The Jack JK-T373GR-Z is an advanced automatic button sewing machine designed for high-speed, high-precision garment production. It features a single-needle chainstitch system combined with an automatic button feeding mechanism, which significantly increases productivity by eliminating manual button placement.
Equipped with a direct-drive servo motor, this machine ensures quiet operation, low vibration, and energy-efficient performance. The entire feeding and positioning process is controlled by stepper motors, enabling accurate button placement and automatic rejection of incorrectly positioned buttons.
The machine supports multiple stitch configurations (8, 16, or 32 stitches), allowing flexibility based on fabric type and sewing requirements. With automation features such as automatic thread trimming and presser foot lifting, it delivers consistent, professional results with minimal operator effort.
It is ideal for sewing buttons on garments such as shirts, uniforms, coats, and workwear, especially in high-volume industrial production environments.
