Tape transcript:
Papermaking is a simle process. The procedure is almost the same as it was in 200 years ago. Look closely at this picture of an old papermaking machine. On the left is the pulp vat. Paper pulb was placed in the vat and mixed with a lot of water. The water was then drained and the pulp fibers were poured out of the vat and onto a conveyor belt. The conveyor belt took them under the rollers. There were quite a lot of rollers as you can see. Rhese rollers smoothed the fibers and pressed 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.
