Abstract (en)
[origin: EP3604655A1] When a sheet is manufactured, a basis weight distribution in the sheet is appropriately controlled.A sheet manufacturing apparatus includes a drum unit 61 having a plurality of openings 61a, a web forming unit that has a deposition surface 72a, on which material containing fibers that has passed through the openings 61a is deposited, and forms a second web W2 on the deposition surface 72a, a sheet forming unit that processes the second web W2 and forms a sheet, and a control unit that controls a basis weight of the second web W2 deposited on the deposition surface 72a in a direction crossing a transport direction of the second web W2.
