How does sewing machine needle work?

How does a sewing machine needle pick up the bobbin thread?

You should see a small loop come up through the needle plate (this is your bobbin thread), using the tip of a narrow object like a pencil or scissors, pull the loop up and then pull both threads (top and bobbin) under the foot and toward the back of the machine.

What kind of energy is a sewing machine?

The mechanical energy available at the machine can be converted into electrical energy without disturbing the regular work of the tailor and also with the minor modification in the existing machine. The energy generated from the day’s work could be stored in batteries and used in the nights or even to charge mobile.

What causes a sewing machine to not pick up the bobbin thread?

There could be several things that could cause the machine not to pick up the bobbin thread. The upper thread could be tangled. Remove the thread completely from the machine. The correct size spool cap should be used for the size of the thread spool.

Why is my thread bunching underneath?

A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.
