This paper describes the pressure characteristics of the transporting web handling roller with different types of permeability To be utilized in the experiment, two kinds of web, i.e. a newsprint and PET film were taken up. The pressure distribution of the rotating guide roller is measured to be offered for the use of a pressure transducer with a view to combining the behavior of the web wrap angle, web tension, web width, and rotating roller speed. In addition to the above, velocity distribution between the web and rotating roller was measured in the inlet and outlet region by PIV. From the experimental results, it is explained how the hydrodynamic behavior is with respect to the two types of web with different permeability. The vortexes are generated in the inlet region, whereas the reverse flow is produced in the outlet region. The spike-shaped change was in consideration based on these phenomena.
