Patent ID: 8794289

Claim:
An apparatus for making a carbon nanotube film, comprising: a substrate holder configured to support a substrate on which surface a carbon nanotube array capable of being grown, and being drawn to form the carbon nanotube film; a bar supply device supplying at least one bar comprising a first bar, the first bar being configured to be attached to a first part of the carbon nanotube film; a carrier device supplying at least one supporting element comprising a first supporting element, the first supporting element being configured to place the carbon nanotube film and to move up and down; and a stretching device comprising a fixing device configured to seize and move the first bar to draw the first part of the carbon nanotube film from the carbon nanotube array over the first supporting element to form a second part of the carbon nanotube film suspended over the supporting element, wherein the first supporting element on the carrier device is adjusted to adhere the second part of the carbon nanotube film thereto, after the second part of the carbon nanotube film is suspended over the first supporting element.
