Heavy Duty Compound Feed Lockstitch (Thick Thread) Sewing Machine FX6400
This is the latest model in the FOXSEW heavy-duty compound feed lockstitch sewing machine series, designed for high-performance applications. The FX6400 is ideal for stitching thick materials such as sofas, car seats, safety belts, airbags, and other heavy-duty fabrics. It features a large vertical rotating hook for efficient thread loop catching and sliding bars for smooth thread up-taking.
The FX6400 series includes several models:
- FX-6400 (Single-needle)
- FX-8400 (Double-needle)
- FX-6400H (Single-needle)
- FX-8400H (Double-needle)
The FX-6400H and FX-8400H models are upgraded versions of the standard FX-6400, with an increased needle gauge to 13mm for enhanced durability. These machines are equipped with needle bearings for both the arm shaft and hook shaft, cog belt driving, plunger pump lubrication, and compound feed systems via the needle bar, presser foot, and feed dog. This combination ensures smooth operation, quiet performance, and long service life.
A safety clutch is also included to protect the hook from damage during overloading. These machines are widely used in industries such as automotive, furniture, luggage, and outdoor gear.
