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.
A functional roll incorporating a lattice-shaped fluid (gas-liquid) guidepath structure comprising a tubular roll axis incorporating multiple fine pores, and a roll unit having a roll hole engaged with the roll axis, made of elastic non-woven sheet material or of high-density porous sheet material of a functional composite sheet material obtained by providing cross-linking elastic material onto the non-woven material, therein the roll unit comprises a lattice-shaped fluid (gas-liquid) guidepath structure to activate the internal pressure of the roll axis, the lattice-shaped fluid (gas-liquid) guidepath structure being formed by an internal pressure action space made of a cut-out portion which is provided on the circumferential area of the roll and in the axial direction of the roll unit as well as an internal pressure branching guidepath which is connected to the internal pressure action space and provided in the radial direction of the roll unit, made of a lower-density porous sheet material (compared with the aforementioned high-density porous sheet material) with a roll hole, made of elastic non-woven sheet material or of a functional composite sheet material, therein a cross-linking elastic body is provided on the non-woven material, that is characterized in activating internal pressure to the aforementioned roll unit through the lattice-shaped fluid (gas-liquid) guidepath structure.
