Abstract

A sheet manufacturing apparatus includes a second web forming unit that processes fibers into a web shape, a sheet forming unit that pinches and transports a second web processed into the web shape by the second web forming unit, and a control unit that controls at least any of a pressing state and a transport state in the sheet forming unit. The control unit causes the second web to pass through a nip unit by controlling at least any of a transport speed of the sheet forming unit, a nip pressure of the sheet forming unit, and a nip width of the sheet forming unit depending on a position of a leading edge of the second web with respect to the nip unit in which the sheet forming unit pinches the second web.
