摘要

The fabric web (7) such as paper-, cardboard-, tissue or other material web comprises a first smoothed layer (16.1), a second layer (16.2) and a third smoothed layer, where the first layer has higher density than the second layer, the third layer has higher density than the second layer and the first and second layers have same composition.
