Bobbin and Bobbin Case

The lower thread is wound onto a low spool, which is the bobbin. The bobbin and the needle thread are looped together, making up the underside of a machine stitch. Meanwhile, the bobbin case holds the bobbin. Tension is provided to the bottom thread via the bobbin case. When the needle thread is pulled around the bobbin case, it wraps around the bobbin thread and drags it up through the needle plate.


The bed is basically your work area. Your sewing machine’s flat section stabilizes the machine and extends your workspace where you can place your projects. This is also where the feed dog is practically mounted.

Presser Foot

The presser foot applies pressure to the fabric and holds it in place on the feed dog. This provides support for your sewing machine as you work. Your machine’s lever serves as its control.

Its position may differ, depending on the type or brand of your sewing machine. Presser feet types also come in a wide variety of designs; zipper, satin, button stitch, and overedge foot are just some of them, depending on your process or the textile you are using.

Feed Dog

The presser foot and throat plate are connected by a set of small teeth, either metal or rubber, that draw the fabric through the gap. By controlling how much fabric flows through at a time, the feed dogs also control stitch length. Allow this mechanism to move the fabric instead of your hands while guiding it. The needle can bend or shatter when pulled or pushed too hard with your hands.


A needle is a small, thin metal rod with an eye through which a thread can pass. A needle is essentially what’s needed to stitch. However, different types of needles like steel needles coated with chrome or titanium are utilized for woven fabric and denim, lather, knit fabric.

Needle Clamp

This holds the needle in place and tightens it. It also ensures that the needle is steady and won’t move during the sewing process. 

Tension Discs and Tension Spring

The tension discs regulate and control the thread tension to ensure a proper stitch on the fabric. The stitch may not be placed properly if there is a tension issue; it may be too loose or too tight. A tension spring is used to manage the pressure to ensure appropriate stitching while joining two different textiles. If the tension discs and springs are worn out, they will need to be replaced. Options for sourcing include going local or overseas if you require a huge number of anything like this from China or another place.

Throat Plate

This metal plate, which is often referred to as a needle plate, is located beneath the needle and presser foot. A little slot in the plate lets the needle pass through and permits the bobbin thread to come out. There are little notches in the throat plates that guide seam allowances and straight stitching lines. You can simply remove the plate for you to clean underneath.

Stitch Indicator Plate

On the Stitch Indicator plate, a different stitching number is written to identify the sort of stitching that you want. Even though this plate is a permanent fixture of the machine, it should nevertheless be cleaned to ensure that the written number is visible.


If you want your machine to last for a long time, you have to make sure it is regularly maintained. Cleaning and adding lubrication appropriately will prevent technical problems or improper operation. Here are some ideas for the upkeep of your machine.

  1. Read the machine’s manual and follow the setup instructions before you start sewing.
  2. Clean it up after using it to prevent dust from accumulating.
  3. If a thread gets stuck in the bobbin casing, don’t apply any extra pressure.
  4. Invest in high-quality accessories and equipment.
  5. Put good quality lubricants in the proper location regularly.
