Core Advantages
Many traditional thread sewing machines suffer from loose thread ends that affect product appearance and durability. The patented Thread End Lock design directly addresses this problem by anchoring thread ends within the last few stitches. After manual feeding, all core forming procedures operate automatically to reduce human error. The inward folding structure meets standard book block specifications for notebooks and account books. Precise fiber optic sensing ensures reliable sewing cycles, supporting stable continuous operation for large batch orders.
