A bobbin case is used for sewing on a sewing machine. It holds the bobbin in place so it is able to go in the sewing machine.

I'm not exactly sure what you are asking, but if it is "WHAT IS a sewing machine bobbin?" then I can help. The sewing machine bobbin is the round "wheel" like part that holds the thread under the sewing needle. In the older machines it was metal, and in the newer machines it is mainly plastic. Mostly, these bobbins are not interchangeable from one machine to the next. Each sewing machine brand requires its' own specific bobbin. Without the bobbin (with thread on it!) a machine is unable to sew.
A sewing bobbin is a small spool of thread that goes underneath the needle and sewing platform. It provides the lower thread for the sewing machine. Different models of machines use different bobbins, but most machines require you to create the bobbin yourself.If you'd like to see a picture of a typical sewing machine bobbin, visit the "related link" below.If you look at a diagram of the way a sewing machine works, you can see that when the needle goes down to the bobbin, the bobbin thread is pushed around the upper thread, and that is how the two pieces of fabric are joined together.The upper thread goes along the top of the seam, and the bobbin thread goes along the bottom of the seam.

The winder allows the machine to transfer thread from a spool onto the bobbin, which provides the underside, connecting, stitches. It does a better and more even job of it that winding the thread by hand.
Singer Corporation first sewing machine was made on 1846. The machine was called Bobbin driver or Transverse shuttle invented by Elias Howe.
It depends on the sewing machine. They often have little arrows on the bit the bobbin goes in to help. Try looking at your manual or if all else fails, try it each way and see what works!
I'm assuming you're talking about winding a bobbin on a sewing machine? If so, there is a post similar to the one for thread (near it) that you put the empty bobbin on. Then you put your spool of thread where it goes on the machine. You wind your thread from the spool of thread to the bobbin (there's usually a little chart on your machine, but if not, the thread goes through a hook or two and then you wind it about 4 times around the bobbin (clockwise). In newer machines you then push the bobbin toward a holder type thing that is near it. This disengages the needle from going up and down and lets the machine wind the thread as you push the pedal. On older machines, you have to turn the handle of the machine toward you and it disengages the needle, allowing the bobbin to be filled when you press the pedal. Hope this helps! You could probably google your sewing machine name and how to thread a bobbin and maybe get a diagram.
