Loopy stitches on the back

My serger was working fine and now it looks like the 3rd and 4th threads are off. I have rethreaded, played with the tension and cannot come up with a solution. Help!

    before aasuming which threads are the culprit, can you describe what looks bad on the stitch. Front? Back? Straight stitch part? ties on the edge of the stitch?

I have no real solution for your serger, but keep in mind that stitches on the bottom of the work reflect upper thread tension problem, while top stitches are a problem of the bobbin tension( FOR THE MOST PART)

What causes loose, loopy-looking stiching on the underside of the fabric?


Rethread the machine. Its almost always caused by poor quality threads or misthreading.

Over locker loopy bottom stitch


Loopy on bottom means the top tensions need to be adjusted. "All on 3 means nothing" These are tension knobs and are not required to be on the same number.

In the mean time rethread the machine with a different color on each spool This will help you determine which thread is the offender. sew the same type of material this thread set up... tighten the corresponding tension dial. Once you get a good stitch, Lift the food, cut all the threads near the spools and tie off new thread/spools and pull the thread through to the needle. Once it is all threaded again test your stitch with the same fabric again.

I just changed my Kenmore serger's needle and it stopped making the overlock stitch. I rethreaded the machine twice and make sure the position of the needles is correct but it didn't help


Hi

If you have the operators manual for this serger, you should be able to follow the threading from the start successfully. Some machines have a better threading diagram on the machine itself.

The needles should have the groove facing the operator's position. They should also be fully inserted in their mounts. Most sergers do not release the thread tensions when the presser foot is raised, therefore, you must zero the tensions to make sure the threads are fully entered into the tensioners when threading anew. After threading, you must readjust your thread tensions to the desired tensions for the set-up you plan to use. Thread tensions should be recorded for each stitch set-up because each serger tends to be a bit different, and therefore, allows you to quickly adjust for the desired stitch needed. The different stitches are adjust and fine tuned by each individual thread tension.

Hope this helps

My serger, Babylock Imagine's looper threads are too tight. I have tried rethreading, adjusting the fine tuning screw and varying stitch lengths and widths. At the recommended setting for the 3 thread...


I am having this same problem today. The needle threads when pressed look almost like a flatlock stitch. There seems to be no tension. With BabyLock's auto tension system, I have no idea what to do. I've been on the phone with my dealer about this today and he is clueless as to what may be causing it. I guess it's time for a checkup.

Loose, loopy, understitching.


Generally caused by lack of tension on the upper thread. Thread machine normally and pull the needle thread sideways from the needle with the presser foot up. It should pull smoothly. Lower the presser foot and it should become hard to pull and the needle will bend. If this doesn't happen, the upper thread is not in the tension assembly and you should rethread properly. Also, make sure thread is in the take up lever that moves up and down on the front of the machine while sewing.

Top stitch looks good, bottom stitch is loopy


this is a common problem, don't worry it's easy to fix.  take the spool of thread off, remove the bobbin.  look for any stray thread pieces in or around the bobbin case, rethread the top of the machine and when you do, follow the threading guide precisely and ---here's the trick---make certain that the thread goes between the tension discs.

I have a Singer Inspiration 4220 Sewing Machine. I was working on a quilting project last night, and everything was going fine, until I noticed that the thread on the underside of the fabric was very loose...


It's possible that there is foreign debris in the top tension assembly ,thread the machine and lower the presser foot and ensure that there is tension on the top thread

2nd needle/4th thread - threading confusion


With some sergers, but not many (singer 14u64 comes to mind), the top of the stitch will be an overedge that mates with the right needle thread, and the left needle thread will appear as a separate straight stitch. When you look at the underside of the stitch, the overedge will go all the way over to the left needle (the full width of the stitch). This is normal if you have this type of machine. Another stitch some sergers do (2/4 thread sergers) is a 2 thread chain thal looks like a lone straight stitch on both sides, and a 2 thread separate overedge.

As far as the threading of the takeup, it totally depends on your model. Always post your model number when you have questions as sergers vary greatly in design.
