Differences Between Flatlock and Coverstitch Machines?

[DiEva]

Flatlock Machine: Used for seaming. Coverstitch Machine: Also known as a cover seam, used for edge finishing and seaming. The flatlock sewing machine primarily uses a single thread to form a stitch on the fabric, interlocking or sewing one or multiple layers of material together. It is generally categorized into two types for thin and thick materials. Flatlock machines can sew fabrics such as cotton, linen, silk, wool, synthetic fibers, as well as leather, plastic, and paper products. Thin materials are typically used for knitwear, underwear, shirts, uniforms, etc., while thick materials are used for various sportswear, denim, fashion, etc. The stitch produced is the simplest type, resulting in neat, aesthetically pleasing, uniform, and durable stitches. The coverstitch machine uses binding tape to encase and stitch the raw edges of cut pieces. If plain edge finishing is used, the seam may become too bulky with too many layers of fabric, which could make fitted garments uncomfortable to wear. However, by using stitch types 602 or 605 on the coverstitch machine to encase the raw edges of the binding tape, the number of fabric layers in the seam can be reduced from five to three. Alternatively, stitch types 406 or 407 can be used, and a specialized edge-finishing attachment can be installed on the sewing machine to further reduce seam thickness and improve operational efficiency.
