FOXSEW FX-8341 Double Needle Cylinder Bed Lockstitch Sewing Machine for Filter Bags
This high-performance sewing machine is specifically designed for manufacturing filter bags and other cylindrical products. It features a double needle system with a cylinder bed, ensuring precision and efficiency in stitching. The unison feed mechanism combines the movement of the needle feed dog and the presser foot, preventing fabric slippage and creating a neat, secure lockstitch.
Equipped with an imported vertical double rotating hook and sliding thread take-up, this model delivers strong and consistent stitches. The synchronized tooth belt drives both the arm shaft and hook shaft, ensuring smooth operation and durability. A knob-type stitch regulator and lever-style reverse feeding mechanism make it easy to adjust settings and handle different materials. Additionally, a clutch safety device is included to protect the machine from potential damage.
Ideal for industrial use, the FX-8341 is widely applied in sewing tents, canopies, umbrellas, seat cushions, sofas, saddles, harnesses, shoes, footballs, hot air balloons, luggage, and more—especially for cylindrical filter bag production.
