Mould (Papermaking)

In hand papermaking, a mould is a wooden frame similar to a window, with a mesh screen of brass, stainless steel or a synthetic fiber stretched across it. The papermaker submerges the mould in a vat of pulp, then lifts and drains it, forming a uniform coating of fiber on the screen that becomes a sheet of paper. A removable frame called a deckle is fitted onto the mould to contain the pulp during forming and give the sheet its edges.
