This paper is desmibed the pressure characteristics of the transporting web handling roller with different permeabilities. In the experiments, for web of two types such as newspaper and PET film used. the pressure distribution of rotating guide roller is measured for using a pressure transducer for behavior combination of web wrap angle, web tension, web width and rotating roller speed. Moreover, velocity distribution between the web and rotating roller was measured in the inlet and outlet region by PIV. From the experimental results, the hydrodynamic behavior for two types of webs with different permeabilites are clarified. The vortexes generate in the inlet region and the reverse flow occurs in the outlet region. The change of pressure like spike was considered base on these phenomena
