The LS20-3 Overlock Seaming Sewing Machine is a specialized industrial sewing machine designed for overlock stitching, particularly for FIBC (Flexible Intermediate Bulk Container) bags. Part of the GN20 series, this machine is engineered to handle thick threads and provide stable performance, making it ideal for heavy-duty applications in industries such as agriculture, construction, and logistics. Its versatility allows it to be adapted for various tasks, including carpet overseaming and fishing net overlock sewing, offering a cost-effective alternative to more complex machines like the 81300 series.

The LS20-3 is a single-needle overlock machine designed for 2-thread FIBC bag overlock applications. It features an overlock width of 10-12mm, ensuring durability and strength in seams. Unlike the 81300 machine, which combines overlock and chain stitch (401), the LS20-3 focuses solely on overlock stitching (502), making it a simpler and more affordable option for specific manufacturing needs. This machine is particularly suited for applications requiring high stability and precision, such as the production of jumbo bags and industrial textiles.
