Beater or Hollander
- introduced mid seventeenth century and superseded the method of preparing pulp
- by hammering or stamping
- the rags.
- process of reducing raw materials to a fibrous
- state in the production
- in a stamper
- it is a flat plate of iron in the bottom of the trough against which rags
- are pounded. In a Hollander
- it has ridges or knives and acts with the beater
- process of pressing to smooth or glaze
- a sheet
- of paper during the finishing
- - basic substance of paper manufacture derived
- from plant tissues
- - source of fibre
- for papermaking, usually in the form of linters
- or rags.
- The fibres are strong and flexible and suited to the production of fine papers.
- action of transferring sheets of newly formed paper from hand moulds
- to felt
- on a hand mould
- is the removable frame which retains the pulp
- on the cover
- while the water drains through. On a Fourdrinier
- machine, the deckle strap performs the same function on the moving wire
- slightly wavy line to the edge of handmade paper, formed by a slight
- thinning of the edge of the sheet by pulp
- creeping under the edge of the deckle
- during forming
- of the sheet.
- material woven from either cotton or wool with a raised surface which
- supports the wet sheet of paper during the stages of removal of water.
- the action of making a sheet of paper by dipping
- the mould
- into a vat
- of pulp,
- the water drains through the cover leaving the pulp on the surface
- name applied to the papermachine after the Fourdrinier brothers who
- financed its early development. It produces a continuous web
- of paper and was developed by Bryan Donkin from the original invention of
- Nicholas-Louis Robert.
- alignment of fibres
- in a sheet of paper caused by the flow of the web
- of wet paper in cylinder
- or Fourdrinier
- partially broken or beaten fibres
- for papermaking. See also Stuff
- unwanted part of woody plants, can cause
- degradation later in the life of the paper.
- rectangular wooden frame covered with either a laid or wove
- wire surface used for forming
- sheets of paper by hand.
- name for paper used for printing newspapers, the
- cheapest type made
- term applied to a pile of sheets, normally 144 but varying
- in number, of wet pulp, fresh from the mould,
- just made into paper couched
- with alternate felts
- and ready for pressing.
- the aqueous stuff
- containing disintegrated cellulose
- from which paper is made.
- formerly the principal raw material for making
- paper, now rarely used except for very high quality papers. Could be linen
- or cotton
- but by association also includes jute,
- sailcloth and hemp
- sideways movement of a hand mould
- by the vatman
- or the wire
- of a papermachine to interlock the fibres
- whilst still suspended in the pulp
- originally a solution of glue or gelatine
- but later any substance that reduces the rate at which paper absorbs water or
- ink. Can be applied by coating the finished sheet
- or by addition to the pulp
- before forming.
- See also tub-sized
- and engine-sized
process of treating the paper with size.
- originally the tank containing the stuff
- from which hand made paper was produced but later also applied to the tank in
- which the cylinder of a mould
- machine is partially immersed.
