Abstract

There is provided a sheet manufacturing apparatus including: an accumulation section that accumulates a material containing fibers by an air flow to form a web; a transport section that transports the web in a first direction; a humidification section that humidifies the web; and a pressurization section that pressurizes the web humidified by the humidification section and compresses the web into a sheet shape, in which the humidification section includes an intake port that takes in air, a tank that stores water, a mist generation section that generates mist from the water, and an exhaust port that exhausts the mist and the air toward the web, and a position of the exhaust port is shifted in the first direction or a second direction opposite to the first direction with respect to a position of the tank.

Claims (24)

1 . A sheet manufacturing apparatus comprising:

an accumulation section that accumulates a material containing fibers by an air flow to form a web;

a transport section that transports the web in a first direction;

a humidification section that humidifies the web; and

a pressurization section that pressurizes the web humidified by the humidification section and compresses the web into a sheet shape, wherein

the humidification section includes

an intake port that takes in air,

a tank that stores water,

a mist generation section that generates mist from the water, and

an exhaust port that exhausts the mist and the air toward the web, and

a position of the exhaust port is shifted in the first direction or a second direction opposite to the first direction with respect to a position of the tank.

2 . The sheet manufacturing apparatus according to claim 1 , wherein

the humidification section has a duct which is provided between the tank and the exhaust port and through which the mist and the air pass.

3 . The sheet manufacturing apparatus according to claim 2 , wherein

the duct includes

a first duct provided above the tank and extending in the first direction or the second direction, and

a second duct provided between the first duct and the exhaust port and extending in a third direction intersecting the first direction or the second direction.

4 . The sheet manufacturing apparatus according to claim 3 , further comprising:

a tray positioned below the second duct.

5 . The sheet manufacturing apparatus according to claim 3 , wherein

the first direction and the second direction are horizontal directions, and the third direction is a vertical direction.

6 . The sheet manufacturing apparatus according to claim 1 , wherein

the humidification section is positioned below the transport section, and

the exhaust port is provided at a position facing the transport section from below.
