This machine has introduced advanced core technology from Germany and independently developed the latest variety. The casing is lengthened, the needle is 560mm away from the casing column, and the maximum sewing width is 802mm, with a wide range of applications. Adopting a linkage type feeding mechanism, it has good durability and balanced feeding, and can achieve consistent feeding volume for bulky sewing materials and medium thick sewing materials with high mobility during the sewing process. The use of built-in servo motors directly drives the machine, achieving fast start-up and precise braking; At the same time, advanced integrated computer control technology is adopted, with stable performance and strong anti-interference ability. Using a large rotary shuttle to reduce the number of bottom line changes and improve work efficiency; Adopting a fully automatic lubrication device to improve the service life of the machine. It has multiple intelligent sewing modes such as automatic needle positioning, automatic needle counting, automatic thread cutting, electronic thread clamping, and automatic foot lifting. Suitable for sewing medium thick materials, bags, leather jackets, leather products, etc.
