2 ply corrugated cardboard production line is also named single face corrugated cardboard production line.
Old type of 2 ply corrugated cardboard line
In traditional consideration, the 2 ply corrugated paperboard production line is a simple line, it normally just is a single facer group, includes 3 machines, they are 1 single facer, 1 mill roll stand and 1 sheet cutter. Its speed is only 60m/minute.
Because its high consumption, low technical, the single face corrugator line is only popular in the small specifications, low grade carton producing plant.
Developing trend of 2 ply corrugator line
In line with the corrugated carton line develop to high technical, 2 layer corrugator line is also influenced, old machines have to be eventually be eliminated.
With the single face corrugated cardboard market is increasing day by day, low capacity of 2 layer corrugated paperboard production line can not meet the inquire of the market.
As per the situation of the market, we have to have a new design to update the single face corrugated cardboard production line. So we consider, what limit the speed of the 2 corrugator line? Single facer we have higher speed model, mill roll stand, we also have higher speed and heavy type model, just the sheet cutter, even NC sheet cutter, its speed is only 80m/minute, so if a new type of sheet cutter can solve the problem.
And then we designed and produced the new type sheet cutter, we call it NC slitter cutter, its design speed is 180m/minute, has same function with sheet cutter, it can slitting and cutting off the single face corrugated cardboard.
Sure, high speed cutter need to equip high speed stacker, so we equip the lift type stacker with the NC slitter cutter. For complete 2 ply corrugated cardboard production line running speed can reach to 180m/minute, we also add 2 sets of pre heater and a conveyor bridge in the line.
Our new technical 2 layer production line
Now our 2 ply corrugated line width can reach to 2500mm, and speed can be 180m/minute. Our new technical 2 layer corrugator line is popular in China Market and Europe Market.
It can also equip with auto splicer, logistic and conveyor system, produce management system, for the area and country which are high labor cost, this is a good option.
This corrugated line is the our first 2 ply corrugated production line in width 2500mm, after installation and testing to produce, it has been successfully accepted by the client. By now, it has worked more than 8 years, still keep steady working, good quality cardboard, low consumption.
