Abstract

An apparatus includes: a defibrating unit that defibrates a material to turn it into fibers; a fiber piling-up unit that piles up the fibers to form a second web; a pressing portion that presses the second web to turn it into a sheet; and a humidifying mechanism that supplies humidified air to the fiber piling-up unit. The fiber piling-up unit includes a rotating portion that stirs the fibers supplied from the defibrating unit, a case in which the rotating portion is housed, and a mesh belt that is provided under the case and transports the second web in a transportation direction. The second web is formed on the mesh belt by piling up the fibers on the mesh belt. The humidifying mechanism includes a downstream-side nozzle that is provided downstream of the fiber piling-up unit in the transportation direction and supplies the humidified air to the fiber piling-up unit.
