Slit device and sheet manufacturing apparatus

A slit device comprising:

• a first transport section which transports a web in a transport direction while nipping the web, the first transport section having a main upper member and a main lower member that nip the web;
• a second transport section which is disposed in parallel with a direction intersecting the transport direction of the first transport section and which transports the web in the transport direction while nipping the web, the second transport section having a sub upper member and a sub lower member that nip the web;
• a cutting section which is disposed between the first transport section and the second transport section in the direction intersecting the transport direction and which cuts the web along the transport direction;
• a first biasing member which biases the main upper member of the first transport section to the main lower member of the first transport section;
• and
• a second biasing member which biases the sub upper member of the second transport section to the sub lower member of the second transport section, wherein
• a cutting position at which the web is cut by the cutting section is a position within a nipping area where the main upper member and the main lower member of the first transport section nip the web along the transport direction, or is a position downstream of the nipping area in the transport direction, and
• a nipping pressure at which the web is nipped between the main upper member and the main lower member of the first transport section by the first biasing member is higher than a nipping pressure at which the web is nipped between the sub upper member and the sub lower member of the second transport section by the second biasing member.
