the machine is with outside coating, used for carbonless copy paper and thermal paper, here is structure process:   

Unwinder----air blade or blade-----drying cabinests (three sections, almost 12m)----the back watering device( or  pastern)-----cylinders(three)-----cold water roller----- calender (press-polishing machine)---winder(auto skew adjustment)
