The next step involves pulling the thread extension, while paying attention to the direction that the bobbin is turning. If the bobbin turns clockwise, you can ensure that the case is inserted correctly. Conversely, if the bobbin turns anti- clockwise, it proves that the bobbin inserted is wrong. So, you need to remove the bobbin, flip it, and then insert it back into the bobbin case.
Next, hold the bobbin case with the tension spring, which is a piece of metal with a hook at the end that is bolted to the case, facing upward. Then, you need to take the thread extension, and slide it through the slotted notch, under the tension spring, pulling down through the thread guide, which is the hooked end of the tension spring.
Lastly, while holding the bobbin case in one hand, you need to lift the latch on
the front of the bobbin case with the other hand, hold it, and insert the bobbin case into the rotary hook – the area that holds the bobbin in place.
Loading bobbins into home sewing machines
Today, home sewing machines have been transformed from the traditional manual ones to the more contemporary automatic ones. Here is how you can load the bobbin into such home sewing machines.
First, you need to raise the needle to the highest position by rotating the hand wheel towards you. Then, remove the bobbin cover plate by pushing the release button to the right. This will have the bobbin cover pop up sufficiently to allow removal of the cover.
Next, you can insert the bobbin, making sure that the bobbin rotates anticlockwise when you pull the thread (just opposite of that in the case of industrial sewing machines).
Now, you need to pull the thread through the slot, and then to the left. With a finger held gently on the top of the bobbin, you need to pull the thread until it stops in the slot. Then, you must pull about 6 inches of thread and lead it towards the back of the machine under the pressure foot. This will assure that the bobbin thread does not slip out of position.
Finally, replace the bobbin cover plate into the needle plate, and there, your machine is ready to sew!
