The necessary immersion needs care and attention. The paper worker dips into the thick liquid, creating a wave motion in order to tangle the fibres. After a brief draining, the paper worker can remove the ‘cover': the sheet has taken shape. Another paper worker now takes over for the next stage of production. The mould is turned over and the sheet which comes out is placed on a felt carpet. This produces a pile of 100 to 250 sheets with a layer of felt between each one. This pile known as the ‘porse' (an old-fashioned term describing a wad of about 250 sheets or the ‘press load') then goes under the press. Vallis Clausa still has an old fashioned press which was operated by a capstan and needed 4 men to make it work, but today they prefer to use a much safer and more efficient hydraulic press which gets rid of 40-60% of water.
