Overlock machines, often referred to as sergers, are specialized sewing machines designed to stitch over the edge of fabric. They trim, sew, and finish seams simultaneously, creating clean and durable edges. These machines are widely used in garment manufacturing, textile production, and home sewing for professional-quality finishes.
The purpose of overlock machines is to improve seam strength and prevent fabric fraying. Traditional sewing machines can create seams, but they often require additional steps to finish edges. Overlock machines simplify this process by combining multiple functions into a single operation.
They exist because modern textile production demands speed, precision, and consistency. Whether in industrial factories or home setups, these machines help maintain quality standards while increasing productivity.
