Key Features

• Triple-feed (unison feed) system — walking foot, needle feed, and bottom feed all move together — prevents material slipping and puckering on leather, foam-backed upholstery, and multi-layer canvas
• Four needle gauge options (1/4", 5/16", 3/8", 1/2") let you match the machine to your application — tighter for bags and garments, wider for upholstery and automotive seams
• 750W Servo motor delivers quiet, energy-efficient operation with precise speed control from slow crawl to full production pace
• Automatic lubrication system reduces maintenance intervals and protects the machine during long production runs
• Flatbed construction provides a full, flat sewing surface — ideal for large panels, upholstery cushions, bag bodies, and canvas work
• Lockstitch formation produces strong, secure seams that resist unraveling — suitable for structural and decorative applications alike

Ideal For

• Leather goods and handbags — parallel topstitching with consistent gauge across the full panel
• Upholstery and automotive interiors — double-needle seaming on vinyl, leather, and foam-backed materials
• Canvas, webbing, and heavy textile work — heavy-thread parallel stitching on belts, straps, and covers
• Any production application where consistent twin-needle spacing and reliable material feed are required
