ASM911 Flagship High-Speed, Automatic Pattern Sewing Machine |The Flexible Workhorse for Heavier Thread

Compared to smaller models, the key advantage of the ASM911 is its large rotary hook featuring triple the bobbin capacity, which allows you to use thicker structural thread up to 840D/3. Heavier thread is a critical factor in ensuring the ultimate tensile strength of safety harnesses and fall protection equipment.
Because safety harnesses often require multiple reinforcement tacks across a wide area—such as waist belt and leg loop intersections—the ASM911’s expansive 300 x 200 mm sewing field allows you to sew multiple joints in a single automated cycle, drastically reducing labor time.
Choose the ASM911 if you want to balance cost and production volume while utilizing heavier structural thread or a larger sewing area to create multiple pattern tacks across the harness joints.
