Abstract

A sheet manufacturing apparatus can determine if the sheets supplied as feedstock have already been recycled. The sheet manufacturing apparatus has a supply unit configured to supply feedstock; a defibrating unit configured to defibrate the feedstock; an depositing unit configured to deposit defibrated material defibrated by the defibrating unit; a forming unit configured to form a sheet from a web laid by the depositing unit; a marking unit configured to apply a mark to at least one of the web and the sheet; and a reading unit configured to read the mark imparted to the feedstock when a sheet having mark imparted thereto is supplied as the feedstock.

First claim

The invention claimed is:

1. A sheet manufacturing apparatus comprising:
a forming drum into which fiber and resin are loaded, the forming drum being rotationally driven to mix the fiber and the resin to generate a web material and the forming drum having a hole from which the web material is passed through;
a belt being disposed under the forming drum, the web material which is passed through the hole being deposited on the belt;
a roller downstream in a transportation direction of the web material from the belt having an uneven surface, the roller applying pressure on the web material so that a mark is formed on the web material; and
a cutter downstream in the transportation direction of the web material from the roller which cuts the web material at a specific length so as to provide a sheet.

2. The sheet manufacturing apparatus according to claim 1 , wherein the resin is a fusion bonding resin.

3. The sheet manufacturing apparatus according to claim 1 , wherein the belt is a mesh belt.

4. The sheet manufacturing apparatus according to claim 1 , further comprising a suction device, wherein the mixture is deposited on the belt by the suction power of the suction device.
