A sewing machine is a very important instrument for garment making. There are many kinds of sewing machines, but their basic structure is the same, whether they are treadle machines, electric sewing machines, or hand-operated machines. I will explain here some of their basic parts and their functions so you can understand the machine better, which in turn, will help you in your sewing.
Sewing machines go back a long time. The Industrial Revolution gave us the first sewing machines to offer relief to the manual sewing work. Off course, they have gone through many changes and improvements since then. You can sew an exclusive dress with a high-end luxury fabric with these machines now at home.
Basic Parts of a Sewing Machine
The basic parts include needle, needle plate, spool pin, presser foot, hand wheel, stitch dial, thread tension dial, tension disc, power switch, and many more.
This is fitted at the top of the arm and holds the reel or the spool of thread.
A rod made of steel that holds the needle at an end with a clamp. The bar gives the needle motion.
As the name suggests, this is the on/off switch. It is usually located at the machine’s right side.
Thread Take-Up Lever
This lever is fitted to the arm’s body. The top thread passes through this lever in an up and down motion with the needle during the process of sewing. The loop that is formed is also tightened.
The fabric is held firmly at the right place with this foot. You have to press the bar to lower it to hold the fabric.
Presser Foot Lifter
This is a lever that is attached to the presser bar. Its purpose is to lower and raise the presser foot.
The case moves into position for catching the top thread and forming the stitch when you lower the needle into the bobbin chamber.
Bobbin Binder Spindle
The bobbin is kept here during winding.
Bobbin Cover Release Button
It releases the cover for the entrance to the bobbin.
Bobbin Winder Stopper
The bobbin winding process stops when the bobbin reaches optimum capacity.
Bobbin Winder Thread Guide
These guides help in the process of bobbin winding. They hold your thread in the right place to the needle from the spool.
The motion mechanism works when the wheel revolves.
Stitch Length Dial
The dial is useful for controlling the stitch’s length.
Reverse Stitch Lever
The sewing machine works in reverse when you push this lever.
This is used for forming stitches on the garments.
This is a metal plate located below the presser foot and needle. The plate, which is a semi-circular disc with a hole, allows the fabric to move forward when you are sewing. The needle passes through this hole.
Thread Tension Dial
The dial controls the top thread’s tension.
There are two concave discs where the sides are in convex shape. The sides face each other. Threads pass through these sides. A spring adjusts the tension of the thread. There is a nut that decreases or increases the pressure.
Located at the machine’s right side, the wheel lowers or raises the needle.
Stitch Width Dial
It controls zigzag stitching.
Pattern Selector Dial
This dial sets the symbol of the stitch pattern you want.
