The Jack JK‑S5‑91 is a high-performance industrial post-bed lockstitch sewing machine designed for sewing difficult shapes and 3D materials such as shoes, bags, leather goods, and cylindrical products.
It features a post-bed (column type) structure, which allows easy handling of curved and tubular items where flatbed machines cannot operate efficiently. The machine is equipped with a triple transport system (needle feed + bottom feed + roller foot) for stable feeding of medium to heavy materials.
With a direct-drive servo motor, it provides quiet operation, reduced vibration, and energy efficiency, making it suitable for long-hour industrial production.
