A fiber assembly-forming method includes forming a web containing a plurality of fibers charged to a first polarity on a transport belt charged to a second polarity opposite to the first polarity and applying a liquid to the web formed on the transport belt from a nozzle of a liquid coater. The liquid contains a binder binding the fibers.

Fiber assembly-forming method and fiber assembly-forming apparatus

A sheet manufacturing apparatus is an apparatus that heats a material containing fibers to form a sheet, and includes a heating portion that heats the material, and a control portion that controls a temperature at which the heating portion heats the material. The control portion sets a temperature of the heating portion to a first temperature in a first state where the sheet manufacturing apparatus manufactures the sheet, and sets the temperature of the heating portion to a second temperature lower than the first temperature at a predetermined timing in a second state where the sheet is not manufactured, or at a predetermined timing when a state of the sheet manufacturing apparatus is shifted to the state where the sheet is not manufactured.

Sheet manufacturing apparatus and control method of sheet manufacturing apparatus

A liquid absorber includes a liquid absorption member, a case, and a cover. The liquid absorption member absorbs liquid. The liquid absorption member includes a fiber and a liquid-absorbent resin. The liquid absorption member is stored in the case. The cover covers the liquid absorption member. The cover includes through-holes through which the liquid is to pass. The cover includes a recessed portion recessed toward the liquid absorption member. The recessed portion is disposed at a location to which the liquid is to be discharged. The through-holes are disposed at least in the recessed portion.
