Voith SpeedSizer AT means more speed for Smurfit Kappa's PM 6
- SpeedSizer AT extends the operating window for packaging paper production
- Reconditioning of existing Nipco deflection compensation rolls
- Smooth startup with new components
“The startup of the new SpeedSizer has shown how expertise and dedication bring about an excellent outcome. The project simply flew by,” says Jochem Meier, Manager Operations at Smurfit Kappa in Zülpich.
Smurfit Kappa wanted to achieve a higher production speed through its modernization of the PM 6 at the Zülpich mill. The company is one of the leading manufacturers of packaging in Europe. At its facility in Zülpich it produces premium quality testliner and recycled fluting in basis weights of 100 to 150 grams per square meter from 100 percent recovered paper.
Because the machine was only supposed to be shut down for a week for the conversion, detailed advance planning was absolutely essential for the success of the project. The excellent longstanding relationship between Voith and the customer facilitated this planning. For example, Voith’s service team had previously carried out maintenance on the PM 6 on an ongoing basis. However, the narrow time frame was just one of the challenges.
This is why Voith recommended installing a customized SpeedSizer AT with the existing Nipco deflection compensating roll system. This application system enables excellent coating and size profiles even at high speeds. Its use increases the operating window of the PM 6 and offers Smurfit Kappa more production flexibility. The SpeedSizer ensures an increase in the solids content of up to 17 percent and reduces the moisture ingress into the paper web. This results in a higher dry content downstream of the SpeedSizer AT, which helps substantially reduce drying energy and achieves much improved paper web running properties.
Voith used a Nipco roll that was already being used in the old puddle-type size press as a deflection compensation roll. Following comprehensive reconditioning, they now also ensure optimum CD profiles and consequently high paper quality in the new machine as well. The re-use of the previous rolls reduced the costs of the upgrade.
The use of the new UniFilm T applicator roll cover, which is very wear-resistant, ensures good metering rod service life and more efficient production. In the PM 6 they run for more than 400 hours, well above the average for comparable machines.
