Abstract
The sheet manufacturing apparatus includes a fibrillating unit that fibrillates a raw material including fibers in a gas, an additive supply unit that supplies an additive, a mixing unit including a first rotating unit that mixes a fibrillated matter fibrillated by the fibrillating unit and the additive supplied by the additive supply unit, a depositing unit that deposits a mixture mixed by the mixing unit, a web forming unit including a mesh belt that transports a deposited material deposited by the depositing unit and a suction mechanism that sucks the deposited material to the mesh belt, and a control unit that changes granularity of a surface of the sheet by controlling at least one of a supply amount per unit time from the additive supply unit, a rotation velocity of the first rotating unit of the mixing unit, and a suction force of the suction mechanism.
