The invention relates to a method and apparatus for producing aligned carbon nanotube thermal interface structures using batch and continuous manufacturing processes. The processing apparatus main unit is formed with a unit reception section and one of sheet ejection units different in specifications can be attached to the unit reception section. The second rail forms two first sliding portions and two second sliding portions. The mail box also includes L-shaped brackets secured to inner surfaces of the front and rear walls and a support shelf positionable within the housing. In addition, the first array of transducers and the second array of transducers maintain an orientation perpendicular to the moving direction of the wooden member as the first roller device and the second roller device roll along the wooden member.
