Abstract
A method and apparatus for drying a traveling fibrous web such as paper including a hollow cylindrical dryer drum with means for directing a flow of steam into the drum and for removing condensate from the inside of the drum and positioning an axially elongate bristle support with bristles projecting radially outwardly so that the support and bristles form a brush of substantial uniform axial density to generate a visual high level of turbulence in the condensate and decrease the rotational speed of the layer of rimming condensate formed on the inner surface of the drum shell.
