Division, the Fiber Preparation Systems Division
was successful in winning orders for complete
stock preparation and approach systems or
major upgrades at Thüringer Hygiene Papier
and Procter & Gamble, Germany; Shandong
Hengan Paper, China; and ICT Iberica, Spain.
Also, Holmen Paper Peninsular, Spain; Al
Sindian Paper, Egypt; Shandong Huatai, China;
and Norske Skog Albury, Australia awarded
orders for paper machine approach systems to
the Division.
Research and Development
The success of a recycled fiberline or stock
preparation system is based on the right integration
of sub-processes such as pulping, screening,
cleaning, flotation, dispersion, bleaching, and refining.
It is important to have a pilot plant to run trials
– upon customer request and for internal product
development. A major investment by the Division
in 2004 was the extension of the pilot plant in Graz,
Austria so that it can run full-line trials. The Division
is now able to offer full-line trials for all recycled
fiber and stock preparation sequences and comprehensive
testing of different process steps.
In addition to the pilot plant, the Division focused
its development activities on optimizing new products
(e.g. SelectaFlot flotation, CompaDis
dispersion, and Papillon LC refining).
Also, the Division was engaged in the complete

redevelopment of conventional equipment (such
as LC/HC pulpers to reduce energy consumption
and widen the operating window; and the
RotoWash “screen” which is now equipped with
electron beam drilled baskets for ash washing and
fiber recovery).
After extensive research in paper machine
approach systems, the new ShortFlow concept
was introduced. ShortFlow reduces space
requirements, lowers investment and operating
costs, and increases the flexibility of a paper,
board, or tissue machine.
Extensive development work is underway to
design a complete water handling system from the
paper machine back to the pulper.
