done, double check to make sure the thread is pulled all the way into the tension discs. Make sure also that you have lowered the presser foot. Is the bobbin inserted in it's case correctly? Every aspect is critical to proper function. You may also want to revue your manual.

I own a "Lena" machine


Hello

Make sure your feeddogs are up. That is the little jagged looking plate under the pressure foot. There should be a setting on your machine that will move it up and down.

If they are up then the bobbin is not in correctly. If it is a normal round bobbin that fits in a bobbin case, hold the bobbin in front of you so that the thread end is on top and the thread is going away from you, and slide it into the bobbin case. Feed the thread through the right openings in the bobbin case. When you pull the thread end the bobbin should turn clockwise.

Never hand-wind bobbins. Instead, use the accompanying bobbin winder which is attached to most machines,bobbin casings must be oiled regularly to prevent problems with the bobbin turning properly. The bobbin, when inserted properly into the bobbin casing, should spin counter-clockwise when thread is pulled.

Check the way your machine is threaded. Completely un-thread your sewing machine and re-thread it. Remember to always thread your machine with the presser foot up.

Check the bobbin and be sure the bobbin is threaded correctly and that the bobbin case is correctly threaded. Be sure the bobbin is in the bobbin case in the correct direction.

Always watch for bobbin wear, especially on the plastic type of bobbins. If the edges of the plastic are showing abrasions, the size of the bobbin has changed and may be the culprit. Although the size change is minute, it allows the bobbin to wobble in the case and changes the tension.

Change needle
Clean under needle plate where feed dogs are for lint
Clean bobbin area for lint or loose threads
Rethread machine top thread make sure to get every thread guide
& bobbin is threaded correctly & inserted in the bobbin case or shuttle correctly
Check tension 3 or 4 is usually good

after you try all this & it keeps jamming then it may need to be serviced

Setting bobbin case tension:
Put wound bobbin in bobbin case. Thread it in case. Hold the thread and carefully let go of the case only holding bobbin thread. The case should NOT move. Quickly let your hand drop 2-3 inches to let the bobbin case free fall for 2-3 inches, the bobbin case should move slightly then stop. It moves because it let’s a little thread off the bobbin. It should then stop .5"- 2" of thread should release. If so, your bobbin case tension is right. If it’s right then begin to look at your top thread tension. Always Always start with a properly adjusted bobbin case, then adjust your top tension accordingly.
