What is the purpose of using a specificcylinder in vats?
Cylinders may be used in more than one vat to produce films of varying properties before further drying by pressure and heat.
How does a Vatman make paper?
To form the paper the vatman uses a wooden frame, covered by a wire screen of either a “woven” or “laid” pattern, called the “mold,” and a deckle. The deckle keeps the paper pulp from flowing over the edges of the mold. The exact method of forming paper varies with each vatman, but the basic operation is the same.
