  3. 3. 1. Introduction (Finishing • Definition: – According to customer specifications, the paper is cut in reels or sheets and packaged • Purpose: – Eliminating imperfections – Dividing the paper into sales units – Protecting the paper against climatic conditions, moisture etc. – Marking the product with identifying labels • Configuration criteria – Sheets:  Web direction: long grain, short grain  Packaging: unreamed with or without counting strips, ream wrapped  Pallett: height, weight, sheets – Reels:  Width, diameter, core, weight tolerance3 Finishing Departement | Sappi Fine Paper Europe
  4. 4. 1.1. Finishing in the production process Finishing – making the paper ready for the customer Coater (+ calender) – paper improvement Paper machine – paper production (sheet formation) Stock preparation – mixing the raw materials, fillers, additives Collecting raw materials4 Finishing Departement | Sappi Fine Paper Europe
  5. 5. 1.2. Finishing installations • Overview – Calender (satination) – Slitter-rewinder – Reel packaging machine – Sheet & ream packaging machine Paper storage as an independent part of logistics • Paper improvement – Satination, just likecoating, can be part of the improvement process – Online calender as part of the paper machine Paper production Coating Satination Finishing Paper improvement5 Finishing Departement | Sappi Fine Paper Europe
  6. 6. 2. Calender • Purpose: – Making the paper smooth (mechanical process) and glossy (optical property)  Surface plasticizing • Method: – Physical processes – ironing effect - triggers  Pressure (mechanical)  Moisture exchange (hydrostatic)  Thermal force – administering heat - convection • Available components: – Heated steel rolls, unheated paper rolls – Heated steel rolls – unheated plastic rolls or rubber rolls • Impacting parameters: – Paper: temperature, humidity, surface mass, fibre material, fillers – Coating: humidity, temperature, mass, binding agents, pigments – Calender: roll temperature, roll roughness, roll surface, bending compensation, line force, nip pressure, number of nips, dwell time, velocity6 Finishing Departement | Sappi Fine Paper Europe
  7. 7. 2.1. Effect on paper properties • Advantages of calendering: – Enhanced smoothness, enhanced gloss – Decreased air permeability, decreased oil absorption • Disadvantages of calendering: – Increased density – Decreased thickness, stiffness, opacity, whiteness, rub resistance Base paper Coated paper + Calendered7 Finishing Departement | Sappi Fine Paper Europe
