摘要:
A functional roll (3) comprises a shaft body (300), a roll body (303), flanges (302), and bearings (301). The roll body (303) is formed by stacking multiple module functional rolls (X). The module functional rolls (X) are formed by stacking multiple nonwoven fabric sheets (7) and (8). The module functional rolls (X) have a bore in which the shaft body (300) is inserted. A module function roll (X) is united.
摘要:
A functional roll incorporating a lattice-shaped fluid (gas-liquid) guidepath structure (8) made of high-density porous sheet material (300) to activate the internal pressure of the roll axis (4), whereby the lattice-shaped fluid (gas-liquid) guidepath structure consists of an internal pressure action space (1) made of a cut-out portion provided on the circumference of the roll axis (4) in the axial direction of the roll unit, and an internal pressure branching guidepath (6) made of low-density porous sheet material (7), or a space communicating with the internal pressure action space, provided in the radial direction of the roll unit.
