Check your stitch sample. The loose stitches under the fabric--are they actually top thread???? Usually,stitch problems under the fabric is a result of a top thread problem. In this case, it could be bird nesting.
Remove the top thread from the machine.
Install a brand new needle.
ALWAYS RAISE the presser foot.
Rethread from the beginning.
If the thread is bunching up, it sounds to me like the stitch isn't being formed properly. Nothing to do with the bobbin, more a case of timing.
The spike, or whatever it is on your machine, which is under the needle, must pass through the loop in the thread from the needle at exactly the right time.
When the needle reaches it's lowest point, as it starts to go upwards again,a loop is formed in the thread,next to the needle eye. This loop is what the spike must pass through in order to make the stitch.
check to make sure that the timing is correct for the loop to be made..guessing 3- 4 mm past bottom center. also the thread size can make a difference. it may be catching in the basket at the positioning finger for the basket.it must be able to slip past the finger to create a stitch. hope that helps point you in the correct direction.
I think you are saying that there is a loop showing on the bottom of the lower thread stitch. If the lower stitch looks correct and not bunching, you will need to change the tension on the upper stitch. Make sure that your threads are firmly inserted within the discs also before adjusting the tension. It doesn't take much to change the tension so take it slowly.
1. make sure your machine is threaded right.2. set the tension between 3 and 4 and play with the tension as you need it to adjust it.3. make sure the bobbin is threaded right.make sure to visit the site below; it has solutions to multiple problems and instructions how to thread the needle or bobbin. Good luck.htt://Fix Looping/Knotting Thread Fix Knotting/Bunching Thread Looping Bunching & Knotting Thread
I always adjust my overlocker stitch in several ways. I start test serging with the blade set right out to the right so that it "fills" the stitching. I'll set all the thread dials to the middle setting, ie. 5. Then I test serge, and check the stitch formation. If the needle is looping underneath, then I'll tighten it "A LITTLE". If the looper threads are lying off the cut edge of the fabric, then I'll dial both the top and bottom looper numbers up a little to make those threads tighter.
Each fabric behaves differently depending on its "hand" so the right stitch settings do vary, ie. organza is different to heavy weight cotton or denim. So if my inital setting is then "bunching" up the fabric within the stitching, I will then lower the numbers for the top and bottom looper to release the thread some. And if the fabric is very soft and light and still bunches up, then I will move the blade over to the left some, cutting a narrower edge within the overlocking so the threads lie better.
So revist the settings, check that the cones are flowing freely, thread is into the tension devices fully, then retest the stitching. If it is the top looper only that is looping off the edge, and not the bottom as well, and they are both set to the same number, then I'd be a bit suss about the tension dial.
it had nothing to do with the shuttle, it is the upper thread is not in the tensioner. lift the presser foot up and thread the machine even if you have to hold the thread on the top and pull on the bottom to make it go in the tensioner it will help, if a machine loops on the bottom it is the upper tension if it loops on the top it is the lower tension
First, make sure that the wire rack is DIRECTLY above the cones of thread (it may be backward). The thread must come straight up from the cone as it pulls off. Not coming straight up will cause a wavy stitch because of the thread dragging on one side of the cone.
Make sure that the threads are fully pulled into the tensioners, not riding on top of the discs.
Inspect the needle plate and ensure that the stitch forming pins and or fingers are intact.
