What Is A Sewing Machine And Its Key Parts?

what is a sewing machine used for

A sewing machine is an incredible machine used to sew up materials and fabric together using a thread. Sewing machines have, for many years, improved the productivity and efficiency of the textile industry globally. The available sewing machines vary in size, cost, appearance, and efficiency. 

The primary working principle of sewing machines is not that complex. However, you need to know the different parts of a sewing machine. With this in mind, you will find it easier and efficient to sew different types of fabric. These parts include:

Power Switch

Locating the power switch may seem an easy task, but it’s the first step towards learning how a sewing machine works. The power switch location may vary depending on the type of sewing machine you own or want to use. But you will typically find it on the right side of the machine. 

Spool Pin

A spool pin is a small metal or plastic pin that holds your sewing thread spool and sticks out on the top of your machine.

Thread Guide

The thread guide is a geometric metal piece that directs sewing thread from the spool to the bobbin winder. Also, it helps control the tension of the thread when the machine is in use.

Bobbin Winder

You will also find the bobbin winder on the top of your sewing machine. It’s a metal or plastic pin that works together with a bobbin winder stopper and the spool of thread to wind thread evenly onto the bobbin before you start sewing.

Stitch Adjustment Buttons

The stitch adjustment buttons help pick the type of stitch you create, its length, and the direction it will move, forward or reverse. Each button on the machine plays a specific role. 

Take-up Lever

When you are ready to thread your machine, the top thread will pass through the take-up lever. The metal lever will move up and down in tandem with the needle. You will find the lever on the front left side of your sewing machine. 

Tension Dial/ Regulator

The tension dial helps regulate the tension on the top thread as you sew. With suitable tension, the bobbin thread and top thread will work together in even stitches. 

Keep in mind that if the tension is too tight, the stitch will pull together and break. And if it’s too loose, the stitches will not hold and will loop on the garment you are sewing. 

Needle Clamp Screw

The needle clamp screw holds the needle in place when you are sewing. You will find this screw under the arm of your machine. 

Presser Foot

The presser foot helps hold the fabric in place and steers it through the sewing machine.

Needle Plate

This metal plate is located below the presser foot and the needle. The small opening in the plate allows bobbin thread to come out and the needle to pass through to make stitches. 

Feed Dogs

The feed dogs are the rubber or metal teeth that pull the fabric between the needle plate and presser foot. They also help regulate the stitch length by controlling the amount of material used or passing through as you sew.

Setting up Sewing Machine Stress-Free

Sewing machines vary a little bit from one model to another. You need to know how to set up the available model and ascertain more about how it works. If you have your manual handy, you may want to check it out and grasp specific instructions tailored to your model.

With your sewing machine, it’s easy and fast to make your clothes as per your preferences. Repairing torn or worn clothes should no longer be a hassle. If you are familiar with a sewing machine’s different parts or have used one before, it shouldn’t be daunting to assemble it and get started.

Every step matters as you set up your machine, so be cautious in your undertaking. Here are few things to keep in mind. 

  • Threading the Needle and Bobbin

While sewing, you need to form stitches. The bobbin and your needle will help in your endeavors. Get your machine going by inserting the thread through the hole in your Spool pin and then wind it around the bobbin. Make sure it is locked into place. 

Go on and place the thread on the spool and apply some tension on the pedal. Watch how the bobbin will wind the yarn. 

  • Loading the Bobbin

Once you have loaded your bobbin, the next step shouldn’t be taxing. Figuring how to load the bobbin is an easy stretch towards learning how a sewing machine works. Follow the specified instructions on your manual on the direction the thread should be going. 

  • Thread Specified Parts of the Sewing Machine

Your sewing thread needs to reach the top parts of the machine. Guide it, making sure it is away from the spool, and you can easily insert it through the eyes of the needle. Make sure the thread is correctly stretched and not too tight or too loose. Your machine will be ready for use, and you can go ahead and learn how it sews different types of fabrics. 

How a Sewing Machine Works- Key Mechanisms Involved

how a sewing machine works step by step

How a sewing machine works involve learning how every part of the equipment operates and how each stitch forms. It’s a step-by-step process undertaken repeatedly to get that perfect seam you are seeking. Here are the fundamental mechanisms that define how a sewing machine works. Have a look:

1. The Needle Mechanism

Understanding the anatomy of a sewing machine starts by looking at how the needle works. Needles determine how your machine makes stitches. The different parts that make a sewing machine needle help determine how it works. 

