Industrial automatic lockstitch sewing machine with an integrated servo motor and compound feed. Designed for a wide range of fabrics, from thin to extra-heavy.
The JACK H7-C replaced the previous JACK H6-CZ-4 model. The new machine has the Smart Stitching System: Flexible Alternation Technology and O Resistance Thread Control Technology. It sews thin fabrics without wrinkles and gives neat, bead-free seams on thick materials.
The machine sews upholstery fabrics, leather, faux leather, canvas, sailcloth, denim and other materials that need more force to pierce and feed. The walking foot feeds the fabric steadily, giving a high-quality seam.
It is used in the furniture industry, for sewing car interiors, and in the manufacture of tents, sports equipment and leisure goods. The stitch length is up to 8 mm, so thick items look better.
Automatic functions
The machine automatically trims the threads, lifts the presser foot, stops the needle in the set position and sews a backtack at the start and end of the seam. Functions are set on the control panel. The integrated servo motor works without a belt drive.
Smart Stitching System
Flexible Alternation Technology
An ultra-wide 1.3–5.5 mm alternation range makes the machine suitable for both thin and thick fabrics. The integrated 10.5 Nm torque gives a rapid response and precise fabric feeding.
O Resistance Thread Control Technology
30% less thread passing resistance and 20% better loop stability. Thread tension stays stable and the stitches look even.
According to the manufacturer, overall work efficiency increases by more than 9%.
