Features:
1. Using high-performance servo motor to yarn guide, make the linear velocity reach over 800m/min, even reach 1800m/min, production efficiency will multiplied and reduce cost.
2. All-round intelligent control technology instead of mechanical structure, let machine performance reach the international advanced level, it's easy and convenient for operation.
3. Intelligent tension device, active unwinding device, automatic tracking overfeeding system, assure stabilization of shaping.
4. Yarn breaking device and length count device, use encoder to detect and control speed, promise the yarn produce consistency.
5. Using brushless motor driving, adjusting forming length and trimming angle intelligently, soft edge density is controllable, ensure yarn forming density uniformity.
