Sewing Machine Parts Names Diagram

As we know, a sewing machine is an integral part of any garment industry. Most of the major tasks are performed by sewing machines in this industry. Apart from the garment industry, the sewing machine is also essential in any house because this machine has many applications in our daily routine. The sewing machine is used to repair our torn cloth, curtain, and covers. Due to the repetitive use of sewing machines, regular maintenance is necessary. Sewing machine parts are not so costly. So we can buy them & repair the machine. But, before doing any maintenance, we have to know the parts of the sewing machine, their functions, and their names with diagrams.

Parts of Sewing Machine and their Functions

Spool Pin

The spool is nothing but a small metal rod that holds the spool thread. This spool pin is also called a spool holder. It fixes at one end, and another end tilts to a certain degree. The spool pin is to hold the spool of thread.

Its placing position can be vertical or horizontal depending upon the sewing machine brand. But a horizontal spool pin provides smoother feed.

Bobbin

The bobbin is a cylindrical spindle with a flange on both sides. This bobbin winder spindle wounds the thread in between two flanges.

It is placed in the bobbin during winding. The function of the bobbin is to provide bottom stitches while stitching.

Bobbin Winder Stopper

Bobbin has a particular capacity to store the thread. We can’t insert thread as much as we want. The bobbin winder stopper controls it.

It stops the thread from the collection when the bobbin capacity is rich to a certain level.

Stitch Width Dial

The stitch width dial controls the width between zigzag stitches. Depending on the requirement we can adjust the stitches’ width.

Pattern Selector Dial

The pattern selector dial is to select the type of pattern you want while sewing. It can be achieved by simply rotating the dial into the required pattern. There is the following pattern available in most sewing machines.

1) Straight Pattern
2) Embroidery Pattern
3) Zigzag Pattern

Handwheel

The function of the handwheel is to control the height of the needle by raising and lowering the needle. This process is done only manually with the help of hands.

In almost every sewing machine, the handwheel is on the right side.

Stitch Length Dial

A stitch length dial is available in the automatic sewing machine. The function of the stitch length dial is to control the length of every stitch while sewing.

Reverse Stitch Lever

When we push the reverse stitch lever, sewing happens in the opposite direction. This lever is very time-saving because it will reduce the time to change the direction of fabric when sewing at one end completes. This reverse stitch lever is very helpful while zigzagging.

Power Switch

The power switch is only found in an automatic sewing machine, not in a manual sewing machine. The function of the power switch is to switch On and Off the electric supply.

Most of the time, the power switch is on the right side of the sewing machine.

Bobbin Winder Thread Guide

The function of the bobbin winder thread guide is to guide the thread. It is easy and time-saving because finding the end of the thread is very difficult.

It helps to insert this thread into the needle and prevents the thread from twisting.

Thread Tension Dial

As we know, tension is important while sewing. If we keep low tension on cloth, then stitches do not become proper and create more difficulties while sewing.

If the tension on the cloth is high, then the distance between each stitch becomes more. Hence strength in stitches becomes less.

So, to avoid such trouble, the thread tension dial helps to adjust and control the tension by simply tightening and loosening.

Thread Take-Up Lever

The thread take-up lever is above the presser foot of the machine. Its function is to pull the thread from the spool and feed it to the sewing machine.

It helps to lift the thread when the stitches are complete. The thread take-up lever moves up and down as the needle moves.

Needle Clamp Screw

As we know, the needle will not stand in any place. So, to keep the needle in the same place, we use a needle clamp screw to tighten the screw to fit the needle in one position and not move anywhere.

Presser Foot

Presser’s foot is to press and hold the fabric in position just below the feed dog. Another function of the presser foot is to give stability while sewing.

It also helps to prevent wrinkles while sewing. Many types of presser foot come in marker. Zipper, satin, button stitch, and overedge foot are the typical and most used presser feet in the market.

Bobbin Cover

Bopping cover is a steel plate that acts as a coverall for the bobbin. It protects the bobbin from dust and debris particles.

Bobbin Cover Release Button

It is a button used to remove the bobbin cover by pressing the bobbin cover release button and remove the bobbin cover and access the bobbin.

Feed Dog

The function of the feed dog is moving the fabric in forwarding and backward positions depending upon the requirement.

It is usually visible to our eye because it is on the needle plate. We need to change that feed dog and place a new one if it damages.

Needle

The needle is helping to give stitches in the fabric that we have sewed. Different types of needles are available depending upon the type of fabric. These needles are easily removable and clamped in a needle clamp.

Needle Plate

A needle plate is a metal plate that is available below the needle and presser foot. The function of the needle plate is to move the fabric in a forward position while sewing.
