How Does Sewing Machine Work? 3 Steps

With the change of time sewing machines evolved in every way. In terms of power sources, materials for every other thing got upgrades.

But the mechanism of how it works remained unchanged. We all know how to use a sewing machine, don’t we?

But have you ever thought of how a sewing machine works? If your curious mind wants to know how a sewing machine works then this article is for you.

There are many types of sewing machines but as electronic sewing machines are used more we will talk about the electronic one.

Full detail is given below to make you understand how an electronic sewing machine works.

Setup: How Does Sewing Machine Work

First power on the machine switch. Then take a thread and place it on the spool spin. Bring the thread from the spool through the thread guide.

Make sure your Bobbin is in the right place. Add the thread with the bobbin and make sure it attaches properly to it for rewinding.

Now, look into your machine if it has any adjustment dial. Then adjust the thread tension dial the way you need.

You should know the basic things unless you cannot operate it. A guide book is always given with the machine.

So if you are a new sewer you should go through that book.

It will help you to understand how the outsiders’ parts work. And what you need to do to install the basic things.

Inside Mechanism of the Machine 

The most important parts that help the machine sew are the motor, the bobbin, the needle, and the fed.

Everything is important but these parts do the main job for stitching. But the most basic thing that helps to stitch follows some steps.

These steps are discussed below:


The machine will need two threads. These two will be running through the fabric you use.

One thread will go through the spool and another will be attached to the bobbin.

When you start stitching the needle will go up and down and your fabric will move. 


When the needle goes up and down the thread goes through the fabric. The needle starts to make loops when the fabric moves. 


Beneath the needle, there is a hook that rotates. When the needle goes down the hook takes the thread from it.

While the needle goes up the hook rotates with the thread. When the needle again goes down the hook takes the thread again.

That is how the stitches are made and the loop creates.

And there is another thread attached to the hook that helps to lock the other thread that is attached to the needle.

It is all about the mechanism. It works so fast that you cannot understand by looking.

Other Parts that Help to Stitch

The cover of the machine hides a lot of parts that you cannot see. Those play similar roles like the outside parts for stitching.

If you ever remove the cover you will see a lot of gears, belts, wires, pulleys inside that.

These are connected and help each other to perform many tasks.

If any of these stops working the whole machine will stop working.

So you have to be very careful and try not to touch these parts.

You don’t have to make any changes inside here. All of the works you need to do is outside that cover. 

This is how a normal electronic sewing machine works. There are many other types of electronic machines as well with customized stitch options.

Depending on what you want the machine works accordingly.  

How Sewing Machines do Different Stitches

There are types of Stitches a sewing machine can do. One of them is a loop stitch, one is chain stitch and another is lock stitch.

1. Loop Stitch

When you sew with your hand you do loop stitch by passing the needle and thread through two fabrics to attach them.

This loop of the needle continues until you are done stitching. But when you use a machine for doing loop stitches it is not as same as hand stitching.

In the case of machine stitching, the needle is attached to the machine and the eye of the needle is down towards the pointed end.

And when you power on your machine and start sewing the needle will go up and down putting the thread through your fabric.

The needle bar is connected with a powered motor and series of gears and cums which ensures proper moving of the parts.

The inside mechanism helps to pull the loop when the fabric passes accordingly.

It happens underneath the fabric. This is how to loop stitch works. 

2. Chain Stitch

Chain stitch is different from the loop stitch. When you do a chain stitch the fabric needs to be held down with the pressure foot.

When you start stitching, with every stitch the machine needle creates loops.

You have to make sure you set everything when you change your stitching type.

It is called a chain stitch because all the loops are held together. 

3. The Lock Stitch

No Matter what type of machine you use you will get this stitch option.

It also works like the chain stitch but the only difference is instead of chaining the bobbin adds more thread and uses it to lock the stitch in place properly.

Here the Bobbin and the hook are the main parts that help to lock stitch.

Final Words

You need to know the basic things of how a sewing machine works else you will not be able to sew with it.

But the details of everything are quite hard to understand. The advantage you get if you know every detail is you can easily find out a problem if you face any.

You can also get it fixed by yourself. Thus many have the curiosity of knowing how a sewing machine works.

Everything cannot be described in words because the process is all about the mechanism.

However, we tried to make the basic things clear above in the content.

We hope this article on how does sewing machine work will help you a lot to operate your machine properly.
