Georgia, Generally it is one of two problems: 1. there is a thread stuck in the spindle where the metal disk attaches to the machine. If this is the problem, put a couple drops of oil on the spot and pull the thread loose. While you are there, you should be able to see a tiny hole at the top of the metal where the spindle runs between the disk and the bobbin. Put a couple drops of oil in that also. 2. Somehow the whole bobbin mechanism has slid forward and is not coming in contact with your belt when you engage your bobbin winder. To fix that, unscrew the two screws that attach the WHOLE METAL MECHANISM to the table. Shove the mechanism back towards the back of the machine, SLIGHTLY, and retighten the screws. After this, you might want to check to make sure that the tension on your bobbin isn't too tight. You only need minimal tension on it to wind a good bobbin. Good Luck.

Have you tried cleaning it? Sometimes a piece of thread or some fuzz gets in between the parts and causes friction. If you have a manual, or can get one online, you should walk through the pages on cleaning and do each and every part of the cleaning. If that doesn't work, call a professional.

If the threads on the back are loopy, you need to tighten the top tension. If you have a spare piece you may want to run some of the plastic through the machine until you get the tension correct. If the top tension is too loose, the stitching will just pull out.

Hello Daniel, I suggest you start with a new needle. Back off the needle thread tension and the bobbin thread tension to a minimum and see how it sews. If it does not ravel the thread, you can increase the tensions until you acquire the stitch you want.
