Abstract:
Provided is a sheet manufacturing device with which it is possible to adjust the textured feel (graininess) of the external appearance of the sheet and to manufacture a sheet with a given textured feel. A sheet manufacturing device including: a defibration unit that performs in-air defibration of raw material containing fibers; an additive supply unit that supplies an additive; a mixing unit provided with a first rotation unit that mixes the defibrated material defibrated by the defibration unit and the additive supplied by the additive supply unit; a depositing unit that deposits the mixture mixed by the mixing unit; and a web formation unit comprising a mesh belt that carries the deposit deposited by the depositing unit, and a suction mechanism for aspirating the deposit toward the mesh belt. The sheet manufacturing device has a control unit that controls at least one of the supply amount of the additive supply unit per unit of time, the rotation speed of the first rotation unit of the mixing unit, and the aspiration force of the suction mechanism, and changes the granularity of the surface of the sheet.
