What you see in the photo above is not a roll of
commercial printing paper (a web) feeding into a heatset web press but a huge take-up roll of paper, winding up the custom printing stock as it is converted from a liquid pulp mixture into the dry, flat printing paper onto which presses will deposit ink. The Fourdrinier machine, as it is called, is almost as long as a football field. The paper pulp mixture travels through the machine on a wire mesh, and the water is allowed to drain off, yielding a flat, stable mesh of paper fibers suitable for commercial printing.
