Polymers, inorganic materials
Polymer sheet: Upper sheet → roller coating → (observation transition) → drying → cooling → lower sheet
Polymer coil: Unwinding → roller coating → Drying (IR or UV) → Cooling → winding
Inorganic sheet: Upper sheet → soil repair → drying → sanding → primer roller coating → Drying → sanding → Top paint roller coating → drying → Lower sheet
