CONSEW 206RB5 TOP THREAD NOT FORMING STITCHES AND BREAKING

Is the thread breaking? Most sewing machine issues are caused by incorrect threading or incorrect bobbin tension and upper thread tension. Another reason could be that the bobbin carrier and shuttle are not properly latched in.

Or the machine just needs servicing and the timing done.

Your tension is too tight. Increase the tension to a higher number, then check the stitch with a scrap piece of material to see what the stitch looks like. Also your thread makes a difference.different treads on bottom and on top will make you stitches abnormal.

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.

Sewing Machine Thread Bunching Up Here Why

Birds nest under the fabric big loops of thread top side looks good...

Re-check the thread that is knotted. It's most likely the top thread causing what is called thread nesting or what I term "thread barfs."

Thread problems appearing on the top of the fabric are generally caused by the bobbin thread. Problems appearing under the fabric are usually a result of upper thread issues.

Remove the top thread.
ALWAYS RAISE the presser foot and rethread from the beginning.
Verify the thread path is correct.
Set the upper tension to the midway point.

Be sure you are using a brand new needle.

Remove the thread from the machine.

ALWAYS RAISE THE PRESSER FOOT and rethread the upper thread from the beginning. Make sure the thread path is correct.

Verify the bobbin is installed and turning the correct direction in the bobbin case and that the bobbin thread is threaded through the bobbin tension mechanism.

Set the upper tension to the midway point between high & low number--this may require some adjustment for your particular machine.

Pull the bobbin thread to the top of your sewing project before beginning to stitch.
How and Why to Bring up the Bobbin Thread

Re-test your machine on a scrap quilt sandwich (make sure the walking foot is installed correctly and that the presser foot is lowered when beginning to stitch).

Consult the owner's manual for instructions for presser foot pressure. The pressure may need to be adjusted because you are dealing with a sandwich that is thicker than regular fabric.

You may also try changing the type and size sewing machine needle you are using. Using a Top Stitch or Microtext needle will help the needle to penetrate the fabric sandwich easier. A Top Stitch needle has a larger groove to protect the thread as it pierces the fabric which helps prevent looping.

Also, verify the thread is not too small for the needle's eye.

I would ease up on the pressure, and use a teflon foot or a walking (or even feed, same thing) to sew it.

Mmmm Are you using the right stitch? Like zig zag or straight stitch only with a medium stitch length? Check that and test again.

Good day!

Good day!

A sewing machine operator can often help themselves when their machine does not operate properly.
Here are some simple instructions, which if properly used can save time and mechanics service calls.
TROUBLE;UPPER THREAD KEEPS BREAKING;
This could be trouble;================Do this;
1.Top tension to tight================loosen tension 1 turn
2.Machine improperly threaded=========check threading
3.Thread twisted on guide post========"
4.Thread twisted out of tension======="
5.Take up spring bent or broken=======Check action of spring
6.Thread jumped off pull off finger===Check threading
7.Needle bent or burred===============new needle
8.Bad cone of thread==================try another cone
TROUBLE;LOWER THREAD KEEPS BREAKING;
1.Bobbin tensionspring to tight=======Loosen tension slightly
2.Bobbin threaded wrong===============check threading
3.Bobbin wound to tight or uneven=====try new bobbin
4.lint or thread on bobbin case=======clean inside case
5.Lint or thread inside hook==========clean inside hook
6.Bobbin case nicked bent or burred===check/change case
TROUBLE;MACHINE STARTED SKIPPING STITCHES;
1.Needle bent or burred===============change
2.Needle set in crooked===============Check
3.Thread jumped off take up spring====check threading
4.Thread jumped off pull off finger===check threading
TROUBLE STITCHES SHOWING LOOPS;
1.Forming loops on top of cloth=======Tighten bobbin tension
======================================or loosen top tension.
2.forming loops on bottom of cloth====Tighten top tension
3.Bobbin placed in case incorrectly===remove and replace
4.Bobbin thread slipped from under====check threading of
tension===============================bobbin case
5.Lint or thread in top tension=======clean between tension discs


Thank you and good luck.

You can find a visual guide on the proper threading of your machine at http://www.sewusa.com/Threading_Diagrams/Threading_Pages/Consew_Sewing_Machine_Threading/consew_210_220_threading_diagram.htm. What other adjustments are you thinking of? If you have loose thread on the top or bottom, you would need to adjust the tension. The best way to do that is to start by having a different color thread in the top and in the bobbin. Then this little lesson on tension works the same with any machine.
Thread your machine with the presser foot UP. The disks that control the tension (threadgoes through them) are tightened up if the foot is down. Change the machine tension with the presser foot DOWN.Because the disks won't be engaged (see above) if the foot is up, the diskswon't move. Start at the middle setting, 3. Go up to tighten, decrease toloosen. Each machine is different, even 2 different machines of the same model.The best thing to do is start at 3 and use a different color in the top andbobbin thread so you can easily see what changes to the tension do to yourstitches. Now use a straight stitch a sew 3 or so inches. Take a lookat the top and bottom of the fabric. You don't want to see any (or at least notmuch) of the other color showing from the other side. Loops on the bottom of the fabric means you need to tighten(increase) your top tension. If you're stitches on the bottom are causingpuckering, then you need to loosen you're top tension. For the most part, youreally don't want to touch your bobbin tension-leave that to a repairtechnician. The factory setting shouldn't be touched except by someone whoreally knows what they're doing. Keep sewing a few inches at a time until you have the resultsyou want. Now you're tension is where you need it!

Might be that you need to lower the tensions quite a bit, you'll have to juggle with top and bottom tensions though, and experiment for just this operation with the Sensormatic.
