Abstract: A method of controlling a sheet manufacturing apparatus is applied to a sheet manufacturing apparatus including a defibrating portion, an accumulating portion that forms web, a second transporting portion that includes a transporting belt to transport the web, and a pressing portion that includes a pair of pressing rollers formed from a first roller and a second roller and forms a strip-shaped sheet by pressing the web. The method includes a first step of transporting the web with the transporting belt, a second step of peeling a tip end of the web off the transporting belt, a third step of bending the tip end of the web by rotating the first roller in a first direction, and a fourth step of folding the tip end of the web by rotating the first roller in a second direction and passing the web between the pair of pressing rollers.
