Abstract

A sheet manufacturing apparatus includes a web forming unit configured to form a web that includes fibers and a resin, a transferring unit configured to transfer the web that has been formed, a first cutting unit configured to cut the web in a direction intersecting with a transfer direction of the web being transferred, and a heating unit having a first roller configured to heat the web that has been cut.

First claim

What is claimed is:

1. A sheet manufacturing apparatus, comprising:
a web forming unit configured to form a web that includes fibers and a resin;
a transferring unit configured to transfer the web that has been formed;
a first cutting unit configured to cut the web in a direction intersecting with a transfer direction of the web being transferred; and
a heating unit having a first roller that includes a first heater disposed within the first roller and is configured to heat the web that has been cut.

2. The sheet manufacturing apparatus as set forth in claim 1 , further comprising a second cutting unit configured to cut the web along the transfer direction of the web, the second cutting unit being arranged on the downstream side in the transfer direction relative to the heating unit.

3. The sheet manufacturing apparatus as set forth in claim 1 , further comprising a cooling unit configured to cool the web, the cooling unit being arranged between the heating unit and the second cutting unit in the transfer direction.

4. The sheet manufacturing apparatus as set forth in claim 1 , wherein
the heating unit is configured to cause the fibers included in the web to bind to one another, with the resin interposed therebetween.

5. The sheet manufacturing apparatus as set forth in claim 1 , further comprising a preheating unit that includes a second roller configured to heat the web at a lower temperature than the heating unit, the preheating unit being arranged between the web forming unit and the first cutting unit in the transfer direction.

6. The sheet manufacturing apparatus as set forth in claim 5 , wherein
the second roller has a second heater disposed within the second roller.

7. The sheet manufacturing apparatus as set forth in claim 6 , wherein
the second heater is provided to a rotational axis center part of the second roller.

8. The sheet manufacturing apparatus as set forth in claim 1 , wherein
the first heater is provided to a rotational axis center part of the first roller.

9. The sheet manufacturing apparatus as set forth in claim 1 , wherein
the first cutting unit is configured to cut the web along a cutting position that extends in a perpendicular direction perpendicular to a transfer direction in which the transferring unit is configured to transfer the web.

10. A sheet manufacturing apparatus, comprising:
a web forming unit configured to form a web that includes fibers and a resin;
a transferring unit configured to transfer in a transfer direction the web that has been formed;
a first cutting unit configured to cut the web in a direction intersecting with the transfer direction;
a heating unit arranged downward in the transfer direction relative to the first cutting unit and having a first roller configured to heat the web that has been cut by the first cutting unit; and
a second cutting unit arranged downward in the transfer direction relative to the heating unit and configured to cut, along the transfer direction, the web that has been heated by the heating unit.
