Variation in the thickness of accumulated material is suppressed when material containing fiber is dispersed by the sieve and accumulated. A sheet manufacturing apparatus includes a drum that sieves defibrated material containing fiber, a first web former that accumulates first screened material discharged from the drum, and a processor that processes a first web accumulated in the first web former. During processing by the processor, the mesh belt operates at a first speed. When operation starts with the drum not operating, a startup operation including the mesh belt operating at a higher speed than the first speed in a first period after the drum starts is executed.

Fiber processing device, fibrous feedstock recycling device, and control method of a fiber processing device

A web manufacturing apparatus includes a defibration section that includes a rotating blade and is configured to defibrate a material containing fiber, a detection section configured to detect an electric charge amount of a defibrated material obtained by the defibration section, and a control section configured to control operation of the defibration section. The control section includes a first mode in which a revolution speed of the rotating blade is set based on a detection result of the detection section.
