Excess bobbin thread under the fabric

I have a Singer CG-500/550 and have successfully sewed with it in the past. However, I am at my wits ends because the thread from the bobbin gathers underneath my fabric. I have adjusted the tension numerous times, cleaned the machine, rethreaded both the machine the bobbin multiple times. I had it working briefly but then I changed thread and it gummed up again. Plz help

I know you hate to hear this but you are probably threading it incorrectly. Make sure that the presser foot is in the up position when you thread the machine. This ensures that the tension discs are open and the thread makes it in between the disc.

I need elp with tension on singer cg550


You didn't explain the symptoms. Is the thread bunching, looping, knotting under the fabric? Is the bobbin thread rising to the top of the fabric?

If it is bunching under the fabric, it is probably what is called thread nesting or bird nesting. There are several fixes, sometimes more than one fix is required to resolve the issue.

Be sure to clean under the needle plate, around the bobbin, and the feed dogs. If the machine has instructions for oiling, follow the directions using a fresh, good quality sewing machine oil and apply only 1-2 drops each spot.

Install a brand new needle. Make sure you are using a needle compatible with the thread and fabric being used. All About Needles
Best practice is to use the same thread in both the upper and bobbin. Also, avoid old or bargain bin thread. Spend an extra couple of dollars to reduce frustration and increase success with your machine. If you wish, you may use two different colors of thread to test so you can easily determine what is happening with the tension.

Remove the thread from the machine. RAISE the presser foot and rethread from the beginning--the thread needs to be seated firmly in the tension disk. Verify that the correct thread path is followed (consult the owner's manual).

Set the upper tension to the midway point between high & low numbers (this is the factory standard and is a good place to start, but every machine is different and may need adjustment).

Confirm that the bobbin is installed in the bobbin case (turning the correct direction) and that the bobbin case is threaded properly.

Before beginning to stitch, hand rotate the handwheel one rotation and pull the bobbin thread to the top of the fabric. Then, gently hold the thread tails in the left hand and slowly begin to stitch.

Test.

If thread is bunching, looping under the fabric, the upper tension is too loose. Tighten it and retest. On most machines, the lower the tension number, the looser the tension.

If the bobbin thread is rising to the top of the fabric, the upper tension is too tight. Loosen the upper tension and retest.

Keep adjusting and testing until it is where you want it. Generally, tension is correct when both threads (upper & bobbin) meet in the middle of the fabric. FWIW, tension is static and should be tested and readjusted every time a new project is begun. The needle, thread, and fabric will affect the tension, so it is important to get comfortable adjusting the tension.

Also found the following reviews. Appears that some users have had tension issues with their CG550.

I have a singer CG 590C. It didn't come with manual. I'm just learning to sew. My bobbin was hung up with thread when I pulled on it I pull the whole bobbin casing out. How do I get it back in? Help


First thing, you should probably get a manual for your machine.

How to thread Singer CG 590

This machine is listed as a commercial grade professional sewing machine, so you are going to have some additional learning curve if you are just beginning to sew.

My singer 8602 does not pick up the thread from the bottom or the bobbin, the fabric wont move forward.


That can be one of a few things:
  1. the bobbin isn't threaded correctly,
  2. one of tension settings is way off (the bobbin has a tension setting controlled by a small screw, or
  3. the timing of the machine is off
Have you used this machine successfully in the past?

I am using an old singer sewing machine. the fabric is not moving when i sew..


Hello

Make sure your feeddogs are up. That is the little jagged looking plate under the pressure foot. There should be a setting on your machine that will move it up and down.

If they are up then the next thing I would suspect is that the bobbin is not in correctly. If it is a normal round bobbin that fits in a bobbin case, hold the bobbin in front of you so that the thread end is on top and the thread is going away from you, and slide it into the bobbin case. Feed the thread through the right openings in the bobbin case. When you pull the thread end the bobbin should turn clockwise.

The bobbin is not preforming properly. It jumps around when I sew and then on the back of the fabric there is a ton of excess thread.


Change needle
Clean under needle plate where feed dogs are for lint
Clean bobbin area for lint or loose threads
Rethread machine top thread make sure to get every thread guide
& bobbin
Check tension 3 or 4 is usually good

if the bobbin is top loading they will flop around some when the start getting close to empty
if it's a bottom loading bobbin & case then it's not inserted correctly

Your threading might be the problem, follow the advise in your manual for your fabric. or go to singerco.com & see what they advise in your model or another one for tensions on satin. You may need a walking foot to do the job, You can take a scrap piece of fabric and try using tissue paper under your fabric to stop the slippage, then tear it away. We did that when I was learning to sew, and it worked. Good luck.

I have problems with not be able to pick up the thread from the bobbin to start sewing


Make sure the needle is not bent and is installed with the flat side of the needle shaft to the back of the machine.

Thread the machine with the presser foot up, with the thread going into the needle from the front ,

Check the manual to be sure you have the bobbin inserted correctly into the bobbin case and the thread is feeding in the proper direction and through the guides on the bobbin case.

Hold onto the end of the top thread at the needle and hand walk the needle down and back up. This should bring the bobbin thread up. Take both thread ends under the presser foot and to the back of the machine.

Place a folded scrap of fabric under the presser foot, lower the presser foot and hand walk the needle down into the fabric and then use the power pedal to start sewing.

Thread jams in bobbin case


Open the bobbin area and make sure it is clean.

Change to a new needle.

Thread the machine with the presser foot up.

Make sure the bobbin thread is feeding in the correct direction from the bobbin spool and through the guide on the bobbin case.

Take hold of the end of the top thread and lower, then raise the needle to pull the bobbin thread up.

Take hold of both thead ends and pull them under the presser foot and to the back of the machine.

Place fabric under the presser foot. Lower and hand walk the first couple of stitches.

When sewing, and you need to stop to adjust the fabric, make sure the needle is down into the fabric. This will keep the stitch from malformation and causing a possible tangle.

If you need a manual, you can download one free at the Brother website.
