Paper Producti on Process
General Statements Paper is made of wood fiber. The wood goes through several stages of process before it becomes a piece of paper.
Stage One To begin the process, trees are cut down from the forests. They are made into logs, and transported to the factory.
Stage Two At the factory, the logs are then passed through a debarker, where the bark is removed. After that, the bark-free logs go through chippers, where spinning blades cut the wood into two centimeter pieces. Those wood chips are then cooked with a mixture of water and chemicals. The result of this process is the pulp.
Stage Three In the next process, the pulp is washed, refined, cleaned and sometimes bleached, then turned to slush in the beater. Color dyes, coatings and other additives are mixed in, and the pulp slush is pumped onto a moving wire screen.
Stage Four As the pulp travels down the screen, water is drained away and recycled. The resulted crude paper sheet, or web, is squeezed between large rollers to remove most of the remaining water and ensure smoothness and uniform thickness. The semidry web is then run through heated dryer rollers to remove
Stage Five The finished paper is then wound into large rolls, which can be 9 meters wide and weigh close to 25 tons. Finally, a very sharp knife cuts the paper into smaller rolls, and the paper is ready for use.
