Winder upgrade by Voith: 15 percent increase in capacity thanks to SmoothRun damping bearing system
- Higher operating speeds
- Improved winding results
- Reduced maintenance costs
In conventional winders without special damping, vibrations can occur at higher production speeds for certain paper grades, and these vibrations can impair winding quality. To minimize the disruptive effect of vibrations during the winding process, the production speed and accelerations rates are reduced below the maximum capability of the winder. The solution: With SmoothRun hydropneumatic damping bearings from Voith the vibrations can be effectively reduced even at high speeds, allowing the equipment to operate at consistently high production speeds. At the same time, SmoothRun improves the winding results and reduces the overall mechanical stress on the machine.
Papier- und Kartonfabrik Varel (PKV) based in Lower Saxony, produces high-quality corrugating medium and testliner on its PM 5. Until now, the existing VariFlex M had to be run at a lower speed when producing paper grades sensitive to vibrations. The result is the winder could barely keep up with the production of the paper machine.
The purpose of the hydropneumatic damping bearings was to allow the winder to be operated at the maximum speed. “Following commissioning of the new bearing system we were able to reduce vibrations for all paper grades and increase speeds. We are currently optimizing the settings of the bearing system with intensive support from Voith,” explains Michael Wolff, Line Manager Equipment at PK Varel. “Following this optimization phase we assume that the speed of the winder can be increased. While further enhancements together with Voith are being made the winder can keep pace with the production of the PM 5,” says Wolff. Voith is helping the company achieve this goal by providing intensive support, e.g. by performing vibration measurements.
