How a Sewing Machine Works

The sewing machine was invented in the early 1800s and has since been used to stitch together various materials. Whether you're a beginner in the world of sewing or an experienced pro, it's important to have a solid understanding of how your sewing machine operates.

In this article, we'll delve into the various mechanisms that make a sewing machine function, including the needle mechanism, bobbin and shuttle mechanism, feed-dog mechanism, and more. By understanding these components, you'll be able to troubleshoot any issues that may arise and confidently sew various materials with ease.


How does a sewing machine work?

A sewing machine has several parts that work together to create the stitch. To understand how a sewing machine works, you need to know about the different mechanisms that take place, as discussed below:

  • Needle mechanism
The needle is one of the most important parts of the sewing machine. The needle punctures the fabric, and then the thread is looped around the needle. The needle moves up and down, pulling the thread through the fabric.

Sewing machine needles come in all sorts of sizes and types. Each one is designed for a specific purpose. Inspired to Sew offers a wide selection of needles for various sewing purposes, such as quilting, embroidery, or topstitching.

Once you've chosen the correct needle, you can go ahead and thread it. To thread a needle, start by inserting the thread from the front to the rear and pulling it through the needle. Place your fabric under the presser foot and lower the presser foot and begin sewing, keeping your hands clear of the needle.

  • Bobbin and bobbin case or shuttle mechanism
This shuttle mechanism is typically used in industrial sewing machines, while a bobbincase can be found in home sewing machines available at Inspired to Sew. First, you'll need to remove the bobbin from the sewing machine, then wind thread onto an empty bobbin. Next , insert the bobbin onto the bobbin case, ensuring that the thread is wound correctly. Once the bobbin is in place, on some machines, you will need to bring the bobbin thread up before beginning stitching. Typically, top loading, or drop-in bobbins need to have the thread pulled up before starting to stitch. On most front-loading bobbin systems, you can continue sewing and the thread will automatically come up with the first stitch.

Next, you'll need to thread the needle. To do this, you'll need to raise the needle to the highest position by turning the hand wheel. Then, thread the needle through the eye of the needle or use the automatic threader and pull the thread through until it's tight. Once the needle is threaded, you can begin sewing.

  • Stitch formation
Sewing machines can create a wide variety of stitches, but they all work the same way. A needle pierces the fabric, and a thread is fed through the needle. The needle then moves up and down, forming a stitch.

You can create different stitches by changing how the needle moves and the thread you use. Some of the most common stitches include the straight stitch, zigzag stitch, and buttonhole stitch. Many modern sewing machines have a variety of stitch types programmed into the sewing machine to select from.

  • Fabric feeding

All sewing machines have a feed dog mechanism that helps to move the fabric along as you sew. This is usually a metal plate with teeth that grip the fabric and feed it through the machine.

Ensure your feed dogs are engaged prior to sewing. If your feed dogs are disengaged, or lowered, there will be no contact points to move the fabric through your machine and your machine will just stitch in place without forming any stitches. Then, select your stitch and if needed, set the stitch length and width. After that, you can start sewing.

To start sewing, you'll need to thread the needle, make sure the bobbin has thread, lower the presser foot and then press the foot pedal. The foot pedal controls the speed of the sewing machine. The harder you press the pedal, the faster the sewing machine will sew.

As you sew, the feed dogs will help to move the fabric along. You can guide the fabric with your hands, but the feed dogs will do most of the work.

Once you're done sewing, you can release the foot pedal, and the sewing machine will stop. Then, you can raise the presser foot, cut the thread and remove the fabric from the machine.