The shaft helps drive a motor while the crankshaft pushes the needle to rise and fall as you sew. The crank will keep the engine in motion while the needle reciprocates by moving up and down. The efficiency of your sewing machine needle is determined by the length and shape of its essential parts.

The essential parts of a sewing machine needle include:

  • Shank- It’s the upper part of a needle that is inserted into the sewing machine.
  • Shaft- The area that contains the point of the needle, eye, scarf, and groove.
  • Groove: The area that stretches to the needle’s eye and the place where the thread rests.
  • Scarf – It makes it easy for the bobbin case hook to intersect with the thread and make stitches.
  • Eye- The eye carries the thread you use for sewing fabric. It’s advisable always to pick a needle with the perfect size. A too large or small needle eye will cause the thread to break as you stitch.
  • Point- It helps determine how a needle pierces or passes through a material. Common needle points vary depending on the type of fabric you are using. Sharp needle points are great for woven fabric, ballpoint needles exceptional for knit fabric, while universal needle points are excellent for knit and woven fabrics.

2. The Shuttle and Bobbin Mechanism

The bobbin and shuttle of a sewing machine help make stitches. However, they have to rotate faster than the needle to ensure the whole sewing process is effective. The shaft has to move the shuttle more quickly, and a loop stitch is then created while the take-up lever will ensure it is tight enough to last a lifetime. 

The machine will make a stitch by holding the bottom thread coming from the bobbin. The needle will then pull the next part of the thread back up through the fabric. Depending on the rhythm of your sewing machine, two threads will intertwine to make a lock stitch. 

3. The Feed-dog Mechanism

When stitching, you have to ensure the stitches are of equal length, and this is where the feed-dog application comes in handy. Feed dogs are thin teeth that move back and forth as you sew and determine how effective your machine will be for day-to-day use.

The feed mechanism determines how your sewing machine will work. Feed dogs will move a fabric forward to the stitching zone of your appliance. These teeth-like points move as you stitch and will gently grip your material as it passes through the sewing machine.

If your feed dogs work flawlessly, you will not have any worries sewing as you will produce high-quality stitches. The sewing machines you find in the market come in varying feed dog mechanisms that determine their performance. The known types of sewing machine feed mechanisms include:

  • Needle feed mechanism- Sewing machines that use double needles embrace the needle feed mechanism. The machine will rely on its needle as the key feeding component that pushes the fabric for stitching. 
  • The drop or regular feed mechanism involves the movement of feed dogs horizontally as they drag a fabric to the stitching machine.
  • Puller feed mechanism – Machines that use the puller feed mechanism have rollers that catch and pull material to be stitched. The puller feed mechanism is used in stitching heavy and oversized materials like tents, leather upholstery, or automotive covers.
  • Differential feed mechanism – Sewing machines that utilize the differential feed mechanism come with two independent feed dogs. These teeth-like folds are easily manipulated so that the fabric to be stitched is compressed as one wishes.

Vital Techniques That Make Sewing Machines Effective

When every sewing mechanism is well-coordinated, it is not that hard to come up with flawless stitches. The mechanical sewing process involves knowing several things.

1. Double-Threaded Stitching

The needle is a crucial element when you are making a handmade stitch. You have to press the needle through the material and pull a single thread as you stitch the fabric. With a sewing machine, you don’t have to rely on the needle all the time.

Its fundamental purpose is to pierce the material to push through one thread. You will make a knot with the second thread before it’s pulled back up. Here is how double-threaded stitching works:

  • Tie the needle to the spool thread. It will pass through the fabric and the needle plate.
  • The needle will rise slightly so that the thread folds into a loop as it is pushed against the needle plate.
  • The loop will be caught by the bobbin case, which widens it. It will make a circle, and the bobbin will ensure a second thread is available. 
  • You will make a knot after the hook’s rotation is complete. 
  • Lastly, the needle will pull the upper thread back up to tighten the already made knot. You will have your stitch, and the cycle can go on as you wish. 

2. Stitching and Fabric Synchronization

The sewing mechanism will only be effective if every part of the machine is working perfectly. The motor has to rotate and work effectively. It’s only possible if the mechanism of the cranks, belts and drive shafts is effective. 

There will be a synchronized movement of the needle and the threads you use. The presser foot and the feed dogs have to be in perfect shape to ensure the stitching mechanism is successful. They have to help pull the fabric between stitches.
