In the case of high-speed roller stands (> 1,500 m/min), vibrations can build up at the smoothing roll position due to the layer jump. This phenomenon is further intensified by the high energy input into the elastomer due to the high rotational speed and the high ambient temperature (T >120 °C).
As a result, no uniform line pressure can be maintained in the nip, causing air cushions between the layers and lateral alternating winding results.
The pulsating load on the smoothing roll leads to premature wear of the elastomer coating.
Problems in brief:
- Vibrations at the rewinder
- Uneven winding of the coil
- Air pockets between the layers
- Increased wear of the coating
