Power & Extended Control

The 900W servo motor provides exceptional torque and quiet, energy-efficient performance. Combined with a needle positioner and pneumatic functions, operators can achieve precise turns, quick foot lifts, and convenient reverse stitching without stretching across the extended arm.

Built for Oversized Projects

The 30-inch long arm offers unparalleled clearance for bulky assemblies, making it easy to maneuver sofas, large bags, boat covers, and industrial fabrics. The rectangular feed mechanism and unison feed system ensure consistent seam quality and smooth feeding, even with multiple layers of leather, canvas, or vinyl.
