An overlock sewing machine (also known as a serger) is a specialized sewing machine designed to trim, stitch, and overlock fabric edges in one operation. It creates strong, neat seams while preventing fabric from fraying, making it ideal for professional garment finishing.
This machine uses multiple threads (usually 3 to 5 threads) and loopers to form secure overlock stitches that are commonly used in clothing manufacturing. It can sew at high speeds, allowing tailors and garment factories to produce clean and durable seams quickly and efficiently.
