Thread loops I have a Consew 206RB-1. I have re-thread it a million times. Adjusted the tension. Changed the needle. The top thread keeps looping on the bottom. When I start to sew, it starts looping, then it will sew fine for a while then it starts up againg. I am not sure what to do next. Any ideas? Thank You Janet

If the thread is looping under the fabric, it is a top tension issue.

Make sure you are using a new needle and that the needle/thread/fabric are compatible.

Verify it is threaded correctly and that the thread is firmly seated in the tension disks.

If the top thread is still looping under the fabric, then the upper tension is too loose.

...

I am not sure about this particular machine but in most machines there will be a nob on the front loose low numbers like 0 1 -2 work well on number 3. If the nob is not on the front check and see if it is on the side.

the needle thread should form the loop which is grabbed by the hook. before getting too involved with timing etc, clean bobbin area a fit a new needle

The top thread breaks
1. the needle thread is not threaded properly
2. The needle thread tension is to tight
3. The needle is bent or blunt
4. The needle is incorrectly inserted
5. The needle thread & the bobbin thread are not set under the presser foot when starting to sew
6. the threads were not drawn to the rear after sewing
7. The thread is either to heavy or to fine for the needle
8. Try a different spool or cone of thread



Thread looping on the bottom of your fabric can be caused by little or no top tension or too much bobbin tension. Another cause is thread or lint caught in the top tension.Make sure the thread is between the tension discs and that no thread or lint is caught

It's most likely not the machine. It's the other things, ie needle, thread, etc. combination. For sewing knit, be sure to use a ball point needle. The needle eye size is important to so the thread is neither too small nor too large for the thread weight.

FWIW, it sounds like bird nesting. --the thread is not seated completely in the tension disk. Remove the top thread from the machine and ALWAYS RAISE the presser foot when rethreading!

Also, check that the tension is appropriate for the project. The two threads should meet in the middle of the fabric. If there is top thread showing on the underside of the fabric, the top tension is too loose. Tighten it until it until the top thread pulls the bobbin thread up into the fabric.

Top thread snapping. Do you have an idea of there it is breaking?

First I would check the needle throat plate and needle. If you have stab marks on your needle plate, examine it closely for a crack. (get out the magnifying glass or jewelers loop) I recently fixed a problem I had with an old singer that kept breaking the top thread by replacing the needle plate. The old needle plate was so damaged it had actually made a knife edge which consistently cut the thread right at that location.

Change your needle and make sure it is the proper size for your thread. Too narrow of an eye can shred the thread causing it to break.

Next, check anything along your threading process that could be catching or snagging the thread. A worn or chipped thread guide can be a real problem.

Also make sure your thread hasn't dropped down below your thread cones and wrapped around the thread spindle. This would cause extra tension that might not be readily apparent.

Good luck

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.

Thank you and good luck.

Have you checked to see if the needle and thread are compatible? I use several different sized needles on my machine, depending on the thread and fabric I'm sewing.

Possibly, your machine might need lubrication or service.

Good luck!

Try this. reomove thread and bobbin from machine.. Set thread tension to the middle number. Rethread machine carefully making sure the thread is thru the tension wheel. Replace bobbin making sure that thread is thru it's tensioner.
Rule of thumb. Loops on the bottom, problem is on the top. Loops on the top, problem is with the bobbin.
