The
Paper Machine is a very large piece of machinery. A typical machine
is about the length of two football pitches and around 4 metres
wide. It can run up to speeds of 2000 m per minute - or 60 miles
per hour! The machine itself consists of 7 distinct sections.
The flow box, wire, press section, drier section, size press,
calendar and reeling up.
The
first section of the machine is called the 'Wet End'. This
is where the diluted stock first comes into contact with the
paper machine. It is poured onto the machine by the flow box
which is a collecting box for the dilute paper stock. A narrow
apperture running across the width of the box allows the stock
to flow onto the wire with the fibres distributed evenly over
the whole width of the paper machine.
The
machine is operated by computer control. The computer will monitor
the paper for moisture content, weight etc and computer screens
will show pictures of the process and should any adjustments need
to be made, an alarm will sound.
