The JACK JK-T1903GD Computerized Lockstitch Button Stitch Machine is a high-performance industrial button attaching machine designed for precision, speed, and versatility in modern garment manufacturing. Featuring an intuitive touch panel control, the JK-T1903GD enables operators to easily select sewing patterns, adjust parameters, and monitor machine functions through a user-friendly LCD interface with voice guidance.

Built on JACK’s advanced 1900/1903 electronic sewing platform, the machine delivers secure lockstitch button attachment, ensuring buttons remain firmly fixed and are less likely to unravel than conventional chain stitch button sewing. The computerized control system supports multiple button sewing patterns and allows users to create or modify patterns directly on the machine or import them from a PC, making it suitable for a wide range of garment applications.

Powered by an energy-efficient direct drive servo motor, the JK-T1903GD offers smooth operation, low vibration, reduced noise, and high sewing accuracy. Its integrated automatic functions help improve productivity, reduce operator effort, and deliver consistent button attachment quality for shirts, uniforms, jackets, workwear, denim, and fashion garments.
