Abstract:
A process for treating and heating a porous carbon-fiber material which comprises the steps of: passing said material on a first supporting conveyor belt through a processing apparatus having at least two conveyor belts, transferring said material from said first material supporting conveyor belt to a second material supporting conveyor belt by providing a gas flow to a lower face of said material by a blower and a cylindrical roller with an internal low pressure non-rotating duct to provide thereby a gas pressure or support across a gap between said conveyor belts to thereby float the material across said gap, passing said material through a heating section in said apparatus whereby a heated gas is blown through said material to drive heat deeper into said material and thereby reducing the heating time required to carbonize said fiber material, subsequently cooling said fiber material and removing it from said process apparatus.
