KF-9820-01

KRAFFT KF-9820-01 is a modern automatic buttonholer designed for precise buttonhole sewing on lightweight and medium-weight garments. The machine has an energy-saving servo motor built directly into the head (direct drive), and the individual mechanisms are controlled by stepping motors. This gives exceptional sewing accuracy and stable operation, and the machine can be quickly adapted to different types of buttonholes and materials.

The KF-9820-01 sews buttonholes with and without an eyelet end, with cutting before or after sewing, and with taper bartacks, straight bartacks or no bartack. With its programmable control panel, the length, width and type of buttonhole are easy to set, and sewing cycles for many different buttonhole types can be programmed without reconfiguring the machine.

The head body allows lengthwise buttonhole sewing on long garment parts, which makes the machine ideal for both short-run and mass production. Optionally, the KF-9820-01 can sew round eyelets 3, 4 or 5 mm in diameter, adding to its versatility.
