An overlock sewing machine, also known as a serger, is a specialized machine designed to trim, sew, and finish fabric edges in a single operation. While a regular sewing machine can handle most basic sewing tasks, an overlocker creates professional-looking seams that are stronger, neater, and more durable.
Overlock machines are widely used in garment production because they prevent fabric edges from fraying while maintaining the natural stretch of the material. This makes them especially valuable when working with knit fabrics, sportswear, lingerie, and other stretchy textiles.
