Practice adjusting the tensions by sewing on a long strip of fabric. Start sewing, and slowly turn the tension dial for one of the threads to a lower number. As you sew, examine the stitches to see the change in tension. The thread that has been adjusted will be slack or loose.
What tension should an Overlocker be?
But what if tensions are messed up? As a rule of thumb, on most sergers, you should start with all four knobs on 4, usually it’s a great starting point for a 4-thread stitching.
How do you adjust an overlock stitch?
A properly tensioned overlock stitch. If needle thread is too loose, increase the needle tension and/or decrease either or both looper tensions (Figure 2). If upper looper thread is too loose, tighten the upper looper tension and/or loosen the lower looper (Figure 3).
When should you increase thread tension?
Needle thread tension is too loose
The needle thread needs to be tightened if the stitching thread shows loops on the underside. On the other hand if the needle thread is too tight, it will pull up the bobbin thread and also show it on the topside.
Why is my Overlocker not sewing?
When you overlocker is not stitching right, it could be that the blades need changing. … If this threading is wrong, then your overlocker will not form a chain or even a stitch. After that, check your tension settings when you start threading the machine. If they are not already set to 0 do so before threading.
Why does my Overlocker keeps Unthreading?
If the tension on the top thread is too high or low the machine can often keep unthreading. Make sure the thread has the correct tension and if your stitches are loose you should probably try to tighten the thread a bit. It is probably the most common reason for the thread to jump out of the needle.
Why is my serger thread bunching up?
Your Thread Tension Is Too Tight
Make sure that you are using the same weight thread in both your bobbin and upper thread. If you don’t, your tension can be uneven and cause you to get bunched-up thread under your fabric.
Why are my serger stitches wavy?
In my experience, the dreaded wavy seam is most often a result of serging more than two layers of fabric together like when attaching cuffs, waistbands, and neckbands. In this tutorial, I’m serging four layers of a thick double knit fabric together. For this tutorial, I’ll be demonstrating on my Brother 1034D.
What does an Overlock stitch look like?
The overlock stitch is a combination of a straight stitch and a zigzag. It sews backwards and forwards in a straight line, but between every set of straight stitches, it sews a zigzag. If done correctly, this resembles serging, which is how most store-bought clothes are sewn.

How do you fix thread tension?
If the tension isn’t perfect, fix it by adjusting the bobbin spring; tighter if the bobbin thread shows on the upper layer, and looser if the needle thread shows on the underlayer. Make another test seam, and examine the stitches, repeating until the stitch is balanced.
Why is the stitching loose underneath?
Another reason you may experience loose stitches is that the thread tension may be low and may not be tight enough to hold these threads tighter to the fabric. When you experience loose thread, you should readjust your tension to see if it is close enough to stop the loose stitches.
How do you fix bobbin tension?
