The initial dirt load in Fig. This was illustrated by the example of slot widths of 0. The results in better floatability. The trials showed that the additional flotation stages will only achieve the required efficiency when preceded by intensive mechanical treatment of the stock. After the welcome by the production and technical manager of the Hamburger Group, Harald Ganster, the guests had the opportunity to inspect the paper machine and obtain information on the successful start-up. In four trials the finished stock requirements were fully met. Rapid parent roll changing is ensured by unwinding with flying splice.

The employees of the Brazilian subsidiary had their celebration day too. They are all fitted with the Krieger InfraMatic system for perfect control of moisture cross-profile.

The required cleanness was not however fully achieved in one trial. For these sensitive screening tasks, the screens should be run at low consistencies, moderate rotor speeds and low pressure differences across the screen basket.

After excellent results with the Krieger infra-red dryers already operating for years on paper machines 1 and 2, the customer again chose Krieger equipment. In September, Voith celebrated 40 years of the Brazilian subsidiary company. Music and magicians provided a comfortable atmosphere, making the evening a unique and impressive event.

For the specialty grade calendar paper, conventional sizing is used on coater 1 instead of color, which is otherwise used only in film presses. To avoid mechanical overstressing of the fibres, the number of dispersion stages within a system should be limited to two. The different papers consist mainly of reinforcement pulp kraft pulp-long fiber , hardwood pulp such as e. Removal efficiency decreases with increasing shear and compression forces in the screen. The remaining increment in cleanness must be achieved using two additional flotation modules. Minimum slot widths of 0.
