Additionally, the whole drying and hot air zone is operated in slight low-pressure so that no emission of leakage air is possible. The early headbox, more commonly called a flowbox or breastbox, consisted of a rectangular wooden vat that extended across the full width of the machine behind the Fourdrinier breast roll.

Additives Clay, fillers, dyes, sizing and other chemicals added to pulp to give the paper greater smoothness, color, fibered appearance or other desirable attributes. Chemically altered and dissolved in the kraft process, this material is removed from the pulp and becomes a valuable by-product.

The logs are sawn to shorter length, and the bolts are tumbled in large revolving drums to remove the bark. The sheets are pressed in a hydraulic press to a moisture content of about 50 percent, and the pressed sheets are formed into bales.How to Make Wood Pellets.
