  • Patent number: 11384482
    Abstract: 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.
