  3. Dryer I Type "S" • Avoids • Edge Flatter • Paper Wrinkles • Surface Defects • Gives • Contactless Drying • Uniform Moisture Content • Variable heat transfer • Fast Start Up

  4. Mini Cooling Section Meyerbar & Smoothing Roll Stand Gravure Rolls Intermediate Section

  5. Mini Cooling Zone • Floatation Nozzles • Lowers Web Temperatureprior to coating • Supports Web for 1 StageOperation

  6. Gravure Roll Coater • For Two Stage OperationLP Decorative Papers • Fixed MF Coating WeightIrrespective of raw paper coating • Independent to web tension • Gravure Rolls with defined “Nip” Size • Thousands of “Nips” over width of roll • Wet Coating 20 to 30 gsm on each Side varied by roll speed to paper

  7. Meyerbar & Smoothing Rolls • 2 Meyerbar rolls spread out coating ”Tyre Print” caused by gravure roll “Nips” over web width • 2 Smoothing Rolls Polish Product Surface Prior to Dryer II • Unit can be moved apart for cleaning & Gravure roll exchange

  8. Intermediate Section

  9. Dryer II Type "S" • Drives out moisture from core resin • Carries on the UF/MF core resin part curing • Drives out moisture from MF Surface Resin coating • Starts MF Resin part curing • Reduces moisture (volatiles) down to required final volatile content:5.8 to 6.5 % • Same dryer design as for stage I
