The continuous flexible thin materials such as news print, film, thin foil of metal, etc. are called web. This paper is described the pressure characteristics of the transporting web handling roller. In the experiments, for web of two types such as newsprint and PET film used. The pressure distribution of rotating guide roller is measured for using a pressure transducer for behavior combination of web width, web position and rotating roller speed. Moreover, velocity distribution between the web and rotating roller was measured in the inlet and outlet region by PIV. Air film thickness is measured for using a displacement sensor for behavior combination rotating roller speed. From the experimental results, the hydrodynamic behavior for two types of webs with different permeabilites is 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.
