Abstract: A paper making apparatus includes a mould having a mesh screen and a deckle of comparable size. The deckle includes a shaped inner edge for directing pulp onto the screen. The mould and deckle are held together and dipped in a vat having a pulp and water slurry to form a sheet of paper. The mould and deckle are constructed of materials that will not warp, crack, twist, or otherwise deform from repeated use in water. The mould also includes structural ribs to hold its shape. An alternative embodiment of the invention includes a mould having a mesh screen and structural support ribs and a deckle box having a shaped inner lip and a sealing means attached to the lip. The combination of mould and deckle box may be dipped in water and does not require the presence of a vat having a pulp stock. Pulp may be poured into the mould and deckle box assembly. The mould and deckle box are constructed of materials that will not warp, crack, twist, or otherwise deform under normal use in water.
