Abstract

267,107. Naamlooze Vennootschap Handelmaatschappij Fibra. March 5, 1926, [Convention date]. Pulp, preparation of.-In the manufacture of wood pulp from logs, boards, wood shavings, or wood waste, the raw material holding its natural moisture content is cut up or otherwise comminuted in a machine 1 then passed to centrifugal machines or disintegrators 2, where it is further subdivided. Broken fibres, sand, and other impurities are next separated in a sifting machine 3. Further subdivision into coarse bundles of fibres is next effected in a dry refiner 6 wherein heat is generated by friction, the natural moisture content being previously restored if desired in a chamber 5. Enough water to make a thick pulp is then added in a vat 7 and the pulp pumped to a wet refiner 9. Coarse material still present is separated bv a strainer 10 and returned to the vat 7, and the strained pulp passes to a drier in the form of a single cylinder machine 11, where it is sheeted, and it may afterwards be prepared for the market in a press 12. Alternatively, the refined pulp may pass direct to a beater and be made into paper, the drier 11 and press 12 then being dispensed with.
