Description

Jack F6 High-Speed Direct-Drive Lockstitch Sewing Machine

High-speed single-needle lockstitch machine designed for efficient sewing of light- to medium-weight materials in garment manufacturing, tailoring and general industrial sewing applications.

The Jack F6 is a new-generation industrial lockstitch machine equipped with an integrated energy-saving direct-drive servo motor. The compact motor design provides quiet operation, reduced vibration and improved energy efficiency while eliminating the need for a conventional belt-driven motor system.

The machine features improved material-handling performance and can sew through multiple layers of fabric, including up to approximately 15 layers of denim under suitable conditions. Its electronic control system allows easy adjustment of sewing speed and needle stopping position, making the machine suitable for both high-speed production and precision sewing operations.

With automatic lubrication, an integrated LED work light, bobbin winder and stitch-by-stitch function, the Jack F6 provides a practical and reliable solution for garment factories, tailoring units and industrial sewing workshops.
