PROBLEM TO BE SOLVED: To make a supply amount of a raw material constant to suppress fluctuation of sheet thickness.SOLUTION: A sheet manufacturing apparatus has: a supply part which supplies single sheet of a raw material including fiber; a coarsely pulverizing part which coarsely pulverizes the raw material including fiber supplied from the supply part into coarsely pulverized pieces; a defibrating part which defibrates the coarsely pulverized pieces into a defibrated product; a forming part which forms sheet by using at least a part of the defibrated product; a cutting part which cuts the sheet; and a conveyance part which conveys an end material of the sheet cut by the cutting part to the coarsely pulverizing part or the defibrating part. In the case where the conveyance part conveys the end material to the coarsely pulverizing part or the defibrating part, a supply interval of the raw material by the supply part is made longer.SELECTED DRAWING: Figure 2 |
