Components of a Sewing Machine
The sewing machine is one of the most essential tools in the realm of textiles, and below are the key components that make up this vital piece of equipment:
Pressure Adjustment Thumb Screw
Referred to as the thumb screw due to its operation being controlled by the thumb, this component regulates the pressure of the presser foot. This screw plays a critical role during the sewing process; the presser foot must remain down while sewing, and it is lifted at the end of the task to release the fabric from the machine.
Sewing Machine Arm
Commonly known as the arm or body of the sewing machine, this part typically features a curved shape. Some seamstresses may experience difficulties while sewing with this arm in place, leading them to temporarily remove it for ease of use before reattaching it afterward.
Balance Wheel
This component, often called the balance wheel or manual wheel, is positioned adjacent to the sewing machine arm. It serves as a mechanism to start and stop the machine, making it an indispensable tool. Notably, in certain models, the balance wheel can be utilized for manual operation of the sewing machine.
Sewing Shuttle and Bobbin Winder
Selection of the thread for sewing is crucial, with careful consideration given to the color and type of thread used in the bobbin. The bobbin winder, which is a small wheel, is then used to fill the bobbin with the chosen thread. This component is vital to the functioning of the sewing machine, and any malfunction here can hinder the machine’s performance.
Thread Lift Lever
Known as the thread lift lever, this component plays a significant role during the sewing process, as the upper thread passes through it, allowing it to move up and down, thereby activating the sewing needle.
Sewing Needle, Needle Plate, and Needle Holder
The sewing needle is one of the most critical components of the sewing machine, as it is responsible for creating the stitching on the fabric. The needle plate, which is a metal plate, provides a surface upon which the fabric rests, allowing the needle to operate above it. The needle is secured in place by a holder that keeps it stabilized during use.
Presser Foot
The presser foot is an essential tool for securing the fabric in place while sewing. For instance, when installing a zipper, the presser foot assists in holding the fabric steady. This tool comes in various shapes and sizes, tailored to accommodate different types of materials being sewn, whether leather or other fabrics.
Power Switch
This switch is typically located on the right side of many sewing machines, and it is used to turn the machine on and off.
