Corrugated cardboard line Machine working principle

The paper roll fed by the mill roll stand. After heated and moisture adjusted by the pre-heater machine, core paper will go to the single facer, corrugated by roller, and gluing together with top paper to become single faced corrugated paperboard. Then conveyed through the bridge, pre-heated again by pre-heater machine, after glued by gluing machine, jointed by the double facer machine. And come out the corrugated cardboard board
The corrugated cardboard After slitting and scoring by thin blade slitter scorer and transverse cutting by NC cuter machine, corrugated board with different sizes are produced. Finally, these different size corrugating board will be stacked, calculated and then sent out by the stacker
