Abstract
Method and apparatus for compensating bending of a lip beam in a paper machine when papermaking pulp flowing through the slice formed with the lip beam causes loading upon a bottom surface of the top lip beam. The bending of the beam caused by the loading is compensated by bending the lip beam in the opposite direction, by creating a temperature difference in the lip beam between a top part and a bottom part of the same.
