What is the primary purpose of the Serger sewing machine?

• A. To prevent unraveling of cut edges
• B. To attach zippers
• C. To stitch hems on leather
• D. To sew buttons onto shirts

Answer: (A)

Serger machines are built to finish raw fabric edges and prevent fraying. They wrap the edge with an overlock stitch from multiple threads and often trim away excess fabric as they sew, producing a neat, durable edge in one pass. This edge finishing is the main reason sergers are used, especially for fabrics that fray easily or curl at the edges. Other tasks—like attaching zippers, stitching hems on leather, or sewing buttons—are handled better by other tools or machines, not by the serger’s primary function.
