Advantages:
1. Shaftless printing cylinders.
2. Central industrial computer control with bus linked to PLC and with 7 motors.
3. 4-sectioanl floating roller system for tension control.
4. Pre-driving for unwinding and automatic film splicing and connection.
5. Conic winding tension control.
6. Pneumatic conic loading and unloading.
Features:
1. The central computer employed a color monitor for touch screen operation and top control software. In fixed period displays performance and production parameters. Industrial computer give synchronous control of all unwinder, rewinder and all guide rollers speed.
2. Employed an automatic registration controller. Stable, reliable and easy to operate. The registration and checking sensors have high resolution and very sensitive, widely fits most materials.
3. Overprint system realized automatic substrate alignment: Auto initial alignment -- slow memory alignment -- high speed alignment.
4. Unwinder control system includes AC motors, low frictional cylinders, tension sensor and V.F. drive, etc. And they are controlled by the computer. It realized synchronous tension and speed and it is with functions of web exchange pre-driving and automatic high speed splicing.
5. The infeed and outfeed control system includes AC motors, none frictional cylinders, tension sensors, closed loop of vector V.F drives.
6. Rewinder control system includes AC motors, tension sensors and V.F drives. It has a synchronous speed, tension and conic software system. Pre drive for web exchange and high speed splice.
