Abstract

In a paper making machine, transfer apparatus for guiding a paper web from the press section to the drying section includes a smoothing press including upper and lower smoothing press rolls wherein the web is passed from the press section to the smoothing nip either directly or guided by a guide roll. The lower smoothing press roll of the smoothing press is substantially situated at a position which is normally occupied by a so-called baby or lead-in cylinder of a conventional drying section and the drying wire of the drying section is guided over a sector of the lower smoothing roll which is of a size sufficiently large that the web is transferred onto the drying wire which then carries the web as a closed draw onto the first drying cylinder of the drying section and, preferably, to the subsequent drying cylinders as a so-called single-fabric draw.
