III.  Major configuration
The Controlling System

1. The operator can preset printing numbers on the auto-counter and the machine will stop at the preset number.
2. The machine will stop at non-feeding. 
3. Tension Control System;Register color by manual

Unwind and rewind 

1. Machine should have one unwind and  rewind
2. Material holder use air shaft
3. Unwind with auto deviation correction system (EPC)
4. Powder brakes for unwind system
5. Powder coupling for rewind system; MOTOR CONTROL

Printing

1. Low speed and full load startup; stable running by tension control when increasing and decreasing speed; noise is decreased
2. Aluminum roller adopts the Japan semi-sealing small bearing; flinty oxidation, static and dynamic balancing treatments are conducted; low resistance and small flop.
3. The special made modulus angular gears adopted; accurate printing size and full printing specifications (6.35mm is a spec)
4. Doctor blade system and circulating pump
5. The grouped and controlled bottom roller processed with Germany particular steel materials processed with special techniques and electrically gilded with 0.1mm hard chromium protective layers 
6. Quick good quality of ceramic anilox roller
7. The machine use hydraulic printing-roll loading system which can automatically load printing rolls and run inks after the machine alarm working signal.
8. Good quality printing
9. Brilliance color appearance.
10. The operation is easier and more convenient,the register is more accurate,and the lifespan is also longer
