    • 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. To solve these problems, this invention provides a functional roll incorporating a structure of a lattice-shaped fluid (gas-liquid) guidepath made of high-density porous sheet material to activate the internal pressure of the roll axis, therein the structure of the lattice-shaped fluid (gas-liquid) guidepath, consisting of an internal pressure action space made of a cut-out portion provided on the circumference of the roll axis, and in the axis direction of the roll unit, and an internal pressure branching guidepath made of low-density porous sheet material, or a space communicating with the internal pressure action space, as well, being provided in the radial direction of the roll unit.
    • 传统技术具有包括细孔结构的辊轴和在辊轴的外周附近设置的辊单元的结构,其中辊轴的内压分散到辊单元以形成流体(气体 - 液体)抽吸作用,从而降低压力损失并获得流体(气液)的均匀分布。 这样,代替管状辊轴,轧辊轴线的结构被制成为翅片状或槽形,以使作用在辊单元的辊轴的内部压力上的作用表面积最大化。 然而,仍然存在诸如流体(气液)吸入作用的低效率和辊轴的机械强度不足等其它问题。 为了解决这些问题,本发明提供了一种功能性辊,其包括由高密度多孔片材制成的格状流体(气液)导轨的结构,以激活辊轴的内部压力,其中格子的结构 形状的流体(气液)导向路,由设置在辊轴的圆周上的切口部和辊单元的轴向的内部压力作用空间和内部分压导向路径构成, 的低密度多孔片材,或与内压作用空间连通的空间,也设置在辊单元的径向方向上。
