Babylock sewing machine, upper thread is bunching

Any stitch I use, the upper thread is pulling through all loose and bunched underneath where the bobbin thread should be. I've already tried replacing the bobbin casing, cleaning the machine, rethreading, changing the needle, etc

I do a lot of hemming on my machine, the underneath stitch is real real loose, I tried adjusting stuff, still is so loose I have to cut it and begin again, thanks


Is your top thread not pulling the bobbin thread up? This would be top tension too loose. FYI--be sure to ALWAYS RAISE the presser foot when threading the upper thread so it will seat properly in the tension disks.

If the bobbin thread is loose, then the bobbin tension may need to be tightened.

Top thread too tight. Bobbin thread too loose. Bobbin thread bunches up underneath material. The feeder teeth can not feed material through


first thing first - thread inside bobbin should be tightly wound in. Insert bobbin into bobbin case and thread through slot and under the spring. Spring has small screw which regulates the tension. Hold the thread like yo-yo and jerk a little down-up. It should drop just a little (not run down) - that is usually required bottom thread tension,
if not, regulate with the screw. Set top thread tension 3 and sew. If still looping under, increase the top tension higher till the looping disappears. .

Thread bunches under fabric for the first few stitches, then it sews fine.

When sewing the bobber thread bunches up underneath, and breaks off. I have tried djusting the bobber tension screw, and upper needle tension to no avail. How often should I oil this machine?


1. Your bobbin should have one drop of oil on the race (little area that the bobbin rides on) around two bobbins that you have emptied.
2. The top tension is way too loose. When you put the pressure foot down pull the thread (top) to see if there is tension. Start at four is a rule of thumb.
3. I have included some rules to follow when you are setting tension.

STRING IS BUNCHING UP. NOT FEEDING RIGHT MAYBE


By string, I assume you meant thread ? Is it bunching up underneath the fabric you are sewing, or on top ?

If it bunches up underneath the fabric, the upper thread tension may not be right or the mechanism may be worn or need replacing. If it bunches up on top, thread guides may be catching or the needle may be damaged.

First thing, try a new needle. Damaged or dull needles can cause problems. Also try a new spool of thread, because sometimes a thread spool might have been damaged or is just bad quality. Some machines will not work well with very cheap, economy threads, so if you're using cheap thread, get better thread to try also.

Test stitch after each change you make to see if it's helped. The upper thread tension adjustment should work at any setting, but for normal sewing, should be at a middle setting.

If thread snarls up on top of the fabric, unthread the machine and check every thread guide for wear or nicks that might be catching thread.. needles can cause this also. May need to replace a guide if it's damaged, or perhaps use a file, emery cloth or sandpaper to smooth a rough spot. Rethread the machine with a new spool, set the upper tension to a medium level and try again.

If the thread bunches under the fabric, it's often the upper tension that's not right. Thorough cleaning of lint from the bobbin area should be done also, even a tiny bit of lint can be a problem in some machines. Try rethreading, try a new spool of thread, and a new needle.

If no setting on the upper tension produces a balanced, even stitch without bunching, the mechanism of the tension adjuster may be worn and need either professional adjustment or replacement.

Very rarely, you may find the bobbin tension might also need adjusting. Take out the bobbin case, you'll see the tension is controlled by a small spring which has a tiny slot screw on it. Mark the exact orientation of the screw slot now, [ marker pen or tape] so you can put it back where it was if need be. If you have to to a adjust it, you should move that screw only a tiny fraction of a turn at a time.

Check bobbin tension - pull out a foot of thread and hold the end of it , with the bobbin case dangling. Shake the case up/down like a child's toy YO YO. If the bobbin moves along in reasonably even increments with each jerk, it's likely ok. Or you can pull it along and see how hard it is to pull. If the bobbin case won't move or is hard to slide, it is too tight. If it slides on the thread freely it is too loose.

Usually. clockwise turns tightens the tension, but check to be sure. One tiny adjustment at a time, it gets a bit tedious. You have to put the bobbin back in and try a few stitches after each adjustment to see if the bunching is getting any better. If it makes no change or makes it worse, put the screw back to the original position.

If you are handy and can find a repair manual for the machine, you may be able to adjust the upper tension mechanism yourself, it should not need special tools. Often for older machines the hardest part is finding another part to replace the damaged one.
