Papermaking is a simple process. The procedure is almost the same as it was 200 years ago. Look closely at this picture of an old papermaking machine. On the left is the pulp vat . Paper pulp was placed in the vat and mixed with a lot of water. The water was then drained and the pulp paper were poured out of the vat and onto the conveyor belt. The conveyor belt took them under the rollers. There were quite a lot of rollers as you can see . These rollers smoothed the fibers and press them dry. The finished paper was then put on a roll at the end. You can see the roll of paper at the far right of the picture.
