The bobbin winder question is a frequent one and it is very easy to solve. If you look at the shaft where the bobbin sits on the bobbin winder, you will notice that it has a slot in the middle of the shaft, an opening if you will. This is where you use a flat screw driver and open that space more to give more friction to the bobbin so it is not loose on the shaft. That slot was made for that. There are different bobbins on the market so thats why the slot is there. If it is too tight, grab a pair of pliers and close the gap. The metal of the bobbin winder on that shaft is malleable exactly for this reason. No need to put plastic bag material or anything like that. Use it as it was intended for.

Actually the thread needs to be not only started around the bobbin but also go through the slot at the end of the bobbin shaft to accomplish the same thing as the plastic bag

Yes i have found the solution if this is help to anyone, the bobbin needs to be tighter around the winder so i put a small plastic bag material on the winder where the bobbin goes and put the empty bobbin on top, wound the thread round and it started filling it up. So remember the bobbin must be firmly stuck on winder. Hope that resolves anyones problem, it did mine.

I have a Brother Exedra DB2-B737-403 industrial machine. How do I wind the bobbin?

It's an industrial machine. You use a stand-alone bobbin winder.

Look, no bobbin winder.

From my EXTENSIVE research on your behalf, it was an optional attachment.

I have my machine threaded for filling bobbin. I hit the pedal but it doesn’t fill??

Are you actually activating the bobbin winder by pushing the activator over?

When I try to fill my bobbin the thread gets all balled up on top of the bobbin instead of filling it. What should I do?

Consult your owner's manual. Chances are you may be threading the thread incorrectly. Make sure it is going through the bobbin winder tension guide before going to the bobbin winder mechanism.

If it continues, the bobbin winder may need a height adjustment. I had that issue with a machine that the case surrounding the bobbin mechanism was slightly misaligned. Once it was fixed, the bobbin winder worked perfectly.

When i turn the balance wheel or use the foot controller, the needle doesn't raise or lower. I put the bobbin winding assemby in the right position. The machine is on.

Is this a machine where you have to tightnen the clutch in the middle of the handwheel? Or is this one where the clutch disengages when you switch the bobbin winder on?

If it's of the second type, try turning the bobbin winder on again, and then off, crisply. Otherwise my best guess, barring other information, is that the lubricants have gone gummy or evaporated. Do you hear a motor hum?

My bobbin won't catch on the bobbin winder, the metal post spins but the plastic singer style bobbin won't spin with it. What's wrong?

The bobbin may be stripped, or the bobbin winder might be stripped; try it with a different bobbin, to rule out the bobbin being the issue; if that doesn't work, look closely at the bobbin winder to see if it has been damaged. You may be able to adjust it's shape with a pliers

I just bought a used juki DDL 8500 industrial sewing machine. It didn't come with manual. I also can't find a bobbin casing. I feel very foolish. There appears to have a bobbin winder on the side....

I just bought the same machine and mine came with a photocopied manual. There is indeed a bobbin winder on the side, there's a flat section on the side of the bobbin winder closest to you, if you push that forward it connects a wheel attached to a bobbin spoke, to the belt that runs between the machine and the motor. To wind the bobbin, put the bobbin on sideways onto the axis of the wheel that is on the inside of the machine, and push the bobbin winder forward.
If you're looking for where the bobbin case is located on the machine, if you look underneath the machine on the left hand side, there should be a metal belly, on the left side of the belly is an opening, and in there sits the bobbin casing.
I think you were asking for either one of these answers, I'm on here troubleshooting for my Juki DDL-8500, good luck with yours, hopefully I can find what I need to know too!

Bobbin case

Make sure there is no fabric or thread on the bobbin case shaft. Needle has to be in up position.
