So far, press shoes were pressed evenly over the width or with lower pressure at the edges.
  • the contour of a Yankee drying cylinder of a tissue machine is changing as a result of the vapor pressure in the interior and by a thermal expansion of the frontal ceiling. If a press shoe is then pressed against the Yankee cylinder to form a press nip, the pressure pressure profile in the transverse direction is no longer constant, but it deviates upwards or downwards at the edges. The deviations are not always constant, but depend on the operating parameters, e.g. the basis weight, the speed, the vapor pressure, the temperature, the line force of the press nip and / or the like. The line force can, as is known, be calculated from the compression pressure profile and the nip geometry. There is a clear connection for the same press shoe.
