ecycling process was profitable. It included
heating, steaming and mixing in natriumsulphate to
compensate for lost chemicals. The natriumsulphate
gave name to the Sulphate Pulp process used for paper
production at Klevfos as well as the characteristic
odour from the soda house chimney. This was indeed
one of the intangible qualities at Klevfos which had
a positive designation implying work, money and
happy husbands returning from work.
The cellulose pulp was transported via a chute to
Silhuset (filter house) for rinsing and filtering.
Hollenderiet
Then the cellulose pulp was run through a type of
grinding mill called Hollenderiet before being
processed into paper. The only paper ever produced
at Klevfos was Kraft paper, and glue was added to
make it strong and more resistant to moisture. Alum
was also added to make the glue react with the fibres,
and colours was added here, Victorian red, blue or
green.
Hollenderiet was considered the pivot point of the
entire paper-making process. If the grinding process
was not exact, then this would course problems for
the paper-making machine. Connected to this part of
the plant are an office and a small laboratory.
Paper-making machine
The paper-making machine consisted of four parts: a
wet part (perforated cloth), a pressure part, a drying
part and a rolling part. First the pulp was sent through
a rinsing process, and then sprayed out through
nozzles to ensure an even distribution of fibres across
the width of the paper-making machine. Excess water
was removed by running the pulp through a perforated
cloth. The pulp was then carefully transferred to a felt
section, and the felt protected the wet paper while it
was being pressed. The paper was then transferred to
a drying area. Large cylinders were filled with steam,
and the paper gradually dried as it was fed through the
cylinders. At the end of the drying process, the paper
was pressed to give it a smooth surface. Finally, the
paper was rolled onto steel cylinders. The paper rolls
were later re-rolled and cut according to order.

Sorting hall, cutting and packing
Some of the paper was cut in various sizes, rolled
into separate rolls weighing from 5 kg and up. Some
of the paper was cut in a special sheet cutter. Sorters
then sorted, counted and packaged the sheets into
bundles. The bundles were then stored on pallets
and lifted up onto the floor above, where they were
packed and labelled according to size, number and
quality.
Deterioration agents related to
Klevfos
Fire and loss is well taken care of at the museum with
fire detection and alarm systems. For many years
these areas of running a museum have been of prime
interest to the national authorities, who have offered
grants for the purpose of installing fire and burglar
alarm systems in museums.
The third deterioration agent mentioned is water.
This is a far more complicated agent. Riksantikvaren,
the architect company and everybody agrees that
the original procedure of leading water under the
building to the Francis turbines in the turbine hall
must come to an end. The initial idea of preserving
this important part of the living plant: the flow of
water and the sound stemming from this is a major
source of deterioration. In order to preserve the iron
beam underneath the floor, the exposure from the
current water stream will have to be eliminated. It
is very important to keep the drainage around the
Paper Mill in good order. The annual snow-melting
