Abstract
A sheet manufacturing apparatus includes a defibrating unit configured to defibrate material containing fibers in the air, a classifying unit configured to classify by airflow defibrated material, which has been defibrated at the defibrating unit, into fiber material and waste material, a deposition unit configured to deposit the fiber material to create deposited material, a discharge blower configured to discharge the waste material by airflow from the classifying unit such that the waste material does not move toward a side of the deposition unit, a transfer blower configured to transfer by airflow the fiber material from the classifying unit to the deposition unit, and a forming unit configured to form a sheet by using the deposited material. When manufacturing by the sheet manufacturing apparatus starts, the discharge blower is driven before the transfer blower.
