Web manufacturing apparatus and sheet manufacturing apparatus
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.
1. An apparatus for use in web manufacturing, the apparatus comprising:
a belt configured to transport a web containing fiber;
a web humidifier configured to humidify the web; and
a controller configured to, in order,
stop the belt,
cause the web humidifier to humidify the web, and
start the belt.
2. The apparatus for use in web manufacturing according to claim 1 , wherein the controller is configured to cause the web humidifier to stop humidification of the web after the web humidifier starts humidification of the web and a predetermined duration elapses.
3. The apparatus for use in web manufacturing according to claim 1 , further comprising
a first humidity sensor configured to detect humidity in a space in which the web is transported, wherein
the controller is configured to control operation of the web humidifier based on a detection result of the first humidity sensor.
4. The apparatus for use in web manufacturing according to claim 3 , wherein the controller is configured to cause the web humidifier to humidify the web when the humidity detected by the first humidity sensor is a predetermined value or below.
5. The apparatus for use in web manufacturing according to claim 1 , further comprising
a second humidity sensor configured to detect atmospheric humidity, wherein
the controller is configured to control operation of the web humidifier based on a detection result of the second humidity sensor.
6. The apparatus for use in web manufacturing according to claim 1 , wherein the web humidifier includes a vaporizing humidifier device.
7. The apparatus for use in web manufacturing according to claim 1 , wherein the web humidifier is configured to humidify the web at a temperature at which a dew point of a space in which the web is transported does not exceed an atmospheric temperature.
8. A sheet manufacturing apparatus configured to manufacture a sheet from a web which is pressed, the sheet manufacturing apparatus comprising:
the apparatus for use in web manufacturing according to claim 1 ; and
a press configured to press the web humidified by the web humidifier.
9. The sheet manufacturing apparatus according to claim 8 , wherein the web humidifier is configured to humidify the web at least positioned between the belt and the press.
