KF-3900

KRAFFT KF-3900 is a specialised industrial cushion quilting machine built for sewing cushions of different thicknesses and shapes. The machine can sew through very thick, plump cushions thanks to the pneumatically raised front part of the head and the high presser foot lift of up to 11.7 cm.

Clearance under the arm is 28 cm, which makes work on large pieces comfortable. The presser foot mounting mechanism is specially designed to enlarge the work area and allow precise stitching even on materials that are hard to sew.

KEY FEATURES:

• Pneumatic presser foot lifter: for work with thick cushions
• Electronic needle thread tension: high seam quality
• Direct-drive servo motor: energy-saving, mounted directly on the main shaft
• Create your own stitch patterns: up to 200 patterns, up to 20,000 stitches per pattern
• Easy pattern upload: via the USB port
• LED light for the work area: comfortable operation even in poor light

The machine lets you design and sew decorative tacks, which makes it the ideal solution for producing decorative and functional cushions.

The machine requires a compressed air supply to work correctly.
