This machine uses multiple threads (usually 3, 4, or 5 threads) to create strong, stretchable stitches that prevent fabric from fraying. At the same time, a built-in cutting blade trims excess fabric, ensuring clean and uniform edges. This combination of cutting and stitching makes it much faster and more efficient than ordinary sewing machines.
Overlock machines are equipped with a powerful motor that supports high-speed operation, making them ideal for bulk production and continuous use. They also feature adjustable stitch length, width, and thread tension, allowing users to work with different types of fabrics, from light materials to heavy textiles.
