摘要： Provided is technology improving the efficiency (productivity) of a sheet manufacturing apparatus. A sheet manufacturing apparatus 100 manufactures sheets S by heating with heaters 81 and 82 a mixture (second web W2) of resin and fiber produced by defibrating feedstock MA. The heaters 81 and 82 each have a first roller 171, a second roller 172 that holds the second web W2 with the first roller 171, and a moving mechanism 190. The moving mechanism 190 can switch the first roller 171 and second roller 172 to a position holding the second web W2, and a first roller 171 and second roller 172 are separated and do not hold the second web W2. The heaters 81 and 82 are configured as units that can removably installed to the sheet manufacturing apparatus 100.

摘要： A web manufacturing apparatus includes a transport section configured to transport a web containing fiber, a web humidifier configured to humidify the web, and a control section configured to control operation of the transport section and the web humidifier. When transportation of the web by the transport section is stopped, the control section causes the transport section to recommence transportation of the web after the web is humidified by the web humidifier. The control section may also cause the web humidifier to stop humidification of the web after the web humidifier starts humidification of the web and a predetermined duration elapses.

摘要： 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.
