3-Thread Overlock Sewing Machine with Adjustable Stitch Length and Width, Fixed Presser Foot

Professional 3-Thread Overlock Machine for Light and Thin Fabrics This 3-thread overlock machine is designed to create firm, stable chain stitches on light and thin fabrics, preventing edges from loosening during wear and washing. The concealed chain stitch offers higher elasticity, making it particularly well suited to sewing underwear and other garments that need to stretch and recover comfortably in use. Adjustable Stitch Length and Overlock Width Stitch length can be adjusted between 1.5 and 3 mm, while overlock width ranges from 3 to 4 mm, giving you flexibility to match different edge sealing requirements. The stitch tension adjustment helps maintain even thread tension and consistent thread force while sewing, reducing the risk of fabric stretching or puckering. Durable Cast Iron Construction Built with cast iron technology and a surface baking finish, this machine is wear resistant and less prone to rust. The fixed presser foot and needle lining with nut help prevent stitch omissions, supporting a stable and neat stitch line throughout your work. Suitable for a Range of Fabrics This overlock machine handles multi-layer fabrics including silk, linen, cotton, wool and chemical fibres, as well as single-layer edges using three or four thread configurations. It offers a quick and straightforward way to finish seams neatly on a variety of sewing projects.
