GLOSSARY OF TERMS USED IN THIS REPORT
Given below are definitions of industry related terms used in the
text of this report.
Barker - A machine which removes the bark from pulpwood prior to
chipping or screening. Barkers include hydraulic, disk, and drum
Black Liquor - The intensely Black liquid residue from the pulp
washing process. The substance derives its name from its color and
is noncaustic but highly alkaline.
Broke Box - A box used for storage of broke, paper lost in the
papermaking process. Broke is normally recycled back into the
papermaking process, where it is used as pulp furnish.
Calender - A stack of horizontal chilled-iron rolls, resting
vertically on each other at a point near the end of the paper
machine. Paper is normally passed through the calender to improve
its smoothness or gloss. (See also supercalender.)
Chipper - A machine containing revolving disks with knives which is
used to cut pulpwood into chips of a size suitable for pulping.
Coater - A machine used to apply a mineral substance to paper which
is to be coated.
Couch – The point at which the newly formed paper web is couched, or
picked off the wire on which it is first formed and transferred to
the wet press felt for further dewatering.
Cylinder Machine - One of the two principal types of papermaking
machine (see fourdrinier) now primarily used to make paperboard.
These machines contain one or more wire-covered cylinders, or molds,
on which the paper web is formed. The cylinders May be immersed in
vats or receive the pulp from a headbox. The press section and dry
end of the machine are very similar to other paper machines.
Dandy Roll - A roll used to mark the sheet with a design imprinted
on the surface of the roll.
Digester – A cylindrical or spherical vessel used to treat pulp with
chemicals while under temperature and pressure. This process is
commonly described as "cooking" the pulp. Digesters May be of
either the batch type or continuous type.
Doctor Blade - A thin wood or metal scraper placed along the length
of a roll or cylinder to keep it free of pulp and paper residue.
Dry End - The section of the paper machine forward of the dryer
section, including the calender, and including the attached
equipment, not part of the fourdrinier, such as the reel and winder.
Dryer (also drier) - A series of steam-heated, gear-driven metal
cylinders, varying in number, and of 30 to 60 inch diameter each,
which are arranged in tiers. The wet paper sheet or paperboard are
dried as they pass over or under these cylinders. The section of
the paper machine containing the dryers is known as the dryer
Fourdrinier Machine - The principal type of machine on which paper
is made. It is named for its sponsors, the brothers Harry and Sealy
Fourdrinier. The fourdrinier contains four major sections, the wet
end, the press section, the dryer section, and the calender. A
detailed description of the fourdrinier machine appears in the text.
Fourdrinier Wire - The endless wire belt on which the paper web is
Grinder - A rotating, grooved grindstone (sometimes called a
pulpstone) against which logs are pressed and reduced to pulp. The
grinder is used to make mechanical pulp or groundwood.
Headbox - A flow control chamber which receives the paper stock from
the stock preparation system and by use of baffles and other flow
control devices assures an even flow of the pulp mixture through a
slice onto the fourdrinier wire.
Jordan - The traditional type of pulp refiner, consisting of a
conical plug rotating in a conical shell.
Knotter - A screen, usually incorporated in fine paper Mills, which
follows the chipper and removes oversize or irregular chips, knots,
and shives prior to cooking in the digester.
Kraft Pulp (also sulfate pulp) - derived from a German word meaning
strong, kraft pulp is produced by a process in which the cooking
agent is a mixture of sodium hydroxide and sodium sulfide.
Machine Clothing - The fourdrinier wire and felts of a paper
machine. Strapping and other parts May also be included.
Mechanical Pulp - Any woodpulp manufactured in whole or in part by a
mechanical process, including groundwood pulp, chip mechanical pulp,
thermomechanical pulp (TMP), chemithermomechanical pulp (CTMP), and
bleached chemimechanical pulp (BCTMP). (see grinder.)
Nip - The line or point of contact between two rolls such as the
press rolls and the calender rolls.
