Overlock
An overlock is a type of sewing machine and technique widely used in clothing manufacturing to create professional, durable seams and prevent fabric edges from fraying. It's also known as a serger in North America. This machine sews, trims, and finishes seams all in one step, making it essential for mass production of clothing. When candidates mention overlock experience, it means they can operate these specialized machines that are fundamental in garment production. Think of it as the industry-standard way to create strong, clean seams in clothing manufacturing.
