Lower looper unthreads itself while sewing

I'll be sewing nicely for a while when all of the sudden, the fabric starts gathering and eventually the serger stops sewing. When I open it up, the thread has come out of the lower looper eye. Am I doing something wrong?

    Thank you!! I'm sorry you're having problems, but I'm glad to know it's not just me. My machine is a Janome Harmony 9102D but the lower looper is also coming un-threaded for no apparent reason...I have spent hours threading and re-threading the machine according to the diagrams in my manual, but can't seem to correct the problem. It is so weird because everything will start off fine and all of a sudden the threads stop locking and when I open the machine the lower looper thread has somehow escaped the eye of the looper--it is still correctly threaded everywhere else and the thread has not been broken (so one end is wound around the thread cone and the other is still locked up in my stitches but somehow the middle has escaped a seemingly solid metal looper--I can't understand how this is physically possible?...)

    I have the same problem - and I can see noone has a solution. How does it come out and not break?????

    I wish someone had the answer to this phenomenon! I took three sewing classes to save money on having pants taken up, and now this! I don't understand how a thread can come out of a closed hole without breaking either. Someone, please help us!

Change the needle. I know this sounds wrong but it does fix this problem.

I just got a new Janome 8002d serger. Why does it make a clicking noise when I begin to serge and then it goes to straight stitching that comes unsewn.


I don't have a Janome, but you might check your threading to see if it's correct, lucky you to get a new one!!!

I have a singer ultralock 14u34. The lower looper will not stay threaded when I try to sew, just works for an inch then nothing is catghing and the looper is no longer threaded.


Some sergers will unthread themselves if the thread is not threaded through the throat plate right. Especially the lower looper because there is not a lot of space for it to move. Try bringing the thread from the looper straight up through the hole in the throat plate, not to the side of the plate. You can also talk to the professionals at the link that I have attached. They are very helpful and easy to work with. Good luck Sewing Machine Repair Repair Sewing Machines Sewing Machines Repair Fix...

Thread broke on bottom looper the first time out of box i had to try and thread and the tension was still tight The bottom threads were not stiching


I'm going to assume here you're talking about a serger. Unthread the lower looper and the eyes of the needle. Set the lower looper tension to 0. Rethread the lower looper, then the needle eyes. Then reset the lower looper tension (try about half a number lower) and see if it chains. If it won't chain, try replacing the needles.

Upper looper hits lower looper


The upper/lower looper need realignment, requires a qualified technician to do this.

Correct settings for 804dsp serger to sew a sweater.


Are you wanting to use the serger to sew a hand knitted sweater together? or do you mean a sweat shirt knit or other knit fabric. If it is the first option, I'd say don't bother, as you can't do it with the blades working because it will cut your knitting and the wool will unravel in the seams.

If it is the second option then I would start with the following settings.

Four thread stitch, so both needles and the upper and lower loopers threaded. Set tension on all four dials to 5, stitch length to between 2 and 3, and differential on zero. Move the cutting blade over to the right for a wider seam. Now test stitch on some fabric scraps double layer and see what the seam is looking like.

Now you want to adjust a couple of things: firstly width of the seam. Is it the size you want? If you'd like it a little narrower, then adjust the cutting blade back a little to the left to narrow the seam slightly - just depends on the fabric weight. For example if it is a loose open weave like boucle you would want a wide seam to make sure it holds the fibres fully.

Now you can adjust the upper and lower loopers to get the thread wrapping around the edge looking nice. Look at the seam and the fabric inside it. Is it tunnelling and pulling up the fabric? if so, release tension on both loopers a half number to put more thread into the seam. Test stitch again and see if the loopers are meeting nicely on the cut edge of the fabric. Upper and lower looper threads should be meeting right on the cut edge so if this isn't happening and one showing on the other side, then tighten the looser one by half a number and test again.

If the threads are hanging off the edge then you have the choice of moving the blade to the right to cut less fabric off, or tightening up the looper tensions to pull in the thread.

That's it, hope this helps you to master your serger.

If you'd like some images and further explanations of other stitching you can do with your overlocker, then Debbie Coswell has some great information on line at www.sewing.about.com, just search "overlocker" to find the specific pages.


Good luck

The lower looper keeps breaking thread


Hi,...if the lower looper thread is breaking before you sew six inches or more then I suspect a threading problem.When the lower looper thread breaks, You MUST unthread the needles before you thread the lower looper. Thread the looper and then rethread the needles.

Hope that helps,
Doug

I cannot find instructions on how to gather/ruffle with my imagine wave babylock overlocker, please help.I need to know what settings and how many threads to use etc.


I do not have the Wave, but in the manual for my Imagine, on page 17, it states:

"at the maximum setting of 2.0 the differential feed can gather lightweight fabric to nearly double fullness.

To maximize the gathering effects, use the longest stitch length setting."

There is no indication as to the number of threads to use, but in the picture, it appears to be four.

I would use scraps of the same fabric to be ruffled and test this technique until I achieved the preferred look.

Lower looper


It is impossible for a looper to come unthreaded if you are holding one end and the other is still feeding off the spool. Somewhere a thread broke - must be either the upper looper or the needle. Try completely re-threading your machine. Many machines have an "order" they prefer to be threaded. Try starting from the right tension guide and work to the left.
