Looping on the top means there is no tension on bottom. The bobbin thread generally rotates counter clockwise. The thread must get under the tension spring. The spring must be adjusted equal to the top tension. This you will have to play with to tighten or loosen as needed. When you sew in a zigzag you might want to loosen the top tension slightly. On a regular basis remove the bobbin case and clean with a qtip. On the race put one drop of sewing machine oil. Clean the bobbin case and replace.

Bobbin Tension How and Why Tension is Adjusted Understanding Bobbin Tension Understanding Thread Tension Threads Sewing Lesson 10 How to Fix Tension on Your Sewing Machine

First, take a look at page 68 in your user's manual. If you don't have it, you can download it free at the Singer Sewing machine site. You can (and periodically should) remove the face plate over the thread path for cleaning and oiling. There are probably threads wrapped around a part there, and in addition, you can take a flashlight and look to see if there might be threads underneath the bobbin winder preventing the machine from moving. More rarely (but possible) there may be threads wrapped around the gear underneath the bobbin basket (holds the bobbin case), so you ,may need to remove the base to access that part, but it's generally not a difficult process. While you are there, it's probably time to use a little sewing machine oil and lubricate the parts, as per your user's manual.

you placed the bobin upside down one side is flat the other is keyed so place the keyed side down usual fault with winders bobins are easy... read again the manual slowly

Actually, what you're seeing came from the top thread--not the bobbin. You need to tighten your upper thread tension.

What happens when you press the foot pedal? Does the light go on? Does the fabric move?

No top tension, follow manual to thread top again and make sure tension dial is set to 5 and thread is pulled between the tension discs fully.

Probably time for a trip to the shop. http://parts.singerco.com/CPpartCharts/5_59999/57825.pdf -- page down to "presser bar". It's one of those things that might be cheaper to fix at the shop than try to order parts for and do yourself. Especially if combined with a standard cleaning/oiling/adjustment (=tuneup).

here's a free manual from singer on the sewing machine, just click on the linkhttp://www.singerco.com/uploads/download/1270_57815.pdf

Something is binding up inside. Clean and check under the presser foot and bobbin area. Really examine under there... look for threads wrapped around and in between moving parts. Also check in the slot for the take up lever... sometimes threads get balled up inside there can cause problems. could also be a bent upper arm inside the machine (lets hope not) Get professional help if cleaning doesn't free it up.

Sorry, the only one I saw is the one on singerco.com costs $15 for the hard copy manual. But, it is a good investment because it will be invaluable for all of your questions.
