Sewing Machine Technical Terms

If you are a beginner or upgraded yourself and gained some experience, this article will help you to learn every pros and cons about the machine you are operating. If you want to buy a sewing machine, this article will also help you to learn some of the major factors. Today I am going to explain technical terms of a sewing machine.  Let’s begin:


The first thing you need to learn about a sewing machine is its bobbin. A bobbin is a metallic and round device which carries the spool of thread right under the needle. The old sewing machine had a different system for this.

It was inserted from the underside of the machine. But with the modernization of sewing machine, you can move a top cover of your machine and drop the bobbin. You can also ensure weather the thread is running out or not.

Needle Plate:

It is metal plate under the pressure foot and needle and over the feed dog. It has holes that help the needle to go through and help you to place the fabric with a perfect distance from the needle and follow a straight line while sewing.

Foot pedal:

It is a pedal operated by your foot to run the machine, but some modern sewing machines are equipped with start-stop button for automatic sewing.

Pressure Foot:

It’s a very sophisticated instrument. It is almost flat piece of metal which holds the fabric flat and plane against the needle plate. Presser foot varies with their functions and they are very easy to change. They usually screwed or clipped with the machine.

Feed Dog:

It’s the teeth like metal chains which situated directly beneath the needle and presser foot. Its main function is it pulls the fabric forward in a straight line while sewing. Some sewing machines have to feature to sew without the feed dog as it allows you to move the fabric freely.

Walking Foot:

It’s a special kind of pressure foot. It works together with the feed dog. When you sewing layers of fabric, they both keep the fabric aloof from slipping and allow you most accurate stitch.

Free Arm:

It a cylinder which is appointed to help you while sewing pockets or sleeves.

Tension Disc:

It’s the combination of two concave disc and they are put together facing each other. The thread is supposed to pass by this two while the tension of the thread is adjusted by a spring and nut mechanism.

  • Handle Wheel:

The Handle wheel is used when you want to move the needle up and down manually. You can use handle wheel sewing extremely thick fabric or when you want to sew a complicated design very carefully and slowly.

  • Take Up Lever:

It is used to maintain the tension of the thread in a proper standard and threading the machine. It is very viral because if the take up lever is threaded inappropriately, the thread will jam the machine by knotting up.

  • Back sew Button:

When you want to sew back words, you can use the button on the front of the machine. Generally it’s required to tie off the seam. Backward sewing is almost same to the normal sewing except the direction.

I hope it is now easier for yourself to identify different parts of your sewing machine.
