How Paper Is Produced
1.Water is added to the pulp and other materials so the solution becomes evenly mixed.
2.Inside a large tub, the pulp is subjected to the effect of machine beaters. At this point, various filler materials are added to increase bonding between fibers.
3.The pulp is then poured from the head box onto a circulating copper/plastic wire mesh to be spread and interweaved evenly.
4.The wet paper will then be removed from the wire mesh to be placed between two rollers with cloth padding. The roller will squeeze the water out from the paper and the cloth will absorb and remove the moisture from the paper further. The paper quality will be improved and reinforced through squeezing, giving it a smoother surface.
5.Since the wet paper still contains up to 52~70% water content after squeezing, the excess water can no longer be removed through machinery at this stage. Therefore the wet paper is fed through a rolling surface with several vents of hot steam as a means of drying.
6.The paper will go through various machines for surface processing such as glue application and coating in order to improve the strength of the paper's surface.
7.After surface processing, more moisture will be present in the paper and therefore it needs to go through a secondary drying process.
8.The dry bolt of paper will go through a presser comprised of 218 rollers. The pressure between the roller surface and the paper will smooth the paper surface and give the paper a better luster.
9.The bolts of paper that have gone through folding and other related processes will be rolled up for cutting. The weight, quality and width of the paper will be inspected while it is being rolled up for adjustments to be made.
10.The original paper will then be cut into smaller rolls as the end product for further cutting.
11.The small rolls of paper will be cut into sheets of paper through the cutter.
12.Finally, the sheets of paper will be packed in kraft paper (usually in reams of 500 sheets).
