Editing Paper machine (section)

=== Size Press ===
Additional [[sizing]] agents, including [[resin]]s, [[glue]], or [[starch]], can be added to the web to alter its characteristics. [[Sizing]] improves the paper's water resistance, decreases its ability to fuzz, reduces abrasiveness, and improves its printing properties and surface bond strength.  These may be applied at the wet (internal sizing) or on the dry end (surface sizing), or both. At the dry end sizing is usually applied with a ''size press''. The size press may be a roll applicator (flooded nip) or Nozzle applicator . It is usually placed before the last dryer section.  Some paper machines also make use of a 'coater' to apply a [[coated paper|coating]] of [[fillers]] such as [[calcium carbonate]] or [[china clay]] usually suspended in a binder of cooked starch and [[styrene-butadiene]] latex.  Coating produces a very smooth, bright surface with the highest printing qualities.
