The Jack JK-T1903GR-DII buttonholer is specially designed for sewing flat buttons with diameters ranging from 9 to 22 mm, with 2, 3, or 4 holes. Ideal for mass production of garments such as workwear, specialized uniforms, and military apparel, this machine offers high performance and exceptional reliability thanks to its advanced features and integrated direct drive servo motor.
The machine's automatic functions include button feeding, thread trimming with a short tail after cutting, and presser foot lifting, thus simplifying operation and increasing productivity. The 50 built-in sewing programs allow choosing among different sewing configurations, such as II and X, with the possibility to create new programs to meet specific production needs.
The button feeding system has a storage reservoir, significantly improving efficiency by reducing interruptions to reload buttons. The machine also features LED lighting for better visibility of the sewing area and an integrated USB port for easy program management and updates.
The integrated servo motor offers optimal power while being energy efficient, and the dry head design eliminates the need for lubrication of the needle bar, thereby reducing maintenance costs and fabric contamination risks. The machine requires connection to an air compressor for operating pneumatic components.
