SHEET MANUFACTURING APPARATUS AND SHEET MANUFACTURING METHOD |
| 摘要 |
This sheet manufacturing apparatus is provided with: a nozzle for extruding a heated resin sheet; a main roll with a surface on which microstructures are formed; a follower roll disposed at a distance from the main roll; and an electricity-supplying mechanism. The electricity-supplying mechanism heats an electrically conductive section of the main roll by supplying electricity to the electrically conductive section from both edges of the main roll. |

1. A sheet manufacturing apparatus including a nozzle for extruding a heated resin sheet, a main roll including a surface portion with a microstructure formed therein, and a follower roll disposed at a distance from the main roll, the sheet being pressed between the main roll and the follower roll to transfer the microstructure to the sheet, the apparatus comprising:
a conductive portion in the surface portion; and a power supply mechanism that supplies power to the conductive portion from opposite ends of the main roll in order to make the conductive portion generate heat. |
