Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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.
