ABSTRACT:
The invention relates to an apparatus for the generation of smoothness in paper. The paper (1) is thereby supplied to the rolls (2) of the smoothing mechanism with a moisture distribution which is characterized in that the moisture content in the inner layers of the paper is substantially smaller or at least as large as in the outer layers. This can be achieved with the aid of a dielectric paper web heating device (3) which is positioned in front of the rolls (2) of the smoothing mechanism. Through the invention less energy is to be required for the same smoothness values and a lower reduction in volume is to take place.
