Sewing Machine Parts Explained With Their Functions

Some main sewing machine parts definitions and sewing machine parts and their functions have been listed below:

1- Needle: Fabric Stitching

The needle in a sewing machine goes into the fabric and makes stitches. The needle is kept in a steady position with the help of a needle bar. Along with the feed dog and spool holder, the needle works with another thread to create perfect stitches.

2- Bobbin: Thread Holder

The bobbin is the low spool that teams up with the needle to form stitches. Held in the bobbin case, it provides tension for the lower thread. As the needle thread wraps around it, the bobbin supplies the bottom thread, creating flawless stitches.

3- Feed Dogs: Fabric Movement

The feed dog is your sewing sidekick, guiding the fabric beneath the needle for continuous stitching. As a toothed metal piece, it smoothly moves up and down, ensuring a flawless sewing journey by connecting the bobbin and spool threads.

4- Presser Foot: Fabric Stabilizer

The presser foot is a sewing superhero, keeping fabric in check and preventing wrinkles for a smooth stitch. When lowered, it holds the fabric in place with the slide plate, ensuring a precise sewing process. This essential part moves with the feed dog, applying pressure to guide the fabric through the machine evenly.

5- Spool Holder: Thread Supply

The spool in a sewing machine holds the thread, ensuring a smooth flow during sewing. The spool holder, whether horizontal or vertical, controls the thread’s direction, aiding precise stitching. The spool pin, whether vertical or horizontal, secures the spool while guiding the thread through the machine.

6- Foot Pedal: Speed Control

The foot pedal is your sewing speed maestro press more for faster sewing. This part, operated by foot, keeps the sewing process balanced. Known as foot control, it regulates machine speed and stitching. Switch it on, press the pedal, and control both stitching and finish.

7- Hand Wheel: Manual Control

The hand wheel, which is a huge knob on the right side of your machine, lets you manually raise and lower the needle. To lower the needle or raise it, turn the hand wheel in your direction. It’s handy for precise stitching and setting the needle position.

8- Bobbin Winder: Thread Winder

The thread is wound onto the bobbin by the bobbin winder, which sits atop the sewing machine. Most machines have it at the top, featuring a bobbin pin, thread guides, and a start/stop lever. It’s where the bobbin is placed for winding, and some also include built-in thread cutters.

9- Throat Plate: Stitch Guiding

A throat plate is a metal part on the opposite side of the slide plate in every sewing machine. It’s right under the needle and presser foot, held in place by screws. The throat plate ensures the needle can sew the fabric smoothly, moving up and down as it stitches.

10- Slide Plate: Bobbin Access

The bobbin door is like a cover for the bobbin case. It’s rectangular and sits close to the pressure foot. To set the bobbin case, the machine operator opens the slide plate and then closes it before stitching. Plus, it makes removing the bobbin case easy, without lifting the machine.

11- Tension Dial: Tension of Thread

By spinning the dial`s tension of the sewing machine you can enhance the tension of the thread and on the tension`s dial, there are numerals like 5, 6, and 7 which adjust tension. By doing this you can change the loops of threads along by enhancing its tension and adjusting disc tension via which thread passes.

12- Stitch Selector: Choice of Pattern

A sewing machine’s selector of stich permits you to select varieties of stitch patterns like straight, zigzag or you can select for embroidery. For many sewing projects, this selector can be used like from simpler tasks to complex ones.

13- Thread Cutter: Thread Snipper

On a sewing machine, a little blade next to the needle region is called a thread cutter. It’s useful for quickly cutting the thread after stitching, which aids in the fabric’s separation from the machine. To use the thread cutter, first, lift the presser foot to release tension.

14- Take-up Lever: Thread Feeding

The take-up lever in a sewing machine is essential for feeding the thread correctly. It moves up and down, pulling the thread and maintaining the right tension during sewing. Positioned between the tension regulator and thread guide, it ensures the thread flows smoothly into the needle.

15- Reverse Lever: Backward Stitching

The reverse lever on a sewing machine allows it to stitch backward. You may use this tool to go back to a particular section of your sewing project or to reinforce stitches. This lever gives you greater control over your stitching, increasing its precision and versatility.

16- Bobbin Case: Thread Tensioning

A bobbin case of a sewing machine firmly grips the bobbin, which grips the thread on the lower side. It provides smooth thread flow and helps maintain tension while stitching. As the needle forms loops, the bobbin spins inside the case, intertwining the upper and lower threads to create stitches.

17- Machine Arm: Needle Holder

The machine arm is the curved section above the needle that houses important mechanisms for needle operation. It includes components like the tension regulator, thread guides, and spool pin. These parts work together to control the thread flow to the needle, ensuring smooth stitching.

18- Light Bulb: Illuminating Work

The light bulb on a sewing machine is a small, electronic component located near the needle bar. Positioned at the machine’s head, it illuminates the sewing area, especially useful when working in low-light conditions.

19- Thread Guide: Tracking Thread

The thread guide maintains the thread’s straight path, dictating its direction and holding an ample supply. It facilitates smooth thread feeding, aiding in the sewing process. The guide ensures proper tension as the upper thread combines with the lower thread in the bobbin case.

20- Tension Regulator: Thread Balance

The tension regulator, akin to the thread guide, ensures the balanced flow of thread during sewing, controlling tightness or looseness. It plays a crucial role in minimizing puckering issues. Operating in tandem with the thread guide, the tension regulator directs the thread into the sewing process, contributing to optimal stitching tension.

21- Power Stich: Control Electricity

The power switch is the gateway for electricity to flow into the machine, available in both manual and electric sewing machines. Typically located on the machine’s right side, it activates or deactivates the machine. Modern sewing machines, often equipped with lighting features, offer flexibility and comfort during sewing.

Frequently Asked Questions:

What functions does a sewing machine’s arm perform?

The sewing machine’s arm includes parts like the tension regulator, tension disk, thread guides, and spool spin. These components work together to drive the needle into the fabric.

What are the main 7 parts of a sewing machine?

In a sewing machine, some of the main parts include the needle, pressure foot, feed dogs, hand wheel, bobbin, thread pin, and reverse lever. Special features comprise a stitch selector dial, stitch length dial, needle, and work light.

What are the fundamentals of a sewing machine?

In simple norms, a sewing machine uses two threads, a top thread from the spool and a lower thread from the bobbin. To start winding the bobbin, put the spool of thread and the bobbin on their designated pins.

What are the sewing machine’s foundations?

The sewing machine functions by using lower and upper threads. From the side of the bobbin, the lower thread has been used and from the spool side, it catches the upper thread. Keep the spool and bobbin of thread on the suitable pins to initiate curving the bobbin.

Describe the sewing foot.

The purpose of a sewing foot is to flatten and smooth the cloth as it passes through the machine in preparation for stitching. It is a little accessory for sewing machines.


Let’s dive into the world of sewing machines and what are sewing machine parts, explaining with functions and unraveling the mystery behind each part and its role. From the trusty needle stitching magic to the bobbin ensuring flawless stitches, each component has a crucial job.

The feed dogs guide the fabric precisely, while the presser foot stabilizes for a smooth finish. The spool holder and foot pedal control thread supply and sewing speed, while the hand wheel offers manual control.

The bobbin winder streamlines thread winding, and the throat plate, along with the slide plate, ensures seamless stitching. With the help of “sewing machine parts explained,” go on an imaginative trip in which each component collaborates to realize your creations.
