Technical parameter:
Machine speed:220m/min
Effective breadth:1600mm,1800mm,2000mm,2200mm
Heating source:Steam

Characteristics:
1. Heating source of hotplate is steam, the temperature of every part is adjusted
   the valves which depend on the layers of corrugated paperboard and the speed.

2. Hydraulic pressure for up and down, subsection pressure according to the layers
   of corrugated  paperboard. Keeping suitable pressure is easy for the paperboard
   to form.

3. Pneumatic controls the tension of upper cotton belt, and imported automatic
   ballonet adjusts the moving of the upper and down cotton belt to keep the
   paperboard edge is in line with the belt.

4. Two pressure ways with weight roll or contact bar is optional,
   and the PLC controls the pressure. 

5. Frequency conversion motor drive the Double Facer.
