Ok, please don't take this the wrong way, but I only mention it because this happened to me: are you sure you're threading the machine correctly? I've had mine for two years and finally realized the other day that I was passing the thread behind the tension disk when it should have been in FRONT of the tension disk. I didn't have tension problems all the time when it was misthreaded, which is why I guess I never realized I was doing it incorrectly. One other possibility: if the thread spool is vertical, trying standing it up (you may need to rig something with a coffee cup and some safety pins taped to the machine, but most machines provide both vertical and horizontal spool capabilities); if it's horizontal, try moving it to a vertical position. Some threads don't care which direction they are; others are VERY finicky about this.

I am a new sewer have a Brither BM-2600 what numbers on the dial do I have for just plain stitching I have tried lots of combinations but the cotton underneath is all bunching up and not sewing right


I am not sure as to your machine, are you saying a "brother" machine? If your tension is set, say on 6 and it is too tight, turn the dial one more number......to a 7 or to a five and then check again. Also, I would rethread the machine and also take the bobbin out and then put it back into the machine. A lot of times, the bobbin isn't threaded into the machine correctly and it bunches up. Also, you can't use certain thick thread on some machines.

What is the proper tension number for a normal straight seam


Usually, the midway point of the upper tension dial is the standard factory setting. However, machines change with age and use. The correct tension is when the top and bobbin threads meet in the middle of the fabric. (However, that means you should test/reset the tension whenever you change projects because different fabrics may require a different tension setting.) Don't be afraid to adjust the top tension. You know where it started, so if you turn the wrong way, you can always undo it.

Adjusting the bobbin tension is usually a last attempt as it is very sensitive and is difficult to undo. Bobbin tension very seldom requires adjustment.

HINT: When threading the top thread, ALWAYS RAISE the presser foot and rethread from the beginning. Install a brand new needle when beginning a new project, after 8 hours of sewing, or if the needle strikes something on the machine. (A new needle is very inexpensive when compared to frustration, damaged fabric, or machine repair expenses.)

Back side of stitches are loose


increase the thread tension of the needle thread
this is an indication that the tension is not enough to pull the bobbin thread up tight

Top thread leaving loops on the bottom of the fabric.


what you describe is an indication of the needle top thread tension being too loose
make sure that the thread is between the pressure plates of the tensioner and not behind it
next remove the plates around the base at the bit the moves the material through so that you can see when the needle is approaching the bobbin hook
when the needle is at the bottom of the movement, that bobbin hook should be almost at the eye of the needle .
that is called needle position timing
if the hook is not near the eye of the needle or past it then you will have to have the machine serviced and that timing corrected
check the way the need is installed
the cut away bit should be facing the hook and the small groove is where the thread sits so that it does not jam as it goes through the material

How do I adjust tension on a Necchi Lydia 510 sewing machine?


loops under fabric means top tension needs to be tightened
try cleaning the top tension dial with some unwaxed dental floss and see if that helps. if it doesn't then the tension dial may need to be replaced
also check to make sure the spool of thread is not getting caught on the spool holder
also try a new needle--one that is correct for the fabric being sewed

How do I fix the bottom bobbin thread


THE BOTTOM AND TOP THREADS ARE IN A TUG OF WAR. WHEN THE TOP IS TOO LOOSE THE BOBBIN WILL BE PULLING HARDER THAN THE TOP THREAD SO A GREAT DEAL MORE THREAD WILL END UP ON THE BOTTOM. TO CORRECT THIS YOU INCREASE THE TOP THREAD TENSION. IF THE TOP THREAD IS PULLING HARDER THAN THE BOTTOM THEN A GREAT DEAL MORE BOBBIN THREAD WILL END UP ON THE TOP. TO CORRECT THIS YOU WOULD LOWER THE TENSION ON TOP.

My Janome Sewist 500 is making me crazy. The tension is loose on top, causing loops on the back, and the bobbin thread is just a straight line. I have changed the needle, changed the thread, rethreaded...


that sounds like the top tension dial is not working, causing looping on the underside so start by cleaning out the top tension device. To do this, unthread, turn tension to zero, then "Floss" between the discs with the selvage edge of a clean piece of waste fabric. If some black gunk comes out onto the fabric, then refloss on a fresh edge until its clean.

Then reset tension to 4 or 5 and thread up again until just before the needle. Now lower the pressure foot to engage the tension device and pull the top thread downwards - it should feel firm. If this is not happening, then I'd go the serviceman next. These things have a spring in and it may have broken.

I think the bobbin tension is probably okay so just reset that back to what it was, the straight line on the bottom is because the top thread is not being drawn back up by the take up lever on the upwards stroke due to insufficient tension on the top thread.

Hopefully cleaning the tensioner works though. Good luck.

The top stitch is perfect but underneath the material there are many loops. I am assuming this is from the bobbin. How do I correct this?


no, more likely your top tension is too loose causing the loops on the underside of your fabric, loops on top would be bobbin too loose. raise presser foot and rethread top thdead pulling thread into tension fully. set top tension dial to 5 and test sew. if still looping underneath try tightening top tension by turning dial up to 6. but usually top tension should only need minor adjustment tweeks. you can test top tension by lowering pressure foot to engage tension and holding thread just above needle thread guide, pulling thread downwards . there should be resistence on it to your pull. if you cant feel any then tension device may be faulty, and require service.
