How is paper made?
1. Woodfibre arrives at the paper mill as whole tree trunks
2. At the paper mill, the logs are debarked and and put through a chipper which reduces the logs to wood chips
3. A digester cooks the wood chips in chemicals and blow tank reduces the wood chips to fibres (wood pulp)
4. The wood fibres are then washed to remove impurities and screened to remove any knots or splinters
5. The wood fibre is then put through a bleaching process to whiten the pulp
6. The pulp is beaten, refined and additives are added
7. A head box stores and meters pulp onto the wire. Paper is formed on the wire where press rollers remove excess water
8. The paper is then put through a drying machine to dry the paper sheets
9. The paper is wound onto large rolls and then a slitter cuts the rolls into smaller rolls
10. Finally a sheet cutter cuts the paper rolls into sheets.
