Abstract

A sheet manufacturing device includes: a feeder configured to feed a sheet; and a transferring unit configured to transfer carbon nanotubes with a predetermined length onto the sheet, the transferring unit including: a drawing unit configured to draw the carbon nanotubes from a grown form of the carbon nanotubes in a direction intersecting with a feeding direction of the sheet; and a cutter configured to cut the drawn carbon nanotubes.

First claim

The invention claimed is:

1. A sheet manufacturing device configured to manufacture a carbon nanotube sheet with carbon nanotubes transferred on a first sheet, the sheet manufacturing device comprising:
a feeder configured to feed the first sheet; and
a transferring unit configured to transfer the carbon nanotubes onto the first sheet, wherein the carbon nanotubes transferred on the first sheet have a length exceeding a width of the first sheet, and the width of the first sheet is a width between two longitudinal edges of the first sheet,
the transferring unit comprising:
a drawing unit configured to draw the carbon nanotubes from a grown form of the carbon nanotubes in a direction intersecting with a feeding direction of the first sheet from one of the longitudinal edges of the first sheet to the other one of the longitudinal edges, wherein the carbon nanotubes are drawn until front ends of the carbon nanotubes go beyond the other one of the longitudinal edges; and
a cutter configured to cut the carbon nanotubes drawn by the drawing unit at a position off the first sheet to form rear ends of the drawn carbon nanotubes such that the carbon nanotubes transferred on the first sheet have the length exceeding the width of the first sheet.

2. The sheet manufacturing device according to claim 1 , further comprising:
a separating unit configured to separate a second sheet from a raw sheet comprising the first sheet and the second sheet that has been temporarily attached to a surface of the first sheet;
a diverting unit configured to divert the separated second sheet; and
a laminating unit configured to laminate the second sheet onto the carbon nanotubes transferred on the first sheet.

3. The sheet manufacturing device according to claim 1 , wherein
the feeder is configured to feed the first sheet laminated with the carbon nanotubes aligned along the feeding direction of the first sheet, and
the transferring unit is configured to transfer the drawn carbon nanotubes onto the first sheet.

4. A sheet manufacturing method for manufacturing a carbon nanotube sheet with carbon nanotubes transferred on a first sheet, the sheet manufacturing method comprising:
feeding the first sheet; and
transferring the carbon nanotubes onto the first sheet, wherein the carbon nanotubes transferred on the first sheet have a length exceeding a width of the first sheet, and the width of the first sheet is a width between two longitudinal edges of the first sheet,
the transferring comprising:
drawing the carbon nanotubes from a grown form of the carbon nanotubes in a direction intersecting with a feeding direction of the first sheet from one of the longitudinal edges of the first sheet to the other one of the longitudinal edges, wherein the carbon nanotubes are drawn until front ends of the carbon nanotubes go beyond the other one of the longitudinal edges; and
cutting the carbon nanotubes drawn by the drawing at a position off the first sheet to form rear ends of the drawn carbon nanotubes such that the carbon nanotubes transferred on the first sheet have the length exceeding the width of the first sheet.

5. The sheet manufacturing method according to claim 4 , wherein
the feeding the first sheet includes feeding the first sheet laminated with the carbon nanotubes aligned along the feeding direction of the first sheet, and
the transferring comprises transferring the drawn carbon nanotubes onto the first sheet.
