    Abstract

    In the papermaking process it is a well-known fact that the flow condition of a free jet entering the former section has a direct influence on the structure of the final paper. In this paper we present a systematic analysis how surface roughness and MD characteristic size of the slice jet depend on jet velocity, jet length, pulp consistency and vane geometry. The measurements are based on laser profiling and ccd-imaging.
