The front, middle and back rollers are controlled by separate oil-bath gear reducers and independent servo motors. To change drafting processes, input parameters via HMI or remote data setting for easy and convenient operation. It lays a foundation for the subsequent transformation of a digitally-controlled factory.

With a vertical steel bank tray system, once the yarn reaches its full bobbin, bobbin pulling, placing and conveying can be done automatically instead of manual doffing. This reduces the labor intensity of workers, improves both doffing and production efficiency and increases the spinning profit rate.

The equipment features a user-friendly man-machine interface, ensuring straightforward operation and clear visual feedback. The new interface design minimizes operational complexity, allowing for efficient and intuitive control with minimal training.

3-roller compact kit has simple structure and wide application of spinning varieties. Compact spinning, siro-compact spinning and ring spinning can be switched on the same machine according to different processing requests.

This is a modification of the lifting system in the ring spinning frame, which simplifies the structure and increases the yarn reserve rate. After modification, the lifting process features digital operation, making it simple and convenient to operate.
