Satoshi Wada and Kenji Kowata
Kurita Water Industries Ltd.
In recently years, various new types of contaminations are occurred
in the papermaking process, they decrease the productivity of papermaking.
Felt conditioner are applied for resolving these problems.
There are very few technical reports describe on the relation between
papermaking conditions and the variation of contamination, and their
treatments. Here, felt conditioners named "PRESS SHOT" series were
developed based on a new concept, and their applications were introduced
in this paper.
PRESS SHOT series were designed and developed for dealing various
kinds of the contamination in papermaking. They are especially effective
for decreasing the contamination by calcium carbonate, and increasing
the papermaking productivity.
It is believed that PRESS SHOT will match the increasing trend
of higher filler content using calcium carbonate.

Design Section, Kawanoe Zoki Co., Ltd.
Now two BTF automatic dilution system are running smoothly in
First installation is at Marusumi Paper PM3 in 2004, and second
one is at Ehime Paper PM2 in 2005. Those two installations have
achieved much better level of 2 sigma than the target value we
had expected. And we are starting up the third BTF dilution system
at M Paper PM4 in this August. Those three installations are BTF
dilution system retrofit to the existing headbox. BTF dilution
system retrofit is in some means to enhance the performance of
the existing headbox by replacing the tapered header with the BTF
Central Distributor and BTF dilution system.
The BTF retrofit mentioned above gives your headbox a new breath.
A complete new hydraulic headbox with BTF dilution system is in
our scope of supply. 60 BTF headboxes have already been installed
in Europe and 20 in North America.
Substantial improvements in CD profile, fiber orientation, and
formation have been achieved. And in Japan we are starting up a
new complete BTF headbox with automatic dilution system at M Paper
in the next January. We will soon be able to show the best result
of both third BTF retrofit to an existing headbox and a first complete
new BTF headbox.

Development of Healthy/Functional Crops
Forestry Science Laboratory, Nippon Paper Industries Co., Ltd.
We have developed the original technology to generate genetically
modified woody plants for pulp materials. For example, we produced
an anti-salt damage genetically modified eucalyptus into which
the gene of anti-salt bacteria was introduced. Although a lot of
genetically modified plants have been developed in all over the
world, the eucalyptus is one of the most difficult plant species.
We developed the original technology to generate a genetically
modified eucalyptus. This technology could be applied to produce
healthy/functional crops which healthy/functional materials, peptide
or protein, were accumulated into an edible part of plant. We mainly
introduce here genetically modified rice seeds for the prevention
of human cedar pollen allergy and type-II diabetes. These rice
seeds demonstrated the potential to induce biological effects in
cultured mouse cell systems. We will commercialize the rice seeds
in near future, following verification of efficacy and safety in
animals and human.

We have focused on adoption of pulp that is a recyclable material,
instead of plastic that is an exhaustible resource, and developed
"a paper bottle" in 2000 for the first time in the world
as an attempt to the recycling society in the future1〜2). In this development,
we found out that the pulp is a material with a great diversity
and can immobilize a functional powder at a high ratio3).
We have developed a ultra-thin and flexible heating sheet element
with abundant steam generation by immobilizing the iron powder
and the activated carbon on the pulp in a high density, applied
In this paper, we report this heating sheet element that is quite
different from a common heating element such as the body warmer.

A new, instantaneous full-sheet moisture profile measurement has
been after the press section. This new measurement system, called
IQInsight, takes instantaneous profiles of the moving paper using
an array of infrared detector modules across the web. This measurement
array and associated fiber optic cabling are embedded in a pressurized
protective enclosure that is located early in the first dryer section.
With this measurement, short-term machine direction and cross
direction disturbances that cannot otherwise be seen clearly with
dry end scanning measurement are isolated and quantified. Specific
examples of MD and CD stability problems that have been identified
and corrected are presented.
New Techniques for Paint and Coating Applications
Nihon SiberHegner K.K.
In practical applications the following information is important
concerning the rheological behavior of coatings:
・Time depending behaviors directly after a sudden change of shear
conditions. Practical use:
Application behavior (thixotropy), leveling,
sagging, layer thickness.
・Rheology plays an important role in dewatering processes. It
is therefore interesting to analyze
the dewatering process and
rheological behavior of a suspension simultaneously.
This paper informs newer rheological measurement about the behavior
paints and coatings. Presented is a new test method for the investigation
of the thixotropic behavior.

Paper Converting Machinery Sect., 2nd Machinery Dept., K.K. IRISU
Today's folio sheeting industry is facing a challenging situation.
The printing industry requires high quality paper and board material
to achieve high-quality printing results to satisfy their customers'
At the same time, paper mills and converters face high price and
cost pressure due to smaller order sizes and shorter time to delivery.
In this situation, marks and scratches on high-quality paper and
board mean insufficient product quality, less output, more waste,
lower efficiency and productivity of equipment and can result in
customer claims, loss of image and, at the worst, loss of future
E.C.H. Will has found the solution to avoid marking on the surface
of top quality paper and board, even at speeds of up to 350m/min.

Paper sludge (PS) has been discharged from paper-mill as an industrial waste
of paper manufacturing processes. Most of them has been burned in an incinerator
and thrown into the discard as solid waste for reclaiming a land. It is urgent
matter to establish an effective technique for a recycling of PS, in consideration
of current envirornment-oriented trend. In recent years, the formation of
zeolites using PS ash has been reported. Acetaldehyde (CH3CHO) is a kind of
toxic gas with strong fruity smell, and is contained such as in motor exhaust
and tobacco smoke. It is strongly required to develop agents for removing
toxic gases, in relation to current health-oriented trend. In this study,
we tried to synthesize three types of zeolites, NaP1 (P-TiO2), Zeolite A (A-TiO2)
and Faujasite (F-TiO2), from PS ash containing titanium dioxide, discharged
from paper mills in Shikokuchuo-shi. These zeolites were produced by hydrothermal
reaction with sodium hydroxide. The capacity of these formed zeolites containing
titanium dioxide was evaluated by removing acetaldehyde experiment. All formed
zeolites containing titanium dioxide had abilities for removing acetaldehyde
gas. In particularly, F-TiO2 showed the highest activity. It was suggested
that the zeolites synthesized using from PS ash would have enough ability
for the removal of toxic gas in atmospheric environment.
