Abstract

A sheet manufacturing apparatus 1 includes an accumulation section 50 that forms a web W; a transport belt 621 that comes into contact with one surface of the web W to hold the web W and transports the web W; a suction section 200 that is provided above the transport belt 621 to cause the web W to be adsorbed to the transport belt 621; and a sheet forming section 70 that forms the sheet with the web W, in which the suction section 200 has a first duct 210, a second duct 220 provided downstream of the first duct 210 in the transport direction, and a third duct 230 provided downstream of the second duct 220 in the transport direction, and a plurality of third suction holes 239a and 239b are provided in a suction region 233 of the third duct 230, the suction region 233 includes a first region 233a and a second region 233b located downstream of the first region 233a in the transport direction, and the number of the third suction holes 239b provided in the second region 233b is smaller than the number of the third suction holes 239a provided in the first region 233a.

Claims4

Dependent claims

A sheet manufacturing apparatus that manufactures a sheet from a material containing a fiber, the sheet manufacturing apparatus comprising:

an accumulation section that accumulates the material by an airflow to form a web;
a transport belt that comes into contact with one surface of the web to hold the web and transports the web along a transport direction;
a suction section that is provided above the transport belt to cause the web to be adsorbed to the transport belt by suction;
and
a sheet forming section that forms the sheet by pressurizing the web, wherein
the suction section has a first duct, a second duct provided downstream of the first duct in the transport direction, and a third duct provided downstream of the second duct in the transport direction, and a plurality of suction holes for suctioning air are provided in a suction region of the third duct,
the suction region includes a first region and a second region located downstream of the first region in the transport direction, and
the number of the suction holes provided in the second region is smaller than the number of the suction holes provided in the first region.
