oploopkast; stofoploopkast; stofoploop head box; breast box; flow box Explanation: see: https://www.google.co.uk/books/edition/Dictionary_of_the_Pri... ‘Dictionary of the Printing and Allied Industries’ (2nd Edition) In English (with definitions), French, German, Dutch, Spanish and Italian ################ 6898 head box; breast box; flow box — Tank in which the head or level of the papermaking stuff is regulated to provide uniform flow on the paper machine wire. — f bac m de tête; caisse f d’arrivée; tête f de machine — d Stoffauflaufkasten m; Stoffeinlauf m; Maschinenbütte f — n oploopkast fm; stofoploopkast fm; stofoploop m — e caja f de entrada; caja f de alimentación — i cassa f d’afflusso; serbatoio m a livello di carico regolato ==================== Deze wordt aan de pulp toegevoegd voordat de pulp in de oploopkast van de kartonmachine wordt ingebracht. eur-lex.europa.eu = Sizing is added to the pulp before the pulp is fed to the head box of the board machine. eur-lex.europa.eu (https://www.linguee.com/english-dutch/search?source=auto&que... ) -------------------------------------------------- Note added at 59 mins (2021-01-14 22:17:51 GMT) -------------------------------------------------- "Stofoploop Omschrijving: De stofoploop is het deel van de papiermachine waar de dunstof (vezelbrij) op de zeef wordt gespoten. Er wordt ook op gelet dat de verdeling van de vezelbrij over de zeef egaal is. De vezeldichtheid in water is in de stofoploop 0,5-1%." (https://papierpraat.nl/woordenboek/stofoploop/ ) ############## "The purpose of the headbox is create turbulence to keep the fibers from clumping together and to uniformly distribute the slurry across the width of the wire. Wood fibers have a tendency to attract one another, forming clumps, the effect being called flocculation. Flocculation is lessened by lowering consistency and or by agitating the slurry; however, de-flocculation becomes very difficult at much above 0.5% consistency. Minimizing the degree of flocculation when forming is important to physical properties of paper.[8][9] The consistency in the headbox is typically under 0.4% for most paper grades, with longer fibres requiring lower consistency than short fibres. Higher consistency causes more fibres to be oriented in the z direction, while lower consistency promotes fibre orientation in the x-y direction. Higher consistency promotes higher calliper (thickness) and stiffness, lower consistency promotes higher tensile and some other strength properties and also improves formation (uniformity).[8][9] Many sheet properties continue to improve down to below 0.1% consistency; however, this is an impractical amount of water to handle. (Most paper machine run a higher headbox consistency than optimum because they have been sped up over time without replacing the fan pump and headbox. There is also an economic trade off with high pumping costs for lower consistency)."
