Abstract:
The present invention suitably humidifies each of a web of an accumulated fibrillated material and a raw material that causes retention or adhesion as a result of the influence of electrostatic charging. A sheet production device (100) is provided with a coarse crushing unit (12) for coarsely crushing a raw material including fibers and a fibrillating unit (20) for fibrillating the coarsely crushed raw material in air. The sheet production device (100) is also provided with: first and second web-forming units (45), (70) that accumulate a fibrillated material obtained by fibrillation processing and form webs (W1), (W2); and a sheet-forming unit (80) that forms a sheet (S) from the second web (W2). The sheet production device (100) is additionally provided with a vaporization-type humidifying unit for humidifying the space in which the raw material is coarsely crushed in the coarse crushing unit (12) and a mist-type humidifying unit for humidifying the webs (W1), (W2) formed by the first and second web-forming units (45), (70).
