Power, Control & Post-Bed Advantage

• Post-bed construction provides superior access to tubular, curved, and 3D items where flat-bed machines struggle.
• Double needle lockstitch lets you sew two perfectly parallel seams in a single pass—both decorative and structural.
• Unison feed (Triple feed) walking foot system (bottom feed + needle feed + walking foot) keeps multiple layers moving together, preventing shifting and puckering on thick or slippery materials.
• Servo motor drive offers excellent speed control, high torque at low speeds, reduced noise, and lower power consumption—ideal for precision work and long production runs.
