Abstract
A sheet manufacturing apparatus has a heating/compressing unit configured to form a sheet by heating and compressing material including fiber and resin, and the heating/compressing unit includes a first rotating body that rotates, and a second rotating body that rotates in contact with the first rotating body. The sheet manufacturing apparatus holds, heats, and compresses material by the first rotating body and the second rotating body. The sheet manufacturing apparatus includes a heating unit that heats the outside surface of at least one of the first rotating body and second rotating body.
Claims19
A sheet manufacturing apparatus having a heating/compressing unit configured to heat and compress material including fiber and resin and form a sheet,
- the heating/compressing unit including a first rotating body that rotates and has no heater inside of the first rotating body, and a second rotating body that rotates in contact with the first rotating body and has a heater inside of the second rotating body, the first rotating body having a thermal conductivity less than the second rotating body, a hardness of the first rotating body being less than a hardness of the second rotating body, a temperature of the first rotating body being greater than a temperature of the second rotating body when forming the sheet,
- the sheet manufacturing apparatus holding, heating, and compressing the material by the first rotating body and the second rotating body;
- and
- comprising a heating unit that heats the outside surface of the first rotating body and directly contacts the outside surface of the first rotating body,
- the sheet manufacturing apparatus comprising no heating unit that heats and directly contacts the outside surface of the second rotating body.
A sheet manufacturing apparatus configured to form a sheet by heating and compressing material containing fiber and resin, the sheet manufacturing apparatus comprising:
- a roller pair including a first roller that has no heater inside of the first roller, and a second roller that has a heater inside of the second roller and has greater thermal conductivity than the first roller for holding, heating, and compressing material by the first roller and second roller, a hardness of the first roller being less than a hardness of the second roller, a temperature of the first roller being greater than a temperature of the second roller when forming the sheet;
- a heating unit that heats the outside surface of the first roller and directly contacts the outside surface of the first roller;
- and
- a control unit that controls the temperature of the heating unit and is electrically connected to the roller pair and the heating unit,
- the sheet manufacturing apparatus comprising no heating unit that heats and directly contacts the outside surface of the second roller.
