The Needle

The needle is an essential part of your machine, as it is responsible for transferring the fabric through the machine. This action causes the material to be stretched and the needle to puncture the fabric a few times. This process of puncturing the fabric and pulling it through is how a sewing machine sews the two pieces of fabric together.

The Bobbin

The bobbin is the small metal or plastic spindle that holds the thread as the needle moves along it. Keeping the bobbin clean is important so the thread doesn’t become tangled, and the stitching is smooth.

The Presser Foot

The presser foot is the little foot on the front of a sewing machine that helps you attach the fabric to the seamstress’ bobbin. It’s a metal or plastic foot that has a roller on it. When you place the fabric on the presser foot and press down, the roller grabs the fabric and pulls it toward the bobbin.

The Handwheel

The handwheel is a sewing machine component that helps move the fabric as you sew. It helps to keep the fabric taut as you sew, and it allows you to change the tension on the fabric as you sew.

The Feed Dog

Feed dogs are small metal or wooden pieces that are attached to the back of a sewing machine, just in front of the spindles. The feed dogs help to feed the fabric under the machine’s needle through the machine’s fabric wheel.

Other essential parts of sewing machines

As we said, sewing machines are made out of many parts. We already mentioned the most major and important ones, but what about the others? The following are other machine parts that make its work possible.

The Bobbin Winder

A bobbin winder is a small, round device inserted into a machine’s stitch wheel. It is used to wind the threaded yarn onto the bobbin, a round spindle located in the machine’s wheel. When you sew, the bobbin is interwoven with the yarn, and the thread flows smoothly through the device.

The Thread Cutter

A thread cutter is a specialized tool used in a sewing machine to remove the fabric threads left behind when the fabric is sewn. Having a thread cutter on hand is crucial if you frequently make alterations to your sewing project. Not having a thread cutter can often result in frustrated sewing.

The Spool Pin

The spool pin is a small, circular piece of metal that sits inside the sewing machine’s spool, and it’s responsible for moving the fabric as the machine stitches it together. When you press the pedal to start the machine, the spool pin rotates, which pulls the material out of the bobbin and starts the machine threading it.

The Stitch Selector

A stitch selector is a key feature on a sewing machine that allows you to select the type of stitch you want to use. There are a variety of stitches that can be used, including a zigzag, serger, and straight stitch. Each of these stitches has its own specific uses and benefits.

What To Do If Your Sewing Machine Has A Broken Part?

If your sewing machine has a broken part, you’ll need to take it to a Sewing Machine Repair Shop. They will be able to replace the part and get your machine working again. Before you go, be sure to have the following information:

  • The make and model of the sewing machine
  • The serial number of the sewing machine
  • The part that needs to be replaced
  • The cost of the part

What About The Old Sewing Machine Parts?

Old sewing machine parts can be a treasure trove of value. If you know what to look for, you can find parts in good condition that can be used to restore or refurbish your old sewing machine.

The first thing you need to do is assess the part’s condition. Is the part torn or damaged? Is the part rusty? Is the part stained? Once you’ve assessed the condition of the part, you can decide whether to keep it or discard it.

You’ll need to clean the part if you decide to keep it. You can use a gentle soap and water solution or a commercial cleaner. Make sure to clean all the dirt, rust, and stains off the part. Once the part is clean, you’ll need to assess the condition of the thread. Is the thread twisted and knotty? Is the thread brittle? Is the thread dull? If the thread is in poor condition, you’ll need to replace it.
