Abstract: A functional roll comprises a shaft body, a roll body, flanges, and bearings. The roll body is formed by stacking multiple module functional rolls. The module functional rolls are formed by stacking multiple nonwoven fabric sheets. The module functional rolls have a bore in which the shaft body is inserted. A module function roll is united.

Abstract: Conventional art has a structure consisting of a roll axis incorporating a structure of fine pores, and a roll unit provided around the outer circumference of a roll axis, wherein internal pressure of the roll axis is dispersed to the roll unit to make a fluid (gas-liquid) suction action, thus reducing the pressure loss and obtaining even distribution of the fluid (gas-liquid). As such, instead of a tubular roll axis, the structure of a roll axis is made fin-shaped or groove-shaped to maximize the action surface area that works on the inner pressure of the roll axis of the roll unit. However, other problems such as inefficiency of the fluid (gas-liquid) suction action and lack of mechanical strength of the roll axis remains.
