Model HMG4000-B Autocompnic Pirn Winding Machine is a kind of new weft winding equipment improved from Model HMG2000 and HMG3000. It is the most advanced in the preparatory industry of textile weaving and tatting to roll or wind the bobbin yarn into woof yarn for weaving. The machine is suitable for winding different yarns (silk threads) such as pure cotton, trueran, ramie, low elasticity filament, mid fibre, etc..
The machine adopts the latest numerical control technique and the most advanced automated equipment instead of the traditional mechanical transmission. Its core technique contains a supreme high scientific technology content. It is a revolutionary breakthrough in weft winding machine's manufacture technology, It breaks free from the conservative ideology of those so-called "designers" or "engineers". And it leads forward a tidal wave of reconstructing the preparatory equipment to make them automated.
This model's automatic control system is made and improved from the present Model 2000 by overcoming its many imperfections in hardware configuration and software programming. Mainly, it introduces and adopts the programmable digital movement logical controller, LCD Chinese displayer human-computer interface, stepping subdivided servo driver, and high-performance large-torque stepping motor.
