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.
Every sewing machine that I have owned always had a bobbin. If I'm correct, even serger and overlock machines have bobbins. The bobbin has the thread on it that comes from underneath the fabric and connects the thread together to make the stitch with the thread that comes from the top, or from the spool of thread.

Yes, you do need the bobbin
To operate a sewing machine, you will need a place to set the machine up, thread, bobbins and a needle for your machine and fabric type.
Most sewing machines require bobbins, so you will most likely need one. Look up the specific machine to find out what size or type of bobbin is ideal.
I have a 1938 electric singer sewing machine with cabinet and seat with most of the attachments and bobbins. What is my machine worth please.
yes you can it wont effect anything
You can get bobbins from any sewing supply shop that sells sewing machines.
Since there are different adjustments for every brand of sewing machines, the best you can do is taking it to a technician who will teach you how to make bobbins. It's a very easy operation.
I use the universal needles and have for years. Works fine and I've had the machine for about 35 years
yes they did
Yes, you still need a sewing machine, as the overlock machine is designed simply to finish the edges of the fabric. Overlock machines do not go backwards, turn, zigzag, or anything stitch functions that you may need (depending on what you are sewing) You do not absolutely need a sewing machine if it's a quick and easy project (such as a repair, or a pillow), but for everyday use, you need both.
All the Emdeko machines I have seen are 15 Class oscillating shuttle models and use the 15 Class bobbins.
Most (if not all) current Kenmore machines are... Janome! Bobbins for Janome will work in Kenmore and vice-versa.
Have the instruction book but does not mention so I have the machine and I would say same size as the singer but are metal OK ( bobbin ) Most Kenmore sewing machines (including this one) take class 15 bobbins which you can find at Joann's, Walmart, and most places that deal in sewing machines. They come in either plastic or metal.
