Industrial sergers are specialized sewing machines designed for high-speed and efficient stitching in manufacturing settings. They use multiple threads to create overlock stitches, which help to finish edges and prevent fraying. This makes them ideal for working with various fabrics, including knits and woven materials, commonly used in the apparel industry. These machines are built for durability and can handle large volumes of work, making them essential in factories and production lines. Industrial sergers often come with advanced features, such as adjustable stitch lengths and widths, allowing for greater versatility in sewing projects.
