How do you make paper out of rock?
Cilinders as high as tall buildings make sure there is enough room for the paper to rise up, until the right thickness (or thinness) is achieved. By pulling the paper up so high, it cools off at the same time. So when the paper cilinders have reached their highest point, the are pulled down again, and rolled up – ready for distribution!
