General
The high-speed lockstitch buttonholing machine incorporates an electronically controlled cloth feeding mechanism. Using a new technology called "active tension" (electronic thread tension mechanism), the machine is capable of not only duplicating the same sewing conditions with ease but also of ensuring upgraded seam quality with consistency.
