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 humidification section that applies moisture from one surface side of the web; and a pressurization section that pressurizes the humidified web at a pressurization location to form a sheet, in which the pressurization section includes a first roller that comes into contact with one surface of the web at the pressurization location and a second roller that comes into contact with the other surface of the web at the pressurization location, the web is transported such that the one surface of the web comes into contact with a surface of the first roller over a predetermined length starting from the pressurization location, and the first roller has a heating mechanism, and the first roller heats the web while the one surface of the web is in contact with the surface of the first roller.

Claims

exact text as granted — not AI-modified
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 humidification section that applies moisture from one surface side of the web; and   a pressurization section that pressurizes the humidified web at a pressurization location to form a sheet, wherein   the pressurization section includes a first roller that comes into contact with one surface of the web at the pressurization location and a second roller that comes into contact with the other surface of the web at the pressurization location,   the web is transported such that the one surface of the web comes into contact with a surface of the first roller over a predetermined length starting from the pressurization location, and   the first roller has a heating mechanism, and the first roller heats the web while the one surface of the web is in contact with the surface of the first roller.   
     
     
         2 . The sheet manufacturing apparatus according to  claim 1 , wherein
 the first roller is made of metal.   
     
     
         3 . The sheet manufacturing apparatus according to  claim 1 , wherein
 a diameter of the first roller is larger than a diameter of the second roller.   
     
     
         4 . The sheet manufacturing apparatus according to  claim 1 , further comprising:
 a third roller provided at a position facing the first roller and downstream of the pressurization location in a transport direction of the web, wherein   the web peeled off from the first roller comes into contact with the third roller.   
     
     
         5 . The sheet manufacturing apparatus according to  claim 2 , wherein
 the surface of the first roller has irregularities.   
     
     
         6 . The sheet manufacturing apparatus according to  claim 1 , further comprising:
 a starch supply section that supplies starch for bonding the fibers; and   a mixing section that mixes the starch and the fiber.
