variable frequency, section drive3.Main EquipmentsPaper
Machine Wire SectionAt the wet end of the paper machine sits
the headbox, which distributes a uniform jet of watery stock. The
liquid falls onto the wire or forming fabric. Beneath the wire,
foils (short for hydrofoils) remove water and improve fibre
uniformity, ensuring that the fibres weave together in a tight mat.
The wire passes over suction boxes that vacuum out the water,
leaving a soft mat of pulp that forms the paper sheet, also known
as the paper web. By now the wire has travelled 30-40 meters. In a
couple of seconds, the water content has dropped to 75-80%, and the
web has lost its wet sheen.Paper Machine Press SectionThe next
stage of water removal consists of passing the paper web through a
series of nip rollers that squeeze the water out of the pulp mat.
This pressure also compresses the fibres so they intertwine to form
a dense, smooth sheet. At this stage, the water content has reduced
to between 45 and 55%.Paper Machine Drying SectionThe paper web now
travels through an enclosed space containing a number of
steam-heated drying cylinders. They are warmed up to 130ºC using
steam heat to ensure that the paper is now 80 to 85% dry. Wet
sizing solution is now applied to the paper in order to add a thin
layer of starch to the surface. Starch contributes to stiffness and
the bonding of the fibres within the sheet of paper. After the
sizing is applied, the paper passes through another set of heated
drying cylinders. In all, the paper web may travel 400 meters
through the dry end. In the process, it will lose roughly 93% of
its water.Paper Machine FinishingTo give the containerboard a
smooth and glossy surface to optimise it for printing, the paper
passes through a set of smooth rollers, which can be hard or soft,
that press the paper, embossing a smooth face on the paper
surface.Paper Machine WindingAfter completing its 500-metre
journey, the paper exits from the paper machine and is
automatically wound onto a jumbo reel, which can weigh 50 tonnes
and be up to eleven metres wide. The jumbo reel is lifted by crane
to a nearby winder, where the paper is unwound and cut into smaller
rolls as required by the customer.4. Finished productsPaper is
sorted into different grades such as waste paper, old carton box,
reed, wheat straw, bamboo, bagasse, newspapers, duplex, white
cutting, boards, core pipes, etc suitable for manufacturing
